Sure. Beware though, that I have a lot of remarks; also about coding
style and readability. It's a long read, but worth it (IMNSHO).

- This name is confusing: it is an outer class with "inner" in the name...
- Please start class names with an upper case letter as in the JDK; when
most Java programmers read a name starting with a lowercase letter, they
expect a variable.

This main method does nothing, unless you do everything in the
constructor. That is, your program runs when you create an object. This is
confusing.

This indentation is hard to read; you may use a bit more: 4 spaces or so.
If you run into the right margin, your code is most likely too complex.
Note that indentation, brace style, etc. is very personal, and has caused
many "holy wars" in the past. However, if it's readable, it's good.
Otherwise, it isn't. Opinions differ on what's readable though...

This is the heart of the problem:
- t and tt are member variables, as they are defined outside any code
block.
- t.somefunc(tt) is a method call, but is outside a method, constructor or
even an initializer block. The compiler is expecting a definition for a
member variable, constructor, method or initializer.
You could make it work in several ways. Your goal is to understand why
option 2 is preferable.
Option 1:
- Double the braces in the definition of class test1. This creates an
initializer block that makes the lines inbetween into an anonymous
constructor that is always called when instantiating this class.
Option 2:
- Change the content of inner1#main(String[]) to:
test1 testObject = new test1();
testObject.callMethod();
- Perform the change of option 1.
- Between the two opening braces of the class test1, add this:
public void callMethod()
- Reformat the code (especially the class test1).
Regardless of which solution you choose, I advise you to read up on Sun's
coding conventions. Note they're just guidelines: you don't have to agree
with them. However, it helps if you follow them.
The URI is: http://java.sun.com/docs/codeconv/html/CodeConvTOC.doc.html
Following them won't make you a better programmer, but it will help both
you and others to understand your code more easily. This in turn enables
you to get help more easily, and thus learn more.

- java.net.ServerSocket doesn't catch every connectionHi,
My problem is that ServerSocket.accept doesn't catch every connection
made to the socket.
I wrote a little server that gets a connection and spawns a new thread
giving the ServerSocket as parameter to the constructor. Then the
Thread is start()'ed.
The Code is:
ServerSocket serversock = new ServerSocket(port);
while (true) {
Socket socket = serversock.accept();
HandleSocket hs = new HandleSocket(socket);
hs.start();
}
But this code does not catch every connection that will be made to it
and I get a timeout with
the client application. If I retry connection it often works, but the
problem happens randomly.
I can't find anything, that could cause this problem. I'm really a bit
disappointed. I wrote the same application with C++ and had no
problems. But I need it platform independent, thats why I want to use
Java.
Anyone had this problem before? Can anyone help me?
Thanks in advance

- Nio performance bottleneckHello !
In order to be sure that nio package was more performant than regular
streams, i have tested it with this little piece of code :
// ----------------------------
ByteBuffer loWriteBuffer = ByteBuffer.allocateDirect(1024);
CharBuffer loBuffer = CharBuffer.allocate(512);
Charset charset = Charset.forName("ISO-8859-1");
CharsetEncoder encoder = charset.newEncoder();
long llMillis, llMillis2, llMillis3;
llMillis = System.currentTimeMillis();
try {
FileChannel loChannel = new RandomAccessFile(new
File("C:\\Temp\\Test.txt"), "rw").getChannel();
for (int i = 0; i < 1000; ++i) {
loBuffer.put("ceci est un test\r\n");
loBuffer.flip();
encoder.encode(loBuffer, loWriteBuffer, false);
loWriteBuffer.flip();
loChannel.write(loWriteBuffer);
loBuffer.clear();
loWriteBuffer.clear();
}
loChannel.close();
}
catch (IOException leIO) {
leIO.printStackTrace();
}
llMillis2 = System.currentTimeMillis();
try {
Writer loWriter = new BufferedWriter(new OutputStreamWriter(new
FileOutputStream("C:\\Temp\\Test2.txt"), charset));
for (int i = 0; i < 1000; ++i) {
loWriter.write("ceci est un test\r\n");
}
loWriter.flush();
loWriter.close();
}
catch (IOException leIO) {
leIO.printStackTrace();
}
llMillis3 = System.currentTimeMillis();
System.out.println("Results : nio = " + (llMillis2 - llMillis) + " ms /
standard = " + (llMillis3 - llMillis2) + " ms");
// ----------------------------
I was surprised to see that, on my computer, the regular stream based part
was running about 4 times quicker than the nio based part !!
Here is my question : is my code correctlty optimized ? Anybody already
noticed this performance bottleneck ? Is my test the cause of this problem ?
Thank you !

- JavaScript redirect and JSP submitHi,
I've been trying to get the right way to send parameters to a JSP from
a HTML form. The referred JSP must get the values of the selects form,
because it executes queries and does stuff with that values. But the
only thing I've got it's a Tomcat error report.
The menu.jsp is something like this:
... // HTML stuff
<script language='JavaScript'>
function valida()
{
var ok=true;
var indexAccion = document.forms[0].accion.selectedIndex;
var indexTablas = document.forms[0].tablas.selectedIndex;
var indexBDatos = document.forms[0].BDatos.selectedIndex;
if (indexAccion==0 || indexTablas==0 || indexBDatos==0)
{
alert("Elige un criterio");
ok=false;
}
if (ok)
document.forms[0].submit();
window.location.href =
document.forms[0].accion.options[indexAccion].value;
}
</script>
... // HTML stuff
<form method='post' ***SHOULD BE THE accion.selectedIndex.value***>
<select name="accion">
<option value="inicio" selected>Selecciona una opcion
<option value="visualiza.jsp">Visualizar registros de la tabla
<option value="modifica.jsp">Modificar registros de la tabla
</select>
<select name="tablas">
<option value="inicio" selected>Selecciona una tabla
<option value="tbl1">Tabla 1
<option value="tbl2">Tabla 2
</select>
<select name="BDatos">

<option value="db1">Base 1
<option value="db2">Base 2
</select>
<br><br><br>
<input type="button" value="Aceptar" onclick='valida()'>
</form>
Any ideas to figure it out?

- Database access for server and clientI am trying to create a small Internet application to access a mySQL
database on specific client machines around the country and query their
database and send the query result to our web server and then process
further data on the web server. Here is the layout: There are
several client machines around the country that have a mySQL database
installed and will give us certain query privileges for this database.
I need users on these client machines to be able to run an Internet
application from our web server which queries their local database and
then sends information to our server.
I see two options: a trusted, signed applet or a full java application
- also digitally signed - that is deployed through the Java Web Start
technology. (This is a very simple query on the client with a simple
drop-down list for the user to select from the query result - nothing
complicated.)
Does anybody have any suggestion as to which method is preferable? The
end users who will be running this application are not very computer
savvy and might not be able to figure out browser messages like "Your
browser understands the <APPLET> tag but isn't running the applet, for
some reason." For this reason I thought that the Java Web Start method
might be preferable, but I have no idea how reliable this method is and
what kind of kinks I will have to work through.
I also wonder if the Microsoft .net environment might offer an
alternative (our web server is Microsoft IIS and the clients are all
Windows XP or Windows 2000).
Any thoughts?
Thank you.

- Difference in opinion with look and feel !Hi,
I have an interesting problem while using the look and feel. This is my
function:
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
Well the tool bars, the menu are all system's look and feel. i.e i am
using Windows OS. so i get all windows look and feels. But when i use
the file chooser, I get an open dialog box with look and feel of Sun
Microsystems' solaris.
Does anyone have any idea why this is coming up like this?
Interestingly I am not even able to reproduce this an other project.
Plz help,
Thank you,

- Eclipse 2.1.1 does not save my workspaceHi,

- Translator Tools? I was about to throw in the towel on this
project I've inherited. It's about 5,000
Java files, totally undocumented and uncommented.
I asked and looked for tools that would help
me make sense of this mess, so far to no avail.
Now the owner of the company is willing to
consider redoing it in C++. ( In my opinion
there was no good reason for the previous software
engineer to write this in Java. It's a pretty
straightforward Windows desktop app that would
be much easier to understand and maintain had
it been written in VC++. There's some evidence
he chose Java just so he could get some experience
with it,)
Anyhow, I'm not rewriting this by hand.
I came across the following in Bruce Eckel's
'Thinking In Java', "I've even heard it
suggested that you start with Java, to gain the
short development time, then use a tool and support
libraries to translate your code to C++, if
you need faster execution speed."
Has anybody heard of or better still used
such translator tools? Even if it only did
80-90% and the rest required manual intervention
it might work.
TIA for any advice.

- Eclipse jboss toolsHi,
has been any efforts to ports jboss tools plugin for Eclipse?
It contains some parts written in C (i think having to do with GUI editors).
Using eclipse-devel 3.3.2 and jboss tools 2.1.1 (previously known as JBossIDE and
now commercially named as "Jboss developer studio).
Installing the jboss tools plugins from within eclipse, asis, results in a highly unstable eclipse
environment.
Any ideas?

- Java String.replaceAll() not behaving as expectedGiven a string "s", I'd like to convert all the line separators into
their "escaped" string equivalents. i.e. a dos/windows newline gets
converted into the literal string "\r\n".
I tried this in my java code...
s = s.replaceAll("\n", "\\n");
s = s.replaceAll("\r", "\\r");
but I end up with "rn" instead of "\r\n"
I assume the problem has something to do with the regex pattern
replacement but it seems like it should work.
What am I doing wrong?

- How to create same RSA signature objects in Java and C#Hello,
I have looked through the documentation for the Java and C#
security classes, and I can't find an answer to the following question.
How can the same RSA signature object (class java.security.Signature in
Java
and System.Security.Cryptography.RSACryptoServiceProvider in C#)
be constructed?
What I would like to see is that signatures generated in Java are
recognized as valid by C#, and vice versa. I am assuming this implies
that the RSA signature parameters must be the same in both
languages, but I can't figure out how to make that happen.
According to some sketchy notes I've found through googling,
it is possible, so I'll keep trying. Thanks for any information.

- JAVA RMI thr HTTP throws NoRouteToHostExceptionHi,
I am developing an application that would be used in a firewall
environment. As part of my test environment, I have blocked port 1099
and have allowed port 80 access on the server. So all the RMI calls
from the client should be tunnelled thru port 80 in the server.
I have ported the java-rmi.cgi script (unix version) to windows
version. So I am confident that my RMI client, java-rmi.cgi are
correct. But I am getting NoRouteToHost Exception and my application
has to exit.
My understanding is that when the RMI client tries to connect 1099 (rmi
port) and if it fails, it will try to connect to port 80 and later all
the rmi calls should be embedded within http commands. Does my
web-server (apache) needs to be configured for this?
I have also tried setting http.proxtHost, but of no avail.
Please let me know of your solutions.

java-programmer, Samsung Blu-ray pre-orders incredible: Java Blu-ray authoring in high demand
Notes on initial responses to Samsung blu-ray launch, people already
buying players before content, and Java BD-J authoring of Blu-ray discs
* Posted while eating late lunch on Nokia 9300 and Opera Mini Java
browser.
http://bluray.highdefdigest.com/news/show/Sony/Samsung/Hardware/Blu-ray_Assault_to_Begin_Samsung_Proclaims_Incredible_Pre-Sales/111
Blu-ray Assault to Begin; Samsung Proclaims 'Incredible' Pre-Sales
After months of speculation, excitement and street date delays, the
Blu-ray
format is set to launch over the next week amid a flurry of marketing
hype
for the format's first player and discs.
Samsung began shipping its first stand-alone Blu-ray disc player, the
BD-P1000, to stores last week in anticipation for its on-sale street
date of
June 25. Sony will prime the pump for the player's debut by issuing
its
first seven Blu-ray disc titles tomorrow, June 20; Lionsgate will
launch its
support for Blu-ray with another six titles on June 27.
Samsung plans to have its player in over 2,000 storefronts nationwide,
including such major chains as Best Buy and Circuit City. In
conjunction
with Sony, the companies will also provide demo players and discs to
retailers to offer side-by-side comparisons with rival HD DVD in order
to
subjectively sell the format to potential consumers.
The electronics manufacturer also claims that interest in the BD-P1000
and
Blu-ray so far has been strong. "Pre-orders have been incredible,"
Samsung
spokesman Jose Cardona told Video Business.
---------------------------------------------
http://www.tgdaily.com/2006/06/20/sony_pictures_blu-ray_movies_today/
With Toshiba having launched its HD-A1 and HD-XA1 HD DVD videodisc
players
in April, Samsung is preparing to be the first brand to formally
launch a
competitive Blu-ray Disc player in North America, with its BD-P1000
set to
premiere on Sunday. Despite that firm date, customers nationwide are
already reporting having purchased BD-P1000s from Best Buy store
shelves -
just sitting there nonchalantly like any other DVD player, as if shelf
stockers didn't know the difference. But today, those early adopters
will
finally be able to play real BD media - not just upconverted SD media
- as
Sony Pictures releases the first batch of BD movies today.
Video outlets today should already have received, and will likely have
displays ready for, 50 First Dates (Adam Sandler, Drew Barrymore),
Hitch
(Will Smith), House of Flying Daggers, the original Terminator, the
sci-fi
"new cult classic" The Fifth Element (Bruce Willis), Underworld
Evolution,
and XXX (the film, not the rating). One title, A Knight's Tale,
originally
scheduled for release today, is being pushed back to 25 July. The
high-energy motorcycle violence film Ultraviolet joins the line-up
next
Tuesday. Lion's Gate Home Entertainment is due to follow up next
Tuesday
with the BD releases of 2006 Best Picture Crash, Terminator 2:
Judgment Day,
the horror flick Saw, Lord of War (Nicholas Cage), and the Marvel
Comics
vigilante piece The Punisher.
------------------------------------------------------------------
Java: Brave New Disc-Authoring World
http://www.pcworld.com/news/article/0,aid,126163,00.asp
Blu-ray Disc relies on BD-Java (BD-J) for its disc-authoring
environment;
HD DVD uses Microsoft's XML-based iHD, or Internet High Definition. "I
think
BD-J is better future-proofed," says Eklund. "But it is complex," and
implementing it properly will take more time, he says.
The switch to BD-J required adding programmers and engineers to the
disc-production mix.
BD-J has two different profiles. Sony's first content will be in what
Eklund
refers to as BD-MV, or "movie mode." "The menus will still be quite
different than what you're accustomed to with DVD," he promises.
"BD-MV is a
powerful format for creating interactive menus, and it will give a
better,
more seamless experience than what users are getting from DVD. You
don't
have to jump around between menu pages as you do with DVD. We use a
graphics
layer to present all of the text information, so you don't have to go
back
and access the disc in order to access the menus. We also have a tool
called
a pop-up menu that the user can use to access disc features during the
movie's playback, so, for example, you can get to a commentary track."
As powerful as BD-MV is, it has its limitations. "We are currently
still
investigating how we're going to author picture-in-picture content,"
says
Eklund. "But I'm sure we will be exploring that later on in the year."

Only the initial group of titles from one of many studios. Hold on to

How many times are you going to use a FORUM as some sort of proof.
There are obviously two camps here, and citing a forum filled with both
sides is not considered "proof" of anything.
I cite news reports showing that HD-DVD is falling flat on its face,
with slow sales and Warner cutting HDDVD titles, you give me a FORUM.
Great job.

Design. The industrial design of the Samsung is far superior to that of
the HD-A1 in several ways. The sleek, piano-black box has a tapered
look; a circular, pressure-based front navigation panel; comfortable,
lightweight remote control; and a 10-in-2 card slot reader for reading
photos or MP3s. The player even resumes disc playback where you left
off, whether you press stop, or you power the unit down-a nice touch.
Responsiveness. Again, the Samsung rates ahead here. Across a variety
of standard definition and high definition films I threw at it, the
Samsung was generally fast at navigating around and titles and menu
options, and the remote's soft-mold buttons responded to my commands
in a timely fashion. Sometimes, the Sony BD discs I tried (including
House of Flying Daggers and Fifty First Dates) were a bit sluggish when
accessing chapters, but this problem did not seem evident with
standard-def discs, which leads me to believe it's an issue with the
discs, not the Samsung player.

I'll say it one more time, fucktard. My machine is ALSO under
Linux, and also works with interactive discs, even that type of media
on std DVDs.
Get off your low horse, retard.

You're an idiot. They are reviews by VIDEOPHILES that bought the
machines! As well as folks that were given players FOR review.

No. YOU drew that conclusion. The news merely stated a slight
slowing in sales.

>Great job.
Warner isn't "cutting" anything. It is ONE option of the many they
have, and losing money is kinda stupid. Remember "Field of Dreams"?
Here's one for you:
"If you press it, they will buy (it)." Warner isn't going to shoot
themselves in the foot.
You are an idiot.

So....the lack of sales of HDDVD is telling...right? And the reportedly
very strong pre-sales orders for Samsung's Blu-ray player is also
telling, right?
And btw, being foul-mouthed and repeating all the time that someone is
an "idiot" with no particularly congent argument to back this up makes
YOU look like the idiot.

Going to a forum where there are opinions from both sides of the
fanbase is not as enlightening as going to a non-biased review (and i
provided one link from PC mag where the reviewer clearly favored
Samsung's Blu-ray). There seems to be a faction that desperately wants
HDDVD to succeed and Blu-ray to fail. Unfortunately for this faction,
they're not going to get their wish.
Content is everything, and the LACK of content for HDDVD is again,
telling. It sucks when most studios back the other side....

You obviously don't know anything about AVSForum. It's where hardcore
home theater enthusiasts and many industry representatives discuss the
intricate technical workings of new products.

A PR release from Samsung is not a "news report", dumbass.

Your logic astounds me. By your reasoning, hearing opinions from both
sides of the argument is less helpful than reading heavily biased
articles likely paid for by one of those sides? Fascinating.

It does seem weird to me, too. Even he thinks AVS Forum has opinions on
both sides of the issue. And if both sides are represented, then if the
BD-1000P were significantly better than (or even as good as) the HD-A1,
there would be a *lot* of people saying just that.
Since it's clear from AVS Forum posts that the first Blu-Ray player isn't
worth the $1,000 price tag, and that the first HD-DVD player is a better
deal, either everybody there is an HD-DVD shill, or the BD-1000P just isn't
that good. When you go back and look at previous posts where people tout
how much better Blu-Ray will be, and now turn an about face when they get
the actual player and movies, that says that even the Blu-Ray supporters
are disappointed, which is a bad, bad sign for the format.

It is the consumer that will determine the ultimate winner in the
HD-DVD vs. Blu-Ray battle. Consumers don't know and don't care what
format MS, Java, Linux, etc are standing behind. What consumers care
about is cost. When they walk into a BestBuy/CircuitCity store and see
one unit selling for $1000 and another unit for $599 they will buy the
less expensive model.
They won't care which one has marginally better quality video. Most
people can can tell the difference between standard video and HD but
few consumers will be able to discern the subtle difference in quality
between these two formats. The difference in price... that's something
they understand.
At current prices not enough of either format will be sold to determine
the outcome. The real battle will be to see which format can break the
$399 barrier first. My prediction... first player to sell for $399 or
less will be the winner.

Well, more from the HD-DVD side than BR.
Yes the widespread opinion is the first Sony Blu-Ray releases are
disappointing.
But is that reason to dismiss the format? Were DVD releases always
pristine from the start?
Also, will MS always handhold the HD-DVD encoding and authoring?

Most. Let's just say the BluTurd is looking a lot like the first

The encoding is by the Motion Picture Experts Group.
Authoring? The studios...

It is weird. I've not been impressed with the hi-def feeds of the World
Cup that I've seen. Is it the monitors used, or some limitation in the
feeds? I though HD would be sharp, but I've only seen that one time --
in a museum exhibit a few years ago.

Unless you are getting it "off air" it has been reprocessed. In
other words, if it is coming off cable, it ain't true HD anymore.
Satellite HD still IS, as well as off air HDTV content from local
broadcasters. In such cases, one can tell exactly how many grams of
grass stain have been shoved into the player's jersey shoulder.

"Most" as in, "a lot were still non-anamorphic transfers taken from

OTA isn't technically "true HD" since it's still MPEG2 compressed. It's
usually the best looking though, since all other live feeds are taken from
that stream. Unless you're talking about something other than network
material.

- Accessing a Java COM component from .NET.NET framework 1.2
Hello.
We've been accessing a Java COM component from classic ASP for a while now,
which works fine. We now need to access it from .NET, but we have no idea
how to reference this component as we can't find the .dll (or whatever type
of file Java COM components compile to). We do know a couple of things
about the component:
CLSID: {E7DEFE93-E26E-11d2-B3A0-0000E8512796}
Component name: PaymentClient.com.COMClient
Searching the registry for either string yields results, but the only DLL
referenced is msjava.dll which is obviously not what we're looking for.
Can someone give us any hints on how to access this object from .NET.
Thanks,
Mike

- Displaying error values with Struts Validator FrameworkHi,
I'm using the struts validator framework to validate an email address
in a form.
If the user enters an invalid email address (ie
invalidEmailAddress.com) I'd like to display the following error
message:-
"invalidEmailAddress.com is an invalid e-mail address"
However all I seem to be able to do with the validator framework is
output the following:-
"Email address is an invalid e-mail address"
with messageResources.properties and validator.xml set as follows:-
validator.xml:-
<form name="addressForm">
<field property="emailAddress"
depends="email">
<msg name="email" key="errors.email" />
<arg name="email" key="form.address.label.emailAddress" />
</field>
</form>
messageResources.properties:-
errors.email={0} is an invalid e-mail address.
form.address.label.emailAddress=Email address
I'm using <html:errors /> to output the error list in a jsp.
Is there any way to substitute the actual entered value into the
errors.email message using the struts validator framework? I know it
can be done in the validate() method of the ValidatorForm class but
it there method of simply using the validator framework?
Thanks in advance for your help.

- Encryption & DecryptionHi all
I've been asked to look into the encryption and decryption of attachments
sent in emails. The specific scenario is as follows:
- a file is created
- the file is to be encrypted
- the file is attached to an email and sent to a recipient
- once received, the file should be decrypted
- the file is read
At first glance, I think I should be reading up on the JCA (Java
Cryptography Architecture) and use a public key encrypt and a private key to
decrypt. Is this right?
Are there any online implementations or tutorials that you would suggest I
read to learn more about this?

- Eclipse Runtime ErrorI am running Eclipse 3.1.1. I created a project, called PizzaShop.
Inside pizza shop, I have src\ lib\ and build\classes\ folders. Inside
src\, I have a pizza folder for the pizza package. That too is mirrored
in build\classes\pizza.
When I go to debug as ->debug, Eclipse tells me:
java.lang.NoClassDefFoundError: pizza/SystemTest
Exception in thread "main"
What does that mean and how do you tell Eclipse which main to run? I
think I tell it that when it pops open the configuration menu, and I
tell it "pizza.TakeOrder" for the main class to run. But, obviously, it
cannot find the main, and there is a public main() in the TakeOrder
file.

- How Do I Configure a Tomcat Server for Production?Hello,
I am pretty new to Tomcat. I am wondering if there are any standard
configurations that need to be added/modified as part of a Production
deployment aside from database URLs and those types of values.
Currently, we have mostly the same configuration for Production as we
do for development.
As the load increases are there any obvious values that we should be
changing?

- Design question: business delegate or not?L.S.,
We're in the process of developing an application using JSF, Hibernate and Spring and we're facing a design question on which we would like your ideas.
The application has it's own database, which is accessed using Hibernate, for most of it's entities (e.g. Problem), but it also has to work with data from a legacy system.
The legacy data is accessed through a set of Spring components (<bean/>s), which use JMS to exchange XML messages with the legacy system. These services provide us with e.g. Article instances.
The Problem instances, which are retrieved using Hibernate, should hold a reference to an Article. Since Hibernate does not know about the Article class, we have added an articleId property to the Problem class and whenever we retrieve a Problem using our ProblemService class, the ProblemService will look at this property and retrieves the corresponding Article instance.
This process happens for a couple of entities (Article, Supplier, TracingInformation, ...)
This approach however has a number of drawbacks:
1) our Problem class contains several 'duplicate' properties: articleId/article, supplierId/supplier,... leading to confusion
2) resolving the correct Article, Supplier, ... instances happens for every Problem ever instantiated in the ProblemService, causing overhead whever the information is not required by the JSF web client (especially for lists of data)
3) whenever someone adds functionality to the ProblemService, we have to be careful to always fill in the missing entities when a new Problem instance is created
We have thought of two possible solutions so far:
1) creating a Hibernate UserType to convert the article id stored in the database to an Article instance and visa versa
- This approach would solve drawbacks 1 and 3, but doesn't help us much with drawback 2.
- There is another issue with this approach: we need Spring's ApplicationContext in our UserType (<type .../> declaration in Hibernate mapping), but this would require rebuilding the ApplicationContext or having some kind of singleton to obtain the ApplicationContext (it is now created by a web application listener) (unless there is a Spring way of doing this, e.g. using a TypeDefinitionBean)
2) creating a business delegate for the Problem class
- This would solve all drawbacks, since the business delegate could quite easily use the Spring components already available to retrieve an Article instance on the fly when needed
- The business delegate should only have to expose the article property and the object sent to our DAO should only contain the articleId
- The business delegate solve the resolving of the Article, Supplier, ... entities once and for all, so nobody can forget to add these to their newly created Problem instance
The 'Business Delegate' solution seems the most appropriate, but wouldn't it add a considerable amount of extra coding for the features it provides?
Which solution would you recommend? Do you see an easier solution for the problem?
Thank you in advance for any feedback,

- Focusing a JPanel?Is there a way to give a JPanel focus on a mouse click besides explicitly
saying "panel.requestFocus()"? I tried "panel.setFocusable(true)", but it
had no discernable effect. Using J2SE 1.4.2.

- Suspending threads by ThreadPoolExecutorHi all,
Does ThreadPoolExecutor may suspend idle threads ?
I wonder wether suspended threads eat less resources than active ?
I imagine the solution when ThreadPoolExecutore suspends each idle
threat after idleness of 60 seconds and after next 60 seconds of being
suspend the thread got killed ?
Is it reasonable ?
Regards,
Maciej
