- 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?
Thanks, Jesse

- 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

- Samsung Blu-ray pre-orders incredible: Java Blu-ray authoring in high demandNotes 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."

after removing gtk2-engines-smooth eclipse started to work again.

- Java server accessI have a javaApplet that needs to access a directory on the server, list
the files in directory, then access the selected file. My first idea
was to use a servlet on the server then I found out that the server that
this needs to work with doesn't support servlets or Tomcat. The server
supports PHP and CGI and the hosting company does not want to add java
support.
Can anyone give me an idea on how to go about this?

- 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.

- 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.
So confused, Scott

- 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,
Gert Vanthienen

- identical JPanels, repetitive
I need to make a tabbed pane with four tabs, each pane shows text and
images from a List<Room> collection.
I can manually create the four tabs from the netbeans GUI builder, and
maybe use some copy paste so that the four tabs are similar if not
identical.
Staying within the GUI builder, how would four identical JPanel's, which
make up the tabs for a JTabbedPane, get created?
Could I somehow make a JList show as tabs?
thanks,

- 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

- Export ApplicationHello.
I am using Netbeans 3.5 IDE and have created several applications which is
fine and dandy. The only thing I cannot do is work out how to export these
apps to another PC i.e. to run them on a machine without having the IDE
installed. I believe this would be via a JAR file but cannot seem to get
these to work. Any help in this area would be great as I am going round in
circles. Also, how do I encrypt the code ?

java-programmer, Encryption & Decryption
Hi 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?

It is a maze of new vocabulary, acronyms, abbreviations, and scattered
documentation. The number of assorted bits and pieces that you need to
actually assemble boggles the mind.
Thankfully, there are some good samples at bouncycastle.org in their openpgp
directories.
And that's just the encryption part. JavaMail should be handy for the actual
message part.
I just use it, I don't claim to understand it beyond that it does what we
need it to do and I managed to make it work.
Good Luck!

Will Hartung

There is an important constraint for an encrypted e-mail -- the bytes must
all be legal ASCII characters or the e-mail system will balk at accepting
it. This is why file attachments to e-mails are seemingly so large.
So add this to your list of requirements that the encrypted message must
meet.

[I am no expert in cryptography, mind you. ;)]
Mostly. What usually ends up happening is you use the public key to
encrypt a secret (symmetric) key, and use that secret key to actually
encrypt/decrypt the document. Reason being public key encryption is
super costly, and (from what I remember) the resulting ciphertext grows
exponentially. (If not exponentially, than say "more than you'd want it
to").

It's scattered all over the place. One place you might want to look for
more current/powerful encryption in Java is here:
http://www.cryptix.org/
It looks like their site is down, but you can still download the libary.
Also, don't forget to get the "Java Cryptography Extension (JCE)
Unlimited Strength Jurisdiction Policy Files" from Sun if you plan to
use JCA.

Taking this literally,
1. up to you, can you type?
2. use the unix command "crypt" like this
"crypt < myfile > newfile"
3. use any common thing like Outlook Express
4. use the unix command "crypt" (call user and ask for the magic word)
5. up to you, don't forget your glasses

- Problem with deploytool.I am trying to build a web service starting from hand-written wsdl using
JAX-RPC and wscompile tool from Sun Java System Application Server 8.0.
I don't want any data binding, so i invoke wscompile tool with -f
nodatabinding option with deploytool I create war, and I try to deploy it.
And deployment fails!
Reading server log I have found that reason for this failure is ejbc:

Identifiers are polish words, so don't bother with making up what do
they mean.
I have checked mapping.xml generated by wscompile, and ejbc is right -
there is nothing about rodzajProblemu, but if there is no class bound to
element problemPrzetwarzania except SOAPElement, there is no mapping,
so deploytool shouldn't try to compile any bean!
Should I consider it to be bug or I am doing sth. wrong?

I think that's the point of neural nets. You just develop a general
mechanism that "learns" from input--similar to how our brains do.
We aren't anywhere near achieving the complexity of the human brain,
yet, but we will get there eventually.
And THEN we'll see if true intelligence is an emergent property of
complexity (possibly) or whether it requires something more than
mere machinary (possibly).
Until then, we're all just guessing. (-:

The irony is that I believe Mr. Green experienced what most
theologians would call a "conversion experience" (with dolphins)
and now, like many, many of the converted, is something of a
fanatic on the matter. His posts have more a sense of preaching
than of discussing, and--as you note--he is intolerant of the
"non-believers".
[shrug] Which is fine. Takes all types to make a world, and it's
good to have people on the Side of the Animals. As you can see
from the volume, the thread has certainly captured people's interest.

- web browser plugin problem .... JRE not found?Hello,
I'm trying to load a Java 1.2 applet into IE 5 using the browser plugin.
When I do so, I get an error message telling me that the plugin cannot find
the JRE where in the path specified (ie., the path to which I just installed
the plugin).
What's going on here?
TIA,

- GUI Object DesignI am pretty new to Java and I am trying to get my hands around OOD.
In the course of designing a GUI, I am working on breaking down the
components into the necessary objects so that the code will be as
versatile as possible.
As I work through it though, I am confronted with the situation where
I feel that I am over analyzing and creating too many objects.
Let's say that I have a pretty basic window application. It has a
window with a menu bar and three menus, each with a few items.
The main window is an object inherited from JFrame.
Is it best to make the menu a seperate object, inherited from
JMenuBar, and then make each menu a seperate object, inherited from
JMenu, and then make each menu item a seperate object, inherited from
JMenuItem? Or, is a lot of this typically placed within a single,
larger object?
I guess I am wondering where you draw the line. How do I know when I
have gone too far and am creating too many objects unnecessarily?
I imagine a lot of this dicussion is personal preference and some
aspects are open to debate. I am just looking for some guidance as I
learn more about this.
Thanks.

- Java Applet Parameter LimitHi all,
I would like to know the maximum number of parameters that can be passed
to an applet. While I think there is no theoretical maximum, I believe
there to be a practical limitation for browsers.
I am using winXP, IE6 and firefox1, and jre1.4.2.
I have a graphing applet which works very well except when there are a
large number of parameters i.e. 5000. When I load such an example with
appletviewer the applet opens fine. However when I load the same applet
in either IE6 or firefox1 then nothing happens except the page appears
to be loading but gets no where even if you leave it for hours - in
other words the browsers seem to hang. Java does not appear to load into
memory - the icon does not appear in the system tray which leads me to
believe that it is a browser limitation, rather than a java one.
Does anyone know if there is such a limitation? Do you think it could be
remedied by merging the tags - i.e. having less but longer params? Or is
there another way of passing data to the applet?
Many thanks,
Chris.

- Making Form results readableI have coded a simple form that sends the results to an email. The
form works, but when I recieve the data it is all together in one big
line. What kind of coding do I need to do to separate the data and
label it as well. Do I need to create some sort of template in
notepad??? I am a very beginner coder.
Thanks,
Lindsay
