- trying to integrate jfcUnit on MavenI have been trying with no success to add the jar jfcUnit.jar on my
maven project. the main problem is that anytime i am trying to build
it. I get the following message:
Attempting to download jfcunit.
WARNING: Failed to download jfcunit.
The build cannot continue because of the following unsatisfied
dependency:
jfcunit
On my project.xml I have defined the jfcunit dependency as follows:
<dependency>
<groupId>commons-cli</groupId>
<artifactId>jfcunit</artifactId>
<jar>jfcunit</jar>
</dependency>
on the file system itself i have inserted this jfcunit on commons-cli
directory. I have also added to the classpath, and I have tried on
eclipse and it works. Nevertheless wnytime i am trying to build a
project sing maven, i am getting the same error.
I would appreciate any help regarding this matter.
Thanks

- FreeBsdCrypt updatedAlas, I don't have the time to make a proper port of this (but if someone
else wants to, please do feel free) but since there's an update and folks
may find this useful, I thought I'd mention it anyway.
FreeBsdCrypt can be found at
http://spatula.net/software/FreeBsdCrypt-1.1.jar . This contains an
implementation of FreeBSD-style MD5 crypt, which many have found useful
when trying to integrate Java stuff with FreeBSD stuff, or migrating from
other languages to servlets, or whatever.
The jar contains all the API docs, source code, and the complied class.
Usage is pretty simple anyway:
String result = FreeBsdCrypt.crypt("password", "salt");
The major change in this version is correcting the way the class name is
capitalized. It needed to start with an uppercase letter since it's a
class name, and then Pascal-casing the rest of it. Consensus on the web
seems to be that acronyms of 3 letters or more are to be Pascal-cased.

- custom jtable copy command?Hi.
I am trying to implement a custom behavior on the copy command on
jtable.
Basically I force the entire row to be selected when a user is working
with myJtable. I feel this is a good design because it allows the user
to quickly see what they are working with, without a doubt.
However I would like to customize the copy command on the jtable
because some of the items in the row are images, which I would not like
to allow the user to copy (it gets converted into text, and it looks
ugly!).
What I would like to do is have the copy command ignore the columns
with the images in them, and only copy the textual columns. Im not
sure how to go about doing this, does anyone have any insight for me?
Thanks!

- Java Axis2 Client Calling .NET 2.0 Web Service..I am able to get the call to the .net 2.0 web service with this code:
[code]
InventoryServicesStub stub = new InventoryServicesStub(null,
"http://localhost:2067/NGLPTOServices_VS/InventoryServices.asmx/Ping");
InventoryServicesStub.Ping ping = new InventoryServicesStub.Ping();
InventoryServicesStub.PingResponse response = stub.Ping(ping);
String results = response.getPingResult();
System.out.println("Response : " + results);
[/code]
I can see it execute in Visual Studio debugger and return. When control
comes back to my eclipse debugger, I get the following AxisFault:
"First Element must contain the local name, Envelope"
How do I fix this?
Here is my WSDL:

- Difference between 1.3 and 1.4 in JTable?Hi,
I wrote an application that uses a JTable to display some data. I wrote
my own cellrenderer that provides rows that contain multiple lines of text.
When a row is deleted all other rows are rerendered and the rowheight para-
meter is updated accordingly. This works in 1.3. But in 1.4 (I tried different
JDKs on different platforms (Linux/MacOSX/Windows..) the rowheights are not
updated. Is there a difference in the evaluation of this in 1.4? Maybe that
I have to change the rowheigth at a later point in the program?

- SETTING POSITIONHello,
I am new to Java and have been practicing by placing graphical shapes on
screen. I would like to know how to choose the coordinates where the shapes
appear within my applet window. I can't seem to find any helpful references
on this seemingly simple task. If anyone could give me details of the method
required I would really appreciate it.
Many Thanks.

- XML QuestionsI have a very simple XML document for settings in an program I have written.
I want to be able to read in and update these settings.
- Would I be better using DOM or SAX?
- What would be the best parser for me?
Also, as I'm new to XML in Java (and also fairly new to Java) I'm still
unsure on what effect exactly implementing XML in my program will have. It's
a very simple program (the java files are 35kb in total) - it appears to me
that if I use XML then I'll have to include a comparatively huge XML parser
with my program when distributing it - I've just downloaded the IBM one and
it's 2.6MB. Is this true or am I misunderstanding something fundamental
here?
TIA.

- Datasource problames + accessing the, outside of a containerHi,
I'm completely new to J2EE and currently struggling with datasources.
We have a Oracle database we'd like to access via jboss. I've set it up as a
datasource using the oracle-xa-ds.xml fiel as an example. This appears to
have worked, in as much as we can now see it via JNDIView .
I'm having no luck actually using it however.
To test I created a servlet containg the following code :-
try
{
ic = new InitialContext();
ic.addToEnvironment("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
ic.addToEnvironment("java.naming.provider.url","jnp://localhost:1099");
ic.addToEnvironment("java.naming.factory.url.pkgs","org.jboss.naming.client");
ic.addToEnvironment("j2ee.clientName", "test");
}
catch (NamingException e)
{
out.println("Could not create JNDI " + "context: " +
e.toString());
}
try
{
DataSource ds = (DataSource) ic.lookup("java:XAOracleDS":);
con = ds.getConnection();
}
catch (Exception ex)
{
out.println("Unable to connect to database. " + ex.getMessage());
}
This fails telling me that test is not bound.
What am I doing wrong?
Our eventual plan is to have applications access this datasource from
outside of jboss. I've seen a couple of posts now suggesting that this might
not be possible. Can anyone confirm if this is the case?
Thanks

- a simple question realted to StringBufferHi,
I am using a StringBuffer to hold a line with fixed length of 72 chars.
Later, I am going to put char at a specified location, using
setCharAt(location, char) method.
But this code doesn't work:
<Java>
StringBuffer line = new StringBuffer(72);
line.setCharAt(5, 'A');
</Java>
This code works:
<Java>
StringBuffer line = new StringBuffer(72);
for (int i=0; i<72; i++) //make the StringBuffer contains 72 empty chars
{
line.append(' ');
}
line.setCharAt(5, 'A');
</Java>
I found that this required for loop is ridiculous. Reading the Java
document of StringBuffer suggests the first version is correct and
should work. I don't understand it.
Thank you very much for your help.

- JList/MouseListenerHi all
I'm using two JLists with the same MouseListener in a JFrame. How can I find
out on which JList the MouseEvent was released?
Is it generally possible or should I use a MouseListener for each JList?
Thanx for your help

- new java.util.Date(0)Hi,
I'm sure this is some kind of Locale issue and is probably documented in the
spec, but I looked there and there are many things documented there. It
would be nice if the experts in this ng could explain the right way to think
about it.
System.out.println(new Date(0));
yields
Wed Dec 31 19:00:00 EST 1969
I guess this is the time in NY (which is what my computer is set to) when in
London it was 1/1/1970 00:00am. How can I use Date more generically?
For example, I have code which returns historical temprature. If I ask it to
return the temprature as of "1/1/1970" it will convert the string to the
Date (which is Date(0)) and then return the temperature as of 12/31/1969. I
could artificially add 5 hours, but then it won't work in CA. I could add 8
hours but then it won't work in Moscow. I could add 1 day, but then it won't
work in London.
Thanks!

- Problem about JavaMailHi,
I'm just trying to use JavaMail and have a strange problem.
(See the code snippet below)
When running it, the exception error message is:
errorjavax.mail.SendFailedException: Sending failed;
nested exception is:
javax.mail.MessagingException: Could not connect to SMTP host: localhost,
port: 25;
nested exception is:
java.net.ConnectException: Connection refused
the problem is in the line with //!!!!
If I comment this line out, it works fine.
The purpose of this line to invoke check_server is to
have a check first.
Who can give me some hints?
Thanks much!

I have been bitten by this copy-paste error a few times too. I find that two
things work really well for me to avoid it:
- Define variables in as narrow scope as possible. For instance, I have
often found that most of my GUI elements only need to be referenced during
construction, not during normal operation when all the listeners are set up,
so most of my buttons, menus, lists, tables, etc, are defined as final
method variables, where different parts of the GUI is constructed in
different methods. In extreme cases (like in test code) I have even break
long methods into a list of scopes to ensure that variables are not "reused"
without initialization by accident.
- If I copy more than a one or two lines, I stop and think if perhaps it
would be better to refactor the otherwise copied code into a new method.
Regards,

- Arrays.asList() doesn't work quite like I would think it shouldI've included an example of the problem I've run into. I'm trying to
randomize an array of integers, much like the following program does.
Unfortunately when I ask the system to do so, I don't get a randomized
array. Now normally this wouldn't bother me. I would just assume that
a new object is being created and then destroyed by the garbage collector
without my ever seeing it, but in this case it looks like a bug.
Isn't the whole point of the asList() interface to allow this kind of
thing?
Is this a bug in Java?

- Jet Version 4.0 is outJET is an AOT (Ahead Of Time) optimising compiler. I use it for nearly
everything I run on my own machines. Excelsior came out with Jet
Version 4 today.
This marks some big changes precipitated with a new legal agreement
with Sun. Some of the changes are good, some distressing.
See
http://www.excelsior-usa.com/jetlatest.html?ml=jet400
The good news your compiled apps no longer need a Sun JRE installed.
The bad news is you can no longer distribute self-contained
executables. You must distribute the ENTIRE JRE in compiled DLL form
along with your app!! Phht! Why Sun insists on that makes no sense to
me. I can see them demanding no stripped down JRE, but what difference
does it make if proprietary complied equivalents are stripped down?
The other good news in the compiler now meets Sun's validation suite
for compatibility. I never had troubles with compatibility, but is
nice know that is nailed even better.
Pricing is in flux. My website entry is a bit out of date at
http://mindprod.com/jgloss/jet.html I will be updating it in the next
few days with information they sent me.
The big advantage of Jet over java.exe is apps start up a lot faster
and I can start them with a simple exe name. It makes my apps easier
to use as command line utilities.
The biggest disadvantage of Jet is you must exactly match DLL with
app. You can't run old code on a new DLL runtime without a recompile.
So roughly you convert every app and every customer at once to the new
compiler version. Keeping old compiled code around creates headaches.

- architecture for gui status bar messagesHi,
I have an app (Java not that is too pertinent) which is a fat client
GUI with a main form, numerous dialogs, wizards, menu actions, toolbar
functionality etc.
I am looking for a consolidated method for reporting errors. I already
have code to log the exception, warning, error etc to a local circular
file.
But I also wish to display an error message to the end user to indicate
a problem occurred.
I can't stand a popup error message.
Rather I would like to do something similar to Internet Explorers
active x warning message, where a bar subtly rolls up with a warning
icon allowing you to click for further information.
While I do throw Exceptions up and up as far as I can - there are many
places, such as within a custom control where I trap the exception
early.
So to get the interaction with the main frame (or a dialog) should I
really pass JFrame or JDialog references throughout my code - or should
I use the good old global variables...ew...
thanks

- Cannot start Eclipse on HPUX system - UI HangsHi,
I am trying to run Eclipse 3.1.1 on an HPUX machine (uname -a = B.
11.11, 9000/800 which I assume means I am running OS 11 on an HPUX
9000 machine) and I am using a 1.4 JVM. When I start Eclipse it hangs
on any window/wizard/dialog box that requires input. For example if I
start Eclipse with no parameters, the workspace window appears where I
choose my workspace directory. I cannot input any data or selct OK, or
anything. I am stuck there and need to kill everything.
If I run Eclipse with the -d option then it goes to the normal Eclipse
start window. Everything looks fine, but again I cannot select
anything, click on anything or use any menu. Also, the progress bar
that shows up while starting never quite finishes. There do not seem
to be any logs created that I can find.
I am running Cygwin from my laptop to connect to the remote HP Machine
and I am using ssh -Y to start the window/session.
Is there any trick to getting Eclipse to work on an HPUX machine?
Thanks

- Creating a Private Key from byte arrayHi,
I have a 256 byte array in my code which I have to use a key in a
MD5withRSA hash.
As far as I can tell, in order to use the MD5withRSA algorithm I need
to use the Singature object.
In order to initiate the Signature object, I need a PrivateKey object.
How do I instantiate a PrivateKey object using my byte array?
I have only managed to create a SecretKey object with my byte array,
but the Signature requires a PrivateKey. I can not cast a SecretKey to
a PrivateKey...
What is the easiest way to create and initialze a new PrivateKey?
Thanks,

- date problems.......hi,
I'm trying to write a little program to send myself email reminders at a
date in the future... I wrote a little interface in which I send the
date, body of e-mail.. etc...
problem is date being set is exactly one month into the future from when
I set it.. if I say, for example, send me e-mail on Dec. 12, when I
print out date I sent in form, it prints Jan 12, 2007... to wit:
process info sent with request:
sDate = getParameter("date");
mDate = Integer.parseInt(sDate);
sMonth = getParameter("month");
month = Integer.parseInt(sMonth);
sYear = getParameter("year");
year = Integer.parseInt(sYear);
set date based on info sent with request:
Calendar calDate = Calendar.getInstance();
out.println("calDate: " + calDate + "<br><br>");
// this prints confusing stuff.. can't make out exactly
// what date this returns...
calDate.set(Calendar.YEAR, year);
out.println("year: " + year + "<br>");
// (prints what I expect..)
calDate.set(Calendar.MONTH, month);
out.println("month: " + month + "<br>");
// (ditto..)
calDate.set(Calendar.DATE, mDate);
out.println("date: " + mDate + "<br><br><br>");
// (ditto..)

- Who Says What Your Fashion Statement Is?Who exactly should say what your Fashion Statement is? You of course!
Each of us has our own likes, dislikes comfort zones, body shape &
size, and life styles. Yes its wonderful to pick up the magazine that
shows this years top stars like Sarah, Jessica, Nicole, and Gwen but
hey we aren't them right.
Perhaps my comfort zone is a loose fit, maybe yours is a very tailored
or tight fit. I like turtle necks, you've got cleavage and like to
show it. Maybe your a rancher and functional is important, or an
office executive where a professional look is critical. Tweeds in and
you hate tweed, then don't buy tweed. Hot colors are in but your skin
is washed out, then stick to the colors that look good on you but
perhaps dress them up with a little color. Low rise pants are in but
they aren't attractive on you, then don't buy them.
It's all wonderful and dandy for the fashion world to tell us what is
in, what we should wear. But the bottom line is clothes that we buy
and hang in the closet never to be warn are a waste of our money.
Don't feel pressured to stay with the trends. Trends come and go. If
you stick with your basics and then add a piece here and there that
fits the current fashions you'll be much better off.
So pick up the popular fashion magazines like Vogue, Style, or Elle.
Have a flip through. Then take what you like and use it and toss the
rest away. What really matters is that you feel "good" in the look you
present. When you feel good about how you look your confidence level
jumps, your happier, and your positive energy flows around you.
If a pair of blue jeans with a tank top and big bold earrings is your
thing then that's your fashion statement. If you like long skirts,
heels, and gold jewelry then that's your fashion statement. Don't let
anyone or anybody change you from who you are. Because you

- Weird behavior on allocation...what's going on?Greetings,
I'm working on an application which will be very math-intensive, and
requires the use of mathematical constructs known as quaternions.
They are basically 4-vectors and that's all you need to know for this
discussion.
Here is the offending code snippet in the main():
Quaternion q1 = new Quaternion(5.0, 7.0, 6.6, -8.0);
q1.print();
Quaternion q2 = new Quaternion(-4.0, -3.0, 2.0, 1.0);
System.out.println("q1 and q2");
q1.print();
q2.print();
Quaternion q3 = new Quaternion();
System.out.println("q3 before multiplication");
q3.print();
q3 = Quaternion.mul(q1, q2);
System.out.println("q3 after multiplication");
q3.print();
Here is the output I get:
quaternion: 5.000 + 7.000i + 6.600j - 8.000k
q1 and q2
quaternion: -4.000 - 3.000i + 2.000j + 1.000k
quaternion: -4.000 - 3.000i + 2.000j + 1.000k
q3 before multiplication
quaternion: 0.000 + 0.000i + 0.000j + 0.000k
q3 after multiplication
quaternion: 0.000 + 0.000i + 0.000j + 0.000k
Can anyone explain to me what I'm missing? I'm assuming that by doing
new, I get two separate instances, init'd as shown, so that q1 and q2
are not the same thing. FYI, most of the code in the Quaternion class
is static, so I'm guessing it has to do with some subtle but insidious
misuse of the static keyword in my class definition. Please help!
Thanks.

- Oracle TopLink + composite mappingHello,
I have a little problem with Toplink:
I have a table in Oracle DB:
table T1 {A: integer, B: integer, C: integer}.
I want to have following mapping:
class X { int A; intB;}
class Y{ X objct; int C}
so the objct (of class X) is a composite of class Y, and both of
objects (composite and owner) are in the same table.
Is it possible to make such a mapping in TopLink?
Thanks for every helpful answer.
