- tomcat - web service in a warHello I have the following problem. Normally when creating a JSP
application I put all files in a web archive (.war file) which makes it
possible to transfer the app to the webapps dir of another server and
the app is deployed directly by the application manager.
Also in the folder /axis/WEB-INF/classes I already have some
precompiled web services, which are running perfectly.
My question is, is there also a default way for creating .war file of a
web service (and related files) in such a way that I can put the .war
file in the axis dir on another server, and everything is going to work
directly (auto-deployment in axis dir?)

- Applet Security (File Transfer) QuestionsI've looked through a few books and various web sites. I'm still not clear
on this and would like to make sure I have this right.
I would like to use an applet in a web page. When the user presses an
"UPLOAD" button, a file chooser would appear, the user could select a file,
then the applet would read the file in and (instead of a regular upload),
e-mail it to a specific address (a program will be reading the emailed
files and processing them).
I think I read that as long as the user specified a specific filename (like
with a file chooser) and I converted the filename to a URL, I could read
that file without having a signed applet. Is this true? Can I read in a
specific file from an applet and e-mail it somewhere?
And, if I can't, it looks like it is really easy to sign an applet. Is it
as easy to create a signed class as it looks? If I upgrade the applet, do
I have to have it re-signed or done over so the new version is recognized
too?
Thanks!

- In Search Of: Abstract Algebra system.I'd like to use an abstract algebra engine of some sort to define 3d
shapes and their intersections.
For example, I would like to create a structure for a Sphere that is
represented by (P - P0) dot (P - P0) <= R0*R0
where R0 and P0 are constants.
And the intersections of two Spheres, is represented by a system of
inequalities:
[(P - P0) dot (P - P0) <= R0*R0,
(P - P1) dot (P - P1) <= R1*R1]
I'd also like to be able to determine the intersection points of the
surface of this system with a Ray.
The actual goal is to create a Beam Casting project in Java. Beam
Casting is like Ray Casting, but you start with a pyramid instead of a ray.
I've found a library called Java Algebra System 2.0, but I'm confused on
how to apply it toward my goal. If there is anything more specifically
tailored to my problem, or someone can help me understand JAS, I'd
greatly appreciate the info.
Thanks,
Daniel.

- ATI or NVidia - best for Java3d?I'm contemplating purchasing a new graphics
card, and would like to purchase one that
performs well with Java3D.
Which begs two questions:
1. Which moderately high end card is
better: ATI, or Nvidia? Given the current
controversy relating to Half Life 2 and these two
cards, I'm frankly a tad unsure!
2. Is there a well-known benchmark written in Java3d
to make the card choice a little easier?
Many thanks in advance!

Only for enums.
You can, of course, create your own Collection (Set, List, Map) of instances
of any non-enum class. There is a more-or-less standard idiom for that,
called a "registry".
public class RegisteredInstance
{
private static final Map <String, RegisteredInstance> registry =
new ConcurrentHashMap <String, RegisteredInstance> ();
private final String name;
public RegisteredInstance( String n )
{
if ( n == null )
{
throw new IllegalArgumentException( new NullPointerException(
"name is null" ));
}
name = n;
registry.put( name, this );
}
// add @Overrides for equals(), hashCode()
// add other logic, including registry access
}
If you don't need associative lookup of the instances, you could use a Set or
a List for the registry instead, and iterate at need.

- log4j as a static class ?Hello all,
every example I found for log4j tells you to declare a final static
variable to hold the reference to log4j Logger for each of your classes
-by means of Logger.getLogger(Myclass.class)
What about my approach?
package mypackage;
import org.apache.log4j.Logger;
public final class Log {
public static org.apache.log4j.Logger log =
Logger.getLogger(Log.class);
private Log(){
}
}
Then, from within any class I need to log something, I simply call
Log.log.myloglevel("something");
Is this wrong?
Thanks,
regards

- Transparency in Java ImagingHi all!
When I have multiple images in Java (I'm using JAI, but I thing this has
to do with ColorModel, which is present in AWT) which I want to stack
above each other, is there any possibility to define white as
"transparent", i.e. whenever an image contains white pixels they should
not be drawn... any ideas?
If this is impossible, how else do I use transparency when drawing
images? (i.e. how can I stack them, without each overwriting the image
below it)?
thanks in advance and kind regards,
Messi

- Switching GTK theme on Java 1.6 (i.e., mustang)I'm at a loss on how to change on-the-fly the theme (i.e., resource) for the
GTK look and feel on Java 1.6 (Mustang). On 1.5 it was a simple matter of
setting a system property (i.e., "swing.gtkthemefile") like this:
System.setProperty ("swing.gtkthemefile", fGTKThemeFile);
But on Mustang it has been completely changed.
It is probably just as easy but I'm missing something?
Thanks.

My statement was true. That you can extend it to absurd lengths by pretending
it is a mathematical claim and then find it lacking because it is not is a
problem for you, not for me.

Cool cool video, matrix-like, about Java Everywhere.

The REALLY funny thing is it's in Flash version 8, which just goes to
show Java may be everywhere, but there are degrees of everywhere even
in this.

- -Xms setting makes IE exitFolks,
My company uses a Java based server application, and Internet Explorer
on our client machines. Recently our server application was upgraded,
and instead of needing Microsoft's JVM on the client machines we are
now using Sun Java version 1.4.2_08.
Performance around applet caching was poor, and the recommended cure
for that was to set "-Xms128m -Xmx256m" in the Java Runtime
Parameters from the Java control panel. On machines that have never had
the Microsoft JVM installed this fixed the problem.
However, on machines that have had the JVM installed, this causes the
browser to exit whenever an applet is started. From doing some research
it seems this problem is usually caused by a conflict between the Sun
and Microsoft Java components. So the JVM was uninstalled using the
process detailed here: -
http://www.java.com/en/download/help/uninstall_msvm.xml#cli
(That is identical to the steps found on Microsoft's knowledgebase)
After a lot of experimentation I have found that setting only the
starting memory setting "-Xms64m" does not cause any problems.
However this is clearly far from ideal and I am looking for a better
solution. Does anybody have any suggestions?

- Client Code for Axis - Newbie QuestionHi,
I'm a first time Axis 1.1 user and trying to figure out how to write
web services client code. I used WSDL2JAVA to create java source from
the wsdl. I ended up with the following files...
xxxx_Port.java
xxxx_Service.java
xxxx_ServiceLocator.java
xxxxBindingStub.java
xxxxRequest.java
xxxxResponse.java
Does anyone have some sample code they can share with me that shows
the basics of how to set up the request and response parameters and
then actually make the call to the web service. Not sure which
classes or methods to use.
Thanks

using Access :) ) or missing someting?

- Networked version of Swing (X windows style)?Hello,
I was wondering if something like that exists or if someone has ever
thought about it:
Instead of Swing updating the local screen and obtaining events from
the local mouse & keyboard, it may be useful in some cases to have a
networked version of Swing, just like XWindows.
Imagine a workstation connecting to a remote JVM that starts a typical
swing application. But this JVM/Classpath/etc is configured so that all
Swing calls are serialized to the remote workstation, where all the
screen updates are made. And viceversa for the mouse and keyboard.
Probably Swing is not well designed for this kind of "pluggability"...
in any case it would be an interesting thing to have.
The key requirement here is that preexisting AWT/Swing applications can
be remotely executed without modification.
Is there any project or product that does this?
If not, any ideas on how to implement it?
Thanks,
Luis.

- Strange problem with Bluetooth and RFCOMMHi,
I have programmed an application that sends data from a PC to a mobile
phone. This application uses the Bluecove library and a RFCOMM
connection.
When I establish a connection between these two devices and send from
the server (PC) a float number (e.g. 3.12) to the client (mobile
phone), the number is displayed correctly and everything is fine. But
when I want to send 20 float values the following reaches the phone:
3.12
3.12
3.12
3.1199999,
-2.12422343E14
9.707659E-27
9.707659E-27
...
0.0
0.0
...
0.0
These values are changing when sending them multiple times. Sometimes
there are more correct numbers (3.12), sometimes less. And sometimes
the mobile application just crashes without an error.
Probably the reason for that is the data which is not transferred
properly. I tested different ways to transfer the data, e.g. partioning
the data into smaller packets or using DataOutputStream but nothing was
a success.
Snippets of one of my source codes:
/* SERVER */
OutputStream out = null;
ByteArrayOutputStream baos = new ByteArrayOutputStream();
DataOutputStream dos = new DataOutputStream(baos);
for (int i = 0; i < 20; i++) {
float f = 3.12f;
dos.writeFloat(f);
}
byte[] rawData = baos.toByteArray();
dos.close();
baos.close();
out = connection.openOutputStream();
out.write(rawData.length >> 8);
out.write(rawData.length & 0xff);
out.write(rawData);
out.flush();
out.close();
connection.close();
/*CLIENT*/
in = connection.openInputStream();
int length = in.read() << 8;
length |= in.read();
byte[] data = new byte[length];
length = 0;
while (length != data.length) {
int n = in.read(data, length, data.length - length);
if (n == -1) {
throw new IOException("Can't read data");
}
length += n;
}
ByteArrayInputStream bais = new ByteArrayInputStream(data);
DataInputStream dis = new DataInputStream(bais);
for (int i = 0; i < 20; i++) {
Log.out(dis.readFloat() + " ");
}
Has anyone an idea how to solve this problem?

- [signed applet] certification authorityHi,
I have a signed applet (signed myself with jarsigner.exe).
It works fine but the users get a warning message before accepting the
applet to execute.
Next step, is to have my certificate trusted by Verisign or other
third party.
Do you know any link to a site that would explain the procedure to
follow in details ?
Which certification authority would you recommend ? the cheapest ?

extended tutorial, the highlights of this upgrade are support for Java
WebStart, extended support for distributed development through an
include mechanism and dependency tracking across multiple test-suites.
An evaluation version is freely available for download at
http://www.qfs.de/en/qftestJUI/download.html
where you'll also find a link to the latest release notes.
What is it?
===========
Based on capture/replay, but extending far beyond, qftestJUI manages
the creation and execution of automated tests for Java/Swing
applications with a graphical user interface. It runs on Windows and
all major Unix systems with JDKs from 1.1.8 to 1.4.2.
The key feature of qftestJUI is an exceptionally high test
reusability, minimizing the effort necessary for regression testing.
Intuitive graphical design of tests reduces the cost of introducing
qftestJUI into the QA process. Additionally, qftestJUI sports a set of
features for the advanced user such as variables, procedures and
scripting. Extensive documentation, including a tutorial, is available
for users approaching the product with different background and skill
levels.

- Add a computer language to NetbeansHello
This may be a simple question. I searched in Google but I think I am
using inapropiate words for the query and I don't get what I want.
How can I add a syntax highlight for a new language, in my case X3D,
to Netbeans?
Any general tutorial?
Thanks
Jordi
Note: Does someone already have done this with VRML or X3D?

- Designing presentation-tier for occasionally connected applications.Folks
We are in the process of developing a web-based app that needs to be
functional when the user is on the road where the Internet connection
to the server is not available. There are 3 basic requirements:
1. Must be web-based, not a fat client app.
2. The UI for the offline mode and on-line should be identical.
3. In the off-line mode some basic functionality to enter data (fill
forms) should be available, that do not need to be reentered when the
connectivity is available.
Can some one think of a solution on how one would design this app. To
me disconnect from the network mean no web application, but some one
here insisted that we can put a web-server/appserver on each client
machine (about 200 of these).
Swing based solutions are ruled out because that is not a web-based
architecture.
Any ideas?
Thanks in advance.

- Bypassing Struts validator - why doesn't bCancel=true work?Hi there,
I'm trying to bypass the Struts validator sometimes on my page. I'm
using JSP and Struts 1.1.
Basically I have a submit button that submits a form. The Struts
validator component is working great for client-side validation of the
contents of this form.
However, now I've been asked to implement a drop down on the page that
repopulates another drop down box when it is changed. Because of the
size of the data, I'm doing this server side, not client side. That
is, I want the page to refresh and then repopulate these fields.
This means I have to bypass the validator to ignore anything the user
might have already entered in the fields. I've read all over the
newsgroups how putting "bCancel=true" in your onclick or onchange
method should do the trick, but it doesn't work for me. When I create
my select box like this
<html:select property="countyId" tabindex="1"
onchange="bCancel=true;document.forms[0].method.value='changeCounty';document.forms[0].target
= '_self';document.forms[0].onsubmit();document.forms[0].submit();">
and then change the drop down box, nothing happens. Control never
gets to my changeCounty action. I've checked that. But I also don't
get any validation messages from the validator, despite there being
validation errors on the page when I change the drop down box. So
it's like the validator function doesn't execute either. (The method
value is there because I'm using a DispatchAction class.)
Is the validation function running or not? How can I bypass the
validation and still submit the form?
Thanks for the help!

i've been offered a job which involves getting a large content based
java application based on ATG dynamo server version 4.5.0, they
considering a move to a j2ee enviorment system (a rewrite of the
entire application is in order) and need a person who will study the
current application and who willl provide insight for writing the
existing one.
i have no actuall expirience in j2ee ejb etc.. and as such, would

- Log4j - dealing with multithreaded invocations?Hi,
I have a class with 4 methods. I want to use Log4j to log messages for
each of these methods to a common log file.
Ideally I would like the log messages for each method to be seperated
from the others. But if multiple users were to invoke the methods at
the same time, then the messages in my log file would be jumbled up
with the others.
I can probably try making the methods synchronized so i dont get into
this sort of trouble, but logging by itself doesn't seem to be a good
enough reason to be making methods synchronized.
What approach can I use to deal with this?
Thank you,
Rohit.

- Tools To Tackle New Code Base?Hi,
I'm looking for advice on how to quickly come to grips with
a large ( ~5000 files), undocumented codebase that's mostly Java
( compiles with Sun's command line compiler under Windows XP ).
Here are some considerations.
1) I'm new to Java, coming from a C++ background
2) I need to get a handle on this quickly but also cheaply.
3) I have no access to the original programmer.
What tools are availble that might help me analyze and
visualize the relationship between various modules and classes
in this project? In the past, with large C++ codebases I've
looked at Doxygen but the learning curve seemed very steep
and I never did figure out the graphical tools.
Appreciate any advice, the more concrete the better.
If there's a different forum I should be posting this in please let
me know.
TIA,
Gerry Murphy

- XApool +multiple replicated nodesHi All,
I am creating a small research system for testing various fall over
algorithms in a distributed database situation and and have been looking at
using XApool as a possible JDBC XA proxying and load balancing solution. I
am just wondering if anyone else has had any luck getting the XApool system
to talk to different oracle hosts ? I plan to use the development/personal
edition of oracle and their thin jdbc driver, which is also XA compatible.
Anyway, if someone could point me in the right direction I would be much
appreciated :) I've had a look at the docs but cannot see where I add the
different nodes into the pool ???
