- Help - Emulator package for clientsHi,
I need to a put together a simple J2ME all-inclusive emulator package
that a non-technical client can extract and run.
I was able to do this with the old Sprint WTK (v2.0) by just including
the appdb, lib and bin subdirectories with the jad & jar files nested
in the bin folder.
But, I'm no longer able to get this to work now that I've upraded to
Sprint WTK 3.0
Can someone suggest another emulator that allows you to neatly package
an archive for a non-technical client?
This is to present a game primarly developed for Sprint handsets.
Thanks,
Jeremy

This method getCookies() returns Cookie[] but I can't understand which
cookie does it contens
Only those which refers to the server or all clients cookies ?

- canonical or absolute path?Although the Java SDK documentation defines "absolute" and "canonical"
paths, the practical meaning is not clear to me. For example, if I want my
application to save a list of "recent files", which should I use?

- Mysteriously appearing Timer thread does not allow JVM to dieHi All,
In my application, a "Timer-1" thread seems to appear out of nowhere
and it does not let the application to shut down. This thread belongs
to a ThreadGroup that I create within the application and it starts
while another thread of the same ThreadGroup is executing. I am able to
pinpoint to fixed block of code during the execution of which, this
thread appears.
I did like to know if there is a way I can track and find out where
this thread is starting from ?
thanks in advance,
Chandresh

- Question for WebObjects programmers
I am in the process of trying to create a new newsgroup specifically for
the discussion of WebObjects, and I since I have seen some WebObjects talk
in this newsgroup, I would like to get some feedback on this.
Foremost, is there any interest in a WebObjects-specific newsgroup? Since
it is a Java-only platform now, can it/should it just be left for
discussion in comp.lang.java.* newsgroups?
Another question is are there any other newsgroups where WebObjects
discussion happens? It seems to me that most discussion currently happens
in Apple's and The Omni Group's mailing lists.
If there was a WebObjects newsgroup, what do you envision it being?
If anyone could give me some feedback so I can polish up my submissions
to news.groups, I would appreciate it.

- byte arrays fun...I am using data compression java.util.zip package. My problem is I
need to do it repeatedly, as in the code below, and am working on very
large strings. What is the proper way to "nullify" or realease the
memory that can be freed after using the byte arrays? Does setting
them to null actually cause that memory (heap? stack?) to be freed? I
am running out of memory and think this is where it is happening.
Thanks so much for any help...
Inflater i = new Inflater ();
i.setInput ( bufferWork );
byte[] decompressedBuffer = new byte[ maxCountersSize +
increaseSize ];
long decompressedReturn = i.inflate ( decompressedBuffer );
if ( i.getTotalOut () > maxCountersSize ) {
maxCountersSize = i.getTotalOut ();
}
String uncompressedString = new String ( decompressedBuffer,
i.getTotalOut () );
i.end ();
then to clean up
decompressedBuffer = null;

if there is no greedy approach how to prove it...

- threads/84778: libpthread busy loop/hang with Java when handling signals and Runtime.execThis is still happening on FreeBSD 6.0-STABLE as of 12/6/2005.
World and kernel were compiled without any CPUTYPE or CFLAGS options, as
was Java.
This problem is trivial to reproduce. One merely has to start httpd.sh in
Resin 3.0 with no arguments, wait for the JVM to start running, and hit
^Z or ^C.
The process then goes into an infinite loop in kse_release. truss -p
shows the following:
kse_release(0x8056f44) = 0 (0x0)
kse_release(0x8056f44) = 0 (0x0)
kse_release(0x8056f4c) = 0 (0x0)
kse_release(0x8056f44) = 0 (0x0)
kse_release(0x8056f44) = 0 (0x0)
kse_release(0x8056f4c) = 0 (0x0)
ktrace shows a bit more detail of the infinite loop:

Note that the valid-looking portion of the stack trace still isn't valid
higher than pthread_create(), though this could have still been a result
of the process still making calls while gcore was running, since the
process does not respond to the STOP signal.
I'm inclined to suspect that this is a Java bug, considering the smashed
stack.

- JDWP JNI AGENT_ERROR_NO_JNI_ENV MustangFolks,
I'm trying to use Mustang (1.6.0-beta2-b86) and Eclipse 3.2
I'm running a little test application, an ordinary "Java Application"
project.
Intermittently, perhaps once out of 5 or 10 times, after the program
runs,
and after a System.println that it executes as the last statement in
the
main() routine, I get the following in the Eclipse console window in
red
(i.e., it was presumably written to System.err):
ERROR: JDWP Unable to get JNI 1.2 environment, jvm->GetEnv() return
code = -2
JDWP exit error AGENT_ERROR_NO_JNI_ENV(183):
[../../../src/share/back/util.c:820]
Can't find anything about this anywhere. Anybody have any ideas?

java-programmer >> objection?
Sorry but I can not agree with that. If correctly used Swing is not
slow.
We are making complex softwares with Swing and almost none of our
customers complains about the slowness of these softwares. You can
find a lot of tutorials in Internet about what to do and how to
improve your Swing implementation. Often you have to change how your
data model works so that your software works quickly.

- Accessing a method inside of an object that is stored in a vector...I have been trying to post to .help all day but nothing is going
through. Will try it here and hope it does....
I am trying to access a getData() method that simply returns a stored
integer value from an object that is stored in a vector. I have tried
to do this but cannot get the notation correct. I tried google groups
and the only thing I got from there was to pull the object from the
vector into a temperary object. That didnt work.
So, here is the code I have so far of making the temp object and
making sure it is actually pulling one out. I still connot figure out
how to access the getData() method.
Any hints are appreciated.
import java.util.Vector;
public class StackUser
{
public static void main(String argv[])
{
Vector vector = new Vector();
for (int i = 0; i < 100; i++)
vector.add(i, new StackNode());
System.out.println(vector.get(0));
Object tobj = vector.get(0);
System.out.println(tobj);
}
}
public class StackNode
{
private int value = 0;
public StackNode()
{
value = (int)(Math.random());
}
public int getData()
{
return value;
}
}

- chaning fonts *only* w/ SynthHey all,
I want the same interface appearance I have now, which is the Metal
LaF, but I just want to make the fonts different. Same style, smaller
fonts. I installed Synth and have the following XML defined ...
<synth>
<style id="default">
<font name="Helvetica" size="10"/>
</style>
<bind style="default" type="region" key=".*"/>
</synth>
If I understand this correctly, doesn't this make the font size
Helvetica 10 (globally using .*) as default, and the rest of the LaF
should stay the same style, right?
The problem is, this makes the default fonts correct all over my
application, but the rest of the GUI is completely ... styleless. Is
there anyway for my menus, buttons, etc... to stay as is using the
Metal LaF, yet change *only* the font size?
Any help much appreciated.

- dynamic file download with *long* response time - How to show "Save As" early?I've got a Java servlet that delivers large database resultsets
transformed to Excel with the HSSF library. In some cases it takes
more than 15 minutes before transformation is done and content can be
delivered to the browser.
I want to show the "Save As" dialog as early as possible so the user
knows he's not lost and forgotten.
I already tried to send the response headers immediately after
receiving the request including content disposition and filename. Even
though the browser receives those headers it just won't trigger the
"Save As" dialog. This applies to both MS IE and Mozilla.
Any ideas appreciated.

- JUnit RemoteTestRunner ErrorHi. I was running a test suite under JUnit version 3.7.0 through
XDE/Eclipse version 2.0.1 and I got a null pointer error. When I
stepped through the program, I saw that the error occurs right when I
get a window telling me
that "org.eclipse.jdt.runner.RemoteTestRunner" type cannot be found.
Do I need this type? It does not seem to be in the junit.jar file.
Thanks for any info,
Ken

- Detecting compiler version at runtimeThis is a multipart message in MIME format.
Does anyone know if there is a way to determine which version of the
compiler was used. That is, at runtime - using 1.4.x - finding
out if the class/jar was compiled with 1.3.x?
Thanks

- [OT] Any way to see if a website is up in an automated way?I am looking for a tool or technique that can automatically check to see if
a specific website is up - say twice a day - and then send me an email if it
isn't. I do not want to have to manually check myself.
Does anyone know of a way to do this?
I have no money to spend on this so if there is no free service that does
it, I'd be interested in how I can program this, preferably in Java. I
assume that my best bet would be Java application that I could schedule via
Windows XP scheduler but I can code applets and servlets too if that makes
more sense.

- Java applets and client-side ssl certificates?Applet Gurus,
Is anybody out there doing Java applets and client-side ssl certificates?
When I turn the requirement on in Apache, I get handshake failure errors
when the applet tries to load. Certificates are installed in the web
browser for the user's html browsing.
Some of our customers are on locked down machines that don't allow
"installation of software" but they jave jre 1.4.2 and Java Web Start.
Considering using Java Network Launch Protocol (JNLP) or some other kind
of applet based install but I think this would require a signed applet.
This, in turn, would require a certificate to be installed beforehand
(to validate the signed jar). Since our certs are all done in-house,
I'm in a chicken/egg situation. All certificates are issued by an
internal CA but are not easy to get for various reasons.
Is there an easy way to mass-install certificates (to keystores) in a
secure way without touching all the workstations?
The applet/client-side certificates present four problems as I see it:
1 handling the user's certificate securely
2 Maintainig the internal CA and root certs
3 Excessive prompting for multiple passwords to keystores
4 Keystore security (Bouncy Castle libs are 1MB)
Does anyone have any advice to give?
Thanks

- poi hssf getCellStyle problemhey there,
i have a big problem with those cellstyles. i want to add background
color to some cells, but apparently i just can "change" cell styles
from cells which already "have one".
for better understanding of my problem, here's the code:
for ( int i = 0; i <= rowcount; i++ ) {
for (int j = 0; j <= colcount; j++) {
HSSFRow row = s1.getRow((short)i);
if (row != null) {
HSSFCell cell = row.getCell((short)j);
if (cell != null) {
HSSFCellStyle style = cell.getCellStyle();
style.setFont(font);
style.setWrapText(true);
style.setFillForegroundColor(colorIndex);
if ( (j%4== 0) && (colorIndex ==
HSSFColor.LIGHT_CORNFLOWER_BLUE.index) ) {
colorIndex = HSSFColor.LEMON_CHIFFON.index;
}
else if ( (j%4== 0) && (colorIndex ==
HSSFColor.LEMON_CHIFFON.index) ) {
colorIndex =
HSSFColor.LIGHT_CORNFLOWER_BLUE.index;
}
}
}
}
}
}
this piece of code just works for cells, which already have attributes
in their cell styles like background color and border. cells which
just have a border and no color won't get the instructed color...
does anybody know what to do? is the method cell.getCellStyle() not
the best option in this case?
best regards and thx in advance,
manuela
