I think that there is much more framework to support secure sockets (like for

That does not really "dock" the internal frame... it just makes it imobile.  I

Re: Re[2]: Can Java Catch Signals ?

[Jason Dillon]

I ran into a rather annoying problem with this library.  Perhaps someone else
could confirm the same problem. I wrote a rather large distributed threaded
network management system.  When the system was started up lots of log messages
were sent via tcp to a logging server, and the rest of the system was
functioning fine.  After I added the very simple code to catch SIGTERM and
SIGINT, the system logged only a few messages and proceeded to hang.  After
removing the code to initialize the signalListener the system once again worked
as designed.

I played a bit with the jni library, but ended up not using it do to the
problem above.  I thought that the jvm was using signals in some way to handle
something, but I did not look into it any more.

If anyone has any ideas on why this may be occurring or if the jvm indeed does
use signals in some odd way please let me know.

Modal JInternalFrame?

[Jason Dillon]

Does anyone know how to get an JInternalFrame to be modal via JDesktopPane?  I
have looked at the jdk docs, and there is a bit of babble about it in
JOptionPane, but no matter what I try I can not get a JInternalFrame to become
modal.

I looked into showing the glass pane, then adding the frame to it, but that
does not work very well either.  The frame shows up for a quick second, then
vanishes.  Even if that did work, it is quite a pain to show that glass all of
the time.  Did they (swing developers) think that no one was ever going to want
a modal internal frame?

I am trying to avoid using external frames so I can better manage the overall
user experience, but it seems there is no easy way to create a modal dialog in
this fashion.

If you or someone you know has had any experience with this problem PLEASE let
me know.  I am going quite mad, quite quickly over this apparent lack of feature
in swing.

This is not really a modal internal frame... it just appears on top of others.
There is nothing to prevent users from mucking with other windows.

I will read the containers bit as you suggest... but I still don't know how to

Swing menu problem

[Jason Dillon]

I have noticed that with all of the blackdown jdk's, swing menus don't line up
correctly until the main frame has been moved or resized first.  I checked with
the java-liunx bug tracking software and found that this bug (#61) is listed in
the 'done' section with a comment of:

This problem has been fixed in V3 but technically the bug is in the Swing java
files in Swing Utilities

It seems to still be occuring.  I have never seen this work correctly with out
having to move the parent frame/dialog/window first.  I ran the same code on a
solaris box (displaying to my computer) using the same swing.jar and the code
executed correctly.

Is it possible that this has not be fixed yet?

Re: Swing menu problem

[Jason Dillon]

I stand corrected.  I don't know what I was thinking exactly.  I tried this
again with v4a and it works fine.  I guess it has been one of those days.  My
apologies for any headaches I may have caused.  Thanks you Juergen for
catching my mistake.

Unfortunately I am still having Socket problems with v4a (in code that I did not
write), so I am doomed be annoyed by the older jdk's broken menus until there
is a fix for the current version.

Linux JIT?

[Jason Dillon]

Is there any other JIT compiler for Linux other than TYA?  I have been using
TYA for a while.  I have found that it does not really help for swing
applications, rather it hinders.  I was using NetBeans with TYA and it was
quite slow to react to ui events.  It was also eating about 30% of my p2
constantly at idle.  Without TYA the ui reacts much, much faster and eats 30% of
my p2 spuratically at idle.

I was wondering if there is anything else out there... or if anyone might know
how to optimize TYA so that I can get better performance out of it.

JDesktopPane & moveToFront

[Jason Dillon]

Hey, this really isn't a Linux related question, but I am going nutz trying to
get newly added JInternalFrames to move to the front of a JDesktopPane (at the
DEFAULT_LAYER) and receive focus.

I have tried

_desktop.add (frame);
_desktop.moveToFront (frame);

&

_desktop.add (frame);
frame.moveToFront ();

... I could go on and on, but the end result is that the new frame always ends
up behind every thing else.  I can't seem to find the right combination of
methods to achieve the proper result... and I was hoping (desperately... ok well
not really so desperately) that one of you might know the trick.

RedHat 4.2 is based on libc v5.x so jdk_1.1.6-v5-x86-lib5.tar.gz is just what

RE: help!!!

[Jason Dillon]

Try setting your classpath to contain jdk116/lib/classes.zip:

sh:

CLASSPATH=/where/ever/you/put/it/jdk116/lib/classes.zip
export CLASSPATH

csh:

setenv CLASSPATH /where/ever/you/put/it/jdk116/lib/classes.zip

You should also set JAVA_HOME to /where/ever/you/put/it/jdk116/ in the same
fashion.  That should fix it.  Let me know if it doesn't.

RE: Retrieving a fully qualified hostname under NT

[Jason Dillon]

Under Linux I don't get the FQDN for my machine.  Primarily because when I set
the machine up i did not specify it's hostname as its FQDN (which I don't think
it should be).  Java should have better access to the local machine's various
names, but then again Java should have lots of better things.

If you get this one figured out please let me know.

Re: Retrieving a fully qualified hostname under NT

[Jason Dillon]

You should not have too, but if you want FQDN, then it looks like this might be
the best way.  Otherwise you will have to jump throgh lots of hoops to check if
the value the jvm returns is really a FQDN.

canonical domain name

[Jason Dillon]

Is there any way to get the canonical domain name for localhost?  The machine
that I am working on only returns the short domain name (node name).  If the
machine I am on is named 'lust' and its domain is 'mpath.com' I want to get
'lust.mpath.com' back.

This is the code that I was using to try and get a host name:

String localaddr = java.net.InetAddress.getLocalHost().getHostAddress(); 
System.out.println (java.net.InetAddress.getByName (localaddr));

If anyone knows how to do this it would be a big help if you could let me know.

Document Writing Tool

Hey there... this does not really have any direct relationship to either of

tool.  I need to get some higher level docs written up so that I don't have to
answer a billion questions every day.  Before I have just written up some plain
html via emacs, but I find that it is very hard to maintain... and well as I
said it's quite plain.

Maximum Heap Size

[Jason Dillon]

Is there any way to get the maximum heap size from inside java.  I though that
Runtime.totalMemory() would return that, but it does not.  I current am running
one vm with -mx50m and totalMemory() is returning 5242872, which is about 5mb
not 50mb... unless I am totally crazy.

I am running into a problem where my vm grows too big, to fast (faster than the
consumers of the collected data can consume it), resulting in a
OutOfMemoryError in all running threads.  I changed the vm to run with -mx50m
and it ran for much longer (about 5 days) then it too did the same thing.

Currently I am trying to add some sort of alert before it runs out of memory,
mostly for debugging purposes, but it seems like the set of methods to access
memory do not take into account the maximum limits passed in via -mx.  I can
see that this is a good thing, because I could tell it that it has some insane
amount of memory when it really has a few megs... but is there a happy medium?


If anyone has run into memory problems and found suitable solutions I would
like to hear about them.

True Emacs (XEmacs) was not necessarily designed to be an IDE, though it can
be used as one... which means that it is and IDE (and a whole lot more).  Some
people can handle using Emacs as an IDE.  I personally just use Emacs as an
editor... not an IDE, mail reader or web browser... though I could.

I think that NetBeans is going to be a great IDE once the speed issue is dealt
with.  I used it for a while, and despite the fact that I could not use Emacs
with it (I hope they fix that someday), it was very easy to use and helped me
get some prototypes up and running very quickly.

Perhaps when TowerJ supports AWT/Swing so I can compile a native binary, then
NetBeans will not be too slow to use.  It would be nice if there was some
generic platform independent (and free) IDE out there somewhere, with the power
of Emacs that could be easily modified to fit anyones needs... but I have not
found such a splendid product yet.  Perhaps I should just write one... too bad
Java is so slow or I would.

native synchronized methods

[Jason Dillon]

This is not really java-linux specific, but this is the only java related group
that I am subscribed to.  I am wondering if a native method is specified as
synchronized if the jvm will perform the proper MontiorEnter & MonitorExit
calls or if I should call them in the native method.

So for example... does:

native public synchronized byte[] getBytes ();

imply:

JNIEXPORT jbyteArray JNICALL Java___getBytes
  (JNIEnv *env, jobject jthis)
{
(*env)->MonitorEnter(env, jthis);
/* do something */
(*env)->MonitorExit(env, jthis);

return /* some jbyteArray */;
}

Re: native synchronized methods

[Jason Dillon]

Does this apply to native methods as well?  The docs do not really mention
anything about native methods (not in that section anyways).  I am wondering if
it is safe to assume that marking a native method as synchronized will
automagicly protect the object from access by other threads or if I have to
explicitly protect the method in the native code.

Re: will there be a jdk 2.x??

[Jason Dillon]

I think it is just a myth that they are working on 1.2... soon it will turn
into legend.  ;P

setEnabled()

[Jason Dillon]

Do any of you know if setEnabled() on a swing component is supposed to notify
all of its children that it is disabled?  I thought that is was supposed to...
but I can't seem to get it to work.

rmic is way slow

[Jason Dillon]

I am running into a real bottleneck when compiling rmi applications
with: java_dyn full version "Linux_JDK_1.1.6_v2".  rmic takes forever to run on
a single class.  At first I thought it was just a jdk 1.x problem, but when
running sun's 1.1.6 rmic finishes in about 1/30th the time that Linux does.

Does anyone know if there is a way to speed up rmic on Linux?
