Re: go back to gzip!

[Volker Augustin]

Ok, there has been a long discussion about using bzip2 or not. Apart from personal 
problems using 
bzip2 (I have only access to a Win95 machine and bzip2 --help does display help, but 
since it's 
going to stderr you cannot read all of it and since I could not find documentation I 
have no clue 
how to use bzip2) I would recommend that you provide both a bzip2 and a gzip-version 
of the 
distribution. Isn't that a fabulous idea? Why didn't anyone else come up with it? It's 
the obvious 
thing to do, isn't it? It solves all problems - well maybe not all, since e.g. I've 
been trying to 
work effektively on Win95 for a long time now without result... :-)

Given that there are a few good windowing toolkit out now for linux (GTK,
QT, JX) could the JDK be proted to these instead of useing mofit?

HotJava needs a permissions file.  It's reported to kind of work when
you create the permissions file.

I believe the classpath project is working on a gtk based set of peers
that can be used as a drop-in replacement for the current motif ones
(though they aren't finished yet).

Library?

[Pepijn Schmitz]

OK, I realize that this must have been asked a million times, but
nevertheless it't not in the README or the FAQ: where do I find the
libstdc++ library that the JDK 1.2 needs to run on my Red Hat 5.2
system? Whenever I try to run anything I get:

Exception in thread "main" java.lang.UnsatisfiedLinkError:
/usr/local/jdk1.2/jre/lib/i386/libfontmanager.so:
libstdc++-libc6.0-1.so.2: cannot open shared object file: No such file
or directory

I'd prefer a precompiled binary, but if someone could point me to the
relevant sources I'd be very happy too!

Ciao!

Excuse me, but all people *I* know (personally) have bzip2 as part of their 
Linux distribution. And even the kernel will be compressed with this program in 
the near future. IMHO bzip2 will replace gzip soon just because it allow 
for even denser compression than the old compression utility.

Dimitris, 
there is a good chance to run JDK1.2 with TYA1.3 plugged in 
next time, but currently I am fighting against some bugs and I 
consider current TYA as in pre-beta status.

I can't promise that it'l be faster - rather slower. OTOH if TYA 
could not compete with sunwjit, it's IMHO important to have a JIT
that's GPLed and FREE and so good for educational purpose.

BTW I've decided NOT to sign any kind of sun source code license,
so next TYA1.3 will not yet use any special features JDK1.2 offers 
for JITs - simply because that's completely undocumented stuff.

Cheers

Process priority all mucked up

[Helge Wilker]

Hi,

for a few days now, I have noticed that java and javac processes running
on my linux box get re-niced to very low priorities all the time, down to 
16 or 20.  This makes big compiles vey slow.  I am not aware
(obviously) of any changes I made that could affect this.  I am also
not too sure whether this only affects Java or other executables also.
The behaviour appears with kernels 2.0.34 and 2.0.36.

Anyway, if somebody thinks this sounds familiar, I'd be happy to hear
about your experiences with this!  If this is a non-Java problem, I'd
also be happy to be shoved in the right direction instead of simply
being flamed  :)

Thanks,
Helge

Hi,

I've noticed that some processes initiated with Runtime.exec() on NT never
terminate, ie, process.waitFor() never returns.  Of course, it worked
flawlessly on Linux.  (Thanks porting team!  You rock!)

> Huh?  NT is one of the best Java platforms around.

Hahahaha that's a good one.  One of the apps I'm working on crashes
with Dr.Watsons within 20 minutes.

Hehehehe like a rhinocerous on a unicycle :)

Relative to what?

I switched from NT to Linux for Java development and have found it much better.
Our project has advanced much more quickly after the change than before. We do
get Jikes for fast compiling and excellent JVM's. I use Visual Slickedit on
Windows and Linux and also CVS on both. I used to use Kawa on Windows but find
that a better editor with some project features is better than the IDE with good
project features but a poor editor. I prefer not to use a GUI builder.

Amusingly enough most of my deployment is on Win 95 currently.

Re: This works on Linux/ W95 not on NT. Why?

[Rachit Siamwalla]

This talk has made me wonder. I always had problems running my Java
Swing gui-intensive apps on non-Windows platforms. When the application
is under "stress" ie. when clicking and draging and moving the mouse a
lot, I have had java lock up on me all the time (main event loop just
freezes). The deadlock seems to be within the native event handling
code. This was with Linux and Solaris under JDK 1.1.6 / 1.1.7. I have
not tested this under JDK 1.2 yet. Did anyone else have this problem and
or (even better) have anyone had this problem and solved it? I remember
spending a week on this problem and getting nowhere (used thread /
monitor dumps, looked through event handling source, etc...). I tried
checking out dejanews, mailing newsgroups about the problem, but had no
answer.

Rachit,

We have not experienced this problem. We have experienced some platform
differences eg AltGr, Deadkey, Tab, Focus painting but not instability.

Are your apps using 3rd party libraries? Are the user interfaces built by
"hand" or using a GUI Builder?

I just wonder if using something like JBuilder creates applications that are as
easy to test cross-platform.

*.bz2

[Doug Robinson]

Hello
OK I admit it I a a newbie to Linux
(but not Unix) & I cannot find out how to
uncompress a *.bz2 file. 
I would not care except that the
1.2 source is in whatever that format is & the doc
shows the uncompress step using gunzip. A non-starter.

Help me please!

Our user interface is built by 95% hand (some minor dialog boxes are
built using symantec cafe). If noone has had the same problem it may be
the result of using some specific combination of components on my part
CardLayout + JLayeredPane) or because of a custom component (something
from scratch that extended from JComponent / JPanel) that we wrote.

Actually, I'm beginning to suspect CardLayout, because the way it is
implemented is horrid... (it uses setVisible() to switch between
panels). This causes problems when you do stuff with mouse listeners to
multiple panels within.. Drag + Drop does wierd things on it and
JTabbedPane I belive uses CardLayout, so that sucks.

But still again, whatever I do shouldn't lock up java in the native
code...

Re: Bzip2

[Jim Dovey]

Don't get me wrong, I'm glad to have java-linux even if I have to
download and install bzip2 to use it.  Still I think it's better
to stick with more commonly available installation tools (and libraries
and kernels for that matter).

Is java-linux for kernel developers (100s of people) or the linux masses
(millions)?
I suppose Debian includes it, but RedHat 5.2 does not include bzip2, nor
bzip2
capable tar.

--Tucker

Erm, yes it *is* on RedHat 5.2 Something like System/archiving with
Glint. It's definitely on the CD. I've got it. I watched it install the
other day. And a really good thing about bzip2? It compresses the JDK a
*lot*. I bunzip2'ed it and then gzipped it so's I could keep it stored
away and tar zxvf when I wanted to reinstall, but upon looking at the
file size, I found that it had gone up by (oh, I can't remember now...)
I think it was about 8-10Mb. A lot, anyway.

Huh?  NT is one of the best Java platforms around.  It's relatively stable, has
great JVM availability, has very stable JVMs, has a slew of IDEs and other
tools, has several very fast compilers

We do almost all development on NT for these reasons even though we typically
deploy on Solaris (for scalability and core OS reliability).

It's more likely to be a path issue of some kind.
