java on linux

[Corwin Light-Willians]

Hey, I'd like to help out with the project. What can I do?

Re: Compilation weirdness

[akaul]

This seems to be a problem of the compiler not being able to determine
that the variable has been initialized.

I remember having a problem on a Win JDK - (pre 1.1.5)
If  you declared a variable without initializing it & later initialized
it in some if-else statment - it used to crib giving errors about
un-initialized errors.

Thanks.

JDK 1.1.6v4a problem

[Joe Carter]

I having problems seeing text in textfields and
I get lots of the following...

Warning: 
Name: textfield
Class: XmTextField
Character 'l' not supported in font.  Discarded.

I didn't get this 1.1.6
I've tried the older font.properties but that made
no difference.

I'm using 1.1.6v4a on a RH5.0 (with most of the current patches)

Clues anyone?

(I'll submit a bug when I'm sure it's not me doing something dumb!)

Thanks for the information. I have my jdk1.1.6v4a running under RedHat4.2
The library libXp is in XFree86-libs-3_3_3-2-1_i386.rpm.

Since I couldn't install ld.so.1.9.9 I kept my 1.9.5 but removed libc.so.5
and libdl.so.1 from $JAVA_HOME/lib/i686/green_threads/ as indicated by Paul
Ho and my jdk worked.

One problem though. Since I installed XFree86 3.3.2 (I installed all the
updates) my X server won't start as a regular user (I can start it as root).

When I run X as a regular user I get:

xf86OpenConsole: Server must be running with root permissions.
You should be using Xwrapper to start the server or xdm.

Where to find Xwrapper or what is wrong?

Grendel is a mail/news client, written in Java.

Grendel was a part of the 1997 effort to rewrite Navigator/Communicator
from scratch in Java.  That project (code named ``Xena,'' but sometimes
referred to by the press as ``Javagator'') was cancelled before
completion.  

Nobody is actively maintaining Grendel, and it needs a lot of work
before it will be usable.  But there it is.  Perhaps you'd like to give
it a caring home?

For details, see http://www.mozilla.org/projects/grendel/

That makes Grendel the third incomplete mail client we've released the
source to this year!  (Actually, that's not quite true -- we've now
released the incomplete source code to one mail client, and the source
code to two incomplete mail clients -- but who's counting.)

Xwrapper is in the main XFree86 package.  You need to install all of the
XFree86*-3.3.2 rpms as there were some security concerns that were
addressed, iirc.  You'll then want to make /etc/X11/X a symlink to your
actual X server (/usr/X11R6/bin/XF86_SVGA) and make /usr/X11R6/bin/X a
symlink to /etc/X11/X.  Conversely, you could just make /usr/X11R6/bin/X a
symlink to your server but I believe there are reasons (fsstnd related)
for using the former method.

ddd, gdb, jdb and java: debuging on linux

[Luiz Otavio L. Zorzella]

Hi,

I've been missing a good debuger for java on linux for quite some
time. It was then that I found this on the ddd
(http://www.cs.tu-bs.de/softech/ddd/) manual, under "News":

**

- JDB support.  DDD now also supports JDB as inferior debugger.  All
  important JDB features are available via the GUI.

- Java support.  Requires GDB 4.17 or later (or JDB, of course).  All
  data display features are available in Java.

**

Well, I went nuts, 'cause ddd is the cream of the crop, I personally
think... And I went to try it for myself. After guessing a lot
(couldn't find a straight documentation on ddd for this), I found that
a "ddd --jdb &" does the first trick (i.e. to use jdb as back end for
ddd).

It's somewhat cumbersome, as you have to restart things every time
your program exits (and starting jdb takes quite some time), but the
worst is: I could not display any variable... It tells me my variable
is not valid in that context. But I could do breakpoints, "steps" and
"nexts", etc...

Well, now I could not figure out how to do the second trick
(i.e. debug java with gdb). I have gdb 4.17, but I couldn't find a way
to use it to debug a java program.

Did any of you folks have success on this?

Thanks a lot!

I don't know if it is "good" but the IBM Alphaworks debugger known
as JIKES DEBUGGER works rather well (IMHO) for most JAVA programs.
It is written in 100% "pure" Java so it runs if you Java can do AWT
correctly.  The nice thing is that it comes with source code too.

Check out the Alphaworks web site at http://www.alphaworks.ibm.com/formula

(I have modified the source to have line numbers in the listing window.
Check out the diffs I posted to the JIKES DEBUGGER discussion list)

And, yes, it shows variables and objects and threads and...

If I try to install the main XFree86 package (XFree86-3_3_2-1_i386.rpm) I
get a message saying:

pam > 0.59 is needed

But I only find a pam 0.59 for glibc (Redhat 5.0). If I try to install this
I get:

failed dependancies:
libnsl.so.1
libcrypt.so.1
libc.so.6
ld-linux.si.2

You need to setuid the X server to root.  Or, you need to get a copy of
Xwrapper, which can be found at the Xfree86 ftp site. 
(ftp://ftp.xfree86.org)  I'm not sure of the exact location, but you
should be able to find it there.  If not, drop me a line and I'll do
some checking for it.  Its easier than figuring out which rpm to 
download.

You *can* distribute the JRE.  That's exactly what you need.

Ok, I talked to Mike Wangsmo at RedHat and it looks as though there are
problems with the updates directory.  He said that this problem was
corrected over a month ago and that it should be straightened out in a day
or so.  Sorry for the inconvenience.
