Building RPM's with Java alternatives
by Kenneth Porter
I have the Sun JDK installed on FC2 using the -compat package from JPackage
and I'm trying to rebuild the new subversion-1.3.0-2 SRPM. I get a bunch of
compile errors for the javahl subpackage from what appear to be header
incompatibilities. Has anyone tried this?
(I had to patch the subversion spec file to use the more generic link to
the JDK and to set the BuildRequires to the generic JDK-compat Provides
instead of the gcj-specific one.)
I'll reply back to this thread as I learn more, with more details about
exactly what is happening. I just wanted to see if anyone else has tried
substituting the Sun JDK for gcj and run into something similar.

For today we backed out the LD_PRELOAD fix.
This isn't what we want for FC5, but we had to make some decision
today, and this was simplest and let builds work on the s390.

Thanks Hans.
Andrew, could you please try this patched SRPM with the x86-64 Eclipse
to see if it fixes the problem?

Proper way to add user-access to cdrom?
by Dan Thurman
Hi Folks,
What is the proper way to enable selected users access
to the CDROM, especially if they log in remotely. I use
VNC to remote login to my linux box all the time when I
am even in the same room.
I can get access to the CDROM as root user via VNC
but I dont want to do that.
I added myself as a user to the 'disk' group file, but that
does not seem to be the trick.
Any pointers?
Kind regards,
Dan

RSSOwl
by Anthony Green
Here's an RSSOwl 1.2 SRPM (and itext dependency SRPM) suitable for
submission to FE:
http://people.redhat.com/green/FE/devel/
This is based on the work that Robin Green and Andrew Overholt did.
I modified itext to not encode images in JPEG (since we don't support
that yet), and rssowl was modified to use standard JCE classes instead
of the bundled BlowfishJ.jar. I also had to tweak the SWT code a little
to work with the version we ship.
It seems to work well for me (with my pr13212.so hack). It would be
nice if others could try it before I go through the submission process.
Thanks,
AG

Problem with find command in rebuild-gcj-db.in
by David Walluck
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
$ find --version
GNU find version 4.2.27
Features enabled: D_TYPE O_NOFOLLOW(enabled) LEAF_OPTIMISATION
find seems to want find -L and not find ... -follow
Looking at the manpage, these options are slightly different. I didn't

RSSOwl, SWT, and table sorting
by Pete Zaitcev
Hi, Anthony,
I have a question for you. What does happen if you click into column
headers to sort them? When I use the SWT from RSSOwl CVS, the sort
indicator in the table headers disappears. Ben Pasero says it's a bug
in SWT. I sent him a patch (attached), but he's not taking it.
So, I'd like to know if it's the same with your SWT.
Greetings,

avalon-framework and doclet classes
by Anthony Green
Gary -
I was trying to build something recently that required
org.apache.avalon.framework.logger.Log4JLogger from avalon-framework.
The avalon-framework.jar file in FC4 appears to be missing this class.
I grabbed the SRPM file from rawhide and attempted to build that
instead. The build failed with this...
[javadoc] java.lang.ClassNotFoundException: com.sun.tools.doclets.standard.Standard not found in gnu.gcj.runtime.SystemClassLoader{urls=[file:./,file:./], parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}
I've seen this before. It seems that our com-sun-javadoc or
com-sun-tools-doclets-Taglet jar should be on the default classpath
somehow.
In any case, I noticed that this build of the jar file includes the
proper class, but as far as I can tell, this is the same SRPM that was
used in FC4. Why wouldn't the FC4 jar file contain the Log4JLogger
class?
Thanks!

64-bit java code
by Anthony Green
On x86-64 systems we're building all the java bits as 64-bit. Has
anybody looked at whether or not this is a good idea (vs 32-bit), or is
it just done that way by default?
