packaging lessons from FUDCon hackfest?
by Karsten Wade
Andrew Overholt and Tom Fitzsimmons sat with a guy from Alfresco (Lee
Faus) last Friday in the FUDCon hackfests. Mainly they were doing a
code review with him to see what he has to do to get Alfresco packaged
for Fedora. It was a great effort, and possibly enlightening for
everyone as to the scope of the problem ahead of us to get Java ISVs
packaged in Fedora.
Andrew, Tom -- where there any insights, lessons, ideas, or other
outfalls from that work with Lee?
Two specific areas of interest are:
* Tips, ideas, or plans for Java packaging ==> target
wiki/Packaging/Java
* ISV-specific lessons, tips, etc. ==> target wiki/SIGs/ISV
I'm asking on this list because I think a brain dump from both of you
here would give good exposure. I'm ready to glean content to make the
above wiki updates. :)

I think moving them to jpackage-utils would be sufficient, as it owns a
multitude of other java related directories right now. I have put this
down on my TODO list and will get to it on Monday (off today and
tomorrow).

Correct, technically they are not configuration related files. I'd be happy to
move them, but I am not sure what the best place for them is either :/ ..
suggestions are welcome. The files serve as configuration in the sense
that they provide maven with a "mapping" between where maven expects
jars to be, and where they actually are on the system.

The JARs are 99% application-specific so putting them into a
subdirectory makes sense to me and follows the guidelines we have in
place. We have no library forking or duplication of the dependent JARs,
either.

/usr/share/eclipse/* -> %{_libdir}/eclipse/
by Andrew Overholt
Hi,
In the past we've struggled with multilib issues in the Eclipse SDK
package. Examples include having to re-pack every JAR to have a common
timestamp, shuffling arch-specific JARs off to %{_libdir} thus causing
headaches with upstream mechanisms (which I'm concerned will continue
with the new version), etc.
I just found out today that Debian ships everything in
%{_libdir}/eclipse to avoid these issues. I'm proposing we do the same
for Fedora 10 and beyond.
Pros:
- self-contained installation like upstream
- dramatically speeds up builds
- remove potential for bugs with the multiple locations
- looks like an upstream download
- consistency with other distributions
Cons:
- larger disk footprint for multilib installations (on the order of 100
MB ... although the vast majority of users don't use both)
Does anyone have any thoughts on this?
Thanks,
Andrew

Eclipse plugins outside the Fedora effort
by Mat Booth
Hi all,
There's been question asked on one of my bugs[1] that I'm not
confident I know the answer to. Essentially, he's asking what the
policy is on using Eclipse plugins that are outside the Fedora effort.
I don't know of any formal documentation and my gut feeling is that
everything should just work, if you don't mind extra the configuration
because of the lack of really tight integration that comes with Fedora
packaged plugins. But I'm still new to Fedora as a contributor so I
though I'd garner a second opinion to make sure I'm not lying my arse
off.
Any thoughts?
Regards,
Mat

compatible provides?
by Benjamin Reed
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Would it be possible to add compatible provides to the openjdk -devel
package? Since OpenNMS uses Tomcat and/or Jetty, and does not
precompile it's JSP files, we require a JDK at runtime.
Unfortunately, there are no provides that are the same across OpenJDK
and Sun's Java:
Sun JDK:
[ranger@nen ~]$ rpm -q --provides jdk

jdk = 2000:1.5.0_15-fcs
jaxp_parser_impl

jdk = 2000:1.6.0_05-fcs
OpenJDK:
[ranger@localhost opennms-1.6]$ rpm -q --provides \
~ java-1.6.0-openjdk-devel
java-1.6.0-devel = 1:1.6.0.0
java-1.7.0-icedtea-devel = 0:1.7.0.0-0.999

ant possibly broken when using 'ant generate.wsdl' from axis2 examples
by Timothy Selivanow
Hi,
I'm going through the quickstart sample from axis2 and found an error
that only occurs while using the packaged ant in Fedora 8 and 9. Here
is the error I receive:
$ ant generate.wsdl
Buildfile: build.xml
compile.service:
generate.wsdl:
BUILD FAILED
/home/timothys/projects/lib/java/axis2-1.4/samples/quickstart/build.xml:53: java.lang.ExceptionInInitializerError
Total time: 0 seconds
When run with '-debug', I see *lots* of the following errors:
Caused by: org.apache.commons.logging.LogConfigurationException:
org.apache.commons.logging.LogConfigurationException:
org.apache.commons.logging.LogConfigurationException: Invalid class
loader hierarchy. You have more than one version of
'org.apache.commons.logging.Log' visible, which is not allowed.
When I use upstream's ant and set ANT_HOME to that, the error does not
occur and the build succeeds. I'm very new to java et al., so I don't
know if I am missing something, or if this is a bug in the way things
are packaged...
