Thanks to the great work of Andrew Haley from gcj, and other gcj
hackers, JOnAS has been known to work increasingly well on gcj. I've
decided to give it a try on Kaffe's pre2 release, and thanks to the help
of Florent Benoit from JOnAS and CAROL projects, I've managed to set
things up and get JOnAS to start up wth little tweaks here and there.
You'll need that latest JOnAS snapshot available from
after you extract the archive you'll need to change a few small things.
In file conf/carol.properties change carol.protocols to
Some of the other carol protocols try to use sun specific facilities
that do not exist on kaffe. The jeremie protocol works, though.
In file conf/jonas.properties, one needs to remove ear services from
jonas.services, since they do not work yet, due to an odd issue with jar
url connections. So one need to set jonas.services to
Since kaffe does not support java.endorsed.dirs, one needs to set
JAVA_OPTS environment variable to prepend the endorsed libraries on the
Since there seems to be an interestig bug somewhere either in kaffe or
in the class loading code that leads to lack of protection domains being
applied to some files, you need to apply the attached patch dali.diff to
Kaffe sources in ordr to make the accesscontrolcontext permit classes
with empty protection domains to read files. I have not investigated the
bug, so this is just a temporary workaround to let you fire up jonas
with the war files actually being loaded ;)
Finally, set JAVA_HOME to whereever you installed Kaffe from CVS head
with the attached patch applies, and from the jonas directory, run
After a little while, you should get the jonas startup success message,
and you should then be able to connect to the jonas instance at
localhost port 9000.
If you are using links, you can enter the admin console and make sure
that you are indeed running jonas on kaffe. then it looks a bit like
If you are using firefox, then the jonas console looks much prettier,
with cute whale graphics and all that:
I've also played a bit with ofbiz, but that looks like would be a harder
task to get set up properly. Anyway, if you are interested in running
J2EE servers on Kaffe, or another free runtime, this should get you
going. There are probably tons of bugs remaining, please report them to
the GNU Classpath bug tracker, if you can, and send your patches over
