[2.3.0] Cannot start war system bundle
Hey guys, I've been playing with a stand-alone Karaf 2.3.0 for a few weeks to
figure out what OSGi is all about. I've had a lot of success with it until
recently while trying to deploy web archives. I've created a hello-world
wab with the appropriate manifest entries. I also have installed the war
system feature. When I attempt to deploy my wab, it fails to resolve the
'javax.servlet.ServletContextListener' dependency. I believe this is
because the war feature isn't actually running. Executing the osgi:list
does not show war as a running bundle. I can request it to start by running
'osgi:start war'; it asks me if I'm sure I want to start a system bundle to
which I reply with 'yes'... but nothing seems to happen after that.
Sometimes the prompt returns to me, sometimes it seems to just hang up. I
don't see the java process running hot or anything.
Does anyone have an idea what I may be doing incorrectly? Thanks in
advance,
Joe

I've decided to take a step back and approach this a little differently. I'm
not a fan of including my dependencies within the WAB; I was just hopeful
that would make it easier to get something working. Now I'm attempting to
deploy each dependency as a bundle. This of course entails the usual
challenge of "OSGi-ifying" several jars that aren't OSGi-ready. I'm using
BND to help me, but I'm open to anyone's input on how to best rectify
3rd-party libs for OSGi.
I don't doubt that I'm also compounding my complications by attempting this
"Hello World" with Scalatra, which is also new to me. Hopefully the issues
I'm hitting aren't directly related to that library.
Anyway, I've hit a strange class loading issue while deploying my WAB that I
hope one of you understands:
java.lang.NoClassDefFoundError: org/scalatra/servlet/ScalatraListener (wrong

Hi Joe,
those jars you import don't look good either. To much stuff that is
provided by the container already :)
The org.osgi.core-4.3.0.jar is definitely not needed there and I also would
recomend to import the slf4j stuff provided by pax-logging.
About your expectations, it does play very well :)
We take care about that and if you start with examples provided by the
documentation either of Karaf or Pax-Web you'll see that those
example or sample war and jar artifacts play nicely with Karaf.
Those samples of pax-web can be found at [1], all of those artifacts are
also available at maven central.
regards and merry Christmas :)

I'm using Karaf 2.3.0. Regardless of version, I would expect the system
modules in Karaf to play well together. Is it possible that I have
something misconfigured?
Thanks,
Joe

Hi Joe,
Karaf uses Geronimo *Specs*. So depending the Karaf version that you
use, you may have only Servlet Spec 2.5 available (not 3.0).

I was coming along well until I hit a ClassNotFoundException for a package
that I have as an import:
Caused by: java.lang.ClassNotFoundException:
javax.servlet.FilterRegistration not found by
org.apache.geronimo.specs.geronimo-servlet_2.5_spec
Is Geronimo something Karaf tries to use under the hood? I don't think it's
something I'm explicitly trying to use.

I sorta used BND and sorta hacked it. :)
Now I'm off finding out everything this WAB depends on. I wish that that
long list of libs were OSGi bundles themselves... would probably make it
easier to untangle.
Thanks!

One problem is that your Import-Package header is wrong. You should list packages, not classes. How did you get this manifest? If with bnd somehow can you show the instructions?
I'd expect you would need both javax.servlet and javax.servlet.http at least....

Hi Joe,
could you share your WAB MANIFEST, especially the Import-Package ?
war is feature, not a bundle: the war feature installs Pax Web bundles
in fact.
So better than osgi:list, you should do features:list -i to check if the
feature is correctly installed.
Regards
JB
