Question on starting Equinox from Java Application [message #100312]

Thu, 25 October 2007 03:33

Eclipse User

Hi all,

I've followed tutorial
http://www.eclipsezone.com/eclipse/forums/t93976.rhtml to enable me to
start Equinox programmatically (Thanks Alex). I have the following
questions :

1. One of my bundles (Jetty) needs a parameter that tells it to open at
the specified port. When I launch Equinox from Eclipse I only have to put
"-Dorg.osgi.service.http.port=8080" at the VM arguments section. How do I
pass the parameter through code ?
2. One of my bundles actually points to an Eclipse plugin project that's
not jarred yet. Since installBundle method apparently expects url that
points to jar files, how do I tell Equinox to install this bundle ?
3. Since starting this Equinox takes place on startup method of a TestCase
class, do I have to call each bundle's stop method on teardown method or
is just calling EclipseStarter.shutdown enough ?

Any help would be greatly appreciated.

Best Regards,

Setya

For question #2 I've tried the following code:

bundle = context.installBundle("reference:file:<path to my project>")

but then it throws ClassNotFoundException exception stating that it can
not find my activator class.

Any ideas ?

That would indicate that it installed correctly and found the Manifest fine
but it couldn't find your Activator's class.
I'd check your bundle classpath and double check the location of your class
files.
The other possibility is that you're getting a misleading CNF exception
because a dependency of your Activator is not being found. In that case I
would attach a debugger.

This is weird, I have no problem running it from PDE and all dependencies
are satisfied.

From the stacktrace it's clearly trying to load my bundle activator and
failed.

Hmm... if I had to guess.
Did you export your bundle?
When you run under PDE /bin is automagically added to your bundle-classpath.

Yes, you guess right.
After I add 'Bundle-ClassPath: bin/' in the MANIFEST.MF through PDE it
works as expected.

Thank you very much for your help.

I want to go deeper here. How to do above programmatically ?
