Hello,
When I launch the framework within Eclipse, I am able to start my
bundles properly. However, once I run osgi using the bridge servlet, I
start having trouble. I was able to deploy a simple servlet on tomcat,
with the help of people in this news group, but I am having trouble
adding dependencies. I repeatedly get NoClassDefFoundError exception on
one of my own bundle classes. My intuition and investigation suggests
that one of the other bundle that my bundle depends on is not loaded
properly. What bothers me is that I can start sample.http, which
depends on these bundles, and I can get the status to show as active.
However, I get the ProxyServlet Not Found error in the browser, which I
am guessing is due to the missing bundles.
Our plugins make extensive use of the Eclipse's core plug-ins,
including but not limited to UI plug-ins. The servlet does not need to
use any of the UI plug-ins, but it has dependencies on plug-ins that
depend on the UI-plugins. I went through and started as many bundles as
I could once the osgi prompt came up, but I am still unable to load
several bundles.
1) Am I allowed to use Eclipse's UI plug-ins in my osgi framework?
2) Is there a standard way to do this? Currently, we have features
that define the list of plugins that we need from Eclipse. I added the
features into our features folder (WEB-INF/platform/features), and I
added an includes feature tag in the
org.eclipse.equinox.servlet.bridge.feature_1.0.0. I also exported the
feature from within eclipse and added all the jar files to our
WEB-INF/platform/plugins folder. Does this sound okay?
3) When I start the framework within Eclipse, I am able to load all my
bundles. However, things are messed up within tomcat. Is there a
remote debugging feature that will let me debug the deployment within
tomcat? I need more fine grained debugging than what SS is giving me
right now.
Here is the result of SS:

Hi Khawaja,
The servlet bridge is meant to support server-side development whereas it
looks to me like you're trying to run an RCP app -- Maestro.
I suppose there's no real reason why you couldn't however it's not designed
or tested using UI elements like SWT or the eclipse.ui plugins.
That said... there's work (RAP, RSP-UI) that might allow re-use of these in
the future.
One thing I'd like to clarify is that the servletbridge and (sample.http)
does not require the whole org.eclipse.core.runtime or any of the UI
plugins -- just the requirements as specified in their manifests (e.g. an
OSGi framework (e.g. org.eclipse.osgi) and the OSGi Http Service). To start
integrating you should try to make your install smaller and then gradually
bring in components ensuring they resolve and start correctly.
For remote debugging in Tomcat you can use JPDA e.g. /bin/jpda.bat and the
excellent remote debug support provided by the Eclipse IDE.
The specific problem you bring up about update.configurator not being
started is because you have two instances present and it's a singleton (e.g.
"there can be only one" resolved).
