Hi Ben,
thanks for your response, but I am still struggling ith all these
classpath-issues on jboss.
Is there anybody here, having experience with deploying RAP-applications
on Jboss and is using EJB3 Jax-WS Webservices? It would be great, if you
could explain your deployment structure.
Here is mine (for the RAP-part):
In the Eclipse-Environment I am using four Bundles:
A) The RAP-Application
B) custom-rap extensions / helper classes. shouldn't matter here.
C) data. All EJB3 Remote-Interfaces and classes used on both, client
(RAP) and server
D) jboss. A dummy-bundle containing all the JBoss-libs and exporting all
available packages
When starting in Eclipse, this is running fine.
In bundle C, I needed to add a Require-Bundle directive to bundle D.
Only requiring the packages exporting from D resulted in an error, since
obviously JBoss masks some java-classes with own implementations (For
example javax.xml.ws.spi.Provider). These jboss-classes were not
resolved when only adding the Required-Packages directive, but with the
required bundle, it works.
So I decided to make the required bundle optional, and added a
"DynamicImport-Package: *" to the manifest of package C, hoping it would
resolve the packages from the JBoss-ClassLoader at runtime.
But to no avail.
Before I go on explaining my situation, let me first ask, my assumption
is correct:
* Only the data-package need direct reference to the jboss-libs, because
it's the only bundle using them?
But when deploying the application as a war in JBoss 5.1 , it seems like
the dependencies cannot be resolved.
Is there any way to debug the classloading in OSGi? Like have any chance
to see for bundle X these are the theoretically available packages?
getPackages in the Equinox console does not really help.
It seems as OSGi running in a war in JBoss does not incorporate the
JBoss-classpath.
For example, when running a plain war in JBoss, the ClassLoader
Hierarchy looks like this:
Hierarchy of Thread.currentThread().getContextClassLoader():
Original class loader in Remote client is
org.jboss.web.tomcat.service.WebCtxLoader$ENCLoader
Parent of: org.jboss.web.tomcat.service.WebCtxLoader$ENCLoader is
org.jboss.classloader.spi.base.BaseClassLoader
Parent of: org.jboss.classloader.spi.base.BaseClassLoader is null
SystemClassLoader is sun.misc.Launcher$AppClassLoader
But when dumping the same in the RAP Application it looks like this:
Hierarchy of Thread.currentThread().getContextClassLoader():
Original class loader in Remote client is
org.eclipse.core.runtime.internal.adaptor.ContextFinder
Parent of: org.eclipse.core.runtime.internal.adaptor.ContextFinder is
sun.misc.Launcher$AppClassLoader
Parent of: sun.misc.Launcher$AppClassLoader is
sun.misc.Launcher$ExtClassLoader
SystemClassLoader is sun.misc.Launcher$AppClassLoader
Hierarchy of getClass.getClassLoader:
Parent of: org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader is
sun.misc.Launcher$AppClassLoader
Parent of: sun.misc.Launcher$AppClassLoader is
sun.misc.Launcher$ExtClassLoader
What makes me wonder is, that there isn't
org.jboss.classloader.spi.base.BaseClassLoader in the
ClassLoaderHierarchy in OSGi.
Is there somebody here, who can help me with my dilemma?
I am really getting desperate now.
Thanks,
Philipp
