I may not totally understand the situation, but if shutting down Felix
properly resolves the issue, then it is clear you should be doing that.
It is always a good idea to properly shutdown the framework, otherwise
threads will possibly hang around and it won't ever get garbage collected.
Regarding the NCDFE, perhaps this is a JBoss thing were it disables the
class loader of its web apps after the are undeployed. The Felix
framework does not have any control over how its own classes are loaded,
they are usually set up for it on the application class loader or in
this case on the container class loader.

I would assume that JBoss discards the old classloader / creates a new
classloader when i redeploy the ear, especially since we use the
classloader-per-ear configuration (not the JBoss default).

Hi,
I'm running Felix (1.6.0) embedded in an ear that is deployed in JBoss. Was
quite easy, works like charm, compliments for you guys!
Now i'm running in an issue that i don't understand when i hot-deploy the
ear.
Here is the case.
When I autostart Felix with only the shell bundle and the remote shell
bundle, everything works fine. Hot deploy of the ear works without problem
(although i should add that during undeploy of the ear, felix is not
shutdown (shutted-down? shutdowned? ;-)), which for example leads to a
bindexception when the remote shell is started - but apart from that it
works fine).
But... When I autostart Felix with these bundles and the fileinstall
bundle, the hot deploy results in the following error (note that the initial
startup works fine):
java.lang.NoClassDefFoundError: org/apache/felix/framework/FilterImpl
at org.apache.felix.framework.Felix.addServiceListener(Felix.java:2434)
at
org.apache.felix.framework.BundleContextImpl.addServiceListener(BundleContextImpl.java:203)
at org.osgi.util.tracker.ServiceTracker.open(ServiceTracker.java:270)
at org.osgi.util.tracker.ServiceTracker.open(ServiceTracker.java:235)
at org.apache.felix.fileinstall.FileInstall.start(FileInstall.java:51)
And the same for the other two bundles, e.g.
java.lang.NoClassDefFoundError: org/apache/felix/framework/FilterImpl
at org.apache.felix.framework.Felix.addServiceListener(Felix.java:2434)
at
org.apache.felix.framework.BundleContextImpl.addServiceListener(BundleContextImpl.java:203)
at org.apache.felix.shell.impl.Activator.start(Activator.java:66)
I don't have a clue, something weird is happening here.
Maybe it is related to the fact that felix is not properly shutdown before
the redeploy? (i will try to test that scenario right away)
Any ideas?
Regards
Peter
