Hi,
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.
Yes, i agree (of course). I will do that eventually, but currently the
main focus is to get a prototype running and ear's don't have nice
hooks that enable you to shutdown properly (well, not yet in ejb 3.0
that is...).
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.
Yes, that is clear. What surprised me is that some classes were found
(org.apache.felix.framework.Felix), but others were not (org/apache/
felix/framework/FilterImpl), while they are in the same package and in
the same archive, and the (loading of the) second is triggered by the
first. I checked the Felix source, and there is no special
classloading going on right there, it's just "new FilterImpl(...)",
which - in my (limited) understanding of classloading means that the
FilterImpl class is loaded by the same class that loaded the calling
class ("Felix"), right?
I can image JBoss doing "smart" things when an ear (classloader) is
discarded, but than i'd expect problems only when switching from one
classloader to another....
I was just hoping that someone could give me a clue, why such errors
(can) occur, but well, don't bother too much, we'll fix the shutdown
issue shortly i guess...
Thanks anyway.
Regards,
Peter

Follow up:
When i shutdown the framework before undeploy, it works fine.
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
