ServerException unmarshalling : unknown protocol felix (RMI and ExtensionManager?)
Hello,
I have a problem in a remote call by RMI of an EJB in JOnAS with Felix, which
involves as far as I can say the ExtensionManager. I think I could solve my
problem by disabling the "addURLToURLClassLoader" call in its static
initialization block, but I did not find any "public" way to do it
(configuration, arguments, etc.)
The error I get is "<code>java.io.IOException: unknown protocol: felix</code>"
The stack trace is below

This happens when I try to invoke a service by its name "indexFinder" through
the Carol RMI client of ObjectWeb. I am no expert in RMI, nor do I have
control on the server's classpath, so I have limited options.
Is there anyone who faced the problem and found a way around it ? I would
welcome any explanation too on what's happening in RMI (how the server's
unmarshalling method is aware of the "felix" URL in my client's JVM ?)
I use an embedded Felix (1.0.3), in Sun's JRE 1.4.2, with the following config
map :
<pre>
FelixConstants.LOG_LEVEL_PROP, "4"
FelixConstants.EMBEDDED_EXECUTION_PROP, "true"
FelixConstants.SERVICE_URLHANDLERS_PROP, "false" <-- I hoped that could help
me, but this does not appears to be so
Constants.FRAMEWORK_SYSTEMPACKAGES, "org.osgi.framework; version=1.3.0,
org.osgi.service.packageadmin; version=1.2.0, org.osgi.service.startlevel;
version=1.0.0, org.osgi.service.url; version=1.0.0, org.osgi.util.tracker;
version=1.3.2"
BundleCache.CACHE_PROFILE_DIR_PROP, MYCACHEDIR
</pre>
I am of course available for further questions, but please note that I reside in
France so there could be a 6 to 8 hours delay between your message and my reply.

Yes. the server doesn't use felix. I have also raised the issue at JIRA.

I assume the exception is happening on the server which doesn't use
felix, right?

Hi,
Is there a way to disable the extension manager or a solution?
i am facing similar exception as the topic starter, when retrieving workitem
from openwfe via rmi.
The client application is using felix 1.2. Tried equinox without problem.
Below is the stack trace.

james

You are right, there is no public way to disable the extensionmanager
(perhaps there should be). Could you try to enable the URLHandlers
service and/or try to use the latest trunk version of felix (i.e.,
1.1.0-SNAPSHOT)? That might fix your issue. If not please let us know
then I add a way to disable the extension manager.

Karl
