WAR deployment on JBoss

[Andreas Held <hl...@bbp.ch>]

Hi

I am now trying to deploy the ServiceMix War to JBoss. The first few 
steps do work well, I can deploy the WAR and the JMX console shows the 
proper result.

In a second step I am trying to install the lwcontainer component. First 
I install the shared library 
servicemix-shared-3.0-incubating-SNAPSHOT.zip through the JMX console, 
which does indeed work. The next step, installing the archive 
servicemix-lwcontainer-3.0-incubating-SNAPSHOT-installer.zip fails 
miserably with the following exception:

2006-09-04 09:39:37,085 ERROR 
[org.apache.servicemix.jbi.framework.InstallationService] Deployment of 
Component failed

Obviously I am doing something wrong, but what could it be?

Re: WAR deployment on JBoss

I finally figured out the problem, it appears to be a classloader issue.
The problem seems to be that servicemix-jbi and servicemix-lwcontainer (or
whatever component)
are being loaded by different classloaders! My workaround was to remove
servicemix-jbi from the WAR
package. Alternatively, servicemix-lwcontainer can be added to the WAR
package. Whatever way, it is
important that the component to deploy and servicemix-jbi are loaded by the
same classloader.
It is not quite clear to me why this is so. Might there be a problem with
the used classloader that does not
properly delegate to its parents?

In any case, I can now deploy the WAR to JBoss and add other deployments
using the JMX console.

Regards

Andreas
