OSGI bundle problems when deploying server extension

Looking at the information you have provided I am curious why "com.ibm.team.workitem.common" is included twice in the feature.xml: Once in as an <import> element (inside the <requires> element) and once as a <plugin> element:

<import>

<plugin>

While this might not be the cause of the problem you are having, it is certainly the first thing to investigate.

Sadly, the <import> and <plugin> elements in my last post were stripped out. Let me try again. These are the duplicate elements for the com.ibm.team.workitem.common plug-in:

<import>

<plugin>

OK, so it appears that I cannot figure out how to include those XML elements. Let's try one more time.

<import>

<plugin>

(OK, the preview looks good.)

OK, I concede that posting XML to the forum just does not work, even after the preview says it will. Suffice to say, "com.ibm.team.workitem.common" appears twice in your feature.xml file.

Hi Simon,

Thanks for the reply.

I tried removing the duplicate entry from feature.xml, still am getting the same error.

Is there anything else we need to take care ?

Thanks,

Hi Simon,
Thanks for the reply.

I could resolve the issue, it was a version mismatch problem.
I was using RTC 2.0.2 in Tomcat environment and the WAS instance was running on RTC 2.0.

Now, I am facing another problem. I could install the plug-in and it shows status as "RESOLVED". However, its giving Class Cast exception in the logs. So I am not able to proceed.

Please find the error message below:

Can anybody suggest a solution for this?.

Hi,

I could resolve the error and install the plug-in without any error. The OSGI console says:

id State Bundle
150 ACTIVE example_1.0.0.1532

The plug-in is supposed to add one precondition, which will run some custom code while clicking on the 'save' button from the Web UI. I could achieve the same in RTC 2.0 running on Tomcat. Now I have deployed the same plug-in on RTC 2.0 running on WAS and its in 'ACTIVE' state.

However, I am not able to find the new precondition in the 'Process Configurations' tab of Project area, which should be listed in the preconditions list. Is there any thing I am missing here ?. I could see and add the new precondition in Tomcat where as its not showing in RTC running on WAS.

Please suggest me a solution for this ?

Thanks,
Satheesh

This sounds like

Clear you browser cache and reload the page. Also a restart of the
server once it has been provisioned should ensure it works as long as an
admin request was not use to trigger the provision

The stack trace is telling you that the class you have specified as the
BundleActivator, "advisor.example.WorkItemFailAdvisor" is invalid due to
a ClassCastException. My guess would be that it does not implement
org.osgi.framework.BundleActivator.

Hi Richard,

Thanks a lot for pointing out the issue.

I have implemented the org.osgi.framework.BundleActivator in my class and the error got resolved. Now the I can see the plug-in installed and ACTIVE without any error in the log.

Still I am not able find the new precondition added in the Project Area->Process Configuration-> Preconditions list. Once the plug-in is deployed it should be available in the list right ?. Because after deploying the plug-in, I could see the new precondition added, in Tomcat environment . However, its not happening in WAS environment. Both the servers are running the same version of RTC (RTC 2.0).

Is there any additional configuration required in WAS environment ?. Please guide me if I am missing something.

Thanks,
Satheesh
