error.CannotStartupOSGIPlatform

Hi, 
 
I'm trying to use BIRT 4.2 in a web application that runs on JBoss AS 5. 
 
I am using report engine API for report generation. 
 
The problem is that it only works one time (For the first time the report is generating fine). The next time when I try to render a report I get an exception on: 
 
Code: [Select all] [Show/ hide]Platform.startup(engineConfig); 
 
With the exception: 
 
Config is EngineConfig: org.eclipse.birt.report.engine.api.EngineConfig.emitterConfigs={html=org.eclipse.birt.report.engine.api.HTMLEmitterConfig@12fe3bb};

PFA the engine file? Is their any issue with engine file? 
 
i'm definitely sure that the ReportEngine/lib jars were in my WEB-INF/lib folder..except org.apache.xerces, org.apache.resolver and org.apache.serializer 
 
Anyone have any idea of why this happens and how to solve it? 
Thanks in advance!

Try adding this to your code after shutting down the platform.

RegistryProviderFactory.releaseDefault();
