Description praneeth botta CLA 2013-04-26 12:01:51 EDT 
I have created birt engine in an application say it as App1, it was running successfully. Now when i am trying to create another birt engine in another application say it as App2. Birt is failing to generate report.

These both applications are installed in WAS7 server. They are located in the jvm and server.

Application Running order:
Scenario 1: App1->App2->App1 = App1 birt is failing
Scenario 2: App2->App1->App2 = App2 birt is failing

The bellow are the logs from birt:

I have created birt engine through the below code:

EngineConfig config = new EngineConfig();

RegistryProviderFactory.releaseDefault();

Platform.startup( config );
IReportEngineFactory factory = (IReportEngineFactory) Platform.createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY );
birtEngine = factory.createReportEngine( config );
