Deploying BIRT in Weblogic 8.1

jyol2005

I have searched the forums for this issue and didn't find any with the same description. So, here it goes.

I'm trying to deploy my application in WebLogic 8.1 and I have copied the jars from ReportEngine/lib to WEB-INF/lib and platform (configuration+plugins) directory to WEB-INF. My source for initializing the ReportEngine is as follows:

config.setBIRTHome(servletContext.getRealPath( "/WEB-INF" ));
IPlatformContext context = new PlatformFileContext();

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

The above code is in a separate class (BirtEngine - which is found on this site for one of the examples) and from my servlet's init() method, I invoke BirtEngine.initBirtConfig(). When this point is reached I get the following exception:

Am I missing something in terms of deploying it under WebLogic 8.1?

Please help.

Thanks.
