Security Exception

I'm using BIRT 3.7.0 ReportEngine API in java using tomcat as the EE server. But, when I want to view the report in HTML format I get the following exception:

org.eclipse.birt.report.engine.api.EngineException: Can't create data engine.

What am I missing? or where I'm going wrong.
