[news.eclipse.newcomer] BIRT Report - Run time configuration files

[rameshp2006@xxxxxxxxx (ramesh)]

  We are facing problem in BIRT report engine. During the generation of 
BIRT report generation, TOMCAT will create BIRT runtime files / folders ,
org.eclipse.osgi/.manager/*
org.eclipse.core.runtime/.manager/*   and
org.eclipse.update/.manager/*
under WEB-INF/platform/configuration. 

Details of Run Time files BIRT will create :

As per organisations security policy, application will not have the write 
access to the folder WEB-INF/platform/configuration, server not allowing 
to create the BIRT run time files.

We need to find alternative to way to create the BIRT run time files in 
some other location other than WEB-INF/platform/configuration. 

Please help on this if you have any work around.

Extract of source code for getting BIRT Report engine :

private IReportEngine getBirtEngine(ServletContext sc) {
 IReportEngine birtEngine = null;
 if (birtEngine == null) {
  EngineConfig config = new EngineConfig();
  config.setEngineHome("");
  IPlatformContext context = new PlatformServletContext(sc);
  config.setPlatformContext(context);
  try {
   Platform.startup(config); -- This is creating the run time 
configuration files
  } catch (BirtException e) {
   e.printStackTrace();
  }
  IReportEngineFactory factory = (IReportEngineFactory) Platform
    
createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);
  birtEngine = factory.createReportEngine(config);
 }
 return birtEngine;
}
