migrating birt 2.3 to birt 3.7

loithoi

We used birt 2.3 and wanted to upgrade to birt 3.7 in servlet. The code looks like this

EngineConfig config = new EngineConfig();
// this causes the plug-in loader to look in the current
// directory.
config.setEngineHome("");


// set logging
config.setLogConfig(".\\Birt", java.util.logging.Level.WARNING);

// Using the PlatformServletContext will cause the OSGi loader
// to look for the
// plug-ins in the WEB-INF/Platform directory. If this directory
// does not exist create it.
// Next copy the plug-ins directory from the ReportEngine
// directory to the WEB-INF/Platform/ directory.
IPlatformContext context = new PlatformServletContext(sc);
config.setPlatformContext(context);

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


I'm getting the following error when I use weblogic to deploy the birt engine

Please, I need help....
Thanks

Can you try to remove this line:
config.setEngineHome("");

Do you have all the BIRT libs in the web-inf/lib directory?
