ReportEngineFactory ClassCastException (BIRT 2.2) [message #248021]

Hi,

Running a report using BIRT 2.1 works fine, but when I run the same report
with BIRT 2.2 gives the following problem:
The first running works fine, but the second running gives the
ClassCastException.
java.lang.ClassCastException:
org.eclipse.birt.report.engine.api.impl.ReportEngineFactory

My code:

// The parent classloader

ClassLoader parentLoader = ReportPlugin.class.getClassLoader();

// Load the class with our own classloader.

URLClassLoader loader = new URLClassLoader(new URL[] { classesDir.toURL()
}, parentLoader);

Thread.currentThread().setContextClassLoader(loader);

Platform.startup(econfig);

IReportEngineFactory factory = (IReportEngineFactory)
Platform .createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_E NGINE_FACTORY);

HashMap appContext = new HashMap();

appContext.put(EngineConstants.APPCONTEXT_HTML_RENDER_CONTEX T,
renderContext);

appContext.put(EngineConstants.APPCONTEXT_CLASSLOADER_KEY,
Thread.currentThread().getContextClassLoader());

Any help?

Thanks

Is this correct solution? [message #248331 is a reply to message #248021]

If I delete the line Platform.shutdown();, it works fine.

Is it correct to leave the platform running?

Ideally in an application you only want the platform to shutdown on
application exit. It is expensive to start.
