Jason,
I am back with the same problem I post two week ago but with more
informations.
I attached the source from CVS to the class to see where the error came
from.
Inside the
org.eclipse.birt.report.engine.extension.internal.ExtensionM anager class,
then inside the loadGenerationExtensionDefns() method,
Platform.getExtensionRegistry() = null.
You spoke me the first time about a "Platform registry" not found. Can you
tell me more to resolve this error please ?
I have Eclipse 3.2. This is the files I downloaded :
- birt-report-designer-all-in-one-2_1_0.zip
- birt-runtime-2_1_0.zip
- itext-1.3.jar
The code where factory = null :
IReportEngine engine = null;
EngineConfig config = null;
try{
config = new EngineConfig( );
config.setEngineHome("C:\\birtruntime\\birt-runtime-2_1_0\\ReportEngine ");
config.setLogConfig(null, Level.FINE);
Platform.startup( config );
IReportEngineFactory factory = (IReportEngineFactory)
Platform.createFactoryObject(
IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY );
engine = factory.createReportEngine( config );
engine.changeLogLevel( Level.WARNING );
}catch( Exception ex){
ex.printStackTrace();
}
The error in the console :
java.lang.NullPointerException

The birt home variable lets the engine know where the OSGi plug-ins are.
They are not in the lib folder, but the plugins folder.
