Hi all,
Any one know of a way to tell whether an emitter (such as the pdf emitter)
is installed programmatically? In other words, I'd like to detect the
emitter is not there and give a friendly message back if it's not there.
Instead of trying to generate the report and getting this exception back:
EngineException: org.eclipse.birt.report.engine.api.EngineException: Report
engine fails to create extension to handle this request.
I'd like to not just catch the exception because from the message, it looks
like it could mean other errors too, not just that the emitter is not found.
Thank you for the help, Dan

BTW if you are using the engine api you can use the follows methods to
get info on the available emitters.
String[] eo = engine.getSupportedFormats();
EmitterInfo[] ei = engine.getEmitterInfo();
