Hello,
OK I have successfully gotten my web application to use the BIRT Report
Engine to create reports using the Report Engine copied ('installed') to
a folder on my system.
I would prefer to have it as part of the web application. But I am
having trouble finding examples to see how this is done
The BIRT Viewer web application (Birt.war contained in the
birt-runtime-2_1_0) is exactly what I want to do, bundle the Reporting
Engine in the web application preventing the need to 'install' the
Report Engine to the local file system
However have tried to find the code for the WebViewerExample and I don't
know where to look.
I see that the required libs and the 'platform' (contains the eclipse
plugins etc...) are placed in the WEB-INF dir but what do I use for the
config.setEngineHome?
With the Report Engine 'installed' in a folder on my system I use the
following code to init the report system
....
if( rptEngine == null ){
EngineConfig config = new EngineConfig();
config.setEngineHome("C:/Development/BIRTStuff/birt-runtime-2_1_0/ReportEngine ");
rptEngine = new ReportEngine( config );
}
....
With the Engine bundled in my application war what do I use?
What else do I need to do to get this to work??
Thanks for your time.

BTW, I have added some examples on the Eclipse Wiki.
