Hi.
I just upgraded my birt env from 2.0.1 to 2.1 and cant run report
engine
in test project.
I have an NullPointerException at line:
IReportEngine engine = factory.createReportEngine( config );


part of my code:
EngineConfig config = new EngineConfig();
config.setEngineHome("ReportEngine");
try {
Platform.startup( config );
IReportEngineFactory factory = (IReportEngineFactory)
Platform.createFactoryObject(
IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);
IReportEngine engine = factory.createReportEngine( config );
IReportRunnable design =
engine.openReportDesign("SI_congenbill.rptdesign");
IRunAndRenderTask task = engine.createRunAndRenderTask(design);
PDFRenderContext renderContext = new PDFRenderContext();

thx.

It looks like your setEngineHome method is wrong.
Use the full path to the ReportEngine directory.
ie
config.setEngineHome(
"C:/birt-runtime-2_1_0/birt-runtime-2_1_0/ReportEngine" );

Solved after add all jars to classpath from engine\plugins directory.
Actually in my classpath are jars from ChartEngine, ReportEngine,
ReportEngine\lib, ReportEngine\plugins,
ReportEngine\plugins\com.lowagie.itext\lib.

question:
Where is documentation about which jars from birt i should add to my
classpath ?

Thx.

If this is a standalone application all you should have to add is the
reportengine/lib jars.
The plugins directory is auto discovered.
