HI all,

I'm working on a RCP application and using Birt. I managed to make a report file and preview it with WebViewer.display(...).

Now I was wandering how can I pass my report file to the WebViewer (or to the Report Engine), if it was contained in the plugin jar file. I
would like to do this just like I load images from within the plugin jar file. Is this possible or ...?

Thanks,
Bojan

I am not sure if this would work for you, but I load my reports using the
ClassLoader. Here is an example:

String reportFile = "com/yourcompany/yourapp/YourReport.rptdesign";

InputStream reportStream =
Thread.currentThread().getContextClassLoader().getResourceAs Stream();
IReportRunnable design = engine.openReportDesign(reportStream);

// Create task to run the report - use the task to execute and run the
// report
IRunAndRenderTask task = engine.createRunAndRenderTask(design);

task.run();

Obviously, the reports would have to be in your classpath, but if they are
in a jar file, I would assume you are including this jar in your classpath.

Good luck!

This is exactly what I want.
I didn't go through the Report Engine API and didn't see that you could pass an InputStream to it.
Thanks.

Great! I just noticed that I left something out in this line:

InputStream reportStream =
Thread.currentThread().getContextClassLoader().getResourceAs Stream();

It should be:

InputStream reportStream =
Thread.currentThread().getContextClassLoader().getResourceAs Stream(reportFile);

You probably already figured that out, but I figured I would correct it in
case anyone got confused.
