Hello,

I'm trying to integrate BIRT in a java application. I'm using a specified
xml file for instance data in the report designer and everything is fine,
but how can I specify the XML DataSource a runtime ? I would like to pass
the XML Data as a stream, is it possible ?

Totally doable in 2.0. Fixed in this bug report:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=122865

Do something like so:
//After you have set up your report and are ready to actually run
//the report via a RunAndRender task, do this:

Map m = new HashMap();

//myInputStream is your input stream of XML data
m.put("org.eclipse.birt.report.data.oda.xml.inputStream", myInputStream);
m.put("org.eclipse.birt.report.data.oda.xml.closeInputStream ", new Boolean(true));

// Create the RunAndRender task
IRunAndRenderTask task = engine.createRunAndRenderTask(report);

//Previously defined render options....
task.setRenderOption(options);

//Set our app context so it know to use our stream
task.setAppContext(m);

task.run();

//Viola!

Thanks for the answer. Apparently, this could work, but I've got some
strange error that I believe is happening before the actual rendering, in
the model parsing phase.

The Engine is tryng to parse the model (the oda.xml extension) and booms
with an NPE ! Any idea why this could happen ?

Id: java.lang.NullPointerException
Callstack:

org.eclipse.datatools.connectivity.oda.util.manifest.Manifes tExplorer. <clinit>()

Could you post the code you are using to call the report and indicate the line where it is blowing up?

Thanks for the help, but I've tryed the code you supplied outside my
framework and it works ! Althought with some warnings...

WARNING: Cannot set statement property.
java.lang.UnsupportedOperationException: IQuery.setProperty( String
propertyName, String propertyValue )
at
org.eclipse.datatools.connectivity.oda.consumer.helper.OdaOb ject.handleUnsupportedOp(OdaObject.java:278)

This means that the problem is in the interaction between BIRT and my
framework, so I have to dig a little deeper... :)

more that one dataset it starts to give saxparser exceptions. I suspect
that this is a bug from the XMLDataInputStream trying to reopening the
stream over an over...

As anynone in BIRT come across this ?
