Hi!
I'm actually trying to use BIRT in a RCP application to create some nice
reports in PDF. I'm using hibernate, so I want to use some POJOs as data
source for my report. I found all these tutorials saying that I have to
put my classes into the WEB-INF/lib directory of the viewer plug-in -
but I'm not using this plug-in! So where to put the classes?
I am not very comfortable with putting an artifact under development
into a folder of my target platform.
As far as I understand, this whole WEB-INF hack is only necessary to
give the scripting engine access to my classes. But why not simply using
buddy classloading for that? Then I would simply have to put something like
Eclipse-RegisterBuddy: org.eclipse.birt.core
into my MANIFEST.MF and everything will be fine - at least at runtime.
Am I totally on the wrong track? Did you ever think about this?
Sincerely,
Florian

Buddy classloading did not help either - I could not find out where to
register the buddy. I tried birt.core, birt.data and birt.report.engine.
So I gave up this idea.
But I found another solution: I set an array with all objects via the
IRunAndRenderTask.addScriptableJavaObject method and used this variable
to get access to my objects (varName is the name of the scriptable java
object):
open:
count = 0;
fetch:
if (count < varName.length) {
row["row1"] = varName[0].getName();
....
count++;
return true;
}
return false;
This works. I don't know if I found a new solution for this problem, but
I thought I better write it down anyways. Maybe that helps anybody.
Best Regards,
Florian
