Hi,
First I like to thank the BIRT team for the great tools you put in our
hands!
We have already integrated the report engine i our web-applications and
now we are taking the next step.
We are trying to integrate the engine part of birt in our existing
rcp-application. At this date we don't want the designer and viewer,
only the engine so we can generate html and pdf-reports from existing
report design files (.rptdesign).
Our first approach would be to just add the birt-runtime-2_0_1/Report
Engine to the plugin that needs to generate reports.
We have a problem with that approach because we believe that it should
be possible to just add dependencies on the required plugins (everything
is plugins i eclipse, why add the report engine as something else?).
This would probably make it easier to perform updates in future because
we don't have to distribute the birt report-engine within the plugin
that is using it.
So after reading a bit about the plugings that BIRT consists of and what
dependencies they have to each other I ended up adding the following
plugins to our rcp application target:
org.eclipse.birt.core_2.0.1
org.eclipse.birt.data.oda_2.0.2
org.eclipse.birt.data_2.0.1
org.eclipse.birt.report.engine.emitter.html_2.0.1
org.eclipse.birt.report.engine.emitter.pdf_2.0.1
org.eclipse.birt.report.engine_2.0.1
org.eclipse.birt.report.model_2.0.1
org.eclipse.datatools.connectivity.oda_3.0.0
org.junit_3.8.1
....and I added dependencies on these plugins in the plugin that will be
responsible for generating reports.
We use a scripted data source in our reports and when I try to execute a
report, Birt don't seem to know about my java-classes (see log below).
How can I solve this classloadning problem? (if it is a class loading
problem...) And last but not least do you think it is possible to
integrate BIRT the way I'm trying to do? Or should I give up and go back
to the thread "Re: Integrate Birt in RCP" from 2006-03-24 and follow the
steps there despite i dislike to integrate birt in that way?
Ideas?
Best regards
Erik Mellegård

Erik,
I havent tried it this way. I normally just add the RE jars to my RCP
application.
That said I would think that this would work. Have you tried adding a class
folder to the application (using the Build Path) and putting your pojo
there? Using this method where you able to run a report off the sampledb?
Thanks
Jason

Hi,
Thank you for your rapid reply.
Now I have tested to generate a report from a design using the
sample-db. It worked perfectly after adding the two following plugins:
org.eclipse.birt.report.data.oda.jdbc_2.0.1
org.eclipse.birt.report.data.oda.sampledb_2.0.1
From this I draw the conclusion that it is possible to use the birt
engine this way, which I feel good about.
My problem with the scripted datasource still exists though.
I have tried to add my POJO-jar-file to the build classpath with no
successs.
I also tried to register my plugin (which contains my POJOs) as a
"Buddy" to org.eclipse.birt.report.engine. by adding the following line
to my plugin manifest file
Eclipse-RegisterBuddy: org.eclipse.birt.report.engine
Other ideas? How can i tell the report engine class loader to look for
the classes in my plugin?
Best regards
Erik

Erik,
I got this to work with my example by creating a classes directory in my
project.
I uploaded my POJO and then on the Runtime tab of my plugin added the folder
to the Classpath.

Hi,
I guess that the problem was that my POJOs were embedded inside a
jar-file that made them invisible in some way to the BIRT script
runtime. I solved the problem by adding my factory object as a
ScriptableJavaObject to the task before calling task.run(). Now the
report nows about my classes.
Thanks again for your rapid replies.
