IScriptedDataSetEventHandler and classpath [message #255906]

Fri, 21 September 2007 05:55

Eclipse User

Hi,

Is there a way of making an IScriptedDataSetEventHandler implementation
class visible to BIRT from a different plug-in. I have an RCP application
which has a scripted data set event handler which I need to make available
to the BIRT report designer in preview mode.

I have tried exporting the package with the relevant class in my plug-in but
when attempting to preview the report I get:

Error.ScriptClassNotFoundError ( 1 time(s) )
detail : org.eclipse.birt.report.engine.api.EngineException: Class
com.test.ui.rpt.birt.ReportDataSetListener not found
at
org.eclipse.birt.report.engine.script.internal.ScriptExecuto r.getInstance(ScriptExecutor.java:107)

Regards
Jos

Jose,

Take a look at this article
http://www.eclipsezone.com/articles/eclipse-vms/

Here is a message that Darek posted on this NG.

This article DID HELPED A LOT!!!

I don't know if this is a "proper" solution, but when I added a:

Eclipse-BuddyPolicy: registered

to /META-INF/MANIFEST.MF in org.eclipse.birt.report.engine_x.y.z.jar and
then:

Eclipse-RegisterBuddy: org.eclipse.birt.report.engine

to my plug-ins manifest it worked!!! No more ClassNotFoundException at
all!!! Without even setting anything by System.setProperty(*, *);

I did the same to org.eclipse.birt.report.viewer, but that was to mak=
e =

javasript able to access classes inside the drivers.

Wouldn't it be a good idea to have "Eclipse-BuddyPolicy: registered" =
in =

these two plugins? Then it would not be necessary to tweak birt =

installation to get classloading working properly.

I have already requested this for org.eclipse.birt.report.viewer in t=
his =

bug report:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=3D202049

It might also be a good idea to have a page about classloading issues=
=

and solutions in the faq/wiki/wherever - these seem to come up in the =

newsgroup a lot.

I was hoping for a solution that did not involve modifying the BIRT
installation but the workaround you have provided is simple and really
useful nevertheless.

Thank you both for your replies.
