We use the BIRT Runtime API, and after we upgraded from BIRT 2.1.1 to 2.2
the scripting engine now fails to locate java classes referenced in the
importPackage of a report script. The classes that we use in the script are
part of the same java application that uses the BIRT Runtime API.
The exact error message is:
Aug 20, 2007 11:27:55 AM
org.eclipse.birt.report.engine.script.internal.DtEScriptExec utor handleJS
WARNING: A BIRT exception occurred: Error evaluating Javascript expression.
Script engine error: ReferenceError: "IeBirtFilter" is not defined.
(DataSource[DSS].__bm_beforeOpen#9)
Script source: DataSource[DSS].__bm_beforeOpen, line: 1, text:
__bm_beforeOpen().
Everything worked fine under Birt 2.1.1 We were getting the errors under
Eclipse 3.2. I switched to Eclipse 3.3 but still received the same errors.
Any ideas what can be causing this error? I've tried everything I can think
of. Thank you.

I have now confirmed that the javascript snippets are able to access =

classes in the driver ok when APPCONTEXT_CLASSLOADER_KEY is set as above=
..
However, this only works when embedding BIRT. I haven't found a way t=

make it work with BIRT runtime's genReport.bat nor in BIRT RCP Report =
Designer's preview. I'd need to have at least the latter one working as =
it =
will be very inconvenient to design reports and only be able to preview =
=
them correctly from the embedding app.
BTW, I need to access the classes via the same classloader that the =
driver uses. This is because I am accessing a native library and having =
=
multiple versions of the classes by separate classloaders within the sam=
e =
process would lead into problems. To put it another way, I need to acces=
s =
the same objects (the one I need is available as a singleton) that the =
driver is accessing.
Should I reopen https://bugs.eclipse.org/bugs/show_bug.cgi?id=3D18627=
2 ? =
Or is there a way to make this work? Is there something I can do in the =
=
plugin code?
