Plugin classloader problem [message #298357]

Hi all,

If I run my plugin (runs a BIRT script file) as a standalone it works
fine. But when it runs as Eclipse plugin gives the following error:

Script engine error: TypeError: [JavaPackage nl.fields.DynamicFields] is
not a function. (DataSet:Set.open#12)

The following package is exported in the manifest file of my plugin:

Export-Package:
nl.fields

Any idea why my class is not loaded?

Thanks,

Said

Which plugin is your plugin and which plugin is BIRT? Who depends on whom?

My plugin: is a plugin which I have self implemented.
BIRT: is a Business Intelligence Reporting Tool.

My plugin uses the APIs of BIRT in order to run a BIRT script file.
The problem is that the objects of my plugin that are called in this
script couldnt be found.

Right, so without buddy classloading, the BIRT plugin cannot load your
stuff.

Search for similar problems in this newsgroup.

Said, you need to look up eclipse classloading.

google with a couple of different variations on:
site:dev.eclipse.org news.eclipse birt script engine error

This does return references to the kind of problems, with "some"
solutions (they look like non-eclipse solutions to me).

And I'd describe your usecase (and the part that doesn't seem to be
working) in the eclipse.birt newsgroup ... someone there might have
tried the exact same thing.
