How to use script files outside the Birt RCP

Hi,

I'm using Birt 2.6.2 with Javascript.

In my RCP client I've added a script file ("C:\BIRT\MYRESOURCES\myscript.js") to "Shared Resources".
Using the RCP internal preview or the Birt Viewer, I've access to a function in that script file.

But when using that report without the RCP in a solaris environment with a BIRT HOME like /usr/local/birt-runtime-2_6_2/ReportEngine/.
I get errors like:
ReferenceError: "myFunction" is not defined. (/report/method[@name="initialize"]#9)
org.eclipse.birt.report.engine.api.EngineException: There are errors evaluating script "

I copied that script file to that BIRT HOME directory, assuming that this is the default resource directory.
But it doesn't work.

I also tried to set a resource path in the initialize script of my report and copied the file there:

reportContext.getAppContext().put("BIRT_RESOURCE_FOLDER","/usr/local/birt-runtime-2_6_2/ReportEngine/resources");

But it doesn't work also.

How to use script files outside the Birt RCP?
Do I have to add anything (a path or the file) somehow or just to copy the file to the right place?
