Problem generating Excel report

[eyecon1]

I'm using Actuate 5 to generate reports through Java. I am experiencing a problem exporting the report in Excel format, it displays the following error:

java.lang.RuntimeException: com\actuate\ereport\output\FormulaOneWrapper.class (The system cannot find the path specified)
at com.actuate.ereport.output.OD_Excel.generate(OD_Excel.java:182)
at com.actuate.ereport.output.VirtualOutput.generateExcel(VirtualOutput.java:2252)
at com.actuate.ereport.output.OD_Preview.generateExcel(OD_Preview.java:2405)
at com.actuate.ereport.output.OD_Preview.exportToExcel(OD_Preview.java:1354)
at com.actuate.ereport.output.OD_Preview.actionPerformed(OD_Preview.java:1543)
at com.actuate.ereport.common.uiswing.ToolBar.fireActionEvent(ToolBar.java:582)
at com.actuate.ereport.common.uiswing.ToolBar.mouseReleased(ToolBar.java:548)
...

.. but only if I run it directly from the jar. If I run it through JBuilder, it works fine. The problem seems to be that the FormulaOneWrapper uses classes in the erdj9xl.jar, but running outside of JBuilder, it can't find the jar. I've included it as a required library, set the dependencies, added the jar to the manifest, tried accessing it from different directories.

And oddly, I also have another application using Actuate 7, which I also needed to include the extra jar in (erdjf1xl.jar), and it works fine. Apart from the differences in the included jars, and the ACJRuntime.jar, there are no differences in the projects or manifests.

Any other suggestions or solutions would be GREATLY appreciated.
