SAP EP Portal & Excel VBA

Hi,

I am trying to integrate an Excel application with VBA macros reading Excel data files and I was wondering what is the best solution to execute this Excel/VBA apllication within the SAP EP 6.0.

Is there any Excel plugin for SAP EP 6.0 so that the Excel/VBA is executed on the server ? (the client should be able to see the Excel result without Excel installed)

Is there any way to launch this Excel/VBA file from a Java web client integrated in teh portal ?

Thanks.
