Currently i'm generating OpenErp reports as PDF format from RML code using "OpenErp report Designer" in openoffice .

But  how can I generate the report in xls format instead of PDF using same RML code.

I read some forum regards this, many of them suggest to go with jasper Report or Aeroo. But i don't know how to setup these two.

If you have any solution / answer please Let me know .

Thanks.
