Export from Java report viewer issue

Hi all,

I am trying to export a report from Java report viewer and get the following message:

com.businessobjects.crystalreports.viewer.core.rs.b$e cannot be cast to com.crystaldecisions.xml.serialization.IXMLSerializable

This happens whatever format I choose to export to. I guess I imported the wrong package... Any idea?

Also while trying to export a file to my desktop (MS Vista), I get a message says no write access to the selected file. Is this a setting issue? Can report be exported to desktop?

Regards,

Dong
