As I try to open this jrxml file via iReport Designer, it show the same error message


Root Cause
As I change iReport mode from Designer to XML, I figure out the root cause. This jrxml file had broken for unknown reason, it's an empty jrxml file so it cannot be compiled correctly.

THerefore, I need to revert this file to server version by svn client, and do it again.
