Exception while generating report with report design using report library master page

While use report engine to generate report, I got an exception, the report design references to simple master page that defined in the library.
The exception message is:

Hi bitisony,

Can you recreate this issue with the sample database, so I can run the report? Thanks.

bitisony

OK.
Let me try.
I use xml as data source currently.

Thank you very much for your reply.

mwilliams

bitisony,

As long as you pass along the xml source file, that would be fine too. Just as long as I can run the report.

bitisony

I have tried using BIRT default DB, I got the same exception.
My test report library and report design are at attached.
Please help me to check them.

Thank you very much!

bitisony,

Sorry, I forgot to ask... What version of BIRT are you using?

bitisony

The birt version is birt-runtime-2_3_2

mwilliams

bitisony,

I ran the sample report you posted on Tomcat with the 2.3.2 viewer and received no errors. Where are you placing your library file?

bitisony

Thank you very much for your time.

My report design is at <project>/com/trpz/rm/server/reports.
and library is at <project>/com/trpz/shared/common/reports.

I know how to fix this problem by setting the resource path.
What I think is that why BIRT does not support use class url resource loader to load library?

Thanks!
