runReport() method Report definition not found issue

Hi Expert

I use  the runReport() method  to run report but the following error occur

=====

<faultcode>soapenv:Server.userException</faultcode>

         <faultstring>oracle.xdo.webservice.exception.OperationFailedException: PublicReportService::generateReport for reportAbsolutePath [/users/weblogic/demo_report.xdo] failed: due to oracle.xdo.servlet.CreateException: Report definition not found:/users/weblogic/demo_report.xdo [username=weblogic]</faultstring>

=====

Base on the error, It seems that the parameter setting for <v2:reportabsolutepath> is not correct,

and demo_report.xdo is found in my environment by the following path

http://host.domain:port/analytics

catalog->user folder->my folder->demo_report.xdo folder

I will upload the screen shot for the demo_report.xdo file  and the info of request and Response
