Birt Report Deployment error

Hi,

Iam trying to deploy a birt report that i created. I am able to preview the data set and the report correctly in the design preview and deployed the report
into MY reports by creating a report template based on the .rptdesign file in my local and when i try to open the report iam getting the following error
even though the report runs fine in the design preview format:
HTTP Status 500 - The design file <stream> has error and can not be run.
--------------------------------------------------------------------------------
type Status report
message The design file <stream> has error and can not be run.
description The server encountered an internal error (The design file <stream> has error and can not be run.) that prevented it from fulfilling this request.
--------------------------------------------------------------------------------
Apache Tomcat/5.5.23

I tried this both on jazz client and server and I did not find any log files on the Jazz client or server machines with any clue.I'm using Tomcat.
Am i doing anything wrong or Am i the only one who is facing this error or is there anyone one with the same problem/error or solutions.
Do i need to do any configurations or settings before i deploy my report, please let me know.

Regards
