Error while viewing report in JasperServer and iReport

[dineshsh]

I have customized `JasperServer`.
I am using `PostgreSQL` database with `JasperServer`. I have imported reports. However I am not able to view those reports in `JasperServer` as well as `iReport`.
When I view it like xml it shows a long number.

Please help me to resolve this issue if anyone have configured **JasperServer** with **Postgres** database.

***Note: There is no issue when I use MySQL database***

It throwing following exception when I try to execute the report.
Error loading the report template
