Solution :
Go to this location
<drive>:\OrangeScape\Server\DimensionServer\server\default\deploy
\Reports.ear\Reports.war\WEB-INF\web.xml
Find "Eclipse BIRT Report Viewer" and replace with "Reports" in the
file web.xml
For eg :
<web-app>
<display-name>Reports</display-name>
<!-- Default locale setting -->
Restart the application server and you can find the reports in the
corresponding pages as configured before.
