Oracle webcentre content integration with OHS

 Hi,
We have installed Oracle Webcentre content, Oracle weblogic and Oracle HTTP Server (11.1.1.7) in one of environment.

After we had configured OHS with weblogic, we are not able to login to the below URL:
http://192.168.1.15:7777/cs
(The login page gets displayed.
However, when we click the login button the page throws HTTP 400 Not found error.)

These are the configuration details:
Server host: 192.168.1.15
Oracle Weblogic: http://192.168.1.15:7001 <works fine, without OHS integration>

Oracle HTTP Server: http://192.168.1.15:7777

Oracle Weblogic with OHS: http://192.168.1.15:7777 <works fine, even with OHS integration>
Oracle webcentre content: http://192.168.1.15:16200/cs <works fine,without the OHS integration>

Oracle webcentre content URL with OHS integration:
