Open document in 4.1 Sp02

Hello All,

After installing the BOBJ 4.1 sp02 , when i go to document link from context menu of web i report , the link has port 6405. in 4.0 it used to be 8080. Is this a known change in 4.1?

Also, SSO is not working for open doc with default (6405) port, however it works if i change the port number to 8080 in the url.

How can i change the default port of open doc to 8080?

If 6405 is default than how can i enable SSO

Thanks

Karthik
