none of the ESS page open in portal

Hello,

I have done configuartion for ess on portal and ecc side. But when I click on ESS tab in portal there are two problems. First problem is portal login screen appears and I have to enter userid and password again. Other problem is when I enter userid and password overview and other area pages open but pages for different applications under each area does not open. for example when I click on personal information tab it shows initial page but when I click on address link, page does not open. An error message "javascript:void(0)" appears in the bottom.

I guess this problem is related to navigation.

Please provide solution for this.
