Cognos 8.4.1 is not working with websphere 7

Hi,
I have Cognos 8.4.1 on my Windows 7 machine.
I am able to connect to Cognos through my application with weblogic and IIS 7.
But when I use websphere as the app server, application doesn’t connect to cognos.
I get 'CM-REQ-4342 An error occurred with the client.'
Anonymous Access is Enabled in Cognos.
Is there any specific configuration that needs to be done in websphere?

Thank you

did you read this document?

This document talks about weblogic. But, I have an issue with websphere…Is there any similar document for websphere?

Take a look at this
