I am new to SRM-MDM and I am facing the following issues. Anybody can help me?. Full points rewarded

Issue 1.

When I try to connect to the server by using the UI configuration URL http://<J2EEserver:J2EEport>/webdynpro/dispatcher/

/tc~mdmsrmui/MDM_SRM_UI_App, after providing the IP address I am getting the message ‘Connection to the server failed’. I am calling this as stand alone.

Issue 2.

Another issue is while shopping cart creation, when I click on the MDM catalog I configured earlier, I am getting the MDM_SRM_UI_Application screen and the URL is http://<J2EEserver:J2EEport>/webdynpro/dispatcher/ and it is asking the Login info such as user name, password, transport configuration etc. What user name and password I have to provide here.
