I have configured TREX server in my server and able to ping it from my WebAS server. I have also configured the "catalogSiteConfigFile" in the XCM configuration to the actual location of the R3 Site Config XML file location.
After this configuration I had restarted the server to take this in effect and when I connect to the "trexr3/b2x/admin/init.do" it doesnot display the Catalog site in the left navigation menu and displays "Exception from the PCAT API: Fatal Error: Could not create the Catalog Site !!!" & "Exception from the PCAT API: null".
Please let me know if there are any other configurations to be made.
The XML file is placed outside the WebAS directory structure and the folder has full permissions.
Thanks in advance for your valuble help.
