This happens when there is other application which is also using the same port 8880. To resolve the issue, we need to find which application is using the port 8880 through 'netstat' command in command prompt or update our WAS server to not use 8880. We can update the WAS server through these steps: 1) Stop WAS. 2) Browse to or search for the serverIndex.xml, for example, at "C:\WAS\AppServer\config\yourNode\nodes\yourNode\serverindex.xml" 3) Open the file and locate the following lines: endPointName="SOAP_CONNECTOR_ADDRESS"> 4) Change "port 8880" to an available port 5) Save the serverindex.xml and restart WAS
