We tried to access the Soap based requesting mechanism for project server 2013. For loginforms we found the below way to generate the request XML's in SoapUI using their end WSDL.
The Requests and Response were successful. Now to the connect to figure out the Projects we used the below:
In this case, when trying with the endpoint "ReadProjectList" we ended up with no response

The same when simulated with Java Code gave: Exception in connecting the MSProject server ,HTTP transport error: java.net.ConnectException: Connection refused: connect
Please suggest on possible ways on resolving this discrepancy!
