BPEL Process Manager Server connection :Failed

Hi all,

In the SOA Suite 10.1.3.4 and using Jdev 10.1.3.4,when trying to create the integration server connection.
The BPEL Process Manager Server fails when you check the details,the error is on the Identiy service says
"java.io.FileNotFoundException:http://:80/integration/services/testconnection/BPELConnection ".
The workaround for this is:
Login to EM console goto the oc4j instance Stop and start the hw_services
And goback to Jdev and create the connection again,it succeeds this time.

Happy learning
