We have a load-balancer link to a web service that has an underscore in the DNS name, ex. webservice_test.com. When PAM tries to run a web service call against that link the SOAP call fails and provides the following error message:
"SOAP invocation failed: java.security.PrivilegedActionException: com.sun.xml.messaging.saaj.SOAPExceptionImpl: Message send failed"
From this message is is very unclear as to what the problem is. Having an underscore in the DNS name for the load balancer might not be the best practice but it is supported and many other tools outside of PAM have no issues with this. I would ask that PAM be able to handle this or at least display a better error message as to why the operator failed. As a process designer when things work perfectly fine outside of PAM and then you try to build a process with them and run into issues like this it can be extremely frustrating.
