On implementing the Service Invocation Framework there is a good blog-article here.
I found myself running into an error using the "raise in java" button from the test screen. And I was pretty sure that my values were ok.
The error was:
1 2 3 | Exception occured in Java Raise - Exception when Invoking Web Service -> oracle.apps.fnd.wf.bes.InvokerException: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message send failed: For input string: "" |
