Java.sql.SQLException: Closed Connection error when invoking web service

Question

Hi
I've assembled a simple web service for an Oracle PL/SQL package and deployed it on a Standalone OC4J, when I come to invoke it on the Oracle Enterprise Manager screen I'm getting the following returned within the envelope body:
<env:Body>
<env:Fault>
<faultcode>env:Server</faultcode>
<faultstring>Internal Server Error (serialization error: java.sql.SQLException: java.sql.SQLException: Closed Connection)</faultstring>
</env:Fault>
</env:Body>
The function that is called within the database returns a user defined object that consists of a RAW value and an XMLTYPE. The function takes a string as a parameter, when I enter a string that I know will not return an object there is no error in the envelope body, only when there is an object to return does the error appear.
Anyone have any suggestion as to why this is?

Answer 1

I'm no further forward with this: has anyone assembled, deployed and invoked a web service that returns a XMLTYPE?? I know this should be possible but I think there's maybe some manual intervention required with the classes created with webservicesassembler: I'd really appreciate it if anyone with any experience of this kind of thing could help me think this through.
