Internal Server Error (NullPointerException) when invoking a Web Service [message #249616] Thu, 05 July 2007 03:49

I'm using SOA suite (incl the latest patch set) on Windows XP.

I've created 3 web services using the wizard interface out of 3 existing WSDL files. The Java code inside the web services is just dummy code.

I'm testing the web services using the Test Web Service functionality in Oracle Enterprise Manager's Application Server Control.

The moment I fill in the data and press invoke, I get back the following fault:
<faultstring>Internal Server Error (Caught exception while handling request: java.lang.NullPointerException)</faultstring>

I know that control never reaches inside the services themselves.

I've even followed the online demo that shows users how to create, deploy and test a Web Service in JDeveloper to make sure that I wasn't doing anything silly.

What could be wrong? Please help.
Thanks in advance.
