Null values for web service parameters
If I have a WS with the following signature:
public void doSomething( Object param1, Object param2, Object param2 );
Not all params are required. If I call the service via a client and for example param2 set to NULL I get the following exception:

Re: Null values for web service parameters
Posted by Daniel Kulp <dk...@apache.org>.
Any chance you could re-test with the latest SNAPSHOT? See the bottom
of:
http://incubator.apache.org/cxf/download.html
I did a LOT of work the last several days with issues around parameter
ordering, null values, etc... There's a good chance this is now
fixed. (If the service is Doc/Lit/Wrapped which is the default. If
the service is Rpc/Lit, there isn't a way to do null parameters as the
WSI BP specifically prohibits RpcLit parts from having xsi:nil.)
