there is a check for null value and a WebServiceException is thrown. There is a comment just
before this code that says the following.
> =====================================================================================
>              // TODO This needs more work.  We need to check inside holders of input
params.  We also
>              // may want to exclude header params from this check
>              //Validate input parameters for operation and make sure no input parameters
are null.
>             //As per JAXWS Specification section if a null value is passes as
an argument
>             //to a method then an implementation MUST throw WebServiceException.
> =====================================================================================
> *BUT* this is not correct reading of the jaxws 2.0 spec (Page 39) says the following:
> =====================================================================================
> Due to the limitations described in section 5.3.1 of theWS-I Basic Profile specification
(see [8]), null values
> cannot be used as method arguments or as the return value from a method which uses the
rpc/literal binding.
> } 
> Conformance (Null Values in rpc/literal): If a null value is passed as an argument to
amethod, or returned
> from amethod, that uses the rpc/literal style, then an implementation MUST throw a WebServiceException.
> =====================================================================================
> So the WebServiceException for null parameters is not applicable to doc/lit/bare. it's
required only for rpc/lit.
