Rich Scheuerle commented on AXIS2-2309:
---------------------------------------
Background:
A doc/lit base parameter is always represented by a root element.
Root elements cannot have occurrence attributes (i.e. minOccurs=0) per the XML
Schema specification.
Thus java null must be represented by an element with a xsi:nill=true attribute.
Example:
<foo xsi:nil="true" />
-------------------------------
This issue will be used to
1) Make sure that the JAX-WS layer supports null java objects for doc/lit
bare parameters.
2) Make sure that the JAX-WS marshalling code correctly sends the null using
xsi:nil.
3) Make sure that the JAX-WS unmarshalling code accurate receives and
processes null values.
Thanks Dims for the heads up. This may take a few days to assess.

> Around line 280 in
> src/org/apache/axis2/jaxws/marshaller/impl/alt/DocLitBareMethodMarshaller.java,
> 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 3.6.2.3 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.
> thanks,
