Subject [jira] Created: (AXIS2-2309) Unnecessary WebServiceException if parameter is null
Date Sun, 11 Mar 2007 05:15:09 GMT
Unnecessary WebServiceException if parameter is null
----------------------------------------------------

                 Key: AXIS2-2309
                 URL: https://issues.apache.org/jira/browse/AXIS2-2309
             Project: Axis 2.0 (Axis2)
          Issue Type: Bug
            Reporter: Davanum Srinivas


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,
dims
