Andreas Veithen updated AXIS2-4393:
-----------------------------------
Fix Version/s: 1.6
> JAXWS: If JAXB classes are not packaged with the JAXWS Application, the
> service may fail
> ----------------------------------------------------------------------------------------
>
> Key: AXIS2-4393
> URL: https://issues.apache.org/jira/browse/AXIS2-4393
> Project: Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: jaxws
> Reporter: Rich Scheuerle
> Assignee: Rich Scheuerle
> Fix For: 1.6
>
> Original Estimate: 2h
> Remaining Estimate: 2h
>
> Under normal circumstances, a JAX-WS web service application uses JAXB
> classes to represent the method and parameter data
> for document/literal operations. However, very simple web service
> applications may not contain JAXB classes.
>
> For example, a JAX-WS document/literal method that only has Java primitive
> parameters might be developed without JAXB classes.
>
>
> Another example is a benchmark application. A benchmark application that is
> developed by other vendors and might not contain JAXB classes
>
>
> If JAXB classes are not present, the JAX-WS runtime will perform correctly in
> most cases.
>
> When the following conditions are met, the JAX-WS runtime will fail with a
> NullPointerException error:
> * The JAX-WS web service has a style/use defined as document/literal.
>
> * The JAX-WS web service is defined as or defaults to the wrapped mapping.
>
> * The JAX-WS web service does not contain JAXB classes.
> * The JAX-WS web service receives a message that indicates that one of the
> parameters to the JAX-WS operation is null or missing.
>
>
> The NullPointerException will occur when the JAX-WS runtime
> receives the incoming message. Here is an example error:
>
> javax.xml.ws.WebServiceException:
> java.lang.NullPointerException
> at
> org.apache.axis2.jaxws.ExceptionFactory.createWebServiceException(ExceptionFactory.java:175)
>
> at
> org.apache.axis2.jaxws.ExceptionFactory.makeWebServiceException(ExceptionFactory.java:70)
>
> at
> org.apache.axis2.jaxws.ExceptionFactory.makeWebServiceException(ExceptionFactory.java:128)
>
> at
> org.apache.axis2.jaxws.marshaller.impl.alt.DocLitWrappedMinimalMethodMarshaller.demarshalRequest(DocLitWrappedMinimalMethodMarshaller.java:221)
> Solution:
> In the scenario described above, the JAX-WS unmarshalling engine uses an
> algorithm called "document literal wrapped minimal" unmarshalling.
> The algorithm currently does not have the ability to recognize missing
> elements/parameters.
> The algorithm will be upgraded to handle this scenario.
> In addition, other clases in the JAX-WS runtime were changed to provide the
> necessary information to detect the missing parameters.
> This solution has been tested and will be committed shortly. All of the code
> is in the JAXWS runtime.
