PK83463: CLIENT RECEIVES NULLPOINTEREXCEPTION WHEN RUNNING WEB SERVICE WITH A NULL FIELD

APAR status

Closed as program error.

Error description

An incoming webservice message may contain xml elements that
are defined as null.  An example is inQName within the
following message:


-----------------------------------
<s:Envelope xmlns:a="http://www.w3.org/ 2005/08/addressing"
xmlns:s="http:// schemas.xmlsoap.org/soap/envelope/">
<s:Header />
<s:Body>
<RetQName xmlns="http://tempuri.org/">
<q:inQName i:nil="true" xmlns:i=
"http://www.w3.org/2001/ XMLSchema-instance" xmlns:q=
"http://tempuri.org/" />
</RetQName>
</s:Body>
</s:Envelope>
----------------------------------

The JAX-WS engine that receives the message may fail with a
NullPointerException error.  The NullPointerException will
indicate the location where the exception occured.  Here is an
example from the FFDC log:

Caused by:
org.apache.axis2.jaxws.wrapper.impl.JAXBWrapperException:

An incoming webservice message may contain XML elements that
are defined as null.
An example is inQName within the following message:

-----------------------------------
<s:Envelope xmlns:a="http://www.w3.org/ 2005/08/addressing"
xmlns:s="http:// schemas.xmlsoap.org/soap/envelope/">

</RetQName>
</s:Body>
</s:Envelope>
----------------------------------

A nil element, like inQName, is unmarshaled to a null Java
object by the JAX-WS runtime.  In some cases, the JAX-WS engine
may fail with a NullPointerException.  The root cause of the
exception will indicate a problem in a class named
PropertyDescriptorPlus.  Here is an example exception:

java.lang.NullPointerException
at
org.apache.axis2.jaxws.utility.PropertyDescriptorPlus.get(Proper
tyDescriptorPlus.java:139)
at
org.apache.axis2.jaxws.wrapper.impl.JAXBWrapperToolImpl.unWrap(J
AXBWrapperToolImpl.java:90)
... 29 more

The webservice runtime class, PropertyDescriptorPlus, has an
invalid check that is causing the NullPointerException.

Problem conclusion

The PropertyDescriptorPlus class was corrected to remove the
invalid check.  The NullPointerException will no longer occur,
and the data will be unmarshaled correctly.
