So I was putting together a demonstration on using the xsd:extension element in
a WSDL, using JBoss 4.0.3SP1 which uses the ws4ee webservices. I created the
WSDL which accepted an array of base objects as input. My service took these
and using Log4J displayed the classes to demonstrate that you can define a base
object and inherit from them in the WSDL.
This worked fine, until I added a new method to accept a base object and just
return it as a base object. Here to demonstrate that it gets sent back
correctly. But, it doesn?t. I received the following error:
Exception in thread "main" java.rmi.RemoteException: Runtime exception; nested
exception is:

So after a little research I modify my ws4ee-deployment.xml to specify an
ordering of the elements returned since from this message it appears to me that
the trouble is that the elements are returned in the wrong order, and after
dumping the SOAP messages with Log4J I see that they are the opposite of what I
was expecting. So I modified my file from:
<typeMapping
| xmlns:ns="http://ist.com/examples/extension/v1.0/";
| qname="ns:DirectoryObject"
| type="java:com.ist.examples.extention.generated.DirectoryObject"
| serializer="org.jboss.axis.encoding.ser.BeanSerializerFactory"
| deserializer="org.jboss.axis.encoding.ser.BeanDeserializerFactory"
| encodingStyle=""
| />
To:
<typeMapping
| xmlns:ns="http://ist.com/examples/extension/v1.0/";
| qname="ns:DirectoryObject"
| type="java:com.ist.examples.extention.generated.DirectoryObject"
|
serializer="org.jboss.webservice.encoding.ser.MetaDataBeanSerializerFactory"
|
deserializer="org.jboss.webservice.encoding.ser.MetaDataBeanDeserializerFactory"
| encodingStyle="">
| <typeDesc xmlType="ns:DirectoryObject">
| <elementOrder>
| <element name="name"/>
| <element name="location"/>
| <element name="fileEntries"/>
| </elementOrder>
| </typeDesc>
| </typeMapping>
And still the same problem, and after looking at the SOAP message in my log it
appears this change had no effect.
This only happens when I am returning an item of the base type to the client.
The server and the client were generated with JSWDP 1.6
Now I reset the mapping file back (which you will see has no bearing) and tried
the same test on the 4.0.4CR2 and it works picture perfect. So while the
obvious answer is to upgrade to 4.0.4CR2 ? the fact of the matter is I can?t
until 4.0.4 is actually released. So ? what can I do?
