Hi all,
Some time after posting my question to the newsgroup (at bottom of mail), I
got a reply from Achim Abeling outlining a possible solution.
I'm actually working on a different project at the moment and so haven't
been able to test whether this is actually the right solution, but since it
might be some time before I get to try it out, I thought it worth posting in
case it could help someone else.
Cheers,
Phil

Subject: Re: String[] in complex type was returned as null
Hi Phil,
i got the same problem with a String array.
After a lot of debugging in the Axis code I found that the
BeanDeserializer did not find an appropriate Deserializer for my String
array. In my case the SOAP element lacked an xsi:type attribute which
was the cause, I think.
I managed to get my code doing what I want by
- adding a org.apache.axis.description.TypeDesc for my custom bean. I
got a hint for that by generating code with wsdl2java and inspecting the
code created for the bean
- registering a TypeMapping for the String array in the call
call.registerTypeMapping(
String[].class,
new javax.xml.namespace.QName(
"http://www.w3.org/2001/XMLSchema";,
"string[]"),
ArraySerializerFactory.class,
ArrayDeserializerFactory.class);
Perhaps this helps you, too.
I did not manage to mail this directly to the mailing list because I do
not have the original mail. I only saw your post at
http://marc.theaimsgroup.com
If you find my answer useful, perhaps you can mail to the mailing list.
Best regards
Achim Abeling
