Problems with generated wsdl when using non service package.

I'm using wsdl2java to generate a proxy to a Tuscany webservice - this
is working well in most cases, however I've found a situation where it
does not....

When I have defined a parameter to an operation which does not reside
in the same package as the service itself, then the wsdl generated
does not respect the appropriate namespace required for such clients
to be able to process the wsdl appropriately.

I've attached an example scenario which demonstrates this:

o ws-common and ws-webapp being the service which generates the wsdl
through ?wsdl
o ws-client uses the axistools-maven-plugin:wsdl2java goal to process the wsdl

So the client fails with the following error:

Embedded error: WSDL2Java execution failed
Type

WSServicePOJO is referenced but not defined.
