> A service returns an array of JavaBeans that is of length 0.
> The client gets an exception "Unexpected subelement"
> This may be related to bugs 2464 and 1702
> To provide some clarity, I will attach a version of sample/addressbook. I've made the
following changes:
> (1) In the service, I've added methods to return arrays of Entry:
>   public Entry[] getEntries1() {
>     return new Entry[] { createEntry(), createEntry() };
>   }
>   public Entry[] getEntries2() {
>     return new Entry[0];
>   }
> (2) Then I exercise both methods in the client as follows (the call to getEntries2 fails):
>             GetEntries1Response e1Response = stub.getEntries1();
>             Entry[] entries1 = e1Response.get_return();
>             System.out.println("Number of items returned by getEntries1(): " + entries1.length);
>             GetEntries2Response e2Response = stub.getEntries2();
>             Entry[] entries2 = e2Response.get_return();
>             System.out.println("Number of items returned by getEntries2(): " + entries2.length);
> I did it this way so that the fact that an array of length > 0 is obvious.
> If I had time, I'd check with simple types, but in my case, a bean is the most important
object type I need to return in an array.
> Idea:
> There seems to be a whole cluster of small issues around the POJO service + ADB client.
E.g., methods that return void, exception handling, etc. A somewhat more robust version of
sample/addressbook might bring these out. I'd be glad to beef up the example . . .
> I think the POJO service + ADB client is key for the Axis2 "product" because if the simplest
entry point is awkward, people will just bag it and use other impls of the various  APIs.
