Improper deserialization of composite types
In my application, I need to represent a tree-like structure. In order to do
this, I constructed the type Entry, which -- among other properties -- has a
parent (which is also an Entry) and a collection of children (a
java.util.TreeSet containing zero or more objects of type Entry). Through
axis, I can access the server-side methods getByID() and getByNotation()
which both return an Entry including the entry's immediate children (but no
grandchildren) and the entry's parent including all ancestors (but no
siblings). If I, however, try to access an entry in the middle of the
hierarchy, the deserialized answer only returns the requested entry itself
and its children, but entry's parent is null. I'm not a SOAP-expert
(yet...), but the returned SOAP-response seems OK to me. If I access the
methods without going through SOAP (i.e. through a jsp), I get the expected
answer. Has anyone had similar problems before and/or could point me to a
possible solution?
I enclose the request and the response (from TCPMon)

Best regards and thanks in advance
P.S. I noted that the server sends no content-length. Is this on purpose?
