Dynamic proxy on jwsdp 1.1 deserialization error

Question

Hi,
I want to use a dynamic proxy to get information from an webservice.
normal datatypes like String or integer works fine. But when I want to have an object back, I get an deserialization error. I use sdk 1.3.1_08 and the jwsdp 1.1
Does the jwsdp 1.1 support to transfer objects with dynamic proxy?
thx
Matthias

Answer 1

I must use the jwsdp 1.1 because our clients run on IBM-Webspehre the highest sdk wich is at the moment supported is sdk 1.3.1_08.
But with the jwsdp and sdk 1.4.2 I became also an exception.
her it is:
UrlString = http://localhost:8080/uisservice/endpoint?WSDL
