It looks like you are referring to the Celtix binding code from last week, I am afraid it was not complete at that stage. But the latest version should allow both inbound and outbound working, I have tested helloworldwsclient sample, it works fine. Please note there is a hack currently in Celtix binding NodeDataReader/NodeDataWriter code. I have to convert SDO object to stream first, then stream to XML Node. This is because Celtix 1.0 does not have a direct support to stax. Problem can be fixed once we move Celtix binding to be based on the latest CeltixFire code base. CeltixFire repository is already available from apache incubator. As Raymond has mentioned, a pluggable databinding framework is under construction at the moment. Before this happens, if you are keen to use other databindings such as JAXB or xmlbeans, you can do so by implementing your own NodeDataReader/NodeDataWriter.
