to be sure about this, I'd need to be able to recreate the problem with a bit of test code, and I've not played with SDO using RMI calls, but the SDO metadata associated with the namespace URI must be available when the XML document is parsed. This would be made available when either the XSDHelper is used to load a schema or generated SDO classes are registered with the environment, and it is going to need to be available in the jvm that the xml parsing is happening.
