SDO Java serialization/deserialization throws an exception when the serialized
data object is not the root and its container is of AnyTypeDataObject
----------------------------------------------------------------------------------------------------------------------------------------------------
Key: TUSCANY-1132
URL: https://issues.apache.org/jira/browse/TUSCANY-1132
Project: Tuscany
Issue Type: Bug
Components: Java SDO Implementation
Affects Versions: Java-SDO-M3
Reporter: Fuhwei Lwo
Fix For: Java-SDO-M3
With or without the patch of TUSCANY-1131 to fix the problem in
XMLDocumentImpl.java, this problem always exists. With the fix from
TUSCANY-1131, now I got this exception. I believe there are still some problem
in the SDO Java serialization/deserialization code.

PROTECTED] (eClass: [EMAIL PROTECTED] (name: DataObject) (instanceClassName:
null) (abstract: true, interface: false))' is not legal. (http:///temp.xml, 3,
