Hi Justin, I am afraid that you maybe have missed a key aspect of using namespaces in xml It is perfectly legal for midas to be changed to mida as midas or mida is just a prefix (shorthand) for a namespace. What is important is that the prefix is associated with the same namespace. So prefixes can change while associated namespaces are stable. When XML information is passed between systems the actual prefix is allowed to change as long as the prefix (whatever it is called) has the correct association. If your code base rely on stable prefixes I am afraid you may be in deep shit. It is not stable prefixes but stable namespaces you want. This is a common mistake concerning namespaces. XMLBeans is doing something perfectly legal. If your code cannot handle legal xml well.... /Geir

I can only speculate that XMLBeans does not like plural words. Let me describe the problem, with names changed to protect "proprietary information"... Suppose that I have an XSD schema declared approximately like so: <?xml version="1.0" encoding="UTF-8"?> . . . <xs:complexType name="Model"> <xs:attribute name="id" type="xs:string"/> <xs:sequence> <xs:element name="Type"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="Statistical" /> <xs:enumeration value="Heuristic" /> <xs:enumeration value="Bayesian" /> </xs:restriction> </xs:simpleType> </xs:element> </xs:sequence> </xs:complexType> . <xs:complexType name="FrotzModel"> <xs:complexContent> <xs:extension base="midas:Model"> </xs:extension> </xs:complexContent> </xs:complexType> . . . </xs:schema> etc. I validate, compile, and jar up the XSD using XMLBeans. No problem. I then do something like this: FrotzModel blorb = FrotzModel.Factory.newInstance(); blorb.setID("model id"); blorb.setType(Model.Type.STATISTICAL); At this point, a printout of the XML structure displays the following: <mida:Type>Statistical</mida:Type> </xml-fragment> Somehow, XMLBeans thinks "midas" is the plural of "mida" and has helpfully dropped the S since I only have one of them. But that's not what I want! Our suite of programs depends on the namespaces being propagated correctly, and "mida" clearly does not equal "midas", resulting in a failed parse of the XML. I am earnestly hoping that this is a simple configuration option that I am just not aware of; I would find it very surprising if this were a bug. I am basically a beginner at XSD schemas, so it is entirely possible I missed something. Nevertheless, it is a show-stopper preventing me from making forward progress. I have searched Google, the XMLBeans FAQ, and the mailing list but have not found anything useful. I am hopeful that this list will provide me with enlightenment. :) Thanks, Justin **************************************************************************************The contents of this e-mail message and any attachments are confidential and are intended solely for the addressee.
