Hello,

After hours on a non working example using JPA, JDO, Spring ORM and more, I
went to a more simple example but even this isn't working.

I'm trying JDO (in order to let in work with oracle later) with a quite
simple XML file and it's XML Schemas.
The first step I would like to achieve is generating the descriptors of the
files.

Enclosed are the XML, the XML Schemas and the corresponding Java file I try
to use.

At the execution, I get the following Java exception :

No namespace declaration has been found for person
* assuming default namespace of http://www.w3.org/2001/XMLSchema
<person> elements are either currently unsupported or non-valid schema
elements.
Exception in thread "main" java.lang.NullPointerException

Could someone help me understand this exception ?

Jorrit Wortel
