Hi Heikki, I had a similar problem: http://www.mail-archive.com/[email protected]/msg03316.html
... which we solved like this: http://www.mail-archive.com/[email protected]/msg03319.html So basically, we don't have the schema resources in the context classloader and load them explicitly. Write me a private mail, if you want to have the source code of our XmlBeanFactory.

I'm getting a similar problem but using newIstance instead of parse. Here is my code: <code> SchemaTypeLoader stl = XmlBeans.typeLoaderUnion( new SchemaTypeLoader[] { x.y.MyPrefixEventNameDocument.type.getTypeSystem(), XmlBeans.getContextTypeLoader()} ) ; SchemaType st = stl.findDocumentType(new QName("","EventName","MyPrefix")); //I don't use namespace EventName evt = (MyPrefixEventNameDocument)stl.newInstance(st, null); </code> The problem is that I have another class a.b.AnotherPrefixEventNameDocument (same root element in 2 XML buffers), so I'm getting this exception: java.lang.ClassCastException: a.b.impl.AnotherPrefixEventNameDocumentImpl Can you help please?? (I'd like to avoid using namespaces if possible :) ) Said Radu Preotiuc-Pietro wrote: > > Heikki, > You seem to have a good understanding of the issue.
