All right it works. I did misundestund about container element. After removing it all works fine. Thank you very much. As you see the result is very clean. Only two files and POJO does not have any dependencies on Castor. Very nice. I think you can place this example to the Cator site to provide simple Hierarchy functionality.
Would you mind - given the time I have spent on helping you - coming up with a well-structured HOW-TO document for the XML part of Castor ?

It won't work in your case, and switching to the use of the location attribute is the correct way forward. Regards Werner Werner Guttmann wrote:Hi Antoni, looking at the missing namespace prefix on the children element, I changed the mapping as follows (and introduced a location attribute on the <bind-xml> definition for the children field mapping. That did it for me.<mapping> <class name="xml.children.Foo" auto-complete="false"> <map-to xml="foo" ns-uri="http://example.com/foo"; ns-prefix="foo"/> <field name="name" type="java.lang.String"> <bind-xml name="name" node="attribute" /> </field> <field name="children" collection="collection" type="xml.children.Foo"> <bind-xml name="foo" location="children" /> </field> </class> </mapping> I will have another look at the use of the container attribute, as it looks like a bug to me .... but I think that the solution shown should satisfy you.

Enstead of one domain class I get six classes. From simple 20line class I get something too complex.As I mentioned before I want to use same domain structure independent from the technologies. In the other words nohibernate, castor or axis should be present in the model. Of course here can be three different domain models, one is my own, second generated by castor, third database layer model. But it requers mappings between models and is not what we are looking.The ideal is something like castors mapping file. It's a glue between java class and xsd schema. Only thing is to get it workin every situation. Regards.
