Problem running Web Service that uses OracleXMLSave on Oracle AS 10.1.3

Question

I am trying to deploy a Web Service that uses OracleXMLSave. The service was built in Jdeveloper 10.1.3 and is deployed to 10gR3 AS. I have all the utitlites available from the 10g Production XML Developers Kit installed . The code compiles and generates correctly . I then deploy to an EAR file that inlcudes the applicaiton code and also all the XDK libraries . No problems so far. But when I run the app, I get an exception like the one below. It says it can't find XMLType . The funny thing is that this library (xdb.jar) and all other related libraries are there in the EAR file . In fact the class loader seems to see it because the exception says that it is there (see text below).
I have added all the libraries from XML Developer kit like xdb.jar , xsu12.jar , etc. I have also verfieid that the files are selected in the WebServices.deploy file and also present in the EAR file . (See full list below the eror message below. ).
It looks like for some reason the class loader can't load the class even though it seems to know that the class exists in the path.
Been sweating on this for a while (probably staring it at too long :) and would really appreciate some help.
This is the exception thrown when the OracleXMLSave Class is called for the first time.

Answer 1

Well I got the EJB lookup working but only when I changed the Provider Url to the pre-10.1.3 format e.g. ormi://someserver:12421/someapp and used jazn.com/oc4jadmin as the username. After reading the online documentation, I didn't think this should work!
Another issue I am having is casting a datasource returned from a JNDI lookup for a datasource. We used to do the lookup in the code and cast to an OracleDataSource. Now it is throwing a class cast exception to ManagedDataSource. Is there a quick and easy solution to this? I really don't want to have to go into the code and change this cast so it'd be great if we can get this working without changing code. This code has been working in a prod environment for two years now on 9.0.3 -> 9.0.4...
