[JAXB 2.0] Unmarshalling error if the XML contains w3c.Element nodes

Question

Hi!
I'm using the JAXB 2.0 library to create an XML file according to a XML Schema (XSD).
I use the JAXB 2.0 classes, that I have previuosly generated, to fill the data and finally I execute the marshal method to store a XML file with the object's info.
The second step is unmarshalling the file. Alright in my first attempt: I get all the JAXB objects filled with the data of the file.
Now I try to add w3c.dom.Element nodes underneath a JAXB object that accepts a list of w3c.dom.Elements:
org.w3c.dom.Element cip = (org.w3c.dom.Element) doc.createElement("CIP");
root.appendChild(cip);
t = doc.createTextNode("CIP");
t.setData("TEST");
cip.appendChild(t);
qpd3.getAny().add(cip);
And the resulting XML file is marshalled correctly again. Moreover, the node QPD contains a list of simple nodes like 'CIP' (the w3c.dom.Element of the example).
The second step, to try unmarshalling the XML file I just have generated:
Using a main method in my class the file is unmarshalled with no problems.
It's now, when I deploy the web service that calls the unmarshall method (sending the same XML file to the same function), I receive a parsing error!!
2007-01-30 20:00:08.221 ERROR caught exception while handling request: java.lang.IllegalAccessError: void oracle.xml.parser.schema.XSDNode.<init>()
Why does this error appear??? I supose JDeveloper tries to parser the w3c.dom.Element nodes like a XSDNode and therefore it fails (what is a XSDNode...?). But if I execute the same method from the "main" of my class it works! Maybe the problem is related with the libraries that OC4J loads when it starts...
Can anyone help me?? Thanks in advance!

Hi Blaise,
The Document class I use to generate the w3c.dom.Element nodes in the marshaling procedure belongs to oracle.xml.parser.v2.XMLDocument class. And it is located in the jar file: file:/C:/Oracle/jdeveloper/jdk/jre/lib/rt.jar!/org/w3c/dom/Document.class
I have also checked if the unmarshal method of my class has linked the same library, althought is not used in the unmarshalling process (but maybe is implicit...) and it's OK.
Have you seen something wrong?
Thank you!
