Returning Handmade XML from a Simple EJB

Question

I've create an EJB in Eclipse with a method that returns String.

The String is an XML fragment made from a DOM Document.

When I invoke the EJB as a web service, the String is correct, but it gets CDATA tags added around it. How can I avoid this and get the raw XML in there, directly, instead?

Thank you

@WebService(serviceName = "XService", portName = "XPort", targetNamespace = "http://here.com/x/ejb")
@Stateless(name = "X", mappedName = "ejb/XJNDI")
@SOAPBinding
   (
     style = SOAPBinding.Style.DOCUMENT,
     use = SOAPBinding.Use.LITERAL,
     parameterStyle = SOAPBinding.ParameterStyle.BARE
    )
public class XEJB implements X
{

public String complex(int input) { // builds and returns some XML as a String } }
