No Serializer found to serialize a 'org.w3c.dom.Element' - Web Services

[Amrita Chawla]

Hi
I am trying to run a method exposed as a web service in JDeveloper. This method should return Element type. However, it gives me the following error:

Servlet error: No Serializer found to serialize a 'org.w3c.dom.Element' using encoding style 'http://schemas.xmlsoap.org/soap/encoding/'.

Has anyone encountered the same error... have a say on it?

This usually has to do with registering complex type mappings.
If this is a user defined type try out

 SOAPMappingRegistry smr = new SOAPMappingRegistry();
smr.mapTypes(...)  

this should resolve it.
