Help with Soap XML response and Schema

Hi,

I am an Oracle DBA and not a developer but I have been trying to expose an Oracle function as a webservice using Jdeveloper and it works..sort of. Jdeveloper builds all the components and upon testing I get the correct answer back but the xml returned isnt seen as xml and so characters are changed I.E < becomes &t etc.

The webservice treats it as a string. I have read elsewhere that I need to define the response XML schema which I've done but still don't get the response I'm looking for (XML unescaped)

I am hoping someone can see an error in my wsdl or xsd or point me in the direction of an article that would help. Thank you
