Problem accessing JDev Generated Web Service on PL/SQL Package

Question

Hi,
I'v generated a web service from a pl package using the wizard in JDev for use with Adobe Flex builder. Adobe says they support two types of web services, WSDL 1.1 RPC-Encoded and Document-literal. When I create the web service as Document literal, I am able to consume the web service without errors, however, adobe cannot parse the xml because of the namespace tags. I then created an RPC-encoded type of webservice but then when I run my Flex application, it gives following error:
[WSDLError faultString="Type tns1:text_xml not resolvable" faultCode="WSDL.BadType" faultDetail="null"]
     at mx.rpc.soap::WSDLParser/http://www.adobe.com/2006/flex/mx/internal::parseMessage()
     at mx.rpc.soap::WSDLOperation/parseMessages()
     at mx.rpc.soap::Operation/http://www.adobe.com/2006/flex/mx/internal::invokePendingCall()
     at mx.rpc.soap::Operation/send()
     at Function/http://adobe.com/AS3/2006/builtin::apply()
     at mx.rpc.soap.mxml::Operation/send()
     at SandBox/__btnGetEmployees_click()
It seems that it does not like either something in the encoded message or the WSDL. Below is my WSDL:

I'm not a XML or Web Service guru, so I hope somebody out there has had similar or can help bridge the gap of my Web Service ignorance.
Thanks

There are samples and more information on calling Web services from the database here:
