[udig-users] Problem executing process

[BrianRook <brook@xxxxxxxxxx>]

I'm trying to run a process and I've got a real simple one that returns the
input value (echo)  Here is the process description from uDig:

<xml-fragment statusSupported="false" storeSupported="false"
wps:processVersion="1" xmlns:ows="http://www.opengis.net/ows/1.1";
xmlns:wps="http://www.opengis.net/wps/1.0.0";
xmlns:xlink="http://www.w3.org/1999/xlink";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
  <ows:Identifier>com.ittvis.wps.Echo</ows:Identifier>
  <ows:Title>Echo</ows:Title>
  <ows:Abstract>Returns the input</ows:Abstract>
  <!--<ows:Metadata xlink:title="spatial" />-->
  <DataInputs>
    <Input maxOccurs="1" minOccurs="1">
      <ows:Identifier>INPUT_STRING</ows:Identifier>
      <ows:Title>Input String</ows:Title>
      <ows:Abstract>String to input</ows:Abstract>
      <LiteralData>
        <ows:DataType ows:reference="xs:string"/>
      </LiteralData>
    </Input>
  </DataInputs>
  <ProcessOutputs>
    <Output>
      <ows:Identifier>OUTPUT_STRING</ows:Identifier>
      <ows:Title>Output String</ows:Title>
      <ows:Abstract>String to return</ows:Abstract>
      <LiteralData>
        <ows:DataType ows:reference="xs:string"/>
      </LiteralData>
    </Output>
  </ProcessOutputs>
</xml-fragment>

However, on the next screen in uDig when I put in the input string and hit
next, I get this error:
"Unable to recognize service, choose another".  When I click on that message
I get an error box that says java.lang.String cannot be cast to
net.refractions.udig.catalog.IResolve.

Could you help me understand what this error means?
