Deploying processes to Apache Ode

[Anup Chandran <an...@3ds.com>]

I was trying to invoke the process that i successfully deployed on ODE.

The WSDL definition is :

<?xml version="1.0"?>
<definitions name="HelloWorld"
        targetNamespace="http://sample.bpel.org/bpel/sample"
        xmlns:tns="http://sample.bpel.org/bpel/sample"

        xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
        xmlns="http://schemas.xmlsoap.org/wsdl/"
        >

     output to the BPEL Process. But you can define or import any XML 
     Schema type and us them as part of the message types.

</definitions>


The soap message / request is :

<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
  <!-- test soap message -->
  <SOAP-ENV:Body>
    <ns1:initiate xmlns:ns1="http://ode/bpel/unit-test.wsdl">
        <input>Hello</input>
    </ns1:initiate>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>


This is the error :

Any ideas what is happening? initiate is declared in the wsdl.
