BPEL process with http-POST service doesn't work

Question

Hi OraclePM community,
i tried to test a http-POST service. The message i wanted to send is very simple:
<?xml version="1.0" encoding="UTF-8"?>
<GetFeature service="WFS">
<Query typeName="states"/>
</GetFeature>
In the POST-service wsdl:types/xsd:schema i created this new element to ingest the request-xml:
<xsd:element name="GetFeature">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="Query"/>
</xsd:sequence>
<xsd:attribute name="service" use="required" type="xsd:string"/>
</xsd:complexType>
</xsd:element>
<xsd:element name="Query">
<xsd:complexType>
<xsd:attribute name="typeName" use="required" type="xsd:string"/>
</xsd:complexType>
</xsd:element>
I made the same in the bpel-service wsdl for input-variable definition. When i deployed the bpel process and went to the automatically generated client then i had only two input-boxes. One box to type in the 'service' (which is signed as string) and another box to type in the 'Query' (which is signed as anyType). But thats a wrong interpretation of my wsdl. I should type in the 'typeName' which is also a string. Therefore i get an exception at the invoke: "Argument 'GetFeatureIn' is not compatible".
O.K. i tried something different: In the client i din't choose the option 'html-form' but the option 'xml-source' and copied the request-xml in there. The result was another exception earlier (the first assign after the receive). The exception is: "error in evaluate <from>-expression in line "33". The result for the XPath-expression "/client:GetFeature" is empty"
Can anybody help me?
Kind regards

Answer 1

sure you send the right xml?
what I would try is to copy the xml from the receive, paste and extend it, and see if this works . . these errors are mostly because of no namespace defined or such ..
sure your element has the right namespace?

2)
here is the xml for the following schema ..
XML
<ns1:AttributetestProcessRequest xmlns:ns1="http://xmlns.oracle.com/Attributetest">
<ns1:input/>
</ns1:AttributetestProcessRequest>
schema
schema attributeFormDefault="unqualified"
     elementFormDefault="qualified"
     targetNamespace="http://xmlns.oracle.com/Attributetest"
     xmlns="http://www.w3.org/2001/XMLSchema">
     <element name="AttributetestProcessRequest">
          <complexType>
               <sequence>
                    <element name="input" type="string"/>
               </sequence>
<attribute name="service" use="required" type="string"/>
          </complexType>
     </element>
     <element name="AttributetestProcessResponse">
          <complexType>
               <sequence>
                    <element name="result" type="string"/>
               </sequence>
          </complexType>
     </element>
</schema>
it works design and runtime in 10.1.3.1
