ODE and SOAP Headers
Hi
I have a problem with the use of SOAP headers.
I want to implement a BPEL process that receives
a message, adds a SOAP Header and passes it to a
second web service.
The wsdl for the bpel process has not a header binding
since it is not required.
The wsdl for the second process has a header binding
<wsdl:message name="CachePairRequest">
<wsdl:part name="parameters" element="tns:CachePair"/>
<wsdl:part name="cacheID" element="tns:CacheID"/>
</wsdl:message>
<wsdl:operation name="CachePair">
<soap:operation soapAction="http://www.stark.org/Cache/CachePair"
style="document"/>
<wsdl:input>
<soap:header message="tns:CachePairRequest" part="cacheID" use="literal"/>
<soap:body message="tns:CachePairRequest" parts="parameters" use="literal"/>
</wsdl:input>
</wsdl:operation>
I believe that the wsdl is correct. I use the JDK 6 wsimport tool
and the generated client code correctly handles the SOAP header.
The bpel snippet for the header is
<assign>
<copy>
<from><literal>
<CacheID xmlns="http://www.stark.org/Cache">BADC0C0A</CacheID>
</literal></from>
<to>$CacheRequest.cacheID</to>
</copy>
</assign>
However when i run it, an error message is logged

It seems that the message generated by ODE is invalid.
The assignment passes without errors. If for example
i enter a non-existent part like cacheIDAAAA then an
error message is displayed during deployment.
Also if i change the wsdl to
<soap:body message="tns:CachePairRequest" parts="parameters cacheID"
use="literal"/>
and remove the header binding
then the CacheID element is correctly appended to the SOAP Body.
I tested against both ODE 1.2 and 1.3.2 running on tomcat 6.0.18
and the problem remains.
Can anyone provide an example of correct SOAP Header usage or
give me some hints to find the error?
Thanks in advance

Have you looked at this?
http://ode.apache.org/headers-handling.html
The section about dynamic headers in particular might help.
