Dynamic Partnerlink with WSIF HTTP Binding

Question

Hi,
I have been trying to change the endpoint location details of my HTTP Binding Partnerlink during runtime / deploy-time. AFAIK, there are two ways to do this.
1. Deployment Descriptor : Change the "location" property in bpel.xml to point to a different location. Ideally this can be done at deployment using ant or use the Java APIs to change them during runtime. This works for partnerlinks which use a SOAP Binding, but does not work for HTTP Get/Post Bindings.
2. Using WS-Addressing : Again this works with a SOAP WSDL, but no go with HTTP GET/POST WSDLs.
Has anybody been able to get dynamic partnerlinks working for non SOAP Partnerlinks?

Answer 1

I get a collection of endpoint url and have created a single dummy WSDL and invoked in a parallel flow within a scope.
I have created partner reference variable, input and out variable for the service within the scope.
You can find the code snippet below.
<bpelx:flowN name="FlowN_1"
N="count(bpws:getVariableData('UserUpdateRoutingService_OutputVariable','payload','/ns9:UserUpdateProviderInfoCollection/ns9:UserUpdateProviderInfo'))"
indexVariable="flowIndex">
<sequence name="Sequence_1">
<scope name="Scope_1">
<variables>
<variable name="InvokeEnterprisePingService_pingUserBySmsId_InputVariable"
messageType="ns5:EnterprisePingServiceRequestMessage"/>
<variable name="InvokeEnterprisePingService_pingUserBySmsId_OutputVariable"
messageType="ns5:EnterprisePingServiceResponseMessage"/>
<variable name="partnerReference"
element="wsa:EndpointReference"/>
</variables>
<sequence name="Sequence_2">
<assign name="ClearEndpointEnterprisePingService">
<copy>

<to variable="partnerReference"
query="/ns7:EndpointReference/ns7:Address"/>
</copy>
</assign>
<assign name="DoPartnerlinkEnterprisePingService">
