SOAP client bridge sample

This example illustrates how to use a Java-based DFC/SOAP bridge that runs as an e-Biz Impact plug-in to a create a bridge from an ODL DFC client to a SOAP-based service. The ODL client calls the bridge through DFC links, and the bridge in turn calls the SOAP service.

Four different DFC functions are implemented within the bridge and defined within the cluster:

soapHellol – demonstrates the ArgumentsInterface method of DFC argument handling.
soapHello2 – demonstrates the DfcMessage method of DFC argument handling in conjunction with static SOAP stub bindings.
soapHello3 – demonstrates the DfcMessage method of DFC argument handling in conjunction with dynamic SOAP bindings.
soapHello4 – defined as a valid DFC in a cluster, but unimplemented in the bridge plug-in.
