Issue I faced with RPC style wsdl

Last week I was given a synchronous wsdl and asked to develop a sync-sync interface (SOAP-Proxy). I imported it in ESR, developed the interface and was all set to test.

I opened SOAP UI, imported the wsdl and started mock service. Triggered proxy message from ECC.

And boom –

HTTP 500 Internal Server Error


Then I revisited all the configurations, felt everything is fine. Retested the scenario. And again – 500 exception

I tried to get the logs from SOAP UI. Found the below error:

ERROR: An error occured [Missing operation for soapAction [] and body element……


I’ve set Require SOAP Action property to ‘False’ in SOAP UI and tested. – Same issue again.

I was wondering where could be error. When I investigated the wsdl I found that SOAP binding was Remote Procedure Call (RPC) style. Generally, we use document style binding.

In external definitions in ESR when we import a wsdl, by default Messages option will be set to “From All Available Message Definitions”

But, when we import wsdl with RPC style binding, we have to change it to “Using RPC Style”.

Finally, when I made these changes, my scenario was successful.
