Consuming WCF service from Oracle

When you get a Http 500 error it is normally an internal error. For example that the developer is calling your service without setting all the input values, your code could then generate a divide by zero error, which when not caught is returned to the client as a http 500 error.

You can configure the soap version of a WCF service to be the same as an asmx service.

If you are getting response 500 (internal error) from WCF service, try set in web.config of WCF service includeexceptiondetailinfaults=true .(http://msdn.microsoft.com/cs-cz/library/system.servicemodel.description.servicedebugbehavior.includeexceptiondetailinfaults(v=vs.110).aspx)

Then you will get detailed exception (wrong soap action, wrong format...)

Call WCF service from PL/SQL.

utl_http but it works.
