When you create a OSB HTTP service, no war is deployed to WebLogic.
The kernelEar application contains a WebCreatorModuleFactory which - through a WebCreatorModule - will register you endpoint to a dummy httpTransport.war web application - this httpTransport.war is strictly empty.
In the deployment monitoring page, you will see all these endpoints as sources by httpTransport.war:
The internal implementation of a HTTP service is based on a weblogic.servlet.internal.WebAppModule
