I created a WSDL for an EJB, for it to be used as a WebService. I used the SOAP/HTTP protocol.
Now, what I understand ( I am a newbie to WebServices), that the endpoint for the WebService is the Remote Interface of the bean. That is, if I have a bean named myPackage.Sample and the various bean classes as:
Supply the Component Interface (implementing javax.ejb.EJBObject; note that this will automatically implement javax.rmi.Remote. Theoretically a component interface could serve as an endpoint interface)
Supply the Home Interface (implementing javax.ejb.EJBHome)
Expose as a local stateless session bean:
Supply the Local Component Interface (implementing javax.ejb.EJBLocalObject)
Supply the Local Home Interface (implementing javax.ejb.EJBLocalHome)
I am using WSAD v5.1 to create the WebServices out of an EJB. And I am not able to set the Local Interface of my bean as the SEI for the WebService.
Also, using the IDE to create my WebServices, a whole bunch of files are created (eg: webservices.xml, webservicesclient.xml, etc). Though I know and have understaood what these files individually stand for, what I have not been able to relate is how all these components come together when a client initiates a request to the WebService.
Pardon me if this questions sounds very basic but I am new to the WebServices world. Using IDE, though reduces the work during development time, it really has not helped me to understand the concept of WebServices as a whole and the exact path of execution when a client calls a WebService using SOAP/HTTP.
Any pointers in this directions would be of great help (books, documents, etc).

A good IDE doesn�t necessarily help you learn a new area, but it should increase the productivity of the developer that is already competent in that area � this is a point that seems to be lost on some people. There are many technical endeavors that are much easier learned by getting your hands dirty � at least initially, and in my personal opinion Web Services is one of them. It doesn�t help that each vendor puts their own spin on things by changing deployment descriptor names, filenames, etc. from what they are in the initial specifications.
