Does anyone performancewise which one is better either a StatelessSessionBean or a webservice? My Client and the service which I am going to expose will be implemented only on java. So which one would be faster? One thing about webservice is that it has to convert the xml object to java and vice versa which I think is unnesscary if you are sure that the client which gonna call this service would be in java. So i think a statelessssessionbean would be faster that a webservice. Also I'll get instance pooling with Beans.

RMI would be a lot more efficient performance wise than either SOAP or REST web services.
