Hello All I would like to know which is a better solution for the case in which I would like to send user details from a java application(Application A) to another one(Application B) residing in a different server(Tomcat) and get a response(whether the user details are valid). Application A will be used by many other applications for checking user details. I would like to know whether I should go for an RMI solution in which one application will be a RMI Client and the other,Server. On the other hand, I feel that Servlet as Application A will perform far better as I can use Http connection to connect to Application B and get a response of the user validity instead of using RMI. Could someone please help me on this to choose the right solution ? Thanks in advance Ragavan
