Hello everybody,
I am developing a project that consists of creating an editor component inside of an J2EE environment (essentially a servlet) which allows to edit a diagram with a standard web browser by communicating with the web component on the server. The project will require Java and servlet programming on a Tomcat server.

When I started I didn't know a lot about this field and I began to develop the application in the following manner:the diagram editing in realized by the web client side using an applet, and I intend to use applet servlet communication for getting to the final requirements. Do you have any advice about what method should I use, RMI maybe? Are there any examples that I could use?
Thank you in advance
