what is the difference between java E beans and RMI ?
Hello
I have to develop a program that allow the users to have access to the Patient information . The program will also organize appointment between the users and the patients. + extra thing like agenda .....
I will have about 10 to 20 user that will have access at the same time to the same info .
My question is :what is the best solution for such kind of programes
RMI :after searching in google (it is light weight )
java beans:more powerful than RMI
or maybe thread ?
any one can explain the difference please ?
Thank you
What does java E beans stand for? You mean Enterprise Java Bean(EJB)?
I know about EJB.
I think EJB using the techniques of RMI.
If you design to use EJB, you have to config free Application Server like JBoss or Expensive Application Server like Websphere.
The link for RMI.
http://java.sun.com/docs/books/tutorial/rmi/overview.html. EJB may have more concepts than RMI.
Are you familiar with Java? 10 to 20 users is not a big number. Even simple Javabeans(not EJB) can handle it. If you are beginner in Java, I would recommend simple Javabeans, servlet and JSP.
EJB involving many client side and server side object.
If you use EJB, you have to learn the concept first. The newest version of EJB is 3.0. I would recommend EJB 2.0 to you. The book "Mastering EJB" is good and it is free on some website.
You can also download the J2EE example from sun and try it on J2EE 1.4 server.
I have experienced in J2EE 1.4 application server, weblogic and websphere server.
thank you for your help

yes I mean EJB

I dont know if i have to say yes .I developed many swing applications with a data access to postgresql

It is a swing application

the reason why i want to use EJB or RMI ,is the multi access at the same time
ex : of one of my Patient swing windows
First Name last namestatus
jackBaker sick
XY ok
so all the users will see this information
any user can change the status of the Patient .Other users must see the changes directly
