What's merit and demerit of Socket Connection?

thanks

You can drop in an RMI connection fairly transparently, but with agonizingly little control. Implementing a socket connection gives you all the power but a lot more things that might go wrong.

Advantages of sockets:

Can be more efficient and scalable than RMI (if good implemented).

You have control on how to handle concurrent clients; You can make it simple or complex as your requirements.

You don’t have to worry about extra work came with RMI, like registering RMI server, and working with firewalls.

Advantages of RMI

In Designing, RMI more close to Object oriented than sockets.

It is simpler in coding, and you don’t have to worry about thread pooling.

You have to choose RMI or a socket, depending on what is best for your project (from your point of view).

For example being the socket more efficient may not be important since number of users connecting to system is very small.

So it is not a matter of how many points you can find in favor or against socket, but what is more suitable for your project.
