What does RMI do/not do?

Hi all,

I understand, from reading various literatures, that RMI enables a java object's methods to be called by some remote host.

What I wanted to know was does RMI provide any other types of services such as transaction management, security etc?

No - rmi pretty much only provides remote access, and distributed garbage collection.

For anything else, you're going to either have to code it yourself, or use a technology that adds these things to RMI.

For example, EJB technology uses RMI, but provides additional security, transaction management, etc.

Jini is another example of a technology that at the base uses RMI, but adds other functionality.
