What you're describing is referred to as a "bean" in Java terminology. These can range from simple ad hoc ones implemented for one specific sharing need to full-blown Enterprise Java Beans as defined in the Java EE spec. EJBs are supported by full application servers such as JBoss, but not by streamlined servlet containers like Tomcat. There are various open source packages that can be added to Tomcat to provide support for beans if you want to use them (GIYF). The RMI mechanism espoused by Leon R is a formalized remote procedure call implementation built into the JRE. When the caller and callee are inside the same machine, the overhead is quite low but still involves object serialization and loopback TCP/IP traffic. Whether or not that's a concern depends on how much data you push across the interface.
