Java Method Servers: The Basics

Java method servers are software components that allow Java objects to invoke methods on remote objects residing on different JVMs. They provide a transparent mechanism for distributed method invocation, abstracting the complexities of network communication and object serialization.

Key Features of Java Method Servers

• Remote Method Invocation (RMI): Java method servers implement the Java RMI specification, which defines a standard protocol for remote method invocation.
• Object Serialization: Method servers serialize objects passed as arguments or return values, enabling them to be transmitted over the network.
• Security: Method servers support various security mechanisms, such as authentication, authorization, and data encryption, to ensure secure communication.
• Load Balancing and Fault Tolerance: Method servers can be deployed in a clustered environment, providing load balancing and fault tolerance to handle high traffic and server failures.
