What are the functions and features of the Java RPC framework?

The Java RPC framework is a framework used for implementing remote procedure calls, allowing communication and remote method invocation between different Java applications. Its features and characteristics include:

1. Achieving remote procedure calls: Java RPC framework enables remote procedure calls, allowing different Java applications to communicate and call remote methods over the network.
2. Support for multiple transport protocols: Java RPC frameworks typically support a variety of transport protocols, such as HTTP and TCP, in order to facilitate communication in different network environments.
3. Serialization and deserialization: Java RPC frameworks typically handle the serialization and deserialization of objects automatically, allowing data to be transferred between different Java applications.
4. Load balancing and fault tolerance mechanisms: Java RPC frameworks typically offer load balancing and fault tolerance mechanisms to ensure system reliability and high availability.
5. Easy to integrate and use: Java RPC frameworks typically offer simple and user-friendly APIs and documentation, allowing developers to quickly integrate and use the framework.
6. Performance optimization: Java RPC frameworks often undergo performance tuning to ensure efficiency and speed of remote calls.
