👉 RJ computing, or Remote-Java Computing, is a framework that allows Java applications to run on remote servers without the need for traditional remote method invocation (RMI) or Java Server Faces (JSF). Instead, it leverages the Java Native Interface (JNI) to call native code written in languages like C or C++ directly from Java, enabling seamless integration of Java with low-level system resources and services. This approach provides a more flexible and efficient way to build distributed applications, as it bypasses the overhead of Java's virtual machine and allows for better performance and resource management. RJ computing is particularly useful in scenarios where Java applications need to interact with native libraries or services, such as in high-performance computing, embedded systems, or microservices architectures.
