Evaluating the Java Native Interface JNI: Leveraging Existing Native Code, Libraries and Threads to a Running Java Virtual Machine

AbstractThis article aims to explore JNI features and to discover fundamental operations of the Java programming language, such as arrays, objects, classes, threads and exception handling, and to illustrate these by using various algorithms and code samples. The authors also investigate the JNI Invocation API that allows native applications to interact with the Java Virtual Machine JVM. They focus on attaching native threads to a running JVM and on leveraging existing native code using one-to-one mapping and shared stubs.
