JNAerator

JNAerator is a computer programming tool for the Java programming language which automatically generates the Java Native Access (JNA) or BridJ code needed to call C, C++ and Objective-C libraries from Java code.

It reads in ANSI C header files and emits Java code. Some optional customization can be done through command line options, which can be saved in configuration files.

JNAerator does not need any native compiling beyond that of the targeted dynamic library (all of the glue code is in Java), which helps simplify the process of binding Java to C native libraries when compared to Java Native Interface (JNI)-based means.

Its output is typically larger and harder to use than hand-crafted JNA bindings, but it saves time and effort for bindings of large libraries with JNA.
