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

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.
JNAerator Studio
While JNAerator is mainly a command-line-based tool, it also contains a limited GUI that's ideal for simple quick generation experiments.
It can be launched from the Web using the direct WebStart link from the project's main page, or by double-clicking on JNAerator's JAR executable archive.
