Features Automatic mapping from Java to native functions, with simple mappings for all primitive data types Runs on most platforms which support Java Automatic conversion between C and Java strings, with customizable encoding/decoding Structure and Union arguments/return values, by reference and by value Function Pointers, (callbacks from native code to Java) as arguments and/or members of a struct Auto-generated Java proxies for native function pointers By-reference (pointer-to-type) arguments Java array and NIO Buffer arguments (primitive types and pointers) as pointer-to-buffer Nested structures and arrays Wide (wchar_t-based) strings Native long support (32- or 64-bit as appropriate) Demo applications/examples Supported on 1.4 or later JVMs, including JavaME (earlier VMs may work with stubbed NIO support) Customizable marshalling/unmarshalling (argument and return value conversions) Customizable mapping from Java method to native function name, and customizable invocation to simulate C preprocessor function macros Support for automatic Windows ASCII/UNICODE function mappings Varargs support Type-safety for native pointers VM crash protection (optional) Optimized direct mapping for high-performance applications. COM support for early and late binding. COM/Typelib java code generator. Community and Support All questions should be posted to the jna-users Google group. Issues can be submitted here on Github. When posting to the mailing list, please include the following: What OS/CPU/architecture you're using (e.g. Windows 7 64-bit) Reference to your native interface definitions (i.e. C headers), if available The JNA mapping you're trying to use VM crash logs, if any Example native usage, and your attempted Java usage It's nearly impossible to indicate proper Java usage when there's no native reference to work from.

Fork the code from https://github.com/java-native-access/jna and submit pull requests. For more information on setting up a development environment see Contributing to JNA. If you are interested in paid support, feel free to say so on the jna-users mailing list. Most simple questions will be answered on the list, but more complicated work, new features or target platforms can be negotiated with any of the JNA developers (this is how several of JNA's features came into being). You may even encounter other users with the same need and be able to cost share the new development.
