I am pleased to announce an experimental release of GCJNI. GCJNI is a library that allows Haskell to invoke Java code via the Java Native Interface (JNI). The implementation uses GreenCard to make the JNI (a C language interface) available to Haskell. GCJNI includes a few convenient features, such as: - Integration of the Haskell and Java garbage collectors, so that Java objects are garbage collected when they are no longer accessible from Haskell. - Type class based overloading, which makes it easy to pass common types (like Int, Float and String) to or from Java code. - A tool (GenBindings) which uses Java reflection on a set of compiled Java classes to generate a Haskell module with a simple, high-level, type-safe interface to the underlying Java code. GCJNI has been succesfully tested using both hugs98 and ghc under both Linux and Windows. Binary distributions are provided for all for of these (compiler, platform) combinations. More information (including pointers to the relevant distributions) is available from the GCJNI web page at: http://www.haskell.org/gcjni Bug reports and feedback should be sent to antony@apocalypse.org Enjoy! -- Antony Courtney Grad.
