CamlJava - an OCaml/Java interface ================================== DESCRIPTION: This is a very preliminary release of CamlJava, an OCaml/Java interface based on the following schema: Caml/C interface JNI (Java Native Interface) Caml <------------------> C <-----------------------------> Java Currently, CamlJava provides a low-level, weakly-typed OCaml interface very similar to the JNI. Java object references are mapped to an abstract type, and various JNI-like operations are provided to allow Java method invocation, field access, and more. A basic callback facility (allowing Java code to invoke methods on Caml objects) is also provided, although some stub Java code must be written by hand. In the future, a higher-level, strongly-typed interface will be provided, whereas Java classes are mapped directly to Caml classes. This raises fairly delicate type mapping issues, though, so don't hold your breath. REQUIREMENTS: - This release of CamlJava requires Objective Caml version 3.08 or later. - A Java implementation that supports JNI (Java Native Interface). So far, only Sun's JDK has been tested. INSTALLATION ON A UNIX PLATFORM: - Edit Makefile.config to define parameters depending on your Java installation. As distributed, the library is set up for Sun's JDK version 1.4.1 on a Linux x86 platform. - make become superuser make install - For testing: make tst INSTALLATION ON A WINDOWS PLATFORM: - Works with the MSVC port of OCaml for Windows. GNU make and Cygwin tools are required to do the installation. - Edit Makefile.config.msvc to define parameters depending on your Java installation. - make -f Makefile.msvc make -f Makefile.msvc install - For testing: make -f Makefile.msvc tst USAGE: The module is named "Jni". A good knowledge of the JNI is assumed; see Sun's JNI book or http://java.sun.com/products/jdk/1.2/docs/guide/jni/ Then, the comments in lib/jni.mli should make sense. Usage: ocamlc -I +camljava jni.cma ... or ocamlopt -I +camljava jni.cmxa ... See the programs in test/ for examples of use. LICENSE: GNU Library General Public License version 2.
