java4cpp-sample

Demonstrate java4cpp capabilities.

Gets full informations directly on the java4cpp-core page project.

Instalation

1. Download a copy of the project from git.
2. Generate proxies: type mvn install in the root directory.
3. Open the Xcode 5 project inside macosx directory or Visual Studio 10 project inside win32 directory.
4. Sets the JRE path in cpp/main.cpp
5. Build and Run !

Prerequisite

• Mac OS X with Xcode 5 or later / Windows with Visual Studio 10 or later
• A Java installation (JRE or JDK, 1.6 minimum)
• Maven command line tools (and internet connection)

Other platform

Adding other platform is very easy, it is just necessary to add to your favorite IDE or build process all the files inside cpp folder, gives a valid jni.h files for your platform and modifiy main.cpp to enter a valid path to your installed JRE or JDK.

How It Works

This project contains two parts :

1. A Java parts that define some classes that we want to use in the C++ parts.
2. A C++ parts that use the proxies class to demonstrate some functionnalities:

• Instanciation of Java object
• Calling methods
• Managing hierarchie of classes
• Deal with enums and arrays
• Translation of Java exception as regular C++ exception
• Multi-threadings environment
• Dynamic class loading
• Performance benchmark

The pom.xml file instruct maven to compile the Java classes into a jar and then execute java4cpp on this jar to generate C++ proxies inside the java4cpp directory.
