Ch Java


Ch Java Toolkit is a package for running C/Ch/C++ code in Java and running Java in C/Ch/C++. Either a Java program can access the C/Ch/C++ script or a C/Ch/C++ program can invoke a JVM and execute a Java program. Core JNI functions is supported in Ch Java ToolKit.

Java is one of the most popular languages for any web based application. Its portability feature puts ahead of other language. But when it comes to access of hardware and native functions there lies the problem of portability. Even though the Java code is portable the corresponding native function has to compiled in every other OS.

With Ch Java one can develop applications involving Java and native function but still portable. This ability of ChJava being portable, it makes ChJava the right candidate for platform independent JNI application, rapid prototyping and embedded scripting. One of the major attraction of ChJava usage could be with respect to its usage when its applet communicating with the server using JSP and is hosted using a Tomcat webserver. The Ch script that runs in the back end can be modified at any point of time with out restarting the server which is not possible now with a native function alone.

The integration of Ch and Java has been performed using two different technologies namely Ch SDK and Embedded Ch. A Java program can be called from a C program without compiling which was not possible before. And a Ch Script can be called from a Java program through JNI and this Ch Script can be modified during runtime without affecting the performance or stopping the execution.
