vxUtils::jvm

This library contains an experimental implementation of a Java Virtual Machine for vxWorks operating system. This is actually a port of jArt java machine I've developed in another project.

The latest version 1.0.0 can be downloaded via this link.

Supported features

• Java bytecode interpretation (no JIT for the moment);
• Loading classes from JAR files (using zlib);
• Native system threads;
• Internal heap implementation (system heap is almost not used);
• Mark&sweep garbage collector;
• Minimalistic classpath implementation;
• Private interface to native methods;
• Can be compiled for vxWorks or Linux.

Compiling

Be sure you have VXWORKS flag defined (e.g. CFLAGS+=-DVXWORKS) when building for VxWorks target. When building for Linux, VXWORKS flag must not be defined.

Example of usage

The main entry point to JVM is contained in file jvm.c, function jvm_start(). This function starts the Java machine and executes a static method

public static void sys.entry.Entry.entry()

of sys.entry.Entry class.

Please follow this link or take a look at jvm.c file contained in jvm package.
