Using miniJVM in project

Copy C source /minijvm/c to your project source folder, copy built jar minijvm_rt.jar to you projec resource folder

#include "jvm/jvm.h"

int main(int argc, char **argv) {
    char *bootclasspath = "../../binary/lib/minijvm_rt.jar";
    char *classpath = "../../binary/libex/minijvm_test.jar;./";
    char *main_name = "test.Foo3";

    s32 ret = 1;
    MiniJVM *jvm = jvm_create();
    if (jvm != NULL) {
        jvm->jdwp_enable = 0; //value 1 for java remote debug enable
        jvm->jdwp_suspend_on_start = 0;
        jvm->max_heap_size = 25 * 1024 * 1024; //

        ret = jvm_init(jvm, bootclasspath, classpath);
        if (ret) {
            printf("[ERROR]minijvm init error.\n");
        } else {
            ret = call_main(jvm, main_name, NULL);
        }
        jvm_destroy(jvm);
    }
    return ret;
}

Third liberies

• Janino java compiler

Project: Janino
Janino is a super-small, super-fast Java compiler.
Janino can not only compile a set of source files to a set of class files like JAVAC, but also compile a Java expression, a block, a class body, one .java file or a set of .java files in memory, load the bytecode and execute it directly in the same JVM. Janino compiler is not the full java compiler, see limitation , like :

List<String> list=new ArrayList();
list.add("abc");
String s=(String)list.get(0);//can't ignore (String) cast qualifier.

Download jars :
janino.jar
commons-compiler.jar

#compile /binary/res/BpDeepTest.java
