i want to run java from go,but it didnot work

i want to run java from go. first, i try to run java from c, it work. bug it can't run from go.

(windows 10 64)

1

the java code

HelloWorld.java

public class HelloWorld{
    public static void sayhello(){
        System.out.println("Hello World from java !");
    }
}

2

> javac HelloWorld.java 

generate a file 'HelloWorld'

3

> javap -p -s HelloWorld

Compiled from "HelloWorld.java"
public class HelloWorld {
  public HelloWorld();
    descriptor: ()V

  public static void sayhello();
    descriptor: ()V
}

hello.c

#include <jni.h>
#include <string.h>
int main() 
{ 
    JavaVMOption options[1]; 
    JNIEnv *env; 
    JavaVM *jvm; 
    JavaVMInitArgs vm_args; 
    long status; 
    jclass cls; 
    jmethodID mid; 
    jint square; 
    jboolean not; 

    options[0].optionString = "-Djava.class.path=."; //setting classpath
    memset(&vm_args, 0, sizeof(vm_args)); 
    vm_args.version = JNI_VERSION_1_2; 
    vm_args.nOptions = 1; 
    vm_args.options = options; 
    status = JNI_CreateJavaVM(&jvm, (void**)&env, &vm_args); 

    if (status != JNI_ERR) 
    { 
        //cls = (*env)->FindClass(env, "java/lang/Object"); 
        cls=(*env)->FindClass(env,"HelloWorld");

        printf("find the class\n");
        if(cls !=0) 
        {
            //mid = (*env)->GetStaticMethodID(env, cls, "main", "(I)I"); 
            mid=(*env)->GetStaticMethodID(env,cls,"sayhello","()V");
            printf("find the method\n");
            if(mid !=0) 
            {
                printf("exec method\n");
                (*env)->CallStaticVoidMethod(env, cls, mid, NULL); //执行方法
            } 
        } 
        else{
            printf("not found\n");
        }

        return 0; 
    } 
    else

}

gcc -I"C:\Program Files"\Java\jdk1.8.0_251\include -I"C:\Program Files"\Java\jdk1.8.0_251\include\win32 hellow_world.c -L "C:\Program Files"\Java\jdk1.8.0_251\jre\bin\server -ljvm

generate a file 'a.exe'

6

run a.exe

> a.exe

find the class
find the method
exec method
Hello World from java !

why it didn't work in golang?

hello.go

how can i run it in golang? You might get inspiration from here： https://github.com/golang/mobile/blob/master/asset/asset_android.go
