Hi,

so I try calling a method (C) in my jni library for testing.

The java method is as followed:
public void call()
{
System.out.println("testing 3");
Hello h = new Hello();
h.sayHello();
System.out.println("testing 3 passed");
}

//File: Hello.c
#include <jni.h>
#include "Hello.h"
#include <stdio.h>
JNIEXPORT void JNICALL Java_test_Hello_sayHello
(JNIEnv *env, jobject obj)
{
printf("Hello world!\n");
return;
}

However, it seems that h.sayHello method is called only after I closed the plug-in.
print-out:
testing 3
testing 3.5 passed
testing 4 passed
passed
Hello world! ....

How can I call it without closing the plug-in?

Thanks,
MC

Hi Mark,

This newsgroup is for TPTP profiling questions/discussion only. I suggest
you try report to the JDT/CDT newsgroup.
