JNI Program RunTime Exceptions

[Rajesh Kumar]

Hai friends
I am trying to call the Functionality from C program to Java Program using JNI
The C program is like
#include <jni.h>
#include "HelloWorld.h"
#include <stdio.h>
JNIEXPORT void JNICALL
Java_HelloWorld_displayHelloWorld(JNIEnv *env, jobject obj)
{
printf("Hello world!\n");
return;
}

Java Program is
class HelloWorld
{
public native void displayHelloWorld();

static
{
System.loadLibrary("hello");
}
public static void main(String[] args)
{
new HelloWorld().displayHelloWorld();
}
}
I compiled java program using this
javac HelloWorld.java
and i made it as .h file using
javah -jni HelloWorld
Everything is fine but when i am trying to run the java program like this
java HelloWorld
It is saying exception
Exception is
java.lang.UnsatisfiedLinkError: no hello in shared library path
at java.lang.Runtime.loadLibrary(Runtime.java)

Do you have the line you're using to compile the code? What directory are you putting the .dll/.so file in?

The problem is that what u expressed.
Now I kept .dll file in the directory where class files and .h files stored.
now it is working fine.
