java.lang.UnsatisfiedLinkError running JNI at RedHat: Java, JNI, Linux

java.lang.UnsatisfiedLinkError running JNI at RedHat

I write a simple java hello world program with JNI. The java code and c code can be found in the code section. The program can be run at Windows environment successfully. However, I fail to run it at Red Hat 3.4.6-8. I use the following command to compile the c library.

gcc -o testnativelib.so -shared -fPIC -I$JAVA_HOME/include -I$JAVA_HOME/include/linux JNITester.c

When I run the program, the follow error is resulted.
>java JNITester abc
java.library.path is: /home/abc/temp/example
Exception in thread "main" java.lang.UnsatisfiedLinkError: no testnativelib in java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1682)
at java.lang.Runtime.loadLibrary0(Runtime.java:822)
at java.lang.System.loadLibrary(System.java:992)
at com.cargosmart.mcci.test.JNITester.<clinit>(JNITester.java:9)

the testnativelib.so is at /home/abc/temp/example. And I have run the command LD_LIBRARY_PATH=`pwd`
export LD_LIBRARY_PATH

Do you have any idea on the problem?

public class JNITester 
{
	static 
	{
		String libPath = System.getProperty("java.library.path");
		System.out.println("java.library.path is: " + libPath);
		System.loadLibrary("testnativelib");
	}
	
	native String helloWorld(String name);
	
	public static void main(String[] args) 
	{
		JNITester jniTester = new JNITester();
		System.out.println(jniTester.helloWorld(args[0]));
	}
}
 
#include <jni.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
 
JNIEXPORT jstring JNICALL Java_JNITester_helloWorld(JNIEnv *env, jobject jobj, jstring name)
{
	jboolean iscopy;
	jstring jresult;
	char *greet_str;
	const char *input_name = (*env)->GetStringUTFChars(env, name, &iscopy);
	greet_str = (char*) malloc(sizeof(char) * 50);
	strcpy(greet_str, "Hello, ");
	strcat(greet_str, input_name);
	jresult = (*env)->NewStringUTF(env, greet_str);  
	(*env)->ReleaseStringUTFChars(env, name, input_name);
	return (jresult);
}
