Java HotSpot Virtual Machine

Hi everyone, i am trying to learn jni,i got these codes on the web and am i trying them out. now i have a problem.

first here are the codes:
jniexample.java

import java.io.*;
import java.util.*;

class jniexample {                                                              
   static {
        try {
            System.loadLibrary( "jniexample" );
	      } 
	     catch( UnsatisfiedLinkError e ) {
	        System.out.println( "Could not load native code." ); 
	      System.exit(1);
	    }
   }

   public static void main( String [] args ) throws IOException {               
        
      String strUser;
      String strPass;
      BufferedReader console = new BufferedReader( new InputStreamReader( System.in ) ); 
         
         strUser = console.readLine();                                                            
         strPass = console.readLine(); 
 
	 validUser( strUser, strPass );                                  
   }                                                                            
                            
   public static native boolean validUser( String strUser, String strPass );    
}  

jniexample.cpp

JNIEXPORT jboolean JNICALL Java_jniexample_validUser
  ( JNIEnv *env, jobject obj, jstring user, jstring pass )
{
  struct spwd   *pw;
  char          salt[2];
  char          *cpass;
  jboolean      retVal= JNI_FALSE;
  
  const char *pUser = env->GetStringUTFChars( user, 0 );
  const char *pPass = env->GetStringUTFChars(pass, 0 );
  
  printf("Hello %s, you are wellcome with password %s\n",pUser,pPass);
 
                                                   
   env->ReleaseStringUTFChars(pass, pUser );
  env->ReleaseStringUTFChars(pass, pPass );                           
retVal = JNI_TRUE; 
  return retVal;                                                               
}

my steps:

javac jniexample.java
javah -jni jniexample
g++ -shared -o libjniexample.so jniexample.cpp -lstdc++ -I/usr/lib/jvm/java-6-sun/include -I/usr/lib/jvm/java-6-sun/include/linux

now when i run the program i get the error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: jniexample.validUser(Ljava/lang/String;Ljava/lang/String;)Z
at jniexample.validUser(Native Method)
at jniexample.main(jniexample.java:24)


also i have done:

export LD_LIBRARY_PATH=(CURRENT DIRECTORY WHERE THE libjniexample.so IS LOCATED)

please give me suggestions ,,,thanks in advance
