UnsatisfiedLinkError when using JNI?

I want to call a C program from a Java program using JNI on linux ubuntu.

I am new to this, and I tried the sample program provided at http://www.ibm.com/developerworks/java/tutorials/j-jni/section2.html . I have already created .java, .h, .c and .so files. But when I tried to run the program, I get the following error.

Exception in thread "main" java.lang.UnsatisfiedLinkError: no Sample1 in java.library.path
    at java.lang.ClassLoader.loadLibrary (ClassLoader.java:1738)
    at java.lang.Runtime.loadLibrary0 (Runtime.java:823)
    at java.lang.System.loadLibrary (System.java:1028)
    at Sample1.main (Sample1.java:13)
