Calling Java Class in ColdFusion

here is my java code:
public class JavSq {
     public static int squar()
     {
          int result;
          result = 5 * 5;
          return result;    
     }
}
here is my coldfusion code:

<CFOBJECT ACTION="Create"
     TYPE="Java"
     CLASS="JavaSq"
     NAME="myJava">

     <CFSET myResult = myJava.squar()>
     <CFOUTPUT>Result is #myResult#
     </CFOUTPUT>

when i run the cfm file i encounter this error:
"
The JVM library could not be found. Please check if the file specified in the ColdFusion Administrator actually exists.

The error occurred while processing an element with a general identifier of (CFOBJECT), occupying document position (8:1) to (11:15)."

I've installed jdk1.2.1 at the server and also specified the jvm lib path. i copied my class file to the class path specified at the CFadmin.
Please advice me on the problem. Thank you
