While using @Management annotation in the MBean class an error called "
Cannot find value method" is fired. my code is given below. the error is fired
at place mentioned in BOLD.

import org.jboss.annotation.ejb.Service;
import org.jboss.annotation.ejb.Management;
import javax.ejb.Stateful;
@Service (objectName="trail:service=calculator")
@Management(Calculator.class)
public class CalculatorMBean implements Calculator {
double growthrate;
public void setGrowthrate (double growthrate) {
this.growthrate = growthrate;
}
public double getGrowthrate () {
return growthrate;
}
public double calculate (int start, int end, double saving) {
double tmp = Math.pow(1. + growthrate / 12., 12. * (end - start) + 1);
return saving * 12. * (tmp - 1) / growthrate;
}
// Lifecycle methods
public void create() throws Exception {
growthrate = 0.08;
System.out.println("Calculator - Creating");
}
public void destroy() {
System.out.println("Calculator - Destroying");
}
}
package trail.jmx;
import org.jboss.annotation.ejb.Management;
@Management
public interface Calculator {
public void setGrowthrate (double g);
public double getGrowthrate ();
// The management method
public double calculate (int start, int end, double saving);
// Life cycle method
public void create () throws Exception;
public void destroy () throws Exception;
