Errors when creating java webservice using Axis 1.4

Hello,

Im trying to create a simple web service using Axis 1.4 and Tomcat in Java. I have setup Axis 1.4, by adding the Axis jars to my CLASSPATH, also i have set AXIS_HOME. In my project folder i have two subfolders, src and classes. In src\org\test\wssample, i have SimpleCalculator.java,defined as

package org.test.wssample;

public class SimpleCalculator {

    public int add(int a, int b) {
        return a + b;
    }
    public int subtract(int a, int b) {
        return a - b;
    }
    public int multiply(int a, int b) {
        return a * b;
    }
}

In src\org\test\wssample\ws, i have created the web service interface in Calculator.java , defined as :

package org.test.wssample.ws;

public interface Calculator {
    int add (int x, int y);
    int subtract(int x, int y);
}

After,compilation i have SimpleCalculator.class in classes\org\test\wssample and Calculator.class in classes\org\test\wssample\ws.

Now, i run the following command in my classes folder to generate the WSDL file

java org.apache.axis.wsdl.Java2WSDL -o ..\calculator.wsdl -n urn:org.test.calculator -I http://localhost:9090/axis/services/calculator org.test.wssample.ws.Calculator

But,i get the errors shown below.
