package com.dev.ws.security.ejb;
public interface Calculator extends javax.ejb.EJBObject {
   public float multiply(float a, float b) throws java.rmi.RemoteException;
}
The EJB bean simply implements the multiply method as follows: 
package com.dev.ws.security.ejb;
public class CalculatorBean implements javax.ejb.SessionBean {
...
   public float multiply(float a, float b){
		return a*b;
	}
}

After starting the server and running the client, you can use a TCP/IP monitor at port 
9080 to observe the messages that the client sends to the web service. You should observe 
a SOAP message that looks like this: 
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
   xmlns:xsd="http://www.w3.org/2001/XMLSchema"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <soap:Body>
      <multiply xmlns="http://ejb.security.ws.dev.com">
         <a>5.0</a>
         <b>7.0</b>
      </multiply>
   </soap:Body>
</soap:Envelope>
The client outputs the expected result after getting the SOAP response: 
5.0 * 7.0 = 35.0
