jax-rs returning to html page that called it

Hi Guys,
Need a helping hand.
I'm trying to strech my limits I have no problem doing the following in javascript, but I'm trying to push my self into learning some REST.
What i'm trying to do is create a html interface that sends two numbers into a rest web services and then performs a calculation on those values.
There is no problem with the service itself and currently the result is displayed on a new web page.
What I'm trying to do is to get the result from the web service back onto the same page as the one the called it.
here is the code

Here is the html

and here is the rest or jax-rs

import javax.ws.rs.*;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.FormParam;
import javax.ws.rs.QueryParam;

@Path("multiplier")
public class MathsSum 
{
    @GET
    @Path("getMathsMultiplier")
    @Consumes("text/html")
    @Produces("text/html")
    public @QueryParam("result") String getMathsMultiplier(@QueryParam("value1") String val1, @QueryParam("value2") String val2)
    {
        int temp1;
        int temp2;
        int total;
        String strTotal;
        
        if ((isNumber(val1)) && (isNumber(val2)))
        {
            temp1 = getInt(val1);
            temp2 = getInt(val2);
            total = temp1 * temp2;
            strTotal = conString(total);
            
        }
        else
        {
            strTotal = null;
        }
           
        return strTotal;
    }
    
    public boolean isNumber(String string)
    {
        try 
        {
            int tempNum = Integer.parseInt(string);
            return true;
        }
        catch(Exception e)
        {
            return false;
        }
    }
    
    public int getInt(String string)
    {
        return Integer.parseInt(string);
    }
    
    public String conString(int intVal)
    {
        return Integer.toString(intVal);
    }
}

it's configured through netbeans and glasssfish server
I would appreciate any help

Ajax is the answer.
