[SOLVED] Wildcard mapping on Struts2

Wildcard mapping on Struts2

I followed an online tutorial on how to use Wildcard technique in Struts2 but it does not work as shown. On execution of the command, it only calls the execute() method and never calls any other methods. I'm not sure what the issue is, but any help would be amazing.

Below are my action file and the struts file linking the action to the JSP calls on the JSP page.

CalculatorAction.java

package com.simplecode.action;

import com.opensymphony.xwork2.ActionSupport;

public class CalculatorAction extends ActionSupport
{
    private float number1;
    private float number2;
    private float result;
    private String methodName;




    public String add()
    {
        System.out.print("afsnjfbkjsdfhdskfhsdkjfhksdjfhkdsjfhksdjfhsdkjfhksjfhkjdsfhdsk");
        result=number1+number2;
        setMethodName("add Method");
        return SUCCESS;
    }

    public String subtract()
    {
        result = number1 - number2;
        setMethodName("subtract Method");
        return SUCCESS;
    }

    public String multiply()
    {
        result = number1 * number2;
        setMethodName("multiply Method");
        return SUCCESS;
    }

    public String divide()
    {
        if(number2!=0)
            result = number1/number2;
        else if(number1!=0)
            result = number2/number1;
        else
            result=0;

        setMethodName("divide Method");
        return SUCCESS;
    }

    public float getNumber1() {
        return number1;
    }

    public void setNumber1(float number1) {
        this.number1 = number1;
    }

    public float getNumber2() {
        return number2;
    }

    public void setNumber2(float number2) {
        this.number2 = number2;
    }

    public float getResult() {
        return result;
    }

    public void setResult(float result) {
        this.result = result;
    }

    public String getMethodName() {
        return methodName;
    }

    public void setMethodName(String methodName) {
        this.methodName = methodName;
    }
}

Solution

You need to also set the action prefix enabled constant, e.g.,

<constant name="struts.mapper.action.prefix.enabled" value="true"/>

This is kind of a hack; it can be a little risky to allow access to arbitrary action methods.
