Before Implementing the JSF Dashboard

So, I’m going to create more of a ‘dashboard’ application, at least from the development standpoint. So, while my RPS application has three possible outcomes, win lose or tie, I only want to use one JSP page, the index.jsp.

Here’s the RockPaper

 

package com.mcnz.jsf.bean;

import javax.faces.context.FacesContext;

public class RPSBean {
    private String clientGesture = null;
    private String computerGesture = null;
    public String getClientGesture() {return clientGesture;}
    public void setClientGesture(String clientGesture) {this.clientGesture = clientGesture;}

    public String getComputerGesture() {return computerGesture;}
    public void setComputerGesture(String computerGesture) {this.computerGesture = computerGesture;}

    public String doRockPaperScissorsGame() {
        String result = "failure";
        java.util.Map requestParameterMap = FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap();
        this.computerGesture = "rock";
        if (clientGesture.equalsIgnoreCase("scissors")){
            result = "youlose";
        }
        if (clientGesture.equalsIgnoreCase("paper")){
            result = "youwin";
        }
        if (clientGesture.equalsIgnoreCase("rock")){
            result = "tie";
        }
        System.out.println(clientGesture);
        return result;
    }
}

And here’s the faces-config.xml file:

And here’s the landing page, the index.jsp file:

</head>

    <body>

    Please chose between Rock Paper and Scissors:
    <h:form id="rpsgame"  >
        <h:inputText id="gesture" value="#{rpsbean.clientGesture}"></h:inputText>
        <h:commandButton id="submit" type="submit" value="Play!" action="#{rpsbean.doRockPaperScissorsGame}" ></h:commandButton>
    </h:form>
