To wrap up what was already done, here is the source code for the template, specification and class for the Home page: Home.html: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>Guess the Word</title> </head> <body> <h2>Guess the Word</h2> <form action="" jwcid="secretWordForm"> Enter the secret word: <input type="text" jwcid="secretWord"/> <input type="submit" value="Submit"> </form> </body> </html> Home.page: <?xml version="1.0"?> <!DOCTYPE page-specification PUBLIC "-//Apache Software Foundation//Tapestry Specification 4.0//EN" "http://tapestry.apache.org/dtd/Tapestry_4_0.dtd"> <page-specification class="com.devshed.tapestry.guesstheword.Home"> <component id="secretWord" type="TextField"> <binding name="value" value="theWord"/> <binding name="hidden" value="true"/> </component>
<component id="secretWordForm" type="Form"> <binding name="listener" value="listener:onWordSubmit"/> </component>
</page-specification> Home.java: package com.devshed.tapestry.guesstheword; import org.apache.tapestry.html.BasePage; public abstract class Home extends BasePage {
public Home() { }
public abstract String getTheWord();
public String onWordSubmit() { return "Secret"; }
