POUnderstanding the "Welcome to Play 2.0" page creation

copied!<p>I have just started to try to work with the play framework and tried to understand this default application you get when creating a new project.</p> <p>So as far as I understand, when loading the localhost page, a http get request comes in and is directed to the <code>Application.index()</code> method because of the specification in the routes file? In the <code>index()</code> method a lot of HTML code is generated and returned in a Result object and passed to the <code>index.scala.html</code> file which hands it over to the <code>main.scala.html</code> where it is surrounded with more html.</p> <p>Now, a few things are unclear to me:</p> <ul> <li><p>in <code>Application.java</code> there is this line <code>return ok(index.render("Hello World!"));</code> index belongs to <code>views.html.*</code>; but where is this package? I can't find it in the API :(</p></li> <li><p>why can't I rename the <code>index.scala.html</code> file? Is the name a convention?</p></li> <li><p>in the <code>index.scala.html</code> file itself: what does <code>@play20.welcome(message, style = "Java")</code> do? is this getting the "Welcome to Play 2.0" site? and again - I can't find the documentation/API entry for the play20 thing :(</p></li> </ul> <p>I hope, somebody can help me to get an overview, as I am really confused at the moment..^^ I have done a lot of java, but no web programming at all, therefore this mix of all the different technologies and languages is quite strange at the moment!</p>
