    }
    else if("page" == b) {
     return "b.jsf";
    }
}

and i to use pretty url example in old way jsf page will display url

开发者_开发问答

http://localhost/index.jsf?page=a or http://localhost/index.jsf?page=b

but i want use pretty url instead of old way, example:

http://localhost/index/a

how can i do it (it mean using pretty faces and how i can use if-else for what?) i can explain above question here instead of above i use if("page"=a) if i use old way paste parameter url http://loalhost/index.jsf?page=a but if i use pretter url or pretty faces what would i do for if-else statement? if(?? = a)

2 question please help me thankyou

  ==========================================================

Now i set up pretty faces and work well but i dont know how can i get parameter from Prettyfaces, in Pretty-config.xml i was config page follow:

Main page ( content change dynamic in there)

<url-mapping id="mainpage">
 <pattern value="/home" />
 <view-id>/faces/main.xhtml</view-id> 
</url-mapping>

Page1

<url-mapping id="mainpage">
 <pattern value="/home/#{page:content1}" />
 <view-id>/faces/content1.xhtml</view-id> 
</url-mapping>

page 2

<url-mapping id="mainpage">
 <pattern value="/home/#{page:content2}" />
 <view-id>/faces/content2.xhtml</view-id> 
</url-mapping>

in page one i use ui:include for dynamic subview

<ui:include src=#{bean.includePage}/>

my bean have one method for get include page

  public String getIncludePage(){
       if(page == null){
        return "content.xhtml";
       }
       else if (page.equals(content1)){
        return "content1.xhtml";
      }
      else if (page.equals(content2)){
        return "content2.xhtml;
      } 
}

But i can't change dynamic page view content in one page

If I understood your question correctly your problem has nothing to do with PrettyFaces.

Is it correct that you want to end up with different pages which share the same header and footer? In this case you should really learn about templating with Facelets because this is exactly an usecase for it.

Here a short example on how Facelets work:

template.xhtml:

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:ui="http://java.sun.com/jsf/facelets">
<head>
  <title>
    <ui:insert name="title" />
  </title>
  <link rel="stylesheet" type="text/css" href="./css/main.css"/>
</head>

<body>

<div id="center">
  <ui:insert name="title" />
  <hr />
  <ui:insert name="content" />
</div>

</body>

</html>

some-page.xhtml:

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:ui="http://java.sun.com/jsf/facelets"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:f="http://java.sun.com/jsf/core">

<ui:composition template="/template.xhtml">
  <ui:define name="title">My Page Title</ui:define>
  <ui:define name="content">

    <p>
      This is the main content area
    </p>

  </ui:define>
</ui:composition>
</html>

I recommend to read Facelets fits JSF like a glove. It's an really great article on Facelets.
