I am new to JSP. When I used to work with ASPX I created a project with a master page, the <body> of the master page was like this:

<body>
    <asp:ContentPlaceHolder ID="MainContent" runat="server">
    </asp:ContentPlaceHolder>        
</body>

and every ASPX file except the master had in the beginning MasterPageFile="~/Site.master" for example

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

and wrote only in MainContent like this:

<asp:Content ID="BodyContent"  ContentPlaceHolderID="MainContent">
    code ...
</asp:Content>

Now I want to create same idea in JSP. How can I define the master and how I can define that the other JSP will be under the control of the master`?

You can have a decorator – the master – for the pages that you want.

I use an xml to define which page has which decorator, something like:

<decorator name="name" page="decorator.jsp">
    <pattern>/folderName/*</pattern>
    <pattern>/folerName2/*</pattern>
</decorator>
