A web application can be deployed online via a server. You will need to pay in order to purchase a server.
Deploy = build packet application that use by user to install your program Deploy = Finishing & Packaging In Java : - desktop : usually we deploy application to *.jar files - web app : usually we deploy it to *.war files feel free to visit http://www.javaclopedia.com
Any Web Application has a hierarchical structure (of folders) that is used for packaging the web applications. The application needs a reference point within the hierarchical structure. Here, let's call it TOMCAT_HOME. This represents the root of your server (Tomcat) installation, not your Web application root. When we talk of a Web application's context, we are referring to that Web application's root directory or path within a particular server. A special directory exists within the application hierarchy named WEB-INF. This directory contains all things related to the application that aren't in the document root of the application. It is this WEB-INF directory that is the Web application's root directory, also referred to as the context. The most important file here is web.xml, the name of the WebApp deployment descriptor. Let us take a look at the various contents (files & folders) that will be present inside this WEB-INF directory: 1. /WEB-INF/web.xml - This is the Deployment Descriptor file 2. /WEB-INF/classes/ - This is the directory where all your java class files will be placed 3. /WEB-INF/lib/ - This is the folder where all your JAR files go. The classes folder is where you will place the .class file of your Servlet to deploy it on a server

The deployment descriptor is an xml file that contains the basic and most important information that is required to deploy a web application (Servlet) Without this, the web server would not know, which requests to entertain/consider as requests to access this servlet.
what a vulnerability of web based application
In web server you can deploy static contect and web server used to redirect http and https requests to application server and a proxy server can integrate multiple servers to handle webserver requests on behalf of webserver to application server.
You Run a Servlet by deploying it on the server, which in this case is tomcat. We need to deploy the servlet in the Web Applications context. When we talk of a Web application's context, we are referring to that Web application's root directory or path within a particular server. A special directory exists within the application hierarchy named WEB-INF. This directory contains all things related to the application that aren't in the document root of the application. It is this WEB-INF directory that is the Web application's root directory, also referred to as the context. The most important file here is web.xml, the name of the WebApp deployment descriptor. Let us take a look at the various contents (files & folders) that will be present inside this WEB-INF directory: 1. /WEB-INF/web.xml - This is the Deployment Descriptor file 2. /WEB-INF/classes/ - This is the directory where all your java class files will be placed 3. /WEB-INF/lib/ - This is the folder where all your JAR files go. my tomcat is installed in c:\dev\java\Jakarta-tomcat-4.0.1. This is my TOMCAT_HOME. Remember that, this path that is referred by TOMCAT_HOME might vary from PC to PC depending on the installation preferences of the user. To Deploy the Servlet, you need to place the .class file corresponding to your servlet in the /WEB-INF/classes/ folder
progressive web
The function of the web-based application is to implement webmail, online retail sales, discussion boards, wikis, and the online auctions. The web application can be described as an application that is accessed via a web.
Just about anything. But most people deploy them as web servers.
