in this subdirectory are visible to application classes, but not to Web users, WEB-INF is often used for vendor-specific purposes JRun, for example, creates a subdirectory named jsp that contains the Java source code and compiled classes for servlets generated from JSP pages JRun also creates a subdirectory named sessions, which holds serialized versions of any HTTP sessions that are active when the servlet engine is brought down In general, WEB-INF is suitable for any data you want to use in a Web application while keeping it hidden from direct access by users

Web servers have a document root directory that primarily contains HTML files In Apache, for example, this is <apache root>/htdocs Microsoft Internet Information Server (IIS) uses inetpub/wwwroot When a URL is clicked in a Web browser, the browser breaks it down into its server and path components and generates an HTTP request to the server for the specified resource The Web server, when it receives the request, extracts the path from the request header and translates it into a path relative to the document root directory For example, if the URL is

A Web application also has a document root directory, as you ve seen, but this root can be anywhere in the file system The servlet engine, when it recognizes an HTTP request is for a servlet or JSP page, extracts the Web application name from the URL and maps the rest to a resource within that application For example, if the URL is
http://wwwlyricnotecom/products/contest/rulesjsp
18:
Deploying Web Applications
then the servlet engine creates a request for /contest/rulesjsp and passes it to the products Web application1 Servlets are handled similarly A URL like
http://wwwlyricnotecom/products/servlet/Counter
gets passed to the products Web application as a request for the Counter servlet2 URLs used in a servlet or JSP page within an application to refer to another resource within the application don t use the application name For example, if the rulesjsp page needs to include the output of the Counter servlet dynamically, it uses this statement
<jsp:include page= /servlet/Counter flush= true />
not this statement
<jsp:include page= /products/servlet/Counter flush= true />
The same applies to URLs used by <jsp:include>, the <%@ include %> directive, the <%@ taglib %> directive, and methods that create RequestDispatcher objects The rule for interpreting these relative URL s is this: I If the URL begins with /, it s interpreted as being relative to the application root directory I If it doesn t begin with /, it s interpreted as being relative to the current JSP page This brings up a subtle difficulty, however URLs in a JSP page used as hyperlinks, form actions, style sheet links, or image sources are interpreted by the browser, not the server If the LyricNote home page is a JSP page with a link to /products/contest/ rulesjsp, the link cannot be hardcoded with the products application name Why not Because the application name isn t necessarily going to be products This depends entirely on where the system administrator chose to install the Web application It could have been mounted as product_test or staging_area or anything else Only when the application is actually running can a JSP page know the name, which can be obtained from the requestgetContextPath() method
JSP IN ACTION
Strictly speaking, the portion of the URL that constitutes the Web application name can be a multilevel string like /products/test/Wednesday, but it s more common for a single token to be used The <servlet-mapping> element of the deployment descriptor can be used to map any URL substring to a particular servlet Shown here are the default mappings
