1. System properties added by default on the application server

NetBeans Create Java Web Project (ctxtest) (index.jsp)

<%@page Import="java.util.Properties"%><%@page ContentType="text/html"pageencoding="UTF-8"%><!DOCTYPE HTML><HTML>    <Head>        <Metahttp-equiv= "Content-type"content= "text/html; charset=utf-8">        <title>JSP Page</title>    </Head>    <Body>        <Table>            <% Properties props  =  system.getproperties ();  for (StringName:props.stringPropertyNames ()) {Out.println ("<tr><td>" +name+ ": </td><td>" +props.getproperty (name)+ "</td></tr>" ); }            %>        </Table>    </Body></HTML>

2. File system Naming Service (requires Fscontext.jar and Providerutil.jar)

NetBeans Create Java Project (Fscontext): (Nameservicetest.java)

 PackageLee;Importjava.util.Hashtable;ImportJavax.naming.Context;ImportJavax.naming.InitialContext;Importjavax.naming.NamingException; Public classNameservicetest { Public Static voidMain (string[] args)throwsnamingexception{FinalString fileName = "00. Directory. docx"; FinalString dirName = "Codes"; Hashtable Env=NewHashtable (); Env.put (Context.initial_context_factory,"Com.sun.jndi.fscontext.RefFSContextFactory"); Env.put (Context.provider_url,"File:/d:/javaee traditional/fscontexttest"); Context CTX=NewInitialContext (env); Object file = ctx.lookup (fileName); System.out.println (FileName+ "name is bound to:" +file); System.out.println (The type of file is: "+File.getclass ()); Object dir = ctx.lookup (dirName); System.out.println (DirName+ "name is bound to:" +dir); System.out.println (The type of Dir is: "+Dir.getclass ());    Ctx.close (); }  }

Nameservicetest2.java
