public class TomcatDir extends HttpServlet {

    public void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        System.out.println(System.getProperty("user.dir"));　　　　//D:\apache-tomcat-6.0.41\bin
        System.out.println(System.getProperty("catalina.home"));　　//D:\apache-tomcat-6.0.41 不建议使用,获取的是环境变量中tomcat的位置
        HttpSession session = request.getSession();      
        ServletContext  application  = session.getServletContext();    
        String serverRealPath = application.getRealPath("/") ;
        System.out.println(serverRealPath);　　　　　　　　　　　　　　//D:\apache-tomcat-6.0.41\webapps\test2\
        File f = new File(getClass().getResource("/").getPath()); 
        f = new File(f.getPath().replace("%20"," ") + "/databasePool.conf"); 
        System.out.println(f.getAbsolutePath());　　　　　　　　　　　　//D:\apache-tomcat-6.0.41\webapps\test2\WEB-INF\classes\databasePool.conf
        String path = request.getContextPath();
        String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
        System.out.println(basePath);　　　　　　　　　　　　　　　　　　//http://localhost:8080/test2/
        System.out.println(request.getContextPath());　　　　　　　　　// /test2
    }

    public void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        doGet(request, response);
    }

}

 输出结果:

D:\apache-tomcat-6.0.41\bin
D:\apache-tomcat-6.0.41 //不建议使用,获取到的是环境变量中tomcat的位置
D:\apache-tomcat-6.0.41\webapps\test2\
D:\apache-tomcat-6.0.41\webapps\test2\WEB-INF\classes\databasePool.conf
http://localhost:8080/test2/
