JSP 页面中：

<br/>
(1) : <%=request.getContextPath()%>
<br/>
(2) : <%=request.getServletContext().getRealPath("/")%>
<br/>
(3) : <%=request.getServletContext().getRealPath("")%>

System.out.println("servlet(1) : "+this.getServletContext().getContextPath());
System.out.println("servlet(2) : "+this.getServletContext().getRealPath("/"));
System.out.println("servlet(3) : "+this.getServletContext().getRealPath(""));

输出为：

servlet(1) : /Html5_Video_Simple_01
servlet(2) : ...workspace__MyEclipse2013.metadata.me_tcat7webappsHtml5_Video_Simple_01
servlet(3) : ...workspace__MyEclipse2013.metadata.me_tcat7webappsHtml5_Video_Simple_01
