in jsp, get realPath of deployed project

in servlet, as we can access the real path of deployed project

ServletContext context = getServletConfig().getServletConte开发者_如何学Cxt();
string contextStr = context.getRealPath(".....");

How can i access the deployed project path in JSP page, any idea please ?

<%=request.getRealPath("write_your_file_name")%>

It should work just the same, for example by accessing ${pageContext.servletContext.getRealPath("...")} to get the same results. JSP are nothing more than servlets after they got compiled.

note, as of version 2.1 you should use

request.getServletContext().getRealPath("your_file_name")
