GWT - RPC - 获取servlet的绝对路径来制作目录 [英] GWT - RPC - get servlet absolute path to make dir

问题描述

我尝试使用RemoteServiceServlet读取文件，但是这个文件是

• 我想创建一个与相关路径相关的目录to

absolute_servlet_path / myPackage /

但是问题是...

代码就像

  ServletContext servletContext = this.getServletContext（）; 
 String pathContext = servletContext.getRealPath（）; 
  

...不是C：/ ...，但所以我的问题是我怎样才能使用java。所以我的问题是如何使用java。 io.File与RemoteServiceServlet？

解决方案

好的...我不得不继续挖掘...

我仍然在寻找一种servlet相对路径的方式，但绝对是一种;现在我再次尝试使用上下文，但这次我修改了我的代码在这个方向...
$ b $ pre $ ServletContext servletContext = this .getServletContext（）;
String pathContext = servletContext.getRealPath（/ WEB-INF /）;


...它对我的Tomcat有用:)

我希望能节省一天

谢谢

I tried to read a file with my "RemoteServiceServlet" but the thing is

• I want to create a dir which path is related to servlet like

absolute_servlet_path/myPackage/

But the problem is...

code like

ServletContext servletContext = this.getServletContext();
String pathContext = servletContext.getRealPath("");

... gives not "C:/..." but "/" only so the code cannot be used with java.io.File object.

So my question is how can I use java.io.File with RemoteServiceServlet ?

解决方案

OK... I had to keep digging...

Still I was looking for a way of servlet relative path but an absolute one; and now again I tried to use the context but this time I modified my code in this direction...

ServletContext servletContext = this.getServletContext();
String pathContext = servletContext.getRealPath("/WEB-INF/");

... and it worked for my Tomcat :)

I hope it saves one's day

Thanks
