question about Tomcat5.5 getServletContext().getContext(String url);

[Peter Chen]

Hi,

In a JSP file, there is a sentence like this:

ServletContext sc = this.getServletContext().getContext("/File");

if(sc == null){

  Logger.warn(msg,"Can't get the context of /File.");

  return;

}

 

What's the mean of this sentence?

Now, I run this application in Tomcat5.5, and find the log: Can't get
the context of /File.

How to solve this problem? Thanks.
