Read file from localhost?

I remember there is security restriction to prevent web application from reading file that are located in same machine but not same web app folder, is that true?

Now I have a need to read real time log files from different folders of the tomcat/apache, could that be fulfilled? If can, is that just like normal java read file or there is some special way to do that?

What I want to do is kind of like clicking a button on a jsp file, it will go to some specific log folders (same machine) and read real time log files one by one, find the special things in the log and do other things, like run a exe file which contains dos command.

I know this can be done easily without using jsp/servlet, but i want to include this one to a existing web application.

You can read/write file using your web application which file is on different location than the web-app.
