Since you are coding jsp, I am assuming you have java programming knowledge. To read a file, you need java io package to be imported. So, here goes the import page directive at top of your jsp.

CODE
<%@page import="java.io.*"%>


Now, you have to create input stream using the file. Assuming the file is in the class path, you can get the stream by

CODE

java.net.URL url =config.getServletContext().getResource("yourfile.txt");
BufferedReader buffreader =new BufferedReader(new InputStreamReader(url.openStream()));


Rest of the things are same as reading from a BufferedReader in java. Make sure that the java code in jsp is inside <% and %> tags.

  5. Running .java Or .class Files From Runtime
    (1)
    from an API and outputs the result to the API (like someAPI.submitResult(myResult), which checks the
    results against the sample values. The idea is that the student is able to click a browse button and
    locate their .java or .class file, which the GUI then launches. So my question is if I can launch
    this class as part of the GUI process so that the API actually is actually part of the GUI process.
    It's a bit backwards really - like launching the API first and then adding in the component that
    uses the API during runtime. But there is an advantage of doing it this w....
