help!!! passing info to text file

Hello, I am extremely new to java and I just need some basic advice. My company develops statistical models that read from text files. I want

a)people to be able to go to my site enter values into a form and pass those values to a text file.

b)execute the model (nothing special just like calling a regular .exe)

c)display the results from a text file (the model writes to a text file) into the browser

I understand that this is very basic stuff but I need somewhere to start. Could I have some advice? If you could point me to any articles, code, tutorials on this I would really appreciate it.

Servlets will handle those tasks quite easily. Youll have to import java.io.*;

For writing to a file, you could use something like

FileWriter writer = new FileWriter("user/default/file.txt");
BufferedWriter doWrite = new BufferedWriter(writer);
doWrite.write("Testing");
doWrite.flush();
doWrite.close();
writer.close();

For Reading use something like this

FileReader reader = new FileReader("user/default/file.txt");
BufferedReader doRead BufferedReader(preader);
String whatever;
//Then for each line to read in use
whatever=doRead.readLine();
doRead.close();
reader.close();
//Once you invoke the readLine() method the pointer automatically hops to the next line, so whatever=doRead.readLine(); will read in the next line without you having to jump to it.

Do a search on google for "doGet" and "getParameter()" for handling forms.
I hope this helped.
