How can i call a CGI script from java?

Question

The subject pretty much says it all. I want to call a perl cgi script so i can read from/write to files on a server. I don't know how to sign applets and this would be the easiest way for me, if someone could please tell me.

Answer 1

Let me get this clear. Basically what u want to do is to just call a URL, right?
U can do it by using the following code:
import java.applet.*;
import java.net.*;
import java.io.*;
public class testhttp
public static void main(String[] args)
try
URL url = new URL ("http://../testcgi.cfm");
HttpURLConnection cxn =
(HttpURLConnection)url.openConnection();
cxn.setRequestMethod("POST");
cxn.setUseCaches(false);
cxn.setDoOutput(true);
cxn.setDoInput(true);
ByteArrayOutputStream bytes = new
ByteArrayOutputStream(400);
PrintWriter writer = new PrintWriter (bytes,true);
writer.print("application=map&release=1&items=prog1");
writer.flush();
cxn.setRequestProperty("Content-
Length",String.valueOf(bytes.size()));
cxn.setRequestProperty("Content-
Type","application/x-www-form-urlencoded");
bytes.writeTo(cxn.getOutputStream());
System.out.println(bytes);
String currentLine;
BufferedReader in = new BufferedReader (new
InputStreamReader(cxn.getInputStream(),"8859_1"));
while((currentLine = in.readLine()) != null) {
System.out.println(currentLine); }
catch(Exception e) { e.printStackTrace(); }
There is also a library called HTTP client which can be found at:

It's very simple to use and the documentation is all there, but their web server seems to be down right now.
Anyway, hope my post helps.
