favorite I folks:

I know that CGI is jurassic and before all of you call me lunatic, I must say that this question is only for EDUCATIONAL PURPOSES (in real cases I use JSP).

I'm trying to code a "Hello World" CGI in Java, and I'm unsucessful.

So I try the same job in C#. Both programs (C# and Java) are totally equal (line by line). The C# works and the Java don't.

Here's the code in C#:

namespace CGI_CSharp
    class Program
        static void Main(string[] args)
            Console.WriteLine("Content-Type: text/html\n"); // the extra "\n" is needed
            Console.WriteLine("<title>CGI - C#</title>");

            Console.WriteLine("<h1>Hello World !</h1>");


In the browser URL I wrote: http://localhost/CGI_CSharp.exe and BINGO! The C# code WORKS !

Now the same code in Java:

public class CGI_Java
    public static void main(String[] args)
        System.out.println ("Content-Type: text/html\n");
        System.out.println ("<html>");
        System.out.println ("<head>");
        System.out.println ("<title>CGI - Java</title>");
        System.out.println ("</head>");
        System.out.println ("<body>");

        System.out.println ("<h1>Hello World !</h1>");

        System.out.println ("</body>");
        System.out.println ("</html>");

Now I've tried the URL:


(as you know, the %20 is the space => (http://localhost/java.exe CGI_Java)

I get:

HTTP 404.0 - Not Found

So, I try again, now with a batch file (CGI_Java.bat) with a single line of text:

java.exe CGI_Java (content of the CGI_Java.bat)

And now, I try the URL:


Now the browser shows:

C:\inetpub\wwwroot>java.exe CGI_Java

This is the prompt followed by the command I wrote in the batch file.

Can someone help me?

Thanks in advance.

Please do not post the same question in multiple forums; you already posted this here[^].

Sorry for that. I thought the first post was not published, only realized this after submitting the second post. This is my first post in this forum.
