In apache server,I want to use java to output something to the client,here's the java code public class Compile { public static void main(String[] args) { System.out.println("Hello world"); } } it just simply output a hello world,then I compiled it an copy Compile.class to server's root.there is also a cmd file there(the OS is windows),the compile.cmd @echo off echo Content-Type: application/x-javascript echo. echo start java Compile it has been good so far,if I execute it in command line the "hello world" will be shown. in apache's config file ExecCGI has been on and AddHandler cgi-script .cmd also been added. however,by visit [http://localhost/compile.cmd,only "start" displyed,the java's output "Hello world" disappeard.I can't find why the same problem can be fond here http://www.gossamer-threads.com/lists/apache/users/189828
