Poblem in Compiling a c++ file from a java program...

[Amit Kr. Mishra]

// This is the program to Compile a c++ file from a java program, & get compiler generated files in the file's parent directory.

//problem is that though it neither generate err nor throws exception, yet doesn't compile, PLEASE HELP. or suggest any other solution

import java.io.*;

class CompileCppFile{
File file;

CompileCppFile(File file){
this.file = file;
}

public void compile(){
try{
[COLOR="DarkRed"]String[] cmd = new String[4];
cmd[0] = "cmd.exe";
cmd[1] = "/C";
cmd[2] = "PATH = C:\\TC\\BIN"; //where C++ is installed.
cmd[3] = "TCC " + file.getName(); //not working. but why? [url]http://www.java-forums.org/images/smilies/confused.gif[/url]
:confused:

Process p= Runtime.getRuntime().exec( cmd, null, new File( file.getParent()) );[/COLOR]

/*
String[] envp = new String[1];
envp[0] = "PATH = C:\\TC\\BIN";

Process p= Runtime.getRuntime().exec( cmd, envp, new File( file.getParent()) );

//has no effect
