HI friends,
I'm trying to convert a pdf to an eps file using Ghostscript in my servlet. I have given a part of my code WHen I run the servelet,I'm getting an error =3 . I have spent hrs looking up on the web and I'm not sure what's wrong. Please help me and it urgent .

Note1: When I execute the command directly on command prompt. It works perfectly fine but when I call from my servlet , All I get is an empty eps file.

NOte2:StreamGobbler is a helper class(which extends Thread) I have created to read the proc.inputstream() and using PrintWriter class to write to the output file

Below is my code
/*****************************************************/
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {

String[] commands = new String[4];
commands[0] = "C:\gs\gs6.15\bin\gswin32c";
commands[1] = "-sDEVICE=epswrite";
commands[2] = "-sOutputFile=/TestProject/test.eps";
commands[3] = "/TestProject/test.pdf";
FileOutputStream fos = new FileOutputStream("c:\tomcat5.0\webapps\TestProject\test.eps");

Process proc = Runtime.getRuntime().exec(commands);
StreamGobbler errorGobbler = new
StreamGobbler(proc.getErrorStream(), "ERROR");
StreamGobbler outputGobbler = new StreamGobbler(proc.getInputStream(), "OUTPUT", fos);
errorGobbler.start();
outputGobbler.start();
int exitVal = proc.waitFor();
System.out.println("ExitValue: " + exitVal);
}

/***********************Output is **********************/
