To John B. Matthews, If I call PDF Creator from the cmd line directly
(not through JAVA) it gives the required o/p. But I'm invoking a Java
function through JSP which executes the PDFCreator.exe through cmd
line it doesn't work. cmd.exe it invoked as I can see it in my Task
Manager, but nothing else happens.

Have you inspected the compiled JSP to see if the command is
processed correctly?

Browsing the relevant help file and looking at the /PF section,

<http://pdfcreator.svn.sourceforge.net/svnroot/pdfcreator/trunk/Help/english/html/commandline.htm>

Code is:
public void print() {
String cmd="C:\\WINDOWS\\system32\\cmd.exe /C C:\\Program Files\
\PDFCreator\\PDFCreator.exe /NOSTART /PF
\"C:\\Program Files\\Apache Software Foundation\\Tomcat 5.5\\webapps\
\Reports\\1.doc\"";

I presume that the path is correct and that "There is NO space
between the parameter and the file name."

try{
p = r.getRuntime().exec(cmd);

stdInput = new BufferedReader(new InputStreamReader(p.getInputStream
()));
stdError = new BufferedReader(new InputStreamReader(p.getErrorStream
()));
System.out.println("Input="+stdInput);
System.out.println("Error="+stdError);
} catch(IOException ioe){System.out.println("Exception="+ioe);
}

The PDF creator is executing but does not give any o/p.
Im using thesame command as given in help file of PDF Creator.

Perhaps I'm overlooking it, but I see nothing to suggest that anything
will appear on standard output. Have you tried the /IF<input-filename>
/OF<output-filename> options?
