Hi am getting the following error.

public static void RunExe()
{
String st = "";
st = "/bin/sh.exe C:/convert/runshell.sh";
try
{
Runtime.getRuntime().exec ( st ) ;//error here
}
catch(Exception ex)
{
ex.printStackTrace();
}
}

java.io.IOException: CreateProcess: /bin/sh.exe runshell.sh error=2

(You need the right path to sh.exe)

sciuriware

If you are on linux/unix, then

String st = "/bin/sh.exe /convert/runshell.sh";

will work, provided that the script is in /convert ...............

sh.exe should be in your path so you could try:
String st="sh.exe /convert/runshell.sh";

sciuriware

Again: only when /convert is on your current disk!
Test with FULL pathnames!

Unlikely with a .exe extension ;-)

>>sh.exe should be in your path

Why so?

Try this to verify everything:
public static void RunExe()
{
File sh=new File("/bin/sh.exe");
File script=new File("c:/convert/runshell.sh")
if (sh.exists()==false) {
throw new FileNotFoundException("Command shell (sh.exe)");
if (script.exists()==false) {
throw new FileNotFoundException("Shell script(runshell.sh)");

String st = sh..getAbsolutePath()+" "+script..getAbsolutePath();
try
{
Runtime.getRuntime().exec ( st ) ;//error here
}
catch(Exception ex)
{
ex.printStackTrace();
}
}

getAbsolutePath is not necessary - both paths are already absolute

"/" means root of the drive where your java app is executed. Try copying java class to the drive where sh.exe is, and things should work fine. Otherwise you'll have to specify full path like "C:/.."
