Hello, I have IOExeption when i use a process to
execute a System command such as dir/p or start
rmiregistry.What is the error message shown?
What can i do?? This is my code:
Runtime r = Runtime.getRuntime();
try {
Process p = r.exec("dir/p");dir is not a executable, it is a command to the shell, for NT try "cmd dir /p" and for 9.x "command dir /p" (and there goes your platform independence even withing windows :) )
Process p1 = r.exec("rmiregistry");make sure rmiregistry is in your path. to check it from command prompt type path.
Use a batch file (or just autoexec.bat) to add the path to rmiregistry in your path env variable before starting JVM.
} catch(IOException e) {
System.out.println(e);
