Message:

Method getRuntime().exec

Posted by Alex Friedman on August 16, 2001 at 1:12 AM

Hi I'm trying to execute a jar file from another java program. But for some reason this doesnt work.
try{
Runtime.getRuntime().exec(
"c:/pathname/java.exe -jar MyPgm.jar");
}
catch(IOException ioe){ioe.printStackTrace();}

the above code just opens a dos window and quickly closes it.
When i try executing that string in windows run it works but for some reason out of my java program it doesnt. Anyone know why??
thanx
