Using Runtime exec() to open java on other directory

843798

HI, I have a little problem and i hope everyone can help me out abit. You see when u use Runtime.exec(), how to you use it so that when the file you want to open is different from your program directory.
For example,
my program is in c:\windows\desktop
but the file i want to open eg. Somthing.class is in c:\my documents\
How do I open it using java and i wish to open the file using the java command. Thank a million

Hi,

You can try something like

Runtime.getRuntime().exec("cmd /c start /d\"C:\\my documents\" java.exe Somthing");

Hope this helps,

Kurt.
