Runtime.getRuntime.exec() problem 2007-01-14 - By hui zhang
Back
Hi Everybody,
Now I am trying to launch an external application, for example, "top"
,in my web application, and killing it by PID after a while. But when I
execute Runtime.getRuntime.exec("top") in my JSP page or Servlet, Tomcat
is stuck in that page and do not display anything because it can not
stop running until that "commnad" is terminated, which means it waiting
for the response from Runtime.getRuntime.exec("top"). It seems that it
will run forever. Is there any solution to solve this problem? I mean
that JSP page can execute the following code no matter if it finish the
process is done.
BTW, I do not use System.exit() in my program. It may cause Security
Manager problem.
Thanks and best regards,
Hui
