I am trying to build an application where I hit a button from a
jsp page, sending me to a
servlet that uses runtime.exec to run a sql query on the server, then return the results to be displayed on the same page. Right now, i call proc.runtime.exec("get data"), then proc.waitFor(), then I forward(request, response) to the original page. Right now, this is working when i call runtime.exec on a very fast command, such as "pwd," but it is not working for my command which takes slightly longer to run - it redirects before the process has finished. Shouldn't waitFor() let the process terminate before forwarding the request? If not, are there alternatives I should be using?
