JSP - Wait before redirect page

You might want to add some delay before redirect the page, instead of using sendRedirect(), which will redirect immediately, you can use response.setHeader() in JSP.

response.setHeader("Refresh", "5; URL=http://pandaeatsbamboo.blogspot.com/test.jsp")

You will then be redirected to the page after 5 seconds.

Redirect Page in JSP

Wanna redirect the user to some pages that you want to show? Pretty simple in JSP:

String redirectURL = "http://hostname.com/index.jsp";
response.sendRedirect(redirectURL);

JSP Execute shell script

Although there is security concern to do something like this, I might say that is convenient to do something like this instead of writing lots of complicated JSP pages to do simple system tasks.

Here ya go:

String linuxCmd = "./run.sh";
Runtime rt = Runtime.getRuntime();
rt.exec(linuxCmd);
