You need to

collect the standard out/err from the Unix process and write into your JSP.
use Process.waitFor() to wait for the process exist and collection the return code. Otherwise you'll have a zombie process.

You need to read from the streams provided by the Process object returned by rt.exec() to capture the output. See this SO answer for more details.
