I am not sure of my facts here, but I believe that response.sendRedirect() may close the response. If you then attempt to write to the response afterwards, you get an IllegalStateException. Since your code is in a JSP page, this causes problems - after Tomcat has processed the scriptlet, it will continue over the remainder of the page and output it to the client - any HTML tags, new lines or even white space after the end of the scriptlet will be written to the response. This will cause an exception.
As someone has already stated here, this sort of code is much better suited to a Servlet. However, if you are looking for a quick and dirty fix, you could always add this HTML after the scriptlet:
<!doctype html public "-//w3c//dtd html 3.2//en"> <html> <head> <META http-equiv="refresh" content="0; URL=[ENTER PAGE HERE}"> </head> </html>
This will cause the browser to then request the new page which you specify. This is an awful way to solve the problem, but hopefully it helps...

Hello all. I've got a simple JSP page which is throwing an IllegalStateException when I try to redirect the output to another page. Here is a snippet of the code:
login = login.toUpperCase(); Connection myConnection = DriverManager.getConnection(url, login, password); String sessionId = session.getId(); Cookie cookie = new Cookie("sessionId", sessionId); response.addCookie(cookie); session.putValue("username", login); session.putValue("password", password); response.sendRedirect("rep_main.jsp"); myConnection.close();
I've searched through all the archives and never was able to find a solution to this for my case. One thing I did read was about having to have a "web.xml" file for my application (I currently don't have one nor know what to put in one). If you think this is the problem could you forward a simple/basic web.xml? Thanks in advance, Kenny
