Thanks for the heads up, was just going down that route.
I'm fine with using a regular html form, just not sure where to put
it. Twitter has a login form on their main splash page, which is
ideal. I am thinking I could do the same. My main page is already a
jsp page. I can do something like:
// myproject.jsp
<form action="myproject.jsp">
... login text fields ...
</form>
<%
String login = request.getParameter("login");
String password = request.getParameter("password");
if (login and password exist and are correct) {
startSession();
showProtectedUserInfoEtc();
}
else {
showGeneralInfo();
}
%>
this could work, the form just re-posts itself back to my main project
page. The downside is that I have to add the login logic on the main
page which is kind of ugly, but I think this will work correctly?
Thank you
