Invalid Reference to Login Page.

If you're using form-based authentication in your Tomcat Application - you might've seen this error before:

Apache Tomcat/4.0.4 - HTTP Status 400 - Invalid direct reference to form login page

type: Status report

message: Invalid direct reference to form login page

description: The request sent by the client was syntactically incorrect (Invalid direct reference to form login page).

Well, the good news is - I figured out how to get around this today. Basically, it's caused when someone tried to go directly to your <form-login-page> to login, rather than a protected resource.

I use my index.jsp (welcome-file-list) page to do a redirect to a projected resource:

index.jsp
--------
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>

<logic:redirect page="/do/mainMenu"/%gt;

So I merely added the error-page declaration below to my web.xml, and whalla - no more error message!

<error-page>
<!-- 400 code is from trying to go directly to login.jsp -->
    <error-code>400</error-code>
    <location>/index.jsp</location>
</error-page>

If this doesn't help you - I don't know what will. You might try contacting support for your vendor's server. If it's Tomcat, I'd suggest contacting their mailing list.

OK guys, It is possible also to use this method for resolving our problem: To top login.jsp page you type: <% if(! session.isNew(){ session.sendRedirect("index.jsp") } %> Now you must to go web.xml file and type under login config(no important): <error-page> <error-code>400</error-code> <location>/index.jsp</location> </error-page>
