Servlet reload problem
Dear all, I am using Tomcat 1.4.27 and each time after I made some modification to my servlet, tomcat didn't reload the updated one. By the way I already installed the hot patch that is said to solve the reloading problem. Any ideas? Thanks in advance. - Do you Yahoo!? The New Yahoo! Shopping - with improved product search

RE: Send mail cgi script doesn't work under tomcat?
Patrik, So I am not alone. Here are the possible soultions I came up with, hopefully they help. 1. If just a few cgi scripts and they are simple, port them to Java. 2. Integrate Tomcat with Apache, then you don't need to modify the cgi scripts. However, the server configuration becomes more complicated. 3. Hack the useCGI servlet, I am not sure this works. 4. Just port the email portion to java and write it as a filter servlet, which postprocess the requests after your CGI. (This is the one I would like to try but did not try yet).

form login page does not appear for my custom authenticator?
Dear all,
I had a wierd problem working with my own authenticator. The form login page did not
appear at all but I got an error message stating Configuration error: Cannot perform
access control without an authenticated principal. By checking the log file, I
understood how this error was triggered but still could not solve it.
Since the login page did not appear, I had no chance to invoke j_security_check (by
clicking the submit button). Consequently the request url did not end with the string
j_security_check. Somewhere in the program, the following check thus failed.
// Is this the action request from the login page?
boolean loginAction =
requestURI.startsWith(contextPath)
requestURI.endsWith(Constants.FORM_ACTION);
// No -- Save this request and redirect to the form login page
if (!loginAction) {
session = getSession(request, true);
if (debug = 1)
log(Save request in session ' + session.getId() + ');
saveRequest(request, session);
if (debug = 1)
log(Redirect to login page ' + loginURI + ');
hres.sendRedirect(hres.encodeRedirectURL(loginURI));
return (false);
}
So I was redirected to the login page (again it did not appear at all). This time the
following check succeeded:
// Is this a request for the login page itself? Test here to avoid
// displaying it twice (from the user's perspective) -- once because
// of the save and redirect and once because of the restore and
// redirect performed below.
String loginURI = contextPath + config.getLoginPage();
if (requestURI.equals(loginURI)) {
if (debug = 1)
log(Requesting login page normally);
return (true); // Display the login page in the usual manner
}
I think this code assumes I have been already authenticated. That's why finally I got
the error.
My questions are:
1. When should the login page appear? I think it should appear before the call of the
corresponding authenticator, am I right?
2. Is there some special configuration to bring up the login page for user's custom
authenticator?
Any suggestions or hints would be greatly appreciated.

Re: Filter for Form Authentication Problem

What are the consequences/possibilities to set the request character encoding with servlet standard API mechanisms instead of using the Tomcat proprietary solution of using a Valve? This is a really interesting issue. I would hope that you would send a message to [EMAIL PROTECTED] to hopefully get the expert-team to clarify this before the 2.4 spec goes final. Because the Servlet-2.2 spec lacks the request.setCharacterEncoding method, Tomcat 3.3 jumps through a lot of hoops to try and guess the charset. These were dropped in Tomcat 4+, since the request.setCharacterEncoding method was supposed to solve all of these problems. As you have pointed out, it is not possible to use this in a Filter for the standard Form-auth config (for the simple reason that Auth is called before Filters). Therefore, the j_security_check target is flying blind wrt charset. Joerg Lawence wrote: Dear All, I wrote a filter servlet that does some preprocessing.
