How to perform a forced reload of Tomcat ?
Hi, I am using Tomcat 4.1.18 , j2sdk 1.4.1, win2k. It is a remote server physical access is very limited. I am using it as the development server. Two developers are using the same server. The problem is if by mistake the enter key or the refresh key is kept preseed or if a database lock is engaged Tomcat will stop responding. Actullay Tomcat is running. The browser reports web site found waiting for reply. But no page displayed.If I try to reload the page through Tomcat manager app it also hangs. No response from Tomcat. In such situations how to force a reload by killing all the threads ?. I have a setting of minProcessors=2 maxProcessors=20 in the server.xml.

Tomcat Web Application Manager + static variables
Hello,
I have a question about Tomcat Web Application Manager.
Suppose I have static member in a simple class
public class xxx {
public static yyy zzz = new yyy();
}
I load my web application and everything is fine. But
when I reload my whole application using Tomcat
Web Application Manager zzz contains the same instance
of yyy as before reloading. Is it a bug of TWAM?
Best regards

Re: Tomcat Web Application Manager + static variables
Search for Singleton in the archives.
Do you mean the /manager/ webapp? It doesn't hold on to instances of
anything. (AFAIK)
For singletons to work correctly - make sure the classese live under
WEB-INF/[lib|classes]. Each webapp has hits own classloader. On a reload, the
old classloader is dumped and a new one is made. But the archives have many
converstations about Singletons sounds similar to your issue.

Re: Client Certificates Authentication in Tomcat v4.1.24
Hi Bill Everyone else, For JSSE, you need to have the signer in cacerts at the moment for Tomcat to include it in the list of signers it wants. PureTLS allows you to configure the list (without being root), but other problems mean that you can only use it in TC 5 HEAD at the moment. Of course, the Tomcat support for CLIENT-CERT is pretty minimal at the moment. Only the (deprecated) MemoryRealm supports it (unless you write your own Realm). Thanks for the information regarding the cacerts file and JSSE. After checking the configuration, I discovered that I was missing the cacerts file and have installed it into the proper directory under the $JAVA_HOME/lib/security directory hierarchy. Unfortunately, this didn't change anything, as IE is still popping up a blank box for me to select my certificate. Does the CA certificate have to belong to any particular alias for JSSE to work. I have tried installing it as -trustcacerts and a normal import into the alias root and tomcat without any success. You don't need to do anything special to get the root CA into the keystore do you ?, I am simply taking the CA certificate as a .pem along with the key, converting them to .der and then doing an import. Do you happen to have any more ideas as to what is happening here or how I might be able to resolve it ?, I am quite happy to send a copy of the commands I am using off the list so that you can see the process that I am going through.

Re: Deploying a WAR
Hi, Christian WAR-Files just contain Webapps (ok, almost :P). They don't need to be started like you tried. IMHO you have a war file called orange.war which contains all possible files you need AND A WEB-INF directory? Then you can simply start it by typing the name of the war file at the end of the url. Assume you have a url like http://vredungmand.dk/programming/orange/. In the orange directory you have copied the war file? Then this is your url: http://vredungmand.dk/programming/orange/orange This should invoke Tomcat to unpack the war file, create within the orange directory a new directory orange and unpack any files from the war file into this directory. TC should present your welcome page you have defined in web.xml in orange/WEB-INF/ after that. Oh yes, I almost forgot: in TC's server.xml your Host declaration should contain the parameter unpackWARs=true. And within the Host section you shouldn't have a Context declaration for that directory/webapp. Best regards Dirk Christian Hvid wrote: Hi.

invalid direct reference to form login page...
Hi all, I've set up Tomcat (4.1.24) to do form based authentication. Everything works great, except I've had to deal with a lot of users that type in the url I've given them, get redirected to the login page, and bookmark the login page before logging in. Later, when they use the bookmark, they get sent to the login page, but get a Invalid direct reference to form login page... message once they log in. I understand why this happens, but don't know what to do about it. Is there a way to specify a default page to go to when the login page is requested directly?

RE: invalid direct reference to form login page...
Your problem has just recently been discussed on this list. Ben Jessel
proposed a workaround which I attached below. Hopefully, this might work for
you.

Subject: Possible workaround for invalid direct reference to
login page
Java Authentication with tomcat relies on realms. If you
access a page
protected by that realm you get directed to the login page.
However, it is possible to go directly to the login page (
this can happen
when users bookmark the login page inadvertantly ).
This happens in two scenarios:
1) The user is already logged in.
2) The user is not logged in.
If you authenticate yourself once you have gone directly to the login
page, you get a invalid direct reference error. Fair
enough, the login
page is trying to redirect to itself. Now, I tried to
workaround this by
checking if the session is null, and if it is, redirecting to some
protected page, eg. protected/index.jsp. No luck. It seems
that a session
is implicitly created, and a new session id gets created.
So I've tried a cookie strategy:
%
if ( request.getCookies()==null ) {
response.sendRedirect(//jsp/protected/index.jsp);
}
if ( request.getRemoteUser()!=null )
{
response.sendRedirect(/x/jsp/protected/index.jsp);
}
%
i.e, we wont have a cookie if we've gone directly to the
login page. But
we will have if we've tried to access a protected page and
then we've been
forwarded to a login page, tomcat will give us a cookie.
Now if we're already logged in ( which we check with
getRemoteUser() ,
then we just forward to user to an index page.
This seems o.k. However my index page actually includes my
login page! I'm
planning to get around this with some logic that only
includes the login
page excerpt if we are not logged in..

Tomcat Installation/Configuration using Ant
Hello, I am trying to write an Ant Script that would allow me to install Tomcat using an Ant script. The reason I am planning to do this is because it will allow me to control the set up of different program through Ant and automatically configure them. Now When I looked at the tomcat installer program, it has number of options in terms of what packages you wanted to install. I am wondering is it documented somehere (or can I find out from somewhere) on what this install options(Tomcat, JSP Development Shell Extension, Tomcat Documenation, Example Web Application) maps to in terms of directories so that I can control this from my Ant scripts. Also, I am assuming the port info, login info the installer asks get put into server.xml file. Is that correct. Any help in this regard would be appreciated thanks Sushil

All I had to do was upgrade my Tomcat installation from the 4.0.1 version which comes with Java Sun One Studio (and is still being distributed at the Java site, huh!) to Tomcat 4.1.24, which at least is a stable release! I don't know why Java is still distributing j2sdk-1_4_1_02-s1studio_ce-4u1-bin-linux.bin with Tomcat 4.0.1.
