RE: howto configure JAAS+SSO
Hi Edmund. I am sorry but I don't know much about SSO. However I can tell you about JAAS in Tomcat. In 5 certainly there are issues. Essentially when you call the LoginModule to invoke your JAAS config it works but it does not authenticate the proper session Subject.

I'm trying to configure two webapps (slide and jetspeed2) for single-sign-on in the same tomcat instance. Both apps use JAAS and come with their own JAAS login modules. Is it possible to configure these (any?) two apps to share login info with JAAS. I started reading the JAAS docs recently and I tried putting the two login modules into one JAAS login context, but that does not seem to work, because the login module classes won't instantiate properly due to dependencies to their respective webapps. Can SSO be achieved without having the apps share one login context? Will I have to write my own login module(s)? Should I use a (completely) different approach to get SSO?

3. When you call youre LoginModule get the Subject and place in the session
and then write your own code to validate the Subject has the role required.
4. As for passing the session to your LoginModule, which I wouldn't do in a
puristic way as the LoginModule should be able to be used by a wing app just
as much as a web app.
Contstruct a CallBackHandler with the username and password but also with
the session or request. Then in your loginmodule you will have access to the
request/session when you invoke handle callback

I'm currently considering to write my own login module in order to share
authentication data across login contexts. i would need to access
session cookies from the module and i'm not sure how/if this can be done
yet.
i've never written a requestwrapper myself, so i can't really tell how
hard/complicated that would be. i'd be glad, if you could provide me
with some code to look at. that could certainly help me decide on how to
go on about that SSO requirement.

RE: howto configure JAAS+SSO
Hi Wendy, Sure I can explain what happens but not why. When you call the LoginModule with an optional Subject and CallBack the code works fine for me, i.e. it calls the LoginModule and I do everything I need, placing the Principals into the Subject. However... and this is where I don't want to say anything sweeping in case I have just simply misunderstood the Subject that is authenticated via the LoginModule has no visibility to Tomcat. If I could find a way to replace the session Subject with the one passed back from the LoginModule.getSubject() I would be ok, but I couldn't, so I placed the authorised Subject in the session and overrode the request.isUserInRole() to authorise against the Subject I placed in the session. One of these days I might ask the Tomcat dev list what I was doing wrong but got comments from other developers saying they had the same problem [All the JAAS examples do it the way I have described in some shape or form] Its not that bid a deal, and if you just use the Request wrapper I have attached you know that in the future you can remove the filter if you go to WebSphere or something like that. -Original Message- From: Wendy Smoak [mailto:[EMAIL PROTECTED] Sent: 16 August 2005 17:44 To: Tomcat Users List Subject: Re: howto configure JAAS+SSO From: Mark Benussi [EMAIL PROTECTED] However I can tell you about JAAS in Tomcat.

Last question on JAAS I promise
OK I got JAAS working with form authentication. That worked a treat (After a bit of head banging). I then moved to invoking the login from Struts (Or a Servlet for Tomcat users who don't use Struts) The code still gets invoked correctly. IBTJAASCallbackHandler callbackHandler = new IBTJAASCallbackHandler(loginForm.getUserName(), loginForm.getPassword()); LoginContext context = new LoginContext(IBTJAAS, callbackHandler); context.login(); However the request.remoteUser() is now null (Was populated correctly when I used form authentication) and the same for request.isUserInRole() (It returns false, even though the Principal was added to the subject). Any ideas...? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
My first JAAS implementation. A few questions.
I am implementing my first JAAS implementation and have some
problems/questions.
Firstly my commit method of my LoginModule does the following (User and Role
both implement Principal)
// Create a new User Principal with the user name retrieved from the
NameCallback
User user = new User(username);
// Add the principal to the subject
subject.getPrincipals().add(user);
for (int i = 0; i roles.length; i++) {
// Iterate the role names retrieved from the database lookup
String roleName = roles[i];
// Create a new Role Principal with the role name
Role role = new Role(roleName);
// Add it to the public credentials to see if it works
subject.getPublicCredentials().add(role);
// Add it to the private credentials to see if it works
subject.getPrivateCredentials().add(role);
}
return true;
In the JSP that the application returns to after doing form based
authentication the following occurs
pSubject = %= Subject.getSubject(AccessController.getContext()) %/p
pRemote User = %= request.getRemoteUser() %/p
pUser Prinicipal = %= request.getUserPrincipal() %/p
But this produces
Subject = null
Remote User = administrator
User Prinicipal = GenericPrincipal[administrator()]
Why is the subject null please?
The request.isUserInRole() methods for the role names I added to the subject
also return false... has anyone got some helpful ideas please?
If more source is needed I can gladly provide it if will help

Tomcat 4.1.37 and 5.0.2?? differences
I am having to change my ISP and was wondering what the main differences were with these two servers. Are Servlet filters supported and more importantly what J2EE does it typically run on? TIA to the legend list that is making my nightmare week a bit better.

RE: Version issue in coding
Well without wishing to sound petty Your development environment should replicate you server environment as closely as possible.

OT Friday - Random sorting
Hello.
I am trying to write a comparator that randomly sorts a collection.
I have something like this:
new Comparator() {
/**
* @see java.util.Comparator#compare(java.lang.Object,
java.lang.Object)
*/
public int compare(Object object1, Object object2) {
long time = new Date().getTime();
Random random1 = new Random(time);
Integer x1 = new Integer(random1.nextInt());
random1.setSeed(++time);
Integer x2 = new Integer(random1.nextInt());
return x1.compareTo(x2);
}
}
But sadly to no avail.
Has anyone done this before or have any suggestions.

RE: Client Authentication certificates
Thanks Philip.. ever so much help. I really appreciate this! -Original Message- From: Philippe Johan [mailto:[EMAIL PROTECTED] Sent: 24 May 2005 08:55 To: tomcat-user@jakarta.apache.org Subject: RE: Client Authentication certificates Hi Mark, To answer your questions: - You can create your own Certificate Authority (CA) with no links to any other certificate, institution,... A typical CA certificate is just that: a self-signed certificate (=signed with the private key matching the public key contained inside the certificate). - Client authentication is part of SSL. It is during the SSL hand-shake that the server will request the client certificate. So the short answer would be: NO you can not implement this without SSL. - The CA the server requires for the client certificates can be completely unrelated to the server certificate. So I think your ideal solution would be to have a standard (i.e. Verisign) server certificate, but your own client certificates with their own CA (the one you created yourself). To implement this, your keystoreFile (containing the server and matching CA certificate) will be different from your truststoreFile (containing the client CA certificate). If you go with the really cheap option to create the server certificate yourself as well, you will indeed have the issue mentioned below. But do know that this CA certificate is typically automatically added in the browser store during the generation of the client certificate. Meaning that if 100% of your clients will be accessing this server with a client certificate this is not an issue. Have a look at EJBCA (Enterprise Java Beans Certificate Authority http://ejbca.sourceforge.net/) for the certificate management part. Distributing certificates, and more important the matching private keys, is not an easy thing to do with the OpenSSL command-line tools.

[OT] JSP custom taglib issue in duplicate environments
I have two environments with the same mysql DB, both running the same war on tomcat 5.0 and I have a problem which I can only think may lie in my JSP taglib and its extra info. Essentially I call a tag three times in the same page, and depending on taglib arguments the tag should display data between only one of the tags. Instead on my live environment it's doing it at all the stages, this is driving me barmy and if anyone has any experience with a similar problem please let me know. I can provide source if anyone wants to help me get my hands dirty. I almost fell like I should be flushing my taglib after my doStartTag() as it seems the data is being left in the page (My VariableInfo is all nested). Yours desperately...

RE: Dynamic to static conversion
Hi Dola, A strategy you could employ is the following. All data for your items can be held in a persistence store of some kind (DB, XML). For each product build an XML representation and then use XSLT to convert each item to a html file. Then when requesting to view an item you can build up a Struts template (Or whatever technology your prefer ;o) ) and insert the static file, wrapping round it all your dynamics (Shopping cart, account details etc). When ever an item is updated you can simply redo the translation. An added benefit is that if you wish to search the content you have static html files you can search using Lucene (Or whatever technology your prefer ;o) ) and you know you are only searching the content, not any of the 'wrapping' of a page. I have used this strategy for my sites and it is very inexpensive in so far as the html for the item is done for you. No runtime presentation logic is required. -Original Message- From: Dakota Jack [mailto:[EMAIL PROTECTED] Sent: 29 April 2005 14:48 To: Tomcat Users List Subject: Re: Dynamic to static conversion There is no reason I can think of to build static pages dynamically.

If you don't want your thread to run in the same JVM as Tomcat, you can send a message to a daemon; then the daemon (in another JVM and/or another server) will receive the messages and treat them (in new Threads). To send messages, you can use JMS (so, you need a JMS server) or sockets TCP or UDP (see java.net). Basically what the thread does is email people to notify them of a change in an order on the system. I want the emails to be sent in a separate thread so that the user doesn't have to wait for this to complete to return to the system. Basically the email is a non crucial part, the action has already been performed. I know this isn't specifically a Tomcat question, but I thought I would ask it anyway. The two ways this could work is that the email is placed in a queue, that is checked periodically, or just somehow the email(s) are sent in the background, but without opening a new thread using code. Can anyone give me some pointers on how to do this. Yes I have been searching around, but haven't found much information.

RE: caching pattern
If you are caching content, e.g. pages I would recommend using XSL to transform the data into html, or jsp if you need. At startup and then whenever it is changed. For data, implement a persistence pattern (Data extends BaseData class, Persistence extends BasePersistence class). Then for any data you want to cache extend the BaseData to override the CRUD methods to hold data in a Hashtable by key lookup (Assuming your data can be looked up using a single key).

RE: AW: Getting other Sessions
You need to implement a Session Listener like this.
public class SessionHelper implements HttpSessionListener {
private static Hashtable sessionsById = null;
/**
* @see
javax.servlet.http.HttpSessionListener#sessionCreated(javax.servlet.http.HttpSessionEvent)
*/
public void sessionCreated(HttpSessionEvent sessionEvent) {
if (sessionsById == null) {
sessionsById = new Hashtable();
}
HttpSession session = sessionEvent.getSession();
String sessionId = session.getId();
sessionsById.put(sessionId, session);
}
/**
* @see
javax.servlet.http.HttpSessionListener#sessionDestroyed(javax.servlet.http.HttpSessionEvent)
*/
public void sessionDestroyed(HttpSessionEvent sessionEvent) {
}
}
Then you can access the sessions via this session helpers Hashtable.
Finally you need to add the following to your web.xml.
web-app id=WebApp
display-nameblah/display-name
listener
listener-classSessionHelper/listener-class
/listener
.. etc

Mark

RE: 24X7 deployment tips
Hi Sunil, I think they keyword for your scenario is clustering. Running multiple syncronised applications and databases allows you to take down servers during quiet periods and still maintain a service via the other servers whilst they are upgraded one by one. Saying that I have worked on global .coms that always allow for some down time during large releases / maintenance. It is not going to be easy but I am sure you appreciate that. One more thing that may cause a headache is session persistence under some Tomcat clustering models. Thats all i can think of but i'm sure you will get better advice than mine.

Sorry what I mean is that the methods implemented for the HttpSessionListener do not get called when I invoke a new session.

Re: HttpSessionListener Interface - Mail Archive not workingsoapologies for repost
Hi Ben,
I have not extended httpservlet, I don't see why I would have to do this?
package helpers;
import javax.servlet.http.HttpSessionEvent;
import javax.servlet.http.HttpSessionListener;
public class SessionHelper implements HttpSessionListener {
public void sessionCreated(HttpSessionEvent sessionEvent) {
int x = 1;
// Not called
}
public void sessionDestroyed(HttpSessionEvent sessionEvent) {
int x = 2;
// Not called
}
}

You've extended HttpServlet, implemented HttpSessionListener, and the
code in the sessionCreated(HttpSessionEvent event) method is not being
called when you create a new session?
Can you post your code?

Re: HttpSessionListener Interface - Mail Archive notworkingsoapologies for repost
Solved.
For any of you using Websphere Studio to attach and debug a remote Tomcat
instance be warned. The line numbers seem to be one out on my class and it
worked when I put more than one LOC and a few more debug points (As well as
some logging thanks Ben ;) )

You don't... sorry (was still on first cup of coffeee ;))
You've tried putting println statements in the sessionCreated and
sessionDestroyed methods to verify that they're not being called?

I woud like to give you an answer but I experienced similar problems accessing my localhost via IP when using a router.

Securing directory: httpd vs tomcat configuration
Hi I need to secure two directories with a user name and password prompt. Just one is fine at the moment. I know I can do this using httpd but I was wondering if there was a better solution for Tomcat (5), i.e. by configuring something in the server config or web.xml. If anyone has a solution I would be really appreciative. Thanks. Mark - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Installing the MySql jdbc driver on XP?
Use mysql connector for your jdbc connections and place the jar in the $CATALINA_HOME/common/lib. In terms of using it in your lightweight code, you will have to describe your development practices... are you using an IDE? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Installing the MySql jdbc driver on XP?
If your using eclipse just place the mysql connector jar in your projects jar list... there are many examples of using DriverManager... search the web. Sorry I cant be of more help but my code uses connection pooling and you need to find and understand the use of DriverManager in its most basic form.
