So, name your context configuration file context.xml and put it in the META-INF directory of your .war file. Now do the upload and your context information should be there. Currently, given an application called, say drs, I provide a file called drs.xml that sits in webapps. This contains the Context/Context part of server.xml.

Re: Tomcat: j_security_check: Form Authentication
Muhammad Bilal wrote: I want to have a synchronization between the authentication stuff. Like, I have a web site, and every user has some role, and every user can access some protected resource based on his role. Now I want to use JDBC realm for this purpose with Form auth. so that user logs into the site only once and use it according to his access rights, instead he requests for a protected resource and then he goes to login page. You see, its quite logical that user should have a leverage to go to login page first or to access a protected resource. If things work for him in latter case why not in former? I believe there must be some thing to do it, after all tomcat's default admin site is doing the same thing. It doesn't! The link to the admin app is /admin/index.jsp - this is a protected resource, so the user is redirected to the login page /admin/login.jsp. Once authenticated, he then sees the page he originally requested. The problem is that if you enter /admin/login.jsp directly, you get an error when you submit the form. So, the general problem is that it is not possible to bookmark the login page, unless there is a subtle work-around that I haven't come across. However, if a user bookmarks a protected resource (or is given a url to a protected resource), he will be asked to login the first time he accesses that page in a session. Thereafter, he can navigate directly to any page which matches (one of) his assigned role(s). HTH Martin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Does anyone knows all this internal action, how it is going on? Comments, URLs appreciated. Info: I use Postgresql if it counts. In the case that I will have to not return the connection to the pool, and, because ResultSet doesn't hold in memory all the records I would save it int the HTTPSession, HOW AM I going to know when to release it and return the connection to the pool? In this case, I would query the database initially, asking ONLY for the unique id of each row (or the master row if there's a join involved). I would then cache the entire result set, and then fetch the complete records subsequently, by doing something like: SELECT whatever FROM mytable WHERE oid IN (oid1, oid2, oid3, ...); Of course, you'd have to handle the case where a cached oid is deleted between the initial query, and the later one. If the unique id (oid in my example above) is an integer, you can cache the entire database in 4Mb.

Restarting apache cures the problem. It is occasionally possible (randomly?) to access the new servlet without a restart, but mostly not. The symptoms seem to imply to me that only new WARP connections created since the redeployment are able to access the servlet, whereas connections that had been existing prior to it get confused and can't see the newly redeployed servlet. Has anybody else noticed this behaviour? Is it a bug in mod_webapp ? This is what I would expect to happen; AFAIK, mod_webapp, mod_jk etc. all create socket connections to Tomcat. In order to re-deploy your web app, Tomcat stops and restarts the context, which closes one end of the socket. Therefore Apache has to be restarted in order to reconnect to Tomcat properly.

Re: [classloading] How to use URLClassLoader within a servlet
Ola Berg wrote: I have this problem with using my own (URLClassLoader) class loader in a servlet of mine. The thing is that I am writing a web front end to domain name services (automatic registration of .org, .com. .biz, .info etc domains). Depending on the top level domain, I need to use different versions (jars) of the same API, since the protocol differs. So I need to dynamically load my classes at runtime. Just putting the jars in lib won't work since there are different implementations of the same classes in them. I have to decide in runtime. Using the URLClassLoader in a standalone app works perfectly, when using it in a servlet it just hangs. I suspect the problem lies within the different lookup order used in servlets (as dscribed in the classloader-HOWTO). I can't figure out how to do it. Has anyone experience in the field? I have an analogous case, in which I have a single API for database access, with choice of database (Oracle, MySQL,...) made at run-time. The problem was simply solved using the 'Abstract Factory' pattern. This means that I have two packages (db.MySql, db.Oracle), which both include an implementation of a DBFactory. I then use ClassForName() to load the appropriate implementation, and then call factory methods to instantiate the appropriate classes. Hence, you don't need to bother with custom classloaders, and your design is much 'cleaner' as a result.

Actually, it sounds like you may be past that part already. The one hurdle I had in the whole process (not in the article) was caused by StuffIt! when it unzipped the download. The filename for the class SetCharacterEncodingFilter.class is too long for StuffIt! so it drops the ss off the end. Now the JVM doesn't find it and you get an error page instead.

Re: App Initialization question
[EMAIL PROTECTED] wrote: Hi, I need to store an object in the application context and this object has to be instatiated when the application is deployed. I am thinking about a solution but I would like confirmation that it is a good practice to do : - declare a servlet that would have a load-on-startup element in web.xml - implement the creation of my object in this servlet - store the generated object in the application context The point is that this servlet would be used only for that purpose (initialization) and I guess there may have some more standard way to do so. Can someone confirm that this is the way to do or point me to a better solution ? Generally, using a servlet with a load-on-startup element is NOT the best way to go about it - the servlet spec allows servlet containers to instantiate and trash servlets at any time. Hence, your servlet might be instantiated several times, and your initialisation code executed several times. The preferred method is to define a class that implements the ContextListener interface, and to perform initialisation code in the contextInitialised() method. Cleanup can be done in the contextDestroyed() method. I use this to load a bunch of application properties from an external file into a singleton class, MyAppProperties. The servlets then just do MyAppProperties.getInstance() to get the instance of the class. It works great!

SSL, JK redirect question
I have tc4.1.12, Apache 2.0.43 mod_ssl and mod_jk set up and working successfully on my Mac (OS X 10.1.5), but tweaking the Apache config to get it to work was... involved, let's say :-) Users enter the site (using http: protocol) at /drs/home. This contains a button labelled Login that takes them to /drs/private/home. Because /drs/private/* is under a security contraint, it triggers a redirect to /drs/login which POSTs to j_security_check, etc. Previously, using tomcat-standalone, the transport-guaranteeCONFIDENTIAL/transport-guarantee triggered the switch to https: - however, this no longer works when Apache/mod_jk are in the loop. Because /drs/private/* isn't accessible via http: I was getting an Apache-generated 404 error when the login button on the home page was clicked: the solution I found was to place a Redirect /drs/private/home https://host/drs/private/home in httpd.conf Of course, this gives an extra redirect, and seems inelegant...does anyone have a better solution?

Re: Defining methods in JSP pages
Craig R. McClanahan wrote: The biggest problem with the general approach you suggest is that you are mixing Java logic into your pages, which means you need a Java programmer to maintain them. A much better strategy is to use a model-view-controller (MVC) style architecture that has back-end business logic setting up the dynamic things your page needs in request attributes or session attributes, and then forward to the page (which can use things like jsp:getProperty to grab them. An example of a framework for MVC style development is Struts http://jakarta.apache.org/struts. An additional benefit of banishing scriptlets from your pages is that the JSP page compiler can generate better code, as well as handling bigger and more complex pages. The general trend in modern JSP development is away from scriptlets. Another solution (which I use) is to not use JSPs at all - just servlets with the Velocity template engine http://jakarta.apache.org/velocity.

might be.
The server.xml parameters are correct (they didn't change!), and keytool

security upgrade I recently applied to Mac OS X, but before I post a bug

reproduce it in a simple test class, so any help identifying the
offending method call will be greatly appreciated!

HAVENS,PETER (HP-Cupertino,ex3) wrote: I am using form based authentication on my Tomcat 4.0.4 server and I am trying to figure out how to set up a security constraint that would apply only to the login page. My global web.xml has a security constraint that points to a login.jsp page as the form-login-page. As I understand it, the global web.xml can only have one security-constraint. What I want to do is configure this login.jsp page to be served up via HTTPS only. This way users will not be submitting password as plain text. I know about using the user-data-constraint transport-guarantee, but I do not want to require SSL for all pages, just the login page. Is this possible? I don't know whether this is possible - I tried for a while, thinking like you that it was sufficient to protect the login page, until I Saw The Light. If you only protected the login page, then although the user's password would not be sent in clear, the session id on subsequent pages would be. Since a hacker only needs the session id to masquerade as your logged-in user, you MUST encrypt the entire session after login. This is what the servlet spec mandates, and what Tomcat does.

Re: form-login-config

If you look at slashdot.org they do a similar thing with a member login on each page in the right column - it's doesn't take up too much real estate. When I figured out how the form-login-config worked I realised I could of course do it like you were suggesting, however I really would like to get it working as is ideally - as that's how the html designed it. Any other suggestions? Hmm, tricky. Let's imagine that your login form posts to the member home page. Then, tomcat would re-direct to your login servlet. If this servlet had access to the user id password fields already posted, then you could simply pass them directly on to j_security_check. The trouble is, I don't know whether this information is available, nor how you might access it, and I don't have time to RTFM for you. :-) If that doesn't work, then I suggest you write a filter that goes in front of every member page; this would either check that the user had already logged in, or would validate the login parameters.

Richard Chamberlain wrote: After I sent my previous message I played around a bit and it became clear that I was misinterpreting how to use form login. I'll explain what I want to do and perhaps somebody would be kind enough to point me in the right direction. I have a page that I only want members to be able to get to, member.jsp for instance. At the moment I've got it set up so attempting to access member.jsp will redirect you to the index page at which point you can login in and then be redirected to the member page. All works ok. However what I actually want is a form login on each page of the site and when a user logs in they get redirected to member.jsp. At the moment that gives me a invalid direct reference to form login page because tomcat wants me to go to member.jsp first and then be redirected to a form. Do I have to write myself some authentication code in this case? This was very easy in resin because you just mapped the j_security_check servlet and everything worked as I've outlined. Do you mean that you actually have the login form embedded in every public page? Doesn't that clutter up your pages unnecessarily? What I do is to have a Login button on every public page. The login button sends the user to the private home page. Since this is subject to a security restriction, the user is diverted to a login page first. Once logged in, he is automagically redirected to the private home page. This works well!

Here is what the Tomcat how-to on that says: This document describes how to configure Tomcat to support container managed security, by connecting to an existing database of usernames, passwords, and user roles. You only need to care about this if you are using a web application that includes one or more security-constraint elements, and a login-config element defining how users are required to authenticate themselves. If you are not utilizing these features, you can safely skip this document. I should say that I am doing this in a verbose fashion in the hopes that other OS X users will be able to find it with google when/if they need it. My similar query at http://forums.osxfaq.com/viewforum.php?forum=15 has had 3 hits (one of which is mine) in the same time span as this post here; here there have been responses of great value to this inquiry, there have been none elsewhere. Now, do I need container managed security? Did you? Or was that an approach that happened to get your installation working in absence of other considerations? In a reply here by Steve Ahlstrom, he does not appear to use JDBCRealm, but does use a greatly expanded Context... entry in server.xml, and additional information (compared to what I use) in his application's web.xml. Security in my program has, all along, been handled by authentication routines built into my code (though I can imagine handing that work over to something else in the future). I configured container managed security simply because the application requires it. I used it as an example because my application code accesses the database via a connection pool and JNDI, so it's more complicated to explain. In another (later) post, you describe your Unix accounts; mine are somewhat different. In case it helps, I'll describe them... First, I'm an old-time Unix guy (SVR4, Solaris, Linux), but I don't know the ins-and-outs of BSD, nor NextStep, so I didn't know about sudo when I started hacking about. I enabled root in NetInfo, and made sure that my user (martin) was a member of a group that root was also in. Hence, I was able to su root. I created a login account for mysql, and installed mysql as per instructions. I created a mysql user 'tomcat' which can only perform selects on one database. Also, tomcat can only connect from 'localhost' or 'macx'. I created another account which can do anything on the same single database when connecting from 'localhost', and this is the account that the application code uses. To run tomcat, I cd to the base directory, su root, and type bin/startup.sh - this is because I use tomcat in standalone mode, and use ports 80/443. I suggest (if you haven't already done so) setting debug=9 everywhere(!), and then post the logs, with any relevant server.xml, web.xml and code snippets.

To re-iterate the problem: I use Coyote to configure a SSL connector, which *apparently* correctly initialises itself (I checked that something was happening by removing certain parameters, and it then barfed). However, when I access a protected page, the re-direct to my login page (which uses ssl) fails with a java.net.MalformedURLException, which indicates that there is no stream protocol handler registered for 'https'.

You need JSSE for that to work (and put the JARs in common/lib, or use JDK 1.4). There is a bug in that release recognizing the keystoreType attribute, though (bugzilla 9676). This got fixed in release 4.1.4. Remy Well, I already had JSSE installed as a standard extension, but I copied it to common/lib anyway; there was no difference, I'm afraid :-( I should point out that I have this working (not with Coyote) in Tomcat 4.0.4, if that helps.

Re: front controller pattern and security
John Gregg wrote: Hi all. I've been thinking about how the j2ee front controller pattern (used by Struts et al.) does/does not take advantage of url-based authorization constraints in web.xml. I want to avoid having to check roles in my own code as much as possible. At first I thought I could declare a URL like /somewebapp/somerole/* to require the somerole role before being allowed access to my controller servlet. Another URL would be /somewebapp/someotherrole/* but would map to the same servlet. That servlet would then pick off the action at the end of the URL and execute it. However, while I can restrict access to the servlet, or whatever other physical resource I'm trying to protect, what I really want to protect is the action that's executed. Am I just stuck with enumerating all possible actions in by web.xml (/somewebapp/somerole/someaction, /somewebapp/somerole/someotheraction, etc.)? Should I instead make a filter that enforces this for me? I'm facing the same problem with Apache SOAP's rpcrouter. Surely, the way you describe, using servlet-mapping auth-constraint does exactly what you want? In other words, you have one (controller) servlet declared, and you use servlet-mapping to declare all urls that invoke that servlet. In auth-contstraint you declare the mapping between urls and user roles. So, when a user invokes /app/manager/ac_details, the auth-constraint would trigger an authorisation check to make sure the user was in the indicated role. Then (if he's allowed), because the servlet-mapping maps this url to the controller servlet, the controller servlet is invoked, and, as you say, you can then determine what the action was (ac_details) by examining the url. This method does not restrict access to the controller servlet directly, but does protect the functions to be performed. Or have I misunderstood?
