Re: ldap authentication with tomcat
Depending on your requirements you may want to create a auth servlet that authenticates users to ldap server using for ex netscape's ldapjdk package or JDNI classes, and then keep users login in the session object. All you protected servlets/jsps should assert the session checking if user's info is in the session. Another option: to use JNDIRealm, but I can't advise on this b/c I never used it. - Boris Hi, I am new to the subject: How can I enforce ldap authentication for certain resources using tomcat - similar to the Directory toProtectResourcePath Options FollowSymLinks AllowOverride None AuthType Basic AuthName Authentication AuthLDAPURL ldap://ldapUrl require valid-user /Directory for apache in order to be able to get user information via e.g. getRemoteUser() etc. ?

RE: Why and How Tomcat before Apache?
Hi, All: Your help is highly appreciated for the following questions. 1. Does Tomcat have web-based administration functionality? We want to let the Tomcat administrator start/stop Tomcat through a Web-based interface. I have searched the mail archives, and found somebody starting working on it in April. Is it available now? If yes, where could I get it? That would make sense to do only if your run tomcat in a combination with a webserver (apache, etc) not in a standalone mode. You can create a CGI script that runs start/shutdown tomcat scripts. There is a security concern though: you should make sure only valid users can do this. - Boris

Re: request for suggestions on how to secure a web application....
I'm not sure whether it'll work for you but you can assert current session on each jsp page that you want to protect (assuming you store user login info in the session) and throw an exception in case the object is not found in the session, then the exception can be caught by an error jsp page. hth - Boris This posting is a request for suggestions on how best to secure a web application. First my setup: NT 4.0 Apache 1.3.12 Tomcat 3.2.1 (running behind Apache) servlets jsp pages static html pages jdk1.3 Web-app directory structure: webapps/my_context/ /jsp/jsp_pages /web-inf/classes/my_servlets /web-inf/classes/beans/my_java_beans My static html files reside under the apache document root. For servlet access I am using session cookies, as specified in the Java Servlet Spec, to authorize users. This works very well for my purposes. My concern is protecting sensitive jsp and static html pages. How do I stop an unauthorized user from accessing a jsp or html resource directly? ie: a back-door attack. For example, I am protecting my site with a login page, but if a user simply sidesteps the login and types http://my_domain/my_context/jsp/any_jsp_page into his browser, he will get access to any jsp page that resides in the specified context. I have experimented with some different approaches: 1. hide the jsp directory directly under the /web-inf directory and let Tomcat restrict access. So I would have: /web-inf/classes/servlets /web-inf/jsp/jsp_pages Then provide access to jsp pages only through a verification servlet, which can verify the user and then forward the request to the correct resource. However, this is causing problems when I utilize a RequestDispatcher(path).forward(req, res) or RequestDispatcher(path).include(req, res) instruction. The path needs to start with a / and be relative to the context root, per the Java Servlet API docs, which makes it impossible(?) to provide a correct path, since my verification servlet, and hence the execution thread, is in /web-inf/classes. When I issue the forward or inlude, I need to provide a path that looks something like: /../jsp/jsp_page which is correctly making the JVM puke. 2. Utilize the apache rewrite module and have apache rewrite all requests for http://my_domain/my_context/jsp/*.jsp to my verification servlet. The verification servlet can then do its thing and forward valid requests to the appropriate request. A hornet's nest of complexity here! and my nose tells me this is the wrong path to take. 3. Thought a lot about utilizing the Tomcat API. ie: RequestInterceptor, Virtual Host, Valves etc. I found rudimentary information about what these constructs are, but very little on how to use them. So, I am kinda stumped :-( I guess the next step would be to explore Basic or Digest Authorization, but I was hoping there would be a simpler way, that uses the power of servlets I would greatly welcome any and all suggestions Thank you, and keep up the great work. The Tomcat effort rocks! Peter BTW, I anticipate that the Tomcat docs will improve greatly in the future, and I was greatly encouraged to see the effort being put into making a book, and the template forming around v4.0 I would like to suggest a section on real world examples, using and programming the Tomcat API and the xml config files, like server.xml. For an example of what I mean, the documentation for the Apache mod_rewrite, written by Ralf S. Engelschall, has a section on practical solutions. http://httpd.apache.org/docs/mod/mod_rewrite.html That's kinda what I mean.
Re: How to increase debug reporting?
in server.xml modify Logger elements. To specify log file use path attribute: Logger name=tc_log path=logs/tomcat.log erbosityLevel = DEBUG / this will redirect tomcat msgs to file $TOMCAT_HOME/logs/tomcat.log. Also in Context element you can specify different debug levels for your paticular webapp using debug=number. Somebody already posted the levels on the mailing list: Level 0 Errors and states that cause a significant change in program flow. = Anything that causes a Discon+Retry or a giveup message. Level 1 Important or inaccessible state information. = Connection start, Idle disconnection. Level 2 Rare things that cause a minor program flow adjustment. = No REST, No PASV, etc. Level 3 Errors and useful messages that are slightly too verbose or common for 0-2 or don't quite fit in the classifications. = Login banner Level 4 All remote responses or major results. (Trace results) = All 999 Xyzzy responses received. Level 5 All remote commands or major tasks. (Trace jobs) = All commands sent to server. Level 6 General information that will not be too verbose but is normally a little less important. (Trace state) Level 7 Similar to level 3 but verbose or not as useful. Level 8 Very verbose information that'll probably be useful sometime. Level 9 Anything and everything else, debugs that probably won't be useful ever again.(unclassified) hth - Boris I know there are 3 main logs that I can set verbositylevel=debug to squeeze more info from tomcat... What else can i do? I see debug=0 all over the XML configuration files but I don't know which ones i should change, or where the info would go, or even what values to use. On a related topic, I cannot redirect stdout and stderr to files... all the directions seem to have disapeared... can someone point me in the right direction?

Re: Reloading
Hi Hector, This question has been asked several times and it seems nobody wants to answer it. I did ask similar question too a couple months ago with the same result :-( I do not think I know the exact answer, but from my experience I see the following. 1. classes must be in WEB-INF/classes in order to be reloaded (Tomcat doc) 2. reloading is experimental feature and there is no guarantee that clases other than servlets will be reloaded. 3. one can see intermittent problems with class reloading in tomcat (I personally use 3.2.1) even if condition 1 is true. I am not sure how tomcat reloading is implemented but it seems that reloading problems happens if the class to be reloaded keeps a reference to an existing object. In our case it happens during some exceptions that are not properly handled by developers (for ex, due to sql errors db connection is not returned to a pool or not closed). Then the object is not destroyed during reloading. Making code clean like proper releasing resorses avoids relaoding problems in our case. Try to look at your code and make sure your servlets close all references properly especially when there are exceptions. hth * * Boris NiyazovPh: 212-854-4094 Fax: 212-854-1749 * * Systems Manager Email: [EMAIL PROTECTED] * * Columbia Law School URL: http://www.law.columbia.edu * * Hi servleters: I've making some tests trying to resolve when and how Tomcat does a servlet reloading.

Re: mysteriously dying connections (Oracle - tomcat)

(or returned back to the connection pool if one is used) the driver we use is the Oracle jdbc ThinDriver (jdbc driver type 4). after running the system for several days, dead connections (and as we just discovered, tons of open cursors) pile up. eventually the webserver(tomcat) will crash or just hang. in the process, access gets slower and slower, there may be delays of 3 minutes until the webserver (or, perhaps the database, in which case the webserver would be just waiting for the db..) gives a response. after a restart of the webserver or the database or both, the system runns very well again. we tried several connection pools. with these, there were no delays for getting a connection, but the pool threw timeoutExceptions (i.e. made it visible that there are hanging connections) and after a few hundred timeouts the VM crashed with a stack overflow. the connections seem to get killed/kill themselfes randomly no matter which function was called. we log the methods and statements that were called for the connections that die, but there is just no pattern in it. thats why we dont find the root of the problem.. is it the driver ? the database ? the tomcat ? environment: Web Server: Suse Linux 7.2 Apache Webserver /w Tomcat JSP Engine 3.2 /w SSL DB Server: Suse Linux 7.2 Oracle 8i 8.1.7 /w multi-threaded server (MTS) Backup Server: Oracle Shadow server things done: - linux update - apache update - tomcat update - jdbc thin driver update (everywhere the newest version) - tried several connection pools possible changes: - - use OCI drivers instead of thin driver - use J-serv with GNU_jsp instead of tomcat every help is welcome, we're frustrated to no ends. thanks very much in advance!! l.sägesser - Boris

Hello,
I've read on this list that Tomcat 3.2 supports
serializing sessions attributes. I wanted to try it,
but could not find more information on the subject
here. So I tried to do it according to the servlet 2.2
specification. As it is not working, I try to sum-up
here what I've done:
I have installed 2 Tomcat 3.2 on the same machine
(taking care that the 2nd Tomcat starts on port 8081),
and for each of them, I have built a very simple
session webapp :
- session/
- WEB-APP/
web.xml
- classes/
SessionServlet.class
The web.xml looks like:
?xml version=1.0 encoding=ISO-8859-1?
!DOCTYPE web-app
PUBLIC -//Sun Microsystems, Inc.//DTD Web
Application 2.2//EN
http://java.sun.com/j2ee/dtds/web-app_2_2.dtd;

servlet-namesession/servlet-name
servlet-classSessionServlet/servlet-class
/servlet
servlet-mapping
servlet-namesession/servlet-name
url-pattern/session/url-pattern
/servlet-mapping
/web-app
For the firt Tomcat, I compiled:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class SessionServlet extends HttpServlet {
public void doGet (HttpServletRequest req,
HttpServletResponse res)
throws ServletException, IOException
{
ServletOutputStream out = res.getOutputStream();
res.setContentType(text/plain);
out.println(SessionServlet 1 output);
ServletContext servletContext =
this.getServletContext();
servletContext.setAttribute(foo,abcdef..foo);
out.println(attribute foo, with value
abcde...foo, added in ServletContext);
HttpSession httpSession = req.getSession();
httpSession.setAttribute(bar,abcde...bar);
out.println(attribute bar, with value
abcde...bar, added in HttpSession);
out.close();
}
}
For the second Tomcat, I compiled:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class SessionServlet extends HttpServlet {
public void doGet (HttpServletRequest req,
HttpServletResponse res)
throws ServletException, IOException
{
ServletOutputStream out = res.getOutputStream();
res.setContentType(text/plain);
out.println(SessionServlet 2 Output);
ServletContext servletContext =
this.getServletContext();
String foo = (String)
servletContext.getAttribute(foo);
out.println(foo=+ foo + (get from
ServletContext));
HttpSession httpSession = req.getSession();
String bar = (String)
httpSession.getAttribute(bar);
out.println(bar=+ bar + (get from
HttpSession));
out.close();
}
}
Requesting respectively the first servlet, and the
second serlvet did not give the expected results:
http://127.0.0.1:8080/session/servlet/SessionServlet
SessionServlet 1 output
attribute foo, with value abcde...foo, added in
ServletContext
attribute bar, with value abcde...bar, added in
ServletContext
http://127.0.0.1:8081/session/servlet/SessionServlet
SessionServlet 2 Output
foo=null (get from ServletContext)
bar=null (get from HttpSession)
So did I made a mistake, did I forget something, or is
it simply not possible to do it ?
Thanks for any help !

If the login page does not come up (btw, what happens does it just take you direct to the protected resource?) the first place I would look is the tomcat config files. So basically I would double-check server.xml and the web-xml for your app. If you are sure they are correct and you still have a problem you might want to try posting the relevant sections to the list. If you do get JDBCRealm working with tomcat standalone then to integrate with apache you need to add JkMount /examples/jsp/security/login/j_security_check ajp13 (or ajp12 if using mod_jserv) to httpd.conf to tell apache to delegate the handling of this bit of magic to tomcat. andrew On Wed, 13 Jun 2001, you wrote: Mark, I appreciate your help. I have tried to adapt the examples and I believe I have everything in place. However, apache just wont bring the login form when I try to access a protected resource. Would you have any idea where to look at for this problem? You might want to check and see if you can get a JDBCRealm to work with tomcat standalone(i.e. accessing you site as http://localhost:8080/... directly). If this doesn't work get this working first and that's a good place to start from. Once you have JDBCRealm working correctly then you can deal with making sure it works when passed through apache. --- Michael Wentzel Software Developer Software As We Think - http://www.aswethink.com

Re: What is the value of auto-assigning beans?
1. setProperty in jsp does not have any effect if the value is empty string. 2. you use scope session So when set A it stores it in the session bean, next time when you set B with no A, B gets set in the bean and A remains the same (session scope). hth * * Boris NiyazovPh: 212-854-4094 Fax: 212-854-1749 * * Systems Manager Email: [EMAIL PROTECTED] * * Columbia Law School URL: http://www.law.columbia.edu * * This question may be asked out of ignorance, but it seems to me that using the tag: jsp:useBean id=MyBean scope=session class=Test.MyBean / jsp:setProperty name=MyBean property=* / to assign values from form fields to the bean is of limited use. Let's assume that there are 2 text fields, A and B on Jsp1.jsp, with B being required. I have some code that checks to make sure B is populated, if it's not, the browser returns to Jsp1.jsp. The problem I run into is that I can populate A with a value, submit the form, get returned to Jsp1.jsp, delete A and populate B, submit the form, and continue. I how have values for both A and B, even though A was blank. I suspect that I'm not the first person to ask this question, is there an obvious solution that I missed, if not, what do other people do to get around this problem; do all of the assignements by hand?

Re: ClassCastException when passing a list of Beans to JSP page
Does this happen when you change you beans? If you have jsps that use the beans
with session scope then modifying the bean can cause this, especally if session
object remains in the memory... Restarting your browser should also help.

Content-Transfer-Encoding: 7bit
X-Spam-Rating: h31.sny.collab.net 1.6.2 0/1000/N
Hello All,
I am hoping someone can solve this mystery for me since I'm stumped.
I have a servlet which populates a vector with beans. It then puts the
vector into the request object and forwards to a JSP page.
The JSP page pulls the vector out of the request and proceeds to call
methods on each bean in the list.
Sometimes the whole thing quits working and complains with a
Internal Servlet Error:
javax.servlet.ServletException: sde.LayerBean
...
Root cause:
java.lang.ClassCastException: sde.LayerBean
...
Restarting tomcat solves the problem, but I'd like to understand what's
going on. I'm assuming that it's the JSP page throwing the exception
(the errorPage directive engages).
Can someone enlighten me? I'm using Tomcat 3.2.1 (standalone) on Linux
JDK1.3. The JSP page is listed below.
Thanks!

I have a web site that is currently using jserv, but we are upgrading the server and I want to move the site over to tomcat. However, tomcat's default behaviour is to stick the work servlet in the URL between the context name and the servlet being accessed. This breaks all my HREFs. Instead of rewritting all the HREFs on 50 pages, I want tomcat to not use a the servlet prefix. I have tracked this default behaviour down to a couple of lines in the server.xml file. !-- Non-standard invoker, for backward compat. ( /servlet/* ) You can modify the prefix that is matched by adjusting the prefix parameter below. Be sure your modified pattern starts and ends with a slash. NOTE: This prefix applies to *all* web applications that are running in this instance of Tomcat. -- RequestInterceptor className=org.apache.tomcat.request.InvokerInterceptor debug=0 prefix=/servlet/ / The problem is that when i remove this RequestInterceptor or make prefix= or prefix=/ - i don't get access to the servlets and end up with a 404 error.

RE: Tomcat SSL
I see a little misunderstanding here. Apache with mod_ssl or apache-ssl module uses ssl connection with http clients. The communication between apache and the servlet container is done via ajpXX protocol that can be secure or not. As I understand ajp12 (that mod_jserv uses) does not support SSL while ajp13 (that mod_jk uses) does. So, if apache and the servlet container are residing on the same box, one can use apache-ssl with mod_jserv or tomcat+ajp12 and be secure (that what we do here). When using communication between apache and the servlet container is done via net, one should probably use ajp13, meaning tomcat+mod_jk. This is my 2 cents * * Boris NiyazovPh: 212-854-4094 Fax: 212-854-1749 * * Systems Manager Email: [EMAIL PROTECTED] * * Columbia Law School URL: http://www.law.columbia.edu * * Mailing-List: contact [EMAIL PROTECTED]; run by ezmlm list-help: mailto:[EMAIL PROTECTED] list-unsubscribe: mailto:[EMAIL PROTECTED] list-post: mailto:[EMAIL PROTECTED] Delivered-To: mailing list [EMAIL PROTECTED] Date: Tue, 24 Apr 2001 16:32:03 -0500 (CDT) From: Milt Epstein [EMAIL PROTECTED] X-X-Sender: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: RE: Tomcat SSL MIME-Version: 1.0 X-Spam-Rating: h31.sny.collab.net 1.6.2 0/1000/N On Tue, 24 Apr 2001, GOMEZ Henri wrote: -- mod_jserv won't work if you want to use SSL Why not? SSL stuff in apache is done in apache, and jserv is only a connector. The SSL in apache works the same way in mod_ssl, and mod_jserv. The only difference is that in Servlet Spec 2.0 (JSDK2.0 which jserv is) has no notion of SSL (to my knowledge), and you cannot really do anything with SSL within servlets, unless you write everything yourself. You still get the CGI environment variables, so you probably can find out that request was handled as HTTPS, but apache takes care of it for you, and you cannot make much use of it within a servlet. mod_jserv didn't support SSL neither ajp12. You must use mod_jk with ajp13 to get SSL info forwarded from Apache to Tomcat. [ ... ] Can you clarify what you mean bu this? Because I'm using Apache with mod_ssl, and Tomcat with mod_jserv, and things are working just fine. Perhaps there's some functionality I don't have, but I guess I haven't needed it yet.

Re: [tc3.3] configuring logging
Read JSP spec. You should use application.log(...) in your JSP pages. HTH * * Boris NiyazovPh: 212-854-4094 Fax: 212-854-1749 * * Systems Manager Email: [EMAIL PROTECTED] * * Columbia Law School URL: http://www.law.columbia.edu * * Hi, I have a few questions about Tomcat3.3 server.xml configuration, and logging in particular. First, is there *any* documentation of the various server.xml tags? A DTD perhaps? One of the nicest things about tc4.0 is how clean and obvious server.xml has become. By contrast, 3.3 is a mess, littered with references to Interceptors, and odd tags like: SessionExpirer checkInterval=60 /. Second, is there any magic tag that will let me log stderr and stdout to a file? Third (and this may be a bug), what happens to log() messages within JSPs? If I have a JSP: % log(This is logged with log()); % and run it, the output doesn't appear in logs/*, or on stdout/stderr.. is it being lost? thanks, --Jeff - Boris

Re: Reloading Servlets
Do not reboot. Just shutdown and restart tomcat. In 3.2.1 release notes it's said that reloading classes is experimental feature and is not garanteed to work 100%. I have similar problems with reloading my beans. Nobody answered my question so far, so I tend to beleive the doc is right: reloading does not work all the time. * * Boris NiyazovPh: 212-854-4094 Fax: 212-854-1749 * * Systems Manager Email: [EMAIL PROTECTED] * * Columbia Law School URL: http://www.law.columbia.edu * * Hi, I've been writing servlets, testing them as I go with my Tomcat-Apache Server and Netscape... I've run into the problem that sometimes, not all the time, when I refresh a servlet to see changes, it's not changed? I closed Netscape, deleted my web cache, and closed Kawa. But still the next time I run it, it's still there unchanged... Usually I have to re-boot... is Tomcat or Apache Caching my servlets? Any Ideas on how to fix this? Thanks in Advance, Colin Morris.

Beans do not get reloaded
Hi there, I have Tomcat 3.2.1, Java SDK 1.3.0 installed on Solaris 7 machine. I am having intermittent problems with beans reloading. It seems that sometimes the beans are not reloaded after the compilation, and the jsp page is referecing the old version of the bean. I have to restart tomcat in order for it to reload the beans. Again I can't find a pattern when this happens but it does happen. I'm not sure whether it's a memory leak or I am missing something. Any help/hint will be greatly appreciated.
