getAttribute(null)?
I have the following code that worked in Tomcat 5.0, but doesn't work in
Tomcat 5.5.26:
String formName = mapping.getAttribute(); // mapping is a variable of
type ActionMapping. In this scenario, formName is null.
if (null != session.getAttribute(formName)) {
session.removeAttribute(formName);
}
formName is null. In Tomcat 5.0.x, no exception was thrown and

simply returned NULL). In Tomcat 5.5.26, a ServletException is thrown
(with a NullPointerException).

get rid of ViewExpiredException
Hi, I keep getting a ViewExpiredException when testing on my localhost. I am running Tomcat 6.0.16 inside Eclipse 3.3.2 with Myfaces 1.2.3 (JSF 1.2) and Spring 2.5.4. All I want to do is get rid of this exception. I have restarted Tomcat, cleared my browser cache, redeployed the webapp, cleaned the Tomcat working directory, and rebooted my machine. No combination of these seems to work. I understand that before I get too far, I will need to implement some logic for handling this exception correctly, but at the moment I just want to be able to test everything else. Does anyone know how to quickly and easily stop this exception from being thrown every time I click anything in my webapp?

RE: Tomcat 5.0.28 memory usage - garbage collection
thanks. The reason we have to stick to using this version is that it is recommended by another application that tomcat is acting as a client to.

RE: getAttribute(null)?
It's not the why is formName null? that I'm worried about. In this
case, it's supposed to be null.
What I want to know is this: Is a NullPointerException supposed to be
thrown if the argument name in session.getAttribute(name) is NULL? If
such an exception IS supposed to be thrown, was this a change put into
Tomcat 5.5.x that wasn't in 5.0.x?

jk load balancing based upon ip address rather than session id
Hello, I'm using jk 1.2.25 with tomcat 5.5.25 and apache 2.0 on one debian box - 2.4.27-2-386 i686 GNU/Linux I've set up 3 tomcat instances that receive requests from the jk load balancer worker I've implemented in the web application, a simple cross domain single sign on (SSO) mechanism. This mechanism ties the different session ids in any single container together, regardless if they've originated from different domains, for example: sub1.mydomain.com sub2.yourdomain.com sub3.hisdomain.co.uk Hence when a user logs on this is then reflected in all the different sessions that they might be in a particular container for that user, from the serviced domains that they've visited. This is fine when there is just one container. But when there are several all servicing requests in a load balanced context, it doesn't work, because the session ids from different domains may be directed to different tomcat instances / containers, which then breaks the assumption that the SSO mechanism relies upon (that all sessions being held in a single container). The tomcat instances aren't in a distributed cluster and I'd like to keep it that way. My initial idea is to balance the traffic based upon the ip address rather than the session id, thus I can be assured that all requests from a particular ip address will hit the same container, and hence the single sign on mechanism will work. I realise that this would give me a much less granular balancing profile. I'd much prefer to do this through the jk load balancer although as an alternative I could do it through the balancer web app that comes with tomcat and implement a Rule in java myself. I'm open to other ideas that get the job done. I've read the following: http://tomcat.apache.org/connectors-doc/generic_howto/loadbalancers.html http://tomcat.apache.org/connectors-doc/reference/workers.html http://tomcat.apache.org/tomcat-5.5-doc/balancer-howto.html http://venus.rainbow-it.net/manual/en/mod/mod_proxy.html I've searched the forums as well, I had a cheeky look at the source too for shits and giggles, but still no joy. native/common/jk_lb_worker.c seems like the get_most_suitable_worker function is very much driven from the session id - I'm no a C programmer :-( My question is has anyone already done this? Is there a better way of doing it that I'm missing, or should I basically just do it through the balancer web in tomcat app and forego the jk load balancer, or bite the bullet and make the tomcat containers a cluster. Any suggestions / help would be very much appreciated Cheers Simon - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Changes to are tomcat project may affect the way it communicates with a database, and therefore we'd like to make sure the deployment takes place swiftly.

Servlet navigation
I am doing a project for a class of HS teachers in July, to teach them
the wonders of Java and NetBeans. I designed a set of servlets to let
them manage student grades. I am having them design the basic HTML in
NVU, and put it into the try blocks of the NB-generated processRequest
servlets, and then put it into out.println(...); blocks. I am using
Tomct.
I would use JSF myself, but I have no time to get into that, so I am
using forms and submit buttons to do the navigation.
So the first test is to see if the navigation works with the static HTML
servlet pages. When that works, I will put in the database queries. But
the navigation is not working for me. I changed the Project (classdata)
Run property in NB to point to login.
Here is the processRequest login code:
response.setContentType(text/html;charset=UTF-8);
PrintWriter out = response.getWriter();
try {

I tried tail -f [file log] | logger -p local#.info but this resulted in each wrapped line occurring as a new syslog message. The tomcat and coherence events are rather long and can include stack traces. I want to keep the entirety of their events as a single message event in syslog.

mapping tomcat to ip address behind router

I'm beginning to see the problem. That wasn't entirely clear from your original post. Since you want to use SSO, I'm assuming that you are running all three (or more) applications in the same instance of Tomcat, even though there are multiple instances of Tomcat at work (on separate servers, presumably). The first request to each of these domain names does not include a cookie because the domains do not match. Each initial request to the distinct domains causes a fresh random choice amongst the servers, so you are not likely to get lucky and have all your initial requests randomly end up at the same server, and therefore SSO fails. :( | Let me know if I'm misunderstanding some fundermental way in which the | jk load balancer works, or if I'm not explaing myself well, No, you were right... I just wasn't understanding your initial question. So, really, it's not that you want to load balance based upon IP address... you really want to predictably choose a member of the server farm based upon some knowledge of the client such that, regardless of the domain name used, the initial request (and therefore all the rest) go to a particular member. You may be able to do this, but you'll certainly have to hack mod_jk in order to do it. I believe there is a method in mod_jk that chooses the jvmRoute for the first (JSESSIONID-less) request. If you were to modify that algorithm, you could achieve your goal, here. I'm a little worried that you might implement a fragile algorithm, though, and end up with an unbalanced load balancer. Do you have options other than using SSO? Come to think of it... how does SSO work when you switch domains with even a single server -- that is, without load balancing in the mix? I would expect that, since you are switching domains, your browser would not send a JSESSIONID cookie to the server, and thus you would not be recognized as having an existing session. ??! - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkhRqswACgkQ9CaO5/Lv0PDukQCeMKv8qpvuvKsag1AMLWqsaNSV GA4An19MrUrE/FPRTGMpWvNSLgF5Zs3K =n6yV -END PGP SIGNATURE- - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Well, whatever the solution is, there's no need to specify the address in server.xml unless you want to specify a single network interface for your server. For the time being, you should leave that out. Have you tried to hit your server from outside your network, or only from inside?

When there is a direct internet connection and no router, and the address property is added and port number is changed in server.xml as below in example 1, tomcat serves requests fine for http://99.153.32.456. When I set it up to run behind a router as show in example 2, with the router forwarding requests to 192.168.0.54 which is the computer behind the router with tomcat, it does not work for the url http://99.153.32.456. What is the correct way to set it tomcat behind a router? thanks in advance for your assistance Example 1 - no router - works Connector port=80 protocol=HTTP/1.1 connectionTimeout=2 address=99.153.32.456 redirectPort=8443 / !-- A Connector using the shared thread pool-- !-- Connector executor=tomcatThreadPool port=80 protocol=HTTP/1.1 address=99.153.32.456 connectionTimeout=2 redirectPort=8443 / -- Example 2 - behind router - does not work Connector port=80 protocol=HTTP/1.1 connectionTimeout=2 address=192.168.0.54 redirectPort=8443 / !-- A Connector using the shared thread pool-- !-- Connector executor=tomcatThreadPool port=80 protocol=HTTP/1.1 address=192.168.0.54 connectionTimeout=2 redirectPort=8443 / -- illusion, you have now probably screwed up the TC config... Reload the the standard TC config, and just change the 8080, to 80, dont touch other stuff for now. Then google, I think you have one of those ADSL Nat Router things Heres an article with someone else struggling along http://sanzon.wordpress.com/2008/04/04/setting-up-web-server-behind-router-wrt54g2/ Whats probably screwing you up is even though you have it forwarding, the IP's internally are being dynamicly assigned, you have to give the server a fixed IP, typically this is not the ISP IP, its the machine IP, and then you need to check the machine and make sure its using your router as the gateway. Its not really a TC thing, best thing is to look at the router name and google for it and web server. These little box's now a days have some amazing functionality, so you need to find the manual for the thing. You need to check the Dynamip DNS is not on, DHCP is not assinged to the server, the DNS discovery is set or on auto, the network masks are right etc. If your SP supplied the router, they should know how to set the thing up, dont mention tomcat, its got nothing to do with it, just tell em its a web server on a machine if that works, TC will work. And then learn to do things like ping a machine etc. Have fun --- HARBOR : http://www.kewlstuff.co.za/index.htm The most powerful application server on earth. The only real POJO Application Server.

URL is null and HTTP 404 error when using FROM authentication
Hi I have this wierd problem i am trying to sovle for a week now, and i already have gray hair from this mess. My setup is Apache 2.0, Tomcat 6.0, MySQL 5.0. I am requesting a protected page in my application: http://127.0.0.1/myapp/home.jsp and it takes me to the login page: http://127.0.0.1/myapp/index.jsp I type in my username + password and hit login, and brought back to the login page. I tried filtering the problem by using BASIC authentication + using tomcat-users.xml which worked out fine. FORM + tomcat-users.xml did not work out. I am totally lost and begining to think that this is some kind of a bug in j_security_check. I saw somebody had a very very similar problem but I did not catche the solution: http://mail-archives.apache.org/mod_mbox/tomcat-users/200705.mbox/[EMAIL PROTECTED] In addition I enabled combined logging and this is what I see: 127.0.0.1 - - [13/Jun/2008:00:32:45 -0400] GET /hamula/home.jsp HTTP/1.1 200 2250 null Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; InfoPath.1) 127.0.0.1 - - [13/Jun/2008:00:32:45 -0400] GET /hamula/images/kubrickbgcolor.jpg HTTP/1.1 404 1051 http://127.0.0.1:8080/hamula/home.jsp; Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; InfoPath.1) 127.0.0.1 - - [13/Jun/2008:00:32:49 -0400] POST /hamula/j_security_check HTTP/1.1 200 2250 http://127.0.0.1:8080/hamula/home.jsp; Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; InfoPath.1) 127.0.0.1 - - [13/Jun/2008:00:32:49 -0400] GET /hamula/images/kubrickbgcolor.jpg HTTP/1.1 404 1051 http://127.0.0.1:8080/hamula/j_security_check; Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; InfoPath.1) you can see that in the first entry i get null and then 404.

RE: URL is null and HTTP 404 error when using FROM authentication
From: exkor [mailto:[EMAIL PROTECTED] Subject: URL is null and HTTP 404 error when using FROM authentication You have some weirdness in your web.xml and context.xml that should be straightened out before attempting any further analysis. servlet servlet-name/servlet-name display-name/display-name servlet-class/servlet-class load-on-startup0/load-on-startup /servlet I have no idea what should be done with an empty servlet declaration, and it's possible Tomcat doesn't either; get rid of it. auth-constraint role-nameadmin/role-name role-namemanager/role-name /auth-constraint ... security-role role-nameadmin/role-name /security-role Either you have an extra role listed in auth-constraint, or you're missing one under security-role; get them in synch. My context.xml: Where is your context.xml file? It should be in your webapp's META-INF directory. If you've changed the global one in Tomcat's conf directory, put it back the way it was and put your Context element in the proper location. Context path=/hamula reloadable=true crossContext=true debug=99 The path attribute is not allowed in a Context element in context.xml; remove it. Logger className=org.apache.catalina.logger.FileLogger prefix=localhost_hamula_log. suffix=.txt timestamp=true/ There is no Logger element in Tomcat 6; remove it. Resource name=jdbc/hamula auth=Container type=javax.sql.DataSource driverClassName=com.mysql.jdbc.Driver url=jdbc:mysql://localhost:3306/hamula?autoReconnect=true/ username=root password=skywalker digest=MD5 logAbandoned=true removeAbandoned=true removeAbandonedTimeout=10 maxActive=20 maxIdle=10 maxWait=-1/ The above is obviously broken, since you have terminated the Resource element twice. Regardless, it seems odd for the Realm and the application Resource to be using the exact same data base; is that what you really want? Realm className=org.apache.catalina.realm.JDBCRealm Change the Realm back to the MemoryRealm for testing with FORM login; once you get that working, then move on to the JDBCRealm. One step at a time. You say you have httpd 2.0 in the mix; don't use it for testing, go straight to Tomcat's http port. Only after that works should you introduce any further complications. All of the above may not to fix your problem, but it will remove some confusion from your situation. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
