RE: Tomcat 6.0 always uses default host in multi-host config
-Original Message- From: Caldarale, Charles R [mailto:chuck.caldar...@unisys.com] Sent: Tuesday, May 25, 2010 4:47 PM To: Tomcat Users List Subject: RE: Tomcat 6.0 always uses default host in multi-host config From: Jeffrey Janner [mailto:jeffrey.jan...@polydyne.com] Subject: RE: Tomcat 6.0 always uses default host in multi-host config OK, to answer my own question on this, useIPVHosts is essentially a way to save some configuration writing at the expense of doing a reverse-DNS lookup on every access, correct? No. Setting useIPVHosts to true says to use the local IP address rather than the HTTP host header value for determining which Host to give the request to. Yes, but how does it determine the host to route to? That was the initial question. When you have a config like the OP, where each host is defined by name, not IP, in the server.xml, there is obviously some resolution of IP to name that has to take place. Now, whether it does that at each connection, or at startup cached, I don't know. I'm sure a search of source would provide that answer. I was only making an assumption about the process, but it still seems to me to be a little extra work involved for each connection to route it to the correct host. You can do it my way below, and have everything clearly spelled out It's only clearly spelled out to you, since you implemented. Looks like a lot more work and overhead to me, and certainly no simpler. or you can use this config trick and let TC manage it for you. It's clearly not a trick. Obviously, I meant clearer in terms of being able to understand what's going on without detailed understanding of the Tomcat source. It is more work to setup and not a simple implementation, but it is specific in the server.xml how traffic will route. There is nothing that Tomcat has to rely on outside the server.xml to properly route the traffic. Anything that magically does something is a trick, even if it's a specifically coded trick. The documentation I've seen essentially says, set this to true and tomcat will figure it out. I used trick in this manner, because I haven't found any specific documentation about how this feature is expected to function, i.e. how to set it up properly. Got a reference? Obviously, a real config trick is one where a certain combination of parameters produces beneficial effects but not ones specifically planned for (MS-based stuff is full of those). The term was misapplied in this case. But in a config setting useIPVHost=true will only route it to the correct host if the IP resolves to the host name or alias Which is exactly what the useIPVHosts setting is documented to do. Where? This is the only official documentation I have found on the feature: Set this attribute to true to cause Tomcat to use the IP address that the request was received on to determine the Host to send the request to. The default value is false. (http://tomcat.apache.org/tomcat-5.5-doc/config/http.html) That was my original question. As you can see, there is nothing about how it determines the host-IP mapping. In my researching the feature, I found 3 to 4 posts about folks having problems with this feature similar to the OP's over the past few years. Almost all were resolved with either an alias entry or setting an entry in the hosts file. I'm guessing a lot of folks don't set up reverse-DNS, and thus the problem. Aside from probably only needing to configure one port 80 connector, and probably allocating fewer resources as a result, is there any other advantage to the parameter? That seems to be a significant advantage to me. - Chuck I'm not saying it isn't an advantage, but given the drawback of having traffic route inappropriately if your name resolution is not perfect, is it that great? Are there other significant run-time advantages to this feature, or disadvantages or drawbacks to my setup? I'm not really advocating my set up as the way, as I can see this as a viable option, and one I might want to switch to if I understood it better. I have seen my config as a suggestion from others on this list in the last few weeks. OK, all the above aside, is my understanding of the feature essentially correct? To reitterate: 1) Set useIPVHosts to true in all Connectors. 2) When a connection is made Tomcat will look for a configured Host with that IP address as name or alias, and execute in that Host. 3) Otherwise it will make a call to the system resolver, passing the IP address to lookup and expecting a hostname in return. 4) Check returned hostname against server.xml Hosts and execute there if found. 5) If returned hostname is null or not found in server.xml, then execute in Engine's defaulthost. Or really, should we do what we'd do in Apache and set up the Host elements with name=ip address instead of a text-based name, and not really worry about the text-based name at all - eliminating the need for any

RE: Tomcat 6.0 always uses default host in multi-host config
From: Jeffrey Janner [mailto:jeffrey.jan...@polydyne.com] Subject: RE: Tomcat 6.0 always uses default host in multi-host config When you have a config like the OP, where each host is defined by name, not IP, in the server.xml, there is obviously some resolution of IP to name that has to take place. No, there isn't. The HTTP host header is already a name, so it's a simple string match. The only additional work is when useIPVHosts is true - the IP address has to be retrieved from the TCP/IP stack and converted to a string first. There is nothing that Tomcat has to rely on outside the server.xml to properly route the traffic. True regardless of the configuration. Anything that magically does something is a trick, even if it's a specifically coded trick. I still don't see why you think anything magic is going on; it all seems very straightforward to me. As you can see, there is nothing about how it determines the host-IP mapping. Because there isn't any. I'm not saying it isn't an advantage, but given the drawback of having traffic route inappropriately if your name resolution is not perfect, is it that great? Again, there's *no name resolution* going on - anywhere. HTTP requests come in with a host header, and that's what is normally used to determine which Host to give the message to. When you set useIPVHosts to true, you defeat this mechanism, as documented. 1) Set useIPVHosts to true in all Connectors. I have yet to see a valid reason to do that. The simplest, least overhead configuration is a single Connector for each port, and let the HTTP host header do the routing. You can set up the defaultHost to be one that simply returns an error if the client fails to send in a valid HTTP host header. You can also set aliases for expected synonyms of the Host name. 3) Otherwise it will make a call to the system resolver, passing the IP address to lookup and expecting a hostname in return. Nope, doesn't happen. Or really, should we do what we'd do in Apache and set up the Host elements with name=ip address instead of a text-based name, and not really worry about the text-based name at all - eliminating the need for any alias entries. No, because that eliminates the very common usage case of having multiple domains point to the same IP address; you want to be able to differentiate based on the URI of the request, not the IP address it happens to arrive on. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Andre, before you ask, I am still waiting on a test Windows 2003 server to be setup where I can test this on a server rather than my XP box as you suggested to me previously, but I'm stuck testing on my Windows XP box until then. 2.

I am testing my web app within Eclipse using Tomcat 6.0 (meaning my web app is a dynamic web project within Eclipse and has been added to the Tomcat server in Eclipse). 4. My URL is: http://localhost/SCMIS/index.jsp 5.

I have the feeling that your problem is not really related to authentication (or the lack of it). It is that there is some confusion as to the proper setup of IIS and Tomcat together, and how IIS handles virtual websites. Maybe we should restart from the beginning, like here : When you look at the ...\Tomcat 6.0\webapps directory, what are the sub-directories located just below it ?

Re: Why does errorPage work but WEB-INF/web.xml error-page does not?
Dave - looks like I just posted something for you to try in your JavaRanch forum thread... Basically, it looks like having a committed response (you've said that your original JSP was partially rendered) can interfere with the error page mechanism. For testing purposes, try increasing the page buffer to see what happens. You may want to consider changing your approach to incorporate filters/servlets for some of your processing...

RE: Question on workers.properties file
Ranier - thanks for the reply. 1.

Andre, before you ask, I am still waiting on a test Windows 2003 server to be setup where I can test this on a server rather than my XP box as you suggested to me previously, but I'm stuck testing on my Windows XP box until then. 2. Currently I am testing to see if using the Tomcat connector will work on my local Windows XP box. 3. I am testing my web app within Eclipse using Tomcat 6.0 (meaning my web app is a dynamic web project within Eclipse and has been added to the Tomcat server in Eclipse). 4. My URL is: http://localhost/SCMIS/index.jsp 5. The directory structure on my local box where my web app is located is: C:\Snaps\savoym_remote_scmis_phase5_dev\scmis_phase5_vob and the directories directly under this directory is: Build Common Libraries Lookup Lost+found Maintenance PurchaseOrder Requisition SCMIS (this is the where the JSP's are located and this is the directory that is defined in my SCMIS IIS virtual web site) Security 6. In IIS 5.1, on my Windows XP box, the setup is as follows: a. Default website has a directory security setting of (Anonymous access - checked) b. jakara virtual website has a directory security setting of (Anonymous access - checked) c. SCMIS virtual website, within the jakarta virtual website, has a directory security setting of (Windows Authentication - checked) Does it work, if you switch all of those three to Anonymous access unchecked and Windows Authentication checked? What is the SCMIS virtual website in IIS for? Are you trying to serve static content directly form IIS? If no, I don't see a reason why you would want to have that virtual website. Are you forwarding /SCMIS/* to Tomcat, or only JSPs? As I wrote in a previous post, it didn't work for me when i only switched the jakarta virtual website to Windows auth. It only started to work, when I changed the default website too.

Stopping a Timer in contextDestroyed() to avoid memory leaks results in a NullPointerException
Hi,
Thanks for reading this.
I am developing a webapp and do not understand the following:
In my app, I create a Timer when the servlet starts.
When tomcat stops, I try to stop the timer in order to avoid memory leaks.
My question is: why do I get a NullPointerException while trying to access
mytimer in contextDestroyed().
The simplified code:
public class myclass extends HttpServlet implements ServletContextListener {
java.util.Timer mytimer;
int testint;
public void init() throws ServletException {
mytimer = new Timer(__test__);
TimerTask taskPerformer = new TimerTask() { public void run() {
whatever_function(); } };
mytimer.scheduleAtFixedRate(taskPerformer, 10, 10, 864000);
testint = 12;
}
public void contextDestroyed(ServletContextEvent event) {
System.out.println(Inside contextDestroyed, testint=+testint);
try {
mytimer.cancel();
}
catch (Exception e) {
System.out.println(An error occurred inside
contextDestroyed(): +e);
}
}
public void contextInitialized(ServletContextEvent event) {
// Nothing here
}
public void destroy() {
// Nothing here
}
}
The Output:
May 26, 2010 8:06:30 PM org.apache.catalina.core.StandardService stop
INFO: Stopping service Catalina
Inside contextDestroyed(), testing=12
An error occurred inside contextDestroyed(): java.lang.NullPointerException

clearReferencesThreads
SEVERE: A web application appears to have started a thread named [__test__] but
has failed to stop it. This is very likely to create a memory leak.
What disturbs me, is that my other variable testint is accessible within
contextDestroyed, but not mytimer.
If I save my timer in init() like this:
ServletContext sc = getServletContext();
sc.setAttribute(mytimer, mytimer)
and if I modify contextDestroyed() so that it accesses my timer through
ServletContext
ServletContext context = event.getServletContext();
Timer mytimer2 = (Timer)context.getAttribute(mytimer);
then I have no problem stopping it, making the tomcat warning disappear.
I'd like to understand why it is so.
Thank you very much in advance

Re: Stopping a Timer in contextDestroyed() to avoid memory leaks results in a NullPointerException
Hi,
thank you for your reply.
First I'd like to say that I do implement ServletContextListener at all
beacause destroy() fires after the tomcat warnings.
That being said, on this website:
http://stackoverflow.com/questions/2255884/jython-and-implementing-httpservlet-contextinitialized
is written that You can optionally also let your servlet both extend
HttpServlet and implement ServletContextListener
It is also said that it is not always considered a good practice.
Why is that so ?
Would that be an explanation why in my case I can access some variables but
others not ?
Thank you for your help.

Re: Stopping a Timer in contextDestroyed() to avoid memory leaks results in a NullPointerException
Hi,
You could also eliminate the mix match and add a finally, with the
following servlet code for example:
public void init() throws ServletException {
boolean initOk = false;
mytimer = new Timer(__test__);
try {
TimerTask taskPerformer = new TimerTask() { public void
run() { whatever_function(); } };
mytimer.scheduleAtFixedRate(taskPerformer, 10, 10,
864000);
testint = 12;
initOk = true; // as last
} finally {
if (!initOk) {
mytimer.cancel();
}
}
}
public void destroy() {
System.out.println(Inside destroy, testint=+testint);
try {
mytimer.cancel();
} catch (Exception e) {
System.out.println(An error occurred inside
contextDestroyed(): +e);
}
}
I added a finally / cancel in the init method, because as Kostantin
Kolinko said yesterday, if there is an exception in the init method
after a timer creation, then the destroy method is not called and the
timer is never canceled even if your webapp is unusable (and Tomcat
6.0.26 will warn about that timer).
I supposed here that your init method is not so simplified.

You can optionally also let your servlet both extend
HttpServlet and implement ServletContextListener
It is also said that it is not always considered a
good practice.
Why is that so ?
Because, as you have inadvertently discovered, separate instances of the class
are created for each purpose. If you make the mytimer field static (along with
any others you want to use in both instances) you won't have a problem.

No, it's because the same class was used as both a servlet and a listener, and the field holding the timer reference was not static. Tomcat instantiates separate objects for the servlet and listener; the timer reference was set in the servlet instance, but still void in the listener instance.

Re: Stopping a Timer in contextDestroyed() to avoid memory leaks results in a NullPointerException
Hi Chris,
The initial submitter had a HttpServlet implementing
ServletContextListener with a non static timer, and in fact there were 2
instances of the class: the contextDestroyed method of the
servletContextListener instance can't cancel the timer of the
httpServlet instance (NullPointerException as he said) then Tomcat
6.0.26 stopped the leak.
As Pid said there is a mix and match. To fix it, the init and destroy
methods of the HttpServlet can create and cancel the timer cleanly (no
more NullPointerException and no more leak).
Then I just wanted to suggest a finally and a cancel in the init method
to be cleaner (because if there is an OutOfMemoryError or something like
that in scheduleAtFixedRate, then the leak appears again except that
Tomcat 6.0.26 stops it. Thanks Konstantin).

RE: Tomcat 6.0 always uses default host in multi-host config
-Original Message- From: Caldarale, Charles R [mailto:chuck.caldar...@unisys.com] Sent: Wednesday, May 26, 2010 10:23 AM To: Tomcat Users List Subject: RE: Tomcat 6.0 always uses default host in multi-host config From: Jeffrey Janner [mailto:jeffrey.jan...@polydyne.com] Subject: RE: Tomcat 6.0 always uses default host in multi-host config When you have a config like the OP, where each host is defined by name, not IP, in the server.xml, there is obviously some resolution of IP to name that has to take place. No, there isn't. The HTTP host header is already a name, so it's a simple string match. The only additional work is when useIPVHosts is true - the IP address has to be retrieved from the TCP/IP stack and converted to a string first. That was what I was saying. Please read in context of the thread. The topic is about what happens when useIPVHosts=true. So it seems we are in agreement here. Of course, with the it set to true, isn't the host header string ignored? Isn't that the point? If the HHS is not ignored, why? There is nothing that Tomcat has to rely on outside the server.xml to properly route the traffic. True regardless of the configuration. Anything that magically does something is a trick, even if it's a specifically coded trick. I still don't see why you think anything magic is going on; it all seems very straightforward to me. As you can see, there is nothing about how it determines the host-IP mapping. Because there isn't any. I'm not saying it isn't an advantage, but given the drawback of having traffic route inappropriately if your name resolution is not perfect, is it that great? Again, there's *no name resolution* going on - anywhere. HTTP requests come in with a host header, and that's what is normally used to determine which Host to give the message to. When you set useIPVHosts to true, you defeat this mechanism, as documented. I'm not debating that! The entire discussion is about what happens with useIPVHosts set to true! Please comment on the topic or get off the thread! 1) Set useIPVHosts to true in all Connectors. I have yet to see a valid reason to do that. The simplest, least overhead configuration is a single Connector for each port, and let the HTTP host header do the routing. You can set up the defaultHost to be one that simply returns an error if the client fails to send in a valid HTTP host header. You can also set aliases for expected synonyms of the Host name. Please go back to the OP. He had a valid reason: needing multiple/different SSL certs based on IP, and wanting to route to a specific host based on that link. My config was an alternate for achieving his desired functionality without the use of the useIPVHosts parameter. But I can see how using it might mean less typing when setting up the server.xml. I'm just trying to get some clarification on the expected use of the parameter. (I like the comment about overhead. Now you're agreeing with me on something you dinged me for two posts before.) 3) Otherwise it will make a call to the system resolver, passing the IP address to lookup and expecting a hostname in return. Nope, doesn't happen. Or really, should we do what we'd do in Apache and set up the Host elements with name=ip address instead of a text-based name, and not really worry about the text-based name at all - eliminating the need for any alias entries. No, because that eliminates the very common usage case of having multiple domains point to the same IP address; you want to be able to differentiate based on the URI of the request, not the IP address it happens to arrive on. - Chuck OK, now I'm confused. ;-) It seems that on the one hand, you are saying that with useIPVHosts=true, the IP address determines how to process, but that the host header string also controls. Remember, this discussion all started with trying to figure out how useIPVHosts is supposed to work. Please provide a detailed description of how Tomcat function with useIPVHosts set to true, or provide a link which does.

apache 2 + tomcat 6 virtualhost question
Hello I'm new to tomcat and i have some experience with apache, i have a debian server with apache 2.2 + mod_jk and tomcat 6 server. My doc root for my site is /home/mydomain/htdocs and i have a site which is using a WAR which i deployed it via the tomcat manager. So far if i go to http://mydomain:8080/myapp it shows fine, but now what i need is that if i type www.mydomain.com it has to show the app directly. I've managed to create an htaccess with a 301 redirect to the url http://mydomain:8080/myapp as a temporal fix, but what i need is that when i type www.mydomain.com it goes to my app and stays with the mydomain.com url. How can i do that? do you need any config file? any help is appreciated. Thanks in advance. -- Patricio Lpez Salgado Jefe de Operaciones 2-697 9216

RE: Tomcat 6.0 always uses default host in multi-host config
Thanks for working through this with me Chuck. Sorry for the frustration. Probably should have started MY inquiry off as a new thread. Now that I got how useIPVhosts works (probably), did you see any drawbacks to setting up multiple Services to achieve what the original poster was going for, i.e. multiple hosts with unique SSL certificates? (other than the obvious amount of typing involved) I'm thinking technical performance issues. I can see the usefulness of using useIPVHosts instead of multiple services if one is using SSL. Only one port 80 connector to handle the non-SSL traffic. For an everything SSL setup, that's a benefit for the initial non-SSL connection that gets redirected to SSL. In fact, I'd say the only real need for it is when you are doing SSL and can't use a wildcard-SSL cert, e.g. www.example1.com, www.example2.com, etc. Just have to remember that hostnames in the server.xml are primarily for documentation, and you really need an Alias for the IP address.

RE: TC security/impersonation question
Hi, Just a dumb question from a newbe but if I implement any type of security with TC then under what identity will the invoked WS stack object execute the request? Specifically, if I enable Kerberos authentication between the requesting application and TC does this guarantee the WS stack executes the requestor's request under the identity of the actual originating requestor? Much appreciated, Tim. The New Busy think 9 to 5 is a cute idea. Combine multiple calendars with Hotmail. Get busy. _ Hotmail is redefining busy with tools for the New Busy.

In that case you can have one tomcat instance per application. Each application can run inside its own tomcat process and have different ajp port, mod_jk worker and apache virtual host.

Re: Tomcat 6.0 always uses default host in multi-host config
Allow me one more attempt at a clear doc? 1) If useIPVHosts=false (default), then the host header name determines Host for processing, or default host of the Engine. 2) If useIPVHosts=true, then IP address of request determines Host for processing, providing the IP is provided as the host name, or Alias. If not found, then default host of Engine applies. The actual rule is that Tomcat uses the value of request.getLocalName() to determine the Host. So this is not completely true if you are using an AJP connector. In this case, Tomcat uses the ServerName for the VirtualHost that Apache picks. So if Apache is using named virtual hosts, they you get the one that it resolved to in Apache. If you are using a HTTP/1.1 connector, then this is the name that the IP address resolves to on the machine where Tomcat is running. The useIPVHosts=true is useful when running with an AJP connector if you have a lot of ServerAlias directives and/or change them often. It means that the admin only needs to make the change to Apache without having to make the corresponding change to Tomcat. 3) Nothing external to server.xml matters to Tomcat in resolving Host for processing. Well, not other than DNS resolution for a HTTP/1.1 connector when using true. If you change the DNS name of the machine, then you need to change server.xml as well. Does that sound accurate?

Thanks guys for you replys,
Carl - Please update this thread with results of your check for 6u20.
I've decided to install x86 version of JDK - jdk-6u7-linux-i586.bin
(stability is my main concern now)
So in my installation I just installed jdk-6u7-linux-i586.bin version.
1. Changed symlink:
# rm jdk
# ln -s jdk1.6.0_07 jdk
2. Updated paths with:
# alternatives --remove jar /srv/jdk1.6.0_18/bin/jar
# alternatives --remove java /srv/jdk1.6.0_18/bin/java
# alternatives --remove javac /srv/jdk1.6.0_18/bin/javac 100
# alternatives --install /usr/bin/java java /srv/jdk1.6.0_07/bin/java 100
# alternatives --install /usr/bin/jar jar /srv/jdk1.6.0_07/bin/jar 100
# alternatives --install /usr/bin/javac javac /srv/jdk1.6.0_07/bin/javac 100
# /usr/sbin/alternatives --config java
There are 2 programs which provide 'java'.
SelectionCommand
---
*+ 1 /srv/jdk1.6.0_18/bin/java
2 /srv/jdk1.6.0_07/bin/java
Enter to keep the current selection[+], or type selection number: 2
# java -version
java version 1.6.0_07
Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
Java HotSpot(TM) Client VM (build 10.0-b23, mixed mode, sharing)
3. Updated setenv.sh to some basic defaults:
# cat /srv/tomcat/bin/setenv.sh
export JAVA_HOME=/srv/jdk
export PATH=${PATH}:${JAVA_HOME}/bin/
# CATALINA_OPTS=-server -XX:+UseParallelGC -Xms2048m -Xmx2048m
-XX:MaxPermSize=1024m -XX:+CMSClassUnloadingEnabled
-XX:+CMSPermGenSweepingEnabled -Djava.awt.headless=true
CATALINA_OPTS=-Xms512m -Xmx1024m -XX:MaxPermSize=512m $JAVA_OPTS
-Djava.awt.headless=true
export CATALINA_OPTS
export CATALINA_PID=$CATALINA_HOME/tomcat.pid
I'm going to monitor this server and see how it goes.

The current JVM version is 6u20, so you might want to try running with
that before filing a bug report or expanding the swap file.
Should also mention that another Tomcat admin reported occasional but
persistent abrupt terminations of the 1.6 JVM on levels 6u10 and above, but
went back to 6u7 and that appeared to rectify the problem. I think the
highest level he had tested was 6u17, but I'm not positive.
