And the jsp websites will sit in seperate physical folders on the server, for example: C:\website1\ C:\website2\ A simple answer to your question is to create additional Host entries to your Tomcat server.xml file. That's the way to go. While I know that there are some on this list who disagree with this method, I personally find that configuring hosts and contexts in the server.xml file very simple as it makes adding new hosts to Tomcat similar to adding new hosts in Apache. Hosts are usually configured in server.xml (unless you use some kind of dynamic/programmatic configuration). With contexts, it's not some on this list who disagree, it is Tomcat developers discourage this method in the official documentation. It still works as of Tomcat 6 and 7 though. Host name=ourserver.com appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Context path= docBase=C:\website1\ / Aliaswww.ourserver.com/Alias /Host You can achieve the same with: tomcat/conf/server.xml: Host name=example.com appBase=example.com-webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Aliaswww.example.com/Alias /Host tomcat/conf/Catalina/example.com/ROOT.xml: Context docBase=C:\website1\ / Notes: * appBase must be different for every host. Better take care of that even if you mean to deploy outside the appBase. appBase can also refer to a path outside the tomcat directory structure. * if you need/want the Tomcat manager app, you need to deploy it in each host * if you have no specific reasons for your directory structure (like existing backup or fileserver infrastructure), you can as well deploy into appBase, with your webbapp in a directory named appBase/ROOT or in a .war file named appBase/ROOT.war and discard above mentioned ROOT.xml. It will more closely match what other tomcat users/admins are used to and function the same way. And Tomcat will now know how to resolve each domain to it's own directory rather then inside the ROOT webapp. There are other ways to configure contexts, which I'm sure folks will post about subsequently, but I've found this works quite well and whether it's the proper way to do it or not, it will solve your problem. The/one major drawback is: you need to restart Tomcat completely for any webapp context that's added/deleted/reconfigured. I also don't see that much of an advantage compared to context.xml config files. I think there's something to do with $CATALINA_BASE that I need to configure, but I don't know how. You need to do that only if you want to run a separate tomcat instance for each webapp. Each instance has its own Tomcat configuration, and its own JVM. Use it only if you need/want that.

Hi Olaf and Brett,
I already made those changes similar to what is mentioned here --
http://spiralbound.net/blog/2008/03/17/rhel-system-configuration-changes-for-oracle-10g,
it appears that the changes improved the performance, the system no
longer chokes. However I still want to optimize other settings like
JVM configuration to further enhance systems performance,
unfortunately I have where to find the JVM config.
It depends whether you're using the RedHat supplied (or EPEL) tomcat RPM
or a download from Apache.
(a) downloaded from Apache (I use this):
Read the RUNNING.TXT (for background info).
JVM configuration for Tomcat is usually in setenv.sh which is normally in:
$CATALINA_BASE/bin/setenv.sh
(CATALINA_BASE == CATALINA_HOME by default)
(b) RHEL5 supplied RPM
Environment variables are configured in the file:
/etc/sysconfig/tomcat
In either case, the environment variables you need to set are:
CATALINA_OPTS: used during START only
JAVA_OPTS: used during both START and STOP operations.
Normally JVM heap size, GC logging etc are set in CATALINA_OPTS
since they are only valid on START operations.
The only thing I normally place in JAVA_OPTS is:
-Djava.awt.headless=true and library path (if running on X86_64
systems)
Sample setenv.sh is included below (X86_64, RHEL5, Tomcat 6.0.30) YMMV:
In my configuration I have simple wrapper start/stop scripts that set
the following environment variables prior to calling
catalina.sh start / stop. This permits multiple Tomcat instances on a
single server. Very difficult to do with stock RHEL5 Tomcat RPM
CATALINA_HOME=/opt/tomcat6(points to where binaries are installed)
CATALINA_BASE=/home/tomcat/tc1 (points to instance)
CATALINA_PID=${CATALINA_BASE}/temp/tomcat.pid
-- ${CATALINA_BASE}/bin/setenv.sh --
CATALINA_OPTS=-d64 -Xmx2048m -XX:MaxPermSize=384m \
-Dcom.sun.management.snmp.port=xxx \
... other jmxremote / snmp parameters as needed \
-verbose:gc -Xloggc:${CATALINA_BASE}/logs/gc.log \
-XX:+PrintGC -XX:+PrintGCDetails -XX:+PrintGCTimeStamps \
-XX:HeapDumpPath=${CATALINA_BASE}/temp \
-XX:+HeapDumpOnOutOfMemoryError \
-Dorg.apache.catalina.startup.EXIT_ON_INIT_FAILURE=true \
-DjvmRoute=jvm1
JAVA_HOME=/usr/lib/jvm/java
JAVA_OPTS=-Djava.awt.headless=true -Djava.library.path=/usr/lib64
Good luck!
Cheers!

CLOSE_WAIT is normal behaviour - after a TCP socket is closed, it's tombstoned for a period so that the TCP stack knows what to do with incoming datagrams that might be late. Peter, I do not think that this is true, and I believe that you are confusing this with the TIME_WAIT state. See for example this : http://support.microsoft.com/kb/137984 CLOSE_WAIT: A socket application has been terminated, but Netstat reports the socket in a CLOSE_WAIT state. This could indicate that the client properly closed the connection (FIN has been sent), but the server still has its socket open. This could be the result of one instance (among all threads or processes) of the socket not being closed. I had/have a case like that with a third-party Tomcat application. It goes typically like this : The webapp creates an object C which among other things makes a TCP connection to another server. The webapp then uses this object's methods to send/receive data from the other server. At the end of this exchange, the webapp sends a command to the external server, to tell it I'm done. The external server then closes its end of the connection. Now the webapp, by means of closing the connection, sets the object C = null. For the webapp, this means that the connection object C is now effectively closed. But in fact, the object C still exists somewhere on the heap, and it still holds on to its underlying (OS-level) socket, which has never been closed from the Tomcat server side. The underlying TCP connection is in the CLOSE_WAIT state, because the socket has never been closed on the Tomcat server side, and it remains dangling. It only disappears when the Tomcat JVM does a GC, and the Object C is really discarded. That really closes the underlying TCP socket, and then the state progresses LAST_ACK and finally CLOSED and gone. An easy way to verify if this is the case of the OP, is to force Tomcat to do a GC, and see if these CLOSE_WAIT connections then disappear. If it is the case, then I would advise the OP to check his webapp, to see if it does not do the same kind of thing as described above. One problem that I have seen happen with this, is that as the number of CLOSE_WAIT sockets increases (to a few hundred), the whole server becomes unable to handle further TCP connections of any kind, being in the practice paralysed. I suppose that there must exist some inherent limit as to the maximum number of sockets which a system (or a process) can have active at any one time. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

The answers to these questions may help us help you: What linux distribution and version are you using? If you point your browser at http://localhost/ what happens? If you ls /etc/init.d/ what files do you see? Tomcat can be configured to serve html files. Some people prefer a dedicated http server (such as Apache HTTP Server) in front of Tomcat, passing just the java server requests to Tomcat. If you don't know why you need one (your boss said so, you have to coexist with other application platforms, etc) then you probably don't. You can always go back and add the http server later. Please tell us what you specifically need to do.

Lava, you have not told us which version of Tomcat (or Apache httpd) you are using, on which exact platform, with which version of Java, nor anything really about where these different packages come from or how or where they are installed. You also seem to be relatively confused about what Apache Tomcat and Apache httpd really are, and how they can communicate with eachother, or even if they need to communicate with eachother and why. There are probably 30 different types of Linux, and several hundred types of boxes on which to run it.

Re: apache question
Hi everyone, I'm sorry for not providing the system informations earlier, the linux I'm using is centos 2.6.18 and the apache tomcat is 7.0.4 java is 1.6.0_22 I know the difference between apache tomcat and apache httpd, I need to configure apache httpd to server as a proxy, I just want to know is apache httpd comes with apache tomcat when you download it, as I mentioned before I see there is httpd in /etc but I don't see apache in the /opt so does that means I need to download apache ? and my second question is how to upload a html ( embedded with java script )web page into apache ?

Re: apache question
In centos the file /etc/httpd/conf/httpd.conf should be the
configuration for the Apache HTTP Server. For information on that
configuration please write to the apache users list. One quick tip,
assuming you have no virtual hosts set up, the DocumentRoot directive
will tell you where to put your html files.
To pass java server requests to Tomcat you can install mod_jk. You
should be able to find an rpm to do this for you. Once it is
installed, you'll need to use JkMount directives in the httpd.conf
file to tell Apache Http Server which requests to pass to Tomcat, for
instance:
JkMount /*.jsp ajp13 # pass jsp file requests
JkMount /*.do ajp13 # pass struts app requests
JkMount /manager/* ajp13 # pass manager app requests
The ajp13 token above is the name of a worker configured in your
{tomcat root}/conf/workers.properties file.
This will help I hope:

Unregistering context mbean twice
Hi, There, I hope someone can help me with the problem I have with undeploying a webapp. We recently upgrade from 5.5 to 7 and whenever I undeploy our web app, I will get an exception like this: Feb 1, 2011 4:27:13 PM org.apache.catalina.util.LifecycleMBeanBase unregister WARNING: Failed to unregister MBean with name [Catalina:j2eeType=WebModule,name=//localhost/report,J2EEApplication=none,J2EEServer=none] during component destruction javax.management.InstanceNotFoundException: Catalina:j2eeType=WebModule,name=//localhost/report,J2EEApplication=none,J2EEServer=none I debug into tomcat code. And what I found out is that the context Mbean is first unregistered by ServerLifeCycleListener when it handles remove child event. JmxMBeanServer.unregisterMBean(ObjectName) line: 506 MBeanUtils.destroyMBean(NamingResources) line: 1358 ServerLifecycleListener.destroyMBeans(NamingResources) line: 832 ServerLifecycleListener.destroyMBeans(Context) line: 655 ServerLifecycleListener.processContainerRemoveChild(Container, Container) line: 1044 ServerLifecycleListener.containerEvent(ContainerEvent) line: 107 StandardHost(ContainerBase).fireContainerEvent(String, Object) line: 1261 StandardHost(ContainerBase).removeChild(Container) line: 960 HostConfig.checkResources(HostConfig$DeployedApplication) line: 1178 HostConfig.check(String) line: 1347 But the standardContext will unregister the same bean again when it's destroy method get called after that ServerLifeCycleListener handles remove child. That is why the exception: JmxMBeanServer.unregisterMBean(ObjectName) line: 506 StandardContext(LifecycleMBeanBase).unregister(ObjectName) line: 191 StandardContext(LifecycleMBeanBase).destroyInternal() line: 73 StandardContext(ContainerBase).destroyInternal() line: 1116 StandardContext.destroyInternal() line: 5351 StandardContext(LifecycleBase).destroy() line: 285 StandardHost(ContainerBase).removeChild(Container) line: 969 HostConfig.checkResources(HostConfig$DeployedApplication) line: 1178 HostConfig.check(String) line: 1347 These two happened in one call to HostConfig.check. I didn't see anyone else report the problem, so I think I might not configure the server correctly or my program might be not coded right to undeploy an web app. But I did study the Managerservlet comes with tomcat which handle deployment and undeployment. I didn't see any significant difference. I also copy the code. I still get the same error. I notice in tomcat 5.5 source code. The code for unregister context mbean in ServerLifeCycleListener is commented out. That is why we don't have the problem in 5.5. Hope someone can tell me what I did wrong. Thanks, Ming

No. I am looking for a possible workaround to create shared connection pools without modifying server.xml (ie placing entries in GlobalNamingResources .../). JMX is probably your best bet but I don't think the necessary API is exposed. As always, patches welcome. If a web application could populate into the global namespace, then I could devise a WAR which defined the desired connection pools and placed them in the global namespace. Other web applications could then retrieve them as if they had been defined in server.xml. Apart from the fact that web application start order is undefined... Lots of things to go wrong here. If two apps define the same resource, which wins? I'm fine with the JMX bit but much less comfortable with apps using it directly.

I usually get:

But sometimes I get this:
You have run into a java.lang.ClassNotFoundException:

Any idea what I'm doing wrong? From what I can see, my code seems to mirror

Re: Unregistering context mbean twice
2011/2/3 ming_ch...@mcafee.com: Sorry. I forgot give the exact version. It happens on both 7.0.4 and 7.0.6. I cannot say about 7.0.6, but with the current sources I do not observe any problems. You may try to build a version by your own, or wait for 7.0.7 -- I think it will be tagged built soon. Hope someone can tell me what I did wrong. First you have to tell us more about what you did. Is your configuration (server.xml) different from defaults? Is this issue reproducible? Does it happen with the default Tomcat apps, or it is specific to your webapp? Any other errors or warnings in the logs? Best regards, Konstantin Kolinko - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: Optimize CPU Hogging Tomcat 6

However I still want to optimize other settings like JVM configuration to further enhance systems performance, unfortunately I have where to find the JVM config. You never told us how you know that your JVM process is the one using all the CPU time. If you run out of file descriptors and connections cannot be made, I would expect that you'd get an app that was doing virtually nothing. If all your threads are idle, where is the CPU being used? That error message about having too many open files shouldn't be too much of a big deal: the server should continue operating and should give you an error each time your usage peaks such that you accept one-to-many HTTP connections. You said you only have 30 users, though. What does netstat show? Do you have lots of lingering connections? How many request processing threads do you have configured in your Connector? - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk1J6OgACgkQ9CaO5/Lv0PCRegCfVh6bv/kbTKebKQqm8e7Jp+rE +RYAnj1XNJPXjc7wQA6/b2Uc2FyEcnCc =TvH/ -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: Trouble with connection timeout settings

The JDBC API has overloaded methods for Statement.executeQuery and friends that all take timeouts. It's possible that your database allows you to set a global (or session) timeout for all queries, but that's beyond the scope of anything Tomcat could provide for you. Is there any setting that will cause Tomcat to kill a thread if that thread is stuck? Tomcat can't tell the difference between a thread that is doing something useful or something not useful: only you can tell the difference. You are welcome to write some kind of sweeper thread that examines each thread at an interval and makes some objective (or subjective, I guess) decision about the state of the thread and call any number of methods on it including interrupt(), etc. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk1J6tkACgkQ9CaO5/Lv0PBzWQCgwsfm2besCJMPYs5x3gS3sKHN hgYAoJrYh5Dz5o+X8Dam+BEDpg9rTQja =iqvn -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Multiple struts action servlet mapping 404ing behind Apache with Tomcat 7.0.6
I'm looking for a way to allow us to rename our .do struts extensions to something else, without having to do them all at once. Tomcat 7.0.6, jdk1.6, solaris 10, behind Apache 2.2.10, struts 1.1. Multiple struts action servlet mappings (*.do and *.foo) seems to do what we want when going through the tomcat port, but when going through apache, we get a 404 on .foos Any ideas appreciated. Thanks in advance.

Thanks in advance. You say Tomcat behind Apache, but you do not say what you use to connect them. mod_jk ? From your sketchy description, it looks like you may just have forgotten to proxy *.foo URLs to Tomcat, and Apache is trying to serve them locally (and not finding them). If your Apache configuration includes statements like JkMount /*.do workerx add a JkMount /*.foo workerx and restart Apache. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
