RE: Virtual Hosting with WAR files
Thanks to all.
This setup has been tested on Apache2+JBoss+mod_jk-1.2.14_for MacOSX. And
am sure it will work on other platforms as well. This setup also handles
Apache related webapps..
Make the required entries in the DNS
webapp.war: Extract the war file using zip and rename the folder
with .war extension. Please put it in your deployment folder.
mod-jk.so: Obtain the modjk.so library file from www.apache.org and place
then in the modules folder.

Re: Advice for Hosting Many Individual Webapps?
Hi, I very often deploy client's applications in multiple tomcat instances. It is normal and each application does not affect another. You just need a strong multiprocessor server with a lot of memory to sustain the last :) The only difference is that I often configure a separate apache instance for each tomcat instance. But one apache is also fine. I find this setup very comfortable when it comes to updating the application code or just restarting an application. Also, when one tomcat crashes, others run just fine. A tip here is to write/rewrite startup script so that it handles multiple instances of tomcat. It is also a good idea to create an environment profile file for each instance where you define stuff like JAVA_HOME or JAVA_OPTS for each instance separatelly and store it with the configuration. The development expense may be unneccessary if you only have one setup like that. I hope you are using the $CATALINA_HOME and $CATALINA_BASE variables to separate binaries from runtime/configuration files of each instance and you're not copying the whole tomcat tree. Think about file and process ownerships when web applications belong to different owners. If you want to ensure reliability then clone the machine and put a redirector in front of both. It scales very well and the user impact in case of trouble is not 100%. --Radek W. Seth Ladd wrote: Hello, We are finding outselves hosting more and more individual webapps, all running on Tomcat 5.5.9 w/ JDK 1.5. Each of these webapps is developed and deployed on a separate schedule, and the number and frequency of app deployments is increasing. The frequency is so much that the uptime of all of our applications is affected as we continually take down Tomcat servers in production to deploy a new application (or new version of the application). Because hot deploy does not work (the old favorite OOM error w/ too many redeploys), we bounce the Tomcat server for every redeploy. To avoid taking down all of our applications when we need to redeploy a single app, we've begun to deploy each application to their own Tomcat instance. All of these instances are fronted by a single Apache server handling vhosts, logging, etc. We're just curious how common this setup really is. We know we are in an uncommon position, with so many webapps (approaching 20, and growing very fast). We don't want to put all our eggs in one basket, so to speak, so we've begun to split out individual tomcat instances. Anyone else have to handle numerous webapps, with frequent deploys, and have to keep uptime for all apps as high as possible? We hesitate to put all webapps in one tomcat, because to deploy one app means we have to take down all of our apps. This is becoming unacceptable. (not to mention that a memory leak in one app will bring down all the apps living in that tomcat instance) Any tips or tricks would be really appreciated. Or pointers to previous material (I've found some, but nothing that jumped out at me).

RE: Calculating required memory
From: Oleg [mailto:[EMAIL PROTECTED] I am trying to approximate the amount of memory my server will need running tomcat. I understand that a lot depends on how the appication handles resources, however at this point I am trying to figure out what will be the mimimum needed. In my case I have virtual hosting setup, with all hosts sharing the same libraries, so I have struts, hibernate,... all sitting in shared/lib directory of Tomcat. Would I be correct to estimate that Tomcat will atleast need n(number of users/applications) * mb(total size of shared/lib) As Chuck has already pointed out, no (but I'm going to try a slightly different angle on it :-) ). Each class that is loaded from shared/lib will be loaded by the Shared classloader, so you'll only have one copy of the class in your JVM. Jars are compressed, so the sizes of the loaded classes will be larger than the bytes occupied on disk; but not all of the classes from a jar will be loaded, so the sizes will probably be smaller. Note, however, that any classes in the webapp's WEB-INF/lib *will* be loaded once per webapp. If you have large numbers of applications, you may want to put more common libraries in shared/lib, and you may also wish to increase the size of the permanent generation (PermGen) in the JVM's memory model as this is where the classes are stored. Your per-session and per-page data will dwarf the space required for classes; and, as Chuck pointed out, the only way to find out these sizes is to profile the app. This will also make sure that you're not going to fall foul of any other performance limits, such as CPU use or disk bandwidth. - Peter - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: persistence with sessions distributable attribute
Hi Nishant,
where did you read that distributable will *enforce* serializability?
AFAIK distributable only means that your sessions can be distributed
to different tomcat nodes (i.e. a cluster). It doesn't enforce anything,
you have to make sure that your session attributes are serializable by
yourself.
I've done this for my testing environment with a SessionListener:
public class SessionListener implements HttpSessionListener,
HttpSessionAttributeListener {
private ObjectOutputStream stream = new ObjectOutputStream(new
OutputStream() {
public void write(int b) {}
});
public void attributeAdded(HttpSessionBindingEvent evt) {
if (LOCAL_DEBUG) {
// try to serialize attribute
Object o = evt.getValue();
synchronized (stream) {
try {
stream.writeObject(o);
} catch (IOException e) {
System.err.println(evt.getName() + is not serializable: +
e.getMessage());
e.printStackTrace();
}
}
}
}
...
}
I disable LOCAL_DEBUG in the production environment, because trying to
serialize every attribute is probably to expensive under heavy load.
@Lintang:
That wouldn't help any. If you put your attributes (which are not
serializable) into a HashMap (which CAN (!) be serializable) the
resulting object (map + attribute) still wouldn't be serializable.
Serializable is more than just implementing the java.io.Serializable
interface.
greetings,
Christoph
Lintang JP wrote:
hi Nishant,
You might want to put all your session variable inside HashMap or other
datatypes that implements Serializable, rather than put it just in a single
variable. Refer to the javadocs, what are those Serializable data types are.
Or maybe you can build your own class with something like this :
public class StoredSessionValue implements Serializable {
// your session variable goes here
// your setter and getter method for those variables goes here
}
You did right on your distributable/ tags.

Hoping for some help from the tomcat experts on this list.
I want to ensure all objects stored in sessions are serializable.
I read that I can put the distributable/ tag in my web.xml file to
'enforce' this.
But I don't see any enforcing happening. I assumed it would throw
exceptions at runtime when I did 'setAttribute(xxx,
SomeNonSerializableObject)'.
I have put 'distributable' in
web.xml: web-app ... distributable/ ... /web-app
I also have the following in server.xml:
DefaultContext reloadable=true allowLinking=true

Store className=org.apache.catalina.session.FileStore

debug=5/
/Manager
/DefaultContext
Am I missing something? How is the serializability enforced?
Also another question: the serialization does not happen in the
directory i specify for Store above, rather it happens in the
$CATALINA_HOME/work/Catalina/* directories. Any ideas about this one?

Apache and Tomcat on separate hosts?
I finally got Apache2 + mod_jk2 + tomcat 4.1 working with tomcat doing vhosting on my laptop for development. The management said that is great that I should now roll it over to the dev servers before putting it into production. I started setting up everything and was down to creating the vhost in httpd.conf when I realized one fatal problem, Apache and Tomcat are on 2 separate servers. The way that I understand it, Apache finds a jsp page in it's docroot and if the host is in workers2.properties, it gets handed over to tomcat. If the webapp is not on the same box, how do you let apache find it to hand over to tomcat? My first thought was NFS, but the change control board frowns on any sort of filesharing among the servers. It's kind of important to get this properly working, is there any other way? Thanks.

As I know, mod_jk2 project is no longer maintained so it's better to switch to mod_jk. With our java apps, mod_jk has an issue that causes apache to crash every 3-4 days. mod_jk2 does not, so it's doubtful we will be changing.

Re: webapp loading order...
Well Tomcat is not likely to do this for you so you would probably need to structure the app2 to wait for a trigger from app1. You could have app1 POST to a servlet in app2 and have that be the trigger for the dependent steps. Or have app1 write to a file that app2 will poll until it sees a trigger value it is set to look for. Joe R. Lindsay wrote: You may be right in a perfect world, but well...

AFAIK distributable only means that your sessions can be distributed

you have to make sure that your session attributes are serializable by
yourself.
I've done this for my testing environment with a SessionListener:
public class SessionListener implements HttpSessionListener,
HttpSessionAttributeListener {
private ObjectOutputStream stream = new ObjectOutputStream(new

public void write(int b) {}

} catch (IOException e) {
System.err.println(evt.getName() + is not serializable: +
e.getMessage());
e.printStackTrace();
}
}
}
}
...
}
I disable LOCAL_DEBUG in the production environment, because trying to
serialize every attribute is probably to expensive under heavy load.
@Lintang:
That wouldn't help any. If you put your attributes (which are not

session problems when using mod_jk (1.2.14) load balancing
Hi - I'm unable to get mod_jk load balancing working. The usual mod_jk setup works just fine, but using a load balancing worker however, is not. [Oddly, my webserver crashed during testing of this, but that could very well be unrelated] The problem is with user sessions. The instances (nodes) do not seem to recognize an already established session with the user and are creating new sessions. It's possible that is a session-stickiness issue, but it appears like the requests are hitting the same instance, just not getting the previously established session. As a result, I can't even reliably login to my application. I created a session listener for debugging purposes and it reports -no- destroyed sessions, but plenty of newly created sessions on both instances that make up the cluster. The session IDs, I noticed, have the jvmRoute name attached to them, which should be a good sign. I have a webserver running Apache (1.3.33), mod_jk (1.2.14), and an application server running the cluster -- 2 instances tomcat (5.0.28) on different ports. I added a unique jvmRoute to both instances in the server.xml: Engine name=Catalina defaultHost=localhost jvmRoute=dev_alexis Engine name=Catalina defaultHost=localhost jvmRoute=noah_alexis My worker.properties loadbalancer settings: worker.list=load_balancer_test worker.load_balancer_test.type=lb worker.load_balancer_test.balance_workers=bl_worker_dev,bl_worker_noah worker.load_balancer_test.sticky_session=true worker.load_balancer_test.sticky_session_force=false worker.bl_worker_dev.type=ajp13 worker.bl_worker_dev.host=alexis worker.bl_worker_dev.port=9003 worker.bl_worker_dev.lbfactor=1 worker.bl_worker_dev.socket_keepalive=1 worker.bl_worker_dev.recycle_timeout=300 worker.bl_worker_noah.type=ajp13 worker.bl_worker_noah.host=alexis worker.bl_worker_noah.port=8063 worker.bl_worker_noah.lbfactor=3 worker.bl_worker_noah.socket_keepalive=1 worker.bl_worker_noah.recycle_timeout=300 Any ideas, things I could try would be much appreciated. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: persistence with sessions distributable attribute
I didn't say that distributables don't have to implement
java.io.Serializable. In fact they have to.
I just had the impression (from your first post) that you thought by
putting an non-serializable Attribute into a HashMap, the attribute
would become serializable, too.
Example:
If you want to put a java.net.Socket into the session the session won't
be distributable because Socket isn't Serializable.
But if you put the Socket object into a java.util.HashMap (which
implements Serializable) and put the map into the session, the session
still wouldn't be distributable. This is because to serialize the
session the HashMap and ALL its fields must be serialized. Because the
Socket object is now part of the map, this won't work.
Serializable is just a marker interface, i.e. the class just
declares that is it serializable.
You should read the Java Tutorial (somewhere in the JDK docs).
There is explained what Serialization really means.

mod_jk documentation
Before I go gripe too, too much, let me just say that the mod_jk documentation has improved immensely since I start looking into it. Some of it might be simplied by the fact that I no longer consider jk2 in the picture which seemed to be adding some confusion. I don't know who is responsible for updating the documentation, so thought I'd post here. The documentation that I'm referring to is at: http://jakarta.apache.org/tomcat/connectors-doc/index.html load balancing page: Well, the load balancing page is empty, which is ok, but a link to the majority of load balancing explanation on the worker.properties page would be nice. domain property for a worker. I had to use the domain property on a worker to get load balancing working, which corresponds to the jvmRoute. I didn't see any mention of jvmRoute or domain anywhere however in either the load balancing section or the general worker properties. finally, and this may have annoyed me more than anything else - all throughout the load balancing documentation there are red, bolded lines like These workers should not appear in the worker.list property! in reference to balance_workers. But then in the example, they do exactly what they said should NOT be done: (bottom of this page) http://jakarta.apache.org/tomcat/connectors-doc/howto/workers.html - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
JSP Precompilation
I am trying to use jasper2 to pre-compile the JSPs as part of build process. The compiler is complaining with the message: ERROR - the file 'blah/blah/jsp' generated the following general exception: java.lang.NullPointerException' After spending some time, i realized that the jsp files which had invalid usage of tags were the culprits. The errors disappeared after tag cleaning. Now this error is only coming for 2 files, and i am positive that there is nothing wrong with tags. What could be other possible reasons ? Is there any way of configuring the compiler to output detailed stacktrace, if it fails at any jsp file compilation. Tomcat version is 4.1. thanks, ramnish. ** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

Re: session problems when using mod_jk (1.2.14) load balancing
That should not work! The correct way to configure session stickyness is to use jvmRoute (which you already did) and then giving the workers the same names as the jvmRoute. That is instead of bl_worker_dev use dev_alexis and instead of bl_worker_noah use noah_alexis as the worker names. You should check, that the URLs produced by your application include the ;jsessionid=32Characters.jvmRoute or - in case you use cookies - the same info is in your session cookie. mod_jk then automatically strips the jvmRoute part from the session identifier and lloks for a worker of the same name. You will only need to use the domain attribute in case you have a lot of tomcat instances and some of them have the sessions replicated, others not. Then you can give all members of a replication domain the same domain name and mod_jk will know, that in case the correct worker is down, which alternatives are good. Beautiful - worked like a charm. That might take the cake as far as longest question to quickest, shortest answer goes. ha. Thanks a bunch. I might have to gripe about doucmentation in a second (nother thread)..

Re: Enabling CGI/Perl in Tomcat 5.5.9
I haven't tested any of this, I am working entirely from memory and the documentation. I think you have a security problem. As your system is configured a request for http://foo.bar.com/3gflex/3gcgi/somedir/myscript.cgi will look for the script at /usr/prod/3gflex/somedir/myscript.cgi but a request for http://foo.bar.com/3gflex/somedir/myscript.cgi will return the content of your script. You have two options. 1. Move all your cgi scripts under the WEB-INF directory. 2. Use extension mapping (which is now supported) rather than path mapping. The easiest fix will depend on how your application is structured. Extension mapping will look something like: servlet-mapping servlet-namecgi/servlet-name url-pattern*.cgi/url-pattern /servlet-mapping Mark A Madhusudan-A5324C wrote: Hi, I am facing some problems with enabling CGI in Tomcat 5.5.9.
