Are there issues with running multiple instances of tomcat?
We are currently running two instances of tomcat on our systems. One is for a vendor specific application and the other is for in-house written applications. We are careful to make sure the ports do not conflict and there are plenty of resources to support both; memory and CPU. Recently the statement has been made that the two instances can conflict with each other and cause issues and instability with the applications. Is this true? I was under the impression that since they are in their own JVM's neither tomcat would have any affect on the other. If there are issues in what form may they take place?

Regards Adding to Mladen's answer: if you have only one app per Tomcat, you can use the activation attribute of an LB member (active, disabled, stopped) to tell the LB, if it should send requests to the member. Look at "activation" in http://tomcat.apache.org/connectors-doc/reference/workers.html Another possibility is to use the attribute fail_on_status with a value of 503, because an existing but stopped Tomcat context will answer requests with http 503. You could check, whether 503 or -503 suites you better. See the same docs page. Starting from 1.2.27 there will also be a possibility to express an activation state in the mapping table uriworkermap.properties, which would allow to disable or stop a forwarding per URL and per node. Unfortunately the nsapi plugin doesn't actually support the forwarding via uriworkermap.properties. It only allows setting the uri to worker map via NameTrans in obj.conf. Something we could improve, but at the moment there seems to be no huge interest in the nsapi plugin.

That sounds like classic FUD unless the person concerned can back it up. Who's trying to pass the buck for a problem? The vendor or the in-house dev team? :-) > Is this true?

They'll compete for resources (notably disk i/o and the overall system cache), but I'm not aware of any other issues. I've seen one big production site run with three load-balanced Tomcats on one (big!) box, simply so that the organisation could restart one Tomcat instance at a time for upgrades.

Re: sessionListener.sessionDestroyed is called on shutdown of a node in the cluster
Yes, I know how to work around the problem. But I don't like workarounds. All
implementations I can think of are very fragile. What if somebody stops my
Tomcat with kill one day?
My session isn't destroyed, so I don't understand why the event is thrown.

Are your shutdowns typically planned? If so, you could stick something
in the session like "shuttingDown192.168.1.123" and then check for that
key when you are processing a "session destroyed" event. Just ignore
such events from the current machine's IP address.
Or, you could even do something like this:
1. Before shutdown, place a "shutting down" key in the application scope.
2. Modify your sessionDestroyed code to do this:
public void sessionDestroyed(HttpSessionEvent se)
{
~ ServletContext application = se.getSession().getServletContext();
~ if(null != application.getAttribute("SHUTTING_DOWN"))
~ return;
~ // Otherwise, process the shutdown normally.
}
This should work given that the application scope is not distributed
across nodes in the cluster. You just put your node in a "shutdown"
state and then ignore all events (or any you care to ignore).
Hope that helps,

Or if the session expires by timeout. Unfortunately, I was unable to find any detail in the servlet specification, which means that implementors are free to do what they'd like in these situations. On the other hand, it means that you might have an opportunity to lobby the Tomcat folks to add a configuration parameter (similar to expireSessionsOnShutdown) to achieve the behavior you desire. The problem is that sessionDestroyed can be used to support both resource release (kind of like a "finally" for sessions) as well as "logout" (in your case). For the former, it is very important for that event to fire, even on a single node being taken out of service. For others (such as yourself), it is inconvenient. It's hard to satisfy both requirements. The Tomcat folks seem to have erred on the side of inclusivity (always send the event) because there are possibilities to work around it. If the event were never sent, there's no way to handle resource release at all. Optional configuration sounds like a good choice. -chris Thanks for the explanation. I would implement the resource release stuff in a ContextListener or by ValueUnboundListeners, but that is another discussion. My problem isn't that big in practice. Just the accounting of logouts is not 100% correct. I'll think about something genius to work around it. If I can't think of anything I will try to lobby more. Ronald.

Problem to deploy my webbapps
Hi, I'm developing a web application with wicket framework, under tomcat 6.0.16 and jdk 6 update 4.

Are you *absolutely certain* you're not running Tomcat with an older JDK, such as a 1.5 JDK? If you search your machine for Java installations, is the JDK6 installation the *only* one? And I do mean search, using find (on UNIX) or Find Files (on Windows) - don't just look in the obvious places! What's your JAVA_HOME, if any?

RE: NotSerializableException: StandardSessionFacade
The exception says that the class that can't be serialized is StandardSessionFacade, which is an internal Tomcat class. That's what's confusing me. If it was a class in my code, I would know what to hunt for. Deleting work folder causes problem to go away. However, it will come back. Thanks for the response.

How to detect the database for JDBC Realm is down
Hi,
I am building a web app and have setup digest authentication
I am testing the app when I take the database that contains the username
password down
The tomcat log file show this
(http-8443-Processor25) org.apache.catalina.core.ContainerBase.[Catalina]:
Exception performing authentication {
java.sql.SQLException: No operations allowed after connection closed.
at com.mysql.jdbc.Connection.checkClosed(Connection.java:2647)
at com.mysql.jdbc.Connection.commit(Connection.java:1039)
at org.apache.catalina.realm.JDBCRealm.getPassword(JDBCRealm.java:563)
at org.apache.catalina.realm.RealmBase.getDigest(RealmBase.java:1091)
I have setup the WEB-INF/web.xml to trap this exception to show a custom
error page
java.sql.SQLException
/server_rdbms_error.html
however tomcat is not showing the custom error page and it keep popping up

Re: Are there issues with running multiple instances of tomcat?
David Brown wrote: We are currently running two instances of tomcat on our systems. One is for a vendor specific application and the other is for in-house written applications. We are careful to make sure the ports do not conflict and there are plenty of resources to support both; memory and CPU. Recently the statement has been made that the two instances can conflict with each other and cause issues and instability with the applications. Is this true? I was under the impression that since they are in their own JVM's neither tomcat would have any affect on the other. If there are issues in what form may they take place? David, That is an unfounded superstition. You can run multiple Tomcat (and different versions) on the same box. Your only constraint is the available disk/RAM/CPU resources. When you hear about private java hosting, it is essentially a single box running 30 to 100 installations. -- Regards Gabe Wong NGASI AppServer Manager JAVA AUTOMATION and SaaS Enablement http://www.ngasi.com NEW! 8.0 - Centrally manage multiple physical servers - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Custom Valve
I'm using Tomcat 6.0.14 and need to write a custom Valve to control the Domain property of the JSESSIONID cookie (so it will be reused on any subdomain) but I can't find any documentation on how to go about creating a custom Valve. Could someone please let me know if this is accurate? - extend the org.apache.catalina.valves.ValveBase class - implement the invoke method - package that up into a .jar file - put that .jar file into Tomcat's lib directory (alongside catalina.jar, etc) - edit server.xml to look like this: - restart Tomcat I've done all of the above, yet I don't see the desired effects of my Valve nor do I see any of its System.out.println statements in catalina.out but I'm not sure what I'm doing wrong. -- View this message in context: http://www.nabble.com/Custom-Valve-tp16764609p16764609.html Sent from the Tomcat - User mailing list archive at Nabble.com. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Large HTML file not getting compressed despite compression enabled
Okay, here's the bug: org.apache.coyote.http11.Http11AprProcessor:1504: response.getContentLengthLong() returns 4, instead of the true file size, making it appear lower than the minimum compression threshold.

Bending Jasper to My Will
I have been going through the Jasper source code to figure out how to make it do what I want but have been unsuccessful. So I thought I would ask the experts. (Please let me know if there is a better forum for this particular question.) I want Jasper to look for JSP and Tag files in a specific location (e.g. based on a request param); and then fall back to a default location if the file is not found. This would be extremely useful for skinning a webapp. Any ideas? -AndyC - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Custom Request Subclass
I'm using Tomcat 6.0.14 and I need to override the Request.configureSessionCookie method to call setDomain on the Cookie (so the session cookie can be shared across subdomains). Is there any way to tell Tomcat to instantiate & use my Request subclass instead of Request itself?
