First, is there a standard API that would work also in other J2EE containers besides Tomcat? As Bob suggested, ServletContextListener is the way forwards. Thank you for your replies. I did see ServletContextListener (as well as LifeCycleListener, etc. etc.). What I couldn't find out is how to obtain an instance of the object that would support an 'addServletContextListener' method. For instance, if you look at http://java.sun.com/products/servlet/2.3/javadoc/javax/servlet/ServletContextListener.htmlit says: To recieve (sic) notification events, the implementation class must be configured in the deployment descriptor for the web application. This doesn't sound like an API to me, it sounds like a configuration option, so it doesn't answer my question. Is it true that there is, basically, no API a web application can call at runtime to add such listeners? The most likely candidate to which to add a ServletContextListener would be a ServletContext, but it doesn't appear to support an 'addListener' method, unless I'm overlooking it: http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/ServletContext.html Second, is there a custom API in Tomcat? Actually yes, but as you might imagine, there are restrictions. http://tomcat.apache.org/tomcat-6.0-doc/config/context.html#LifecycleListeners I saw that too, but again, it doesn't answer my problem. On the page you quote it says: The class name you specify must implement the org.apache.catalina.LifecycleListener interface, and the class must be packaged in a jar and placed in the $CATALINA_HOME/lib directory. I am interested in a solution that does not require access to the $CATALINA_HOME/lib directory. This directory is accessible only to the Tomcat administrator, and I would like my web app - if possible - to be deployed even in scenarios where the Tomcat configuration cannot be changed. And lastly, this solution would not work because the LifecycleListener itself would not be reloaded, since (to my knowledge) jar files in $CATALINA_HOME/lib aren't reloaded. I'm really interested in a solution that would be contained inside the web application (i.e., first or second above) and that would not require changes to the server configuration, so that it would work in hosted environments where I do not control the Tomcat configuration. I'm using the latest 6.0 release (6.0.20). 6.0.26? 6.0.24, actually. Thank you for your insights. - Godmar
Re: Tomcat 6.0 clustering problem with replication mode.
The first error
java.util.ConcurrentModificationException
happens cause the membership changed in between. The error logs, but the
system is not interrupted.
The second error
java.net.SocketTimeoutException: Read timed out
This means the node failed to respond. This means you got a problem. You
should post
- your exact tomcat version
- your configuration
- your jvm version

Tomcat on AIX 5.3
Hi, I installed Tomcat 6.0.26 in an IBM P6 LPAR . The java version is 1.5.0 that is equivalent to Java 5. The LPAR has 12G memory and there are two databases on it, a Sybase and a MySql. Sybase takes 3 G and mysql takes 3 G, so there is still plenty for Tomcat. The idea to put Tomcat here, was, that the webapp is connecting to the Sybase database on this LPAR, so getting the data locally should be faster than getting it via the network from another machine running Tomcat. Interestingly it is not the case. When the same webapp deployed on the LPAR and on the other machine - an OSX Server 10.5.8 -, the screens on a client machine are coming much faster from the OSX server compared to the AIX LPAR. Is there anything special configuring Tomcat on AIX than on OSX ? On both machines the memory settings are the same for tomcat : CATALINA_OPTS=-server -Xms512M -Xmx1024M and on AIX the option to use the IPv4 Stack is set in JAVA_OPTS. None of the .xml files were modified in the conf directory.

Re: Tomcat on AIX 5.3
Filip, What tool - java based or aix based -, can I use to see where does the time go ? /I am not a Java programmer/ I do not think it is the webapp, or tomcat, because the same configuration is fast on OSX server. DNS is working fine. Thanks ahead, János On Apr 14, 2010, at 11:28 AM, Filip Hanik - Dev Lists wrote: you'd have to figure out what takes the time.

Re: Tomcat on AIX 5.3
Janos, there are no clues that the delays are caused by tomcat, so maybe you should look in general at other causes of delays. There are a multiple components in the chain that can cause delays, networking, IO, CPU. You did not mention how much CPU you have at your disposal on your P6 machine, maybe you can have a look with IBM's nmon tool, contact your AIX support colleagues. And if your application has logging (maybe you can increase loglevels), that is the first spot to look at, that should give you a clue where the delays are. regards, Harry 2010/4/14 János Löbb janos.l...@yale.edu Filip, , What tool - java based or aix based -, can I use to see where does the time go ? /I am not a Java programmer/ I do not think it is the webapp, or tomcat, because the same configuration is fast on OSX server.
