RE: Tomcat dependency on application server
JBoss uses Tomcat as its Servlet container, so there should be no need for a separate tomcat. Can you let us know for what purpose you are using a separate tomcat. ___ Thks brgds P Manchanda On Sun, 18/5/14, Terence M.

I am asking this query because I had killed the tomcat process using kill -9 and while restarting tomcat it was not starting but when I killed JBoss tomcat and then restarted, Tomcat was up. I hope my query is clear whether Tomcat is dependent on JBoss. I'm fairly sure that there is only a single JVM for JBoss/Tomcat. If you killed one, you've killed the other. - -chris From what I've read, JBoss is based on a forked version of Tomcat and shouldn't need a separate instance of Tomcat to function.

Re: Application monitoring
Thanks Leon 1) You could use jmx and publish your information as jmx beans. That was the first thought I had. I would prefer using JMX beans, so that i can leverage any JMX tool like JConsole or JVisualVM ___ Thks brgds P Manchanda On Thu, 15/5/14, Leon Rosenberg rosenberg.l...@gmail.com wrote: Subject: Re: Application monitoring To: Tomcat Users List users@tomcat.apache.org Date: Thursday, 15 May, 2014, 19:27 Hello David, I will not ask you why you are reinventing the wheel (ok, I lied, why are you reinventing the wheel?). You have multiple options available: 1) You could use jmx and publish your information as jmx beans. 2) You could use rmi between you 'collector' and the target apps. 3) You could use simple http (preferably json), but in that case I would advice to setup a separate collector for it. For any of the above options there are numbers of classes and utilities you can use. For example jersey as jax-rs implementation is perfect for exchange of json data, for rmi you could use DistributeMe ( http://www.distributeme.org) or spring-remote, and so on. But yet again, why reinventing the wheel? regards Leon On Wed, May 14, 2014 at 6:28 PM, David kerber dcker...@verizon.net wrote: I am working on a small Tomcat servlet to monitor other tomcat-based applications running on the same physical machine, and am trying to figure out the best way to communicate between the monitoring app, and the monitored apps. My setup has several tomcat instances of a single application, each running from its own directory, and listening on its own TCP port. So there is no direct communication between the instances. I'm trying to monitor various data about the application, not about tomcat itself or the JVM. So I want to collect such things as the number of requests it has processed, the last data received, etc, and not things like memory and cpu usage. It is my app, so I can (and expect to need to) add methods or servlets to return the information I want to collect. My question is, what is the best way to make the request to get the data? Would URL request from the monitoring app to the monitored app be appropriate, and then parse the response out for display in a browser? If so, what java class is likely to be useful for this communication? I will have all the information needed to connect to the application instance (server, port, etc), but want it to be portable across OS types.

Re: Is Apache Tomcat v7/v8 compatible with Java v8
Respected Tomcat Experts, I understand this would be a commonly asked question but I was not able to reach any concrete solution by digging around the net. We are planning to move to Apache Tomcat (probably the latest stable version) and Java 8. So, my question is that whether Apache Tomcat v7/v8 would run with Java 8 and support applications build using Java 8. The Release notes (https://tomcat.apache.org/tomcat-8.0-doc/RELEASE-NOTES.txt), mention that Tomcat requires Java 7 or later. Similarly, a blog (https://spring.io/blog/2014/03/21/java-8-in-enterprise-projects) also claims (and explains why) Tomcat's compatibility. However, a discussion on SO (http://stackoverflow.com/questions/18208805/does-tomcat-8-support-java-8), has claims and counter claims regarding this. So, hoping to get a concrete confirmation -- either ways -- from this group. ___ Thks brgds P Manchanda - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
