RE: Tomcat dependency on application server
Thanks Chris for your answer. There were separate PID's on Linux for JBoss Tomcat and I killed the Tomcat process. Would killing a Tomcat process also kill the JVM process? I had another related question of how to know the number of JVM's running, I mean the count of the number of JVM's. I hope, my query has been put across correctly. Requesting a reply.

RE: Tomcat dependency on application server
I have 1 observation. In our developmental environment, I killed the Tomcat process and started the Tomcat it worked. But in the production environment, starting Tomcat was not enough and I had to restart JBoss Tomcat in sequence for Tomcat to be up. Could it mean that JVM is crashing or something because of OOME in Tomcat. I could try to increase the heap Permgen memory in Tomcat, would that help? Requesting a reply.

Re: denying the request if it comes through IP address instead of DNS
dku...@ccilindia.co.in wrote: Hello All, We are using - Tomcat Version - 7.0.22 Operating System Version : Windows 2003 server To close a vulnerability, To denying the request if it comes through IP address instead of DNS, we have made below configuration changes in server.xml Engine name=Catalina defaultHost=server DNS name defaultHost was set to localhost prior to change Host name=server DNS name appBase=webapps unpackWARs=true autoDeploy=true Hostname was set to localhost prior to change But Due this change we are losing logging in localhost.log in logs folder of TOMCAT, Please suggest how to redirect console logging to a given file or how to retain the localhost.log file of tomcat. Kindly also let us know instead of above settings any other configuration setting will make denial of any request if it comes through IP address instead of DNS, Hi. What you really need first, is to understand how virtual hosting works, in HTTP webservers in general. HTTP requests do not come through DNS or come through IP address. They all come in the same way, through a TCP/IP connection established by the browser, to the IP address of your server. In short, what you did above was not the right way, for what you seem to want. What you should have done is this : 1) start from a standard configuration again 2) leave the Host name=localhost as it is (also in the Engine tag) 3) *add another* Host name=the DNS name appBase=(another path to the real webapps) That is where your real applications should be. (and a few more details not entered into here) Then what will happen is : - any request addressed to the DNS name will be processed by the second Host (the one that you added). That is where your real webapps should be. - any request with another hostname (or IP address) will be processed by the default host (the one named localhost). That one should then just have a default webapp, which answers forbidden or something like that. For more details, search Google for tomcat virtual hosts. I found a reasonable basic explanation here : http://www.ramkitech.com/2012/02/understanding-virtual-host-concept-in.html - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I'm trying to monitor various data about the application, not about tomcat itself or the JVM.

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: Tomcat dependency on application server
Really, there are about 1 gazzillion valid ways to setup an application consisting of n number of tomcats and m number of jbosses, running in same or separate processes/vms/datacenters and doing stuff. Maybe you should first find out, what your deployment architecture is, and what your app does. Probably ps is a good way to start to find out what is really running on your machine and where.

jsf validator not found when using maven tomcat 7 plugin
Hey guys, I'm developing a web application using latest version of spring 3.2 and latest version of jsf 2.2 (on Mac Mavericks). I defined a custom validator and give it an id using the faces exception annotation. If I run the application from Netbeans with the same tomcat version it works fine, if I run it from command line using mvn package tomcat7:run, the app starts and I get the javax.faces exception that my custom validator is not defined. Do you know if I have to do something different when running from maven? Thank you, Iulian
