Re: What exactly happens when I configure a different host
The real reason is I have 3 web apps I want to deploy in a single tomcat instance and all 3 have to be exposed with root context and also need to be running on port 80. Hence, I have chosen to give my machine that runs tomcat to have 3 distinct DNS Names/Addresses and configures these names/addresses as the Name. The 3 web apps are required to be running 80 all the time and also have to have a root context all the time too. I basically did this as this was a simple solution. However, I am interested in seeing alternatives for this approach.

Re: What exactly happens when I configure a different host
Whew.. that was a problem alright.. Does that mean when we change the , we have to have a handler added in logging.properties as well. ? I see there are already defined for applications packaged with tomcat like manager and host-manager.

Finally had time to go chase this a bit more. The error doesn't really "vanish" when the name is "localhost", but it is not sent to the console window Tomcat is using, nor to the catalina.*.log file; you can find it in the localhost.*.log file. When you change the name to something else, the error is displayed in the console window and in the catalina.*.log file, but not in localhost.*.log. The reason behind this apparently inconsistent behavior is the settings in conf/logging.properties: log entries for "localhost" are routed to specific handlers, which do not include the console window. When you changed the name but did not update logging.properties, the default log handler kicked in, which dumped the error message to the console. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: What exactly happens when I configure a different host
Yes. I changed the Name and defaultHost back to localhost and the error vanishes. However, it re appears when I give a different name than localhost.

Re: What exactly happens when I configure a different host
I extremely sorry for not being able to clarify to you. There is definitely a reference to the Log4jInitialiserservlet in my web.xml ( pasted above ). The servlet is missing in my jars/wars. . So i expect tomcat to throw error when it starts When tomcat starts with host name = "localhost", it does NOT throw any error about missing class file. But when i start with the host name = "blahblah" it throws the error. The question is why did not throw in the first case and why did it throw in the second. ?

Have you modified conf/web.xml at all? Delete everything under conf/Catalina to make sure there are no left-over elements pointing to webapps somewhere.

Re: What exactly happens when I configure a different host
The thing is this servlet is not present at all. It is wrongly being referenced web.xml. The original point of my question was just that.. When I configure host name as localhost ( which is by default ) , tomcat doesnt throw error saying this class is not found. But When I change the host name to soemthing else ( for eg , an IP address that is referenced by DNS , ) tomcat throws the error about the class not being found. So, my questions was what is the difference between host name as localhost and host name as something else , that makes tomcat recognise this class as not being present Thanks, Anand On Mon, Dec 1, 2008 at 5:42 PM, Caldarale, Charles R < [EMAIL PROTECTED]> wrote: > > From: Anand HS [mailto:[EMAIL PROTECTED] > > Subject: Re: What exactly happens when I configure a different host > > > > java.lang.ClassNotFoundException: > > com.psi.servlet.Log4jInitializerServlet > > So where is the class file for com.psi.servlet.Log4jInitializerServlet > located? > > - Chuck > > > THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY > MATERIAL and is thus for use only by the intended recipient.

Re: What exactly happens when I configure a different host
I did these steps - 1. Renamed admin-web to ROOT. 2. made sure to delete existing ROOT folder that comes bundled with tomcat. 3. Added context.xml to webapps/ROOT/META-INF with contents being 4.

What exactly happens when I configure a different host
Hi, I am trying to deploy a simple war file into a freshly downloaded tomcat 6.0.18. I noticed a strange behavior when I tried to configure a virtual host by changing the Host Name in server.xml from the default "localhost" to " mydomain.com". The strange behavior goes like this 1. the web.xml inside my war has a servlet defined which is not presnet in the war file or any of the libraries tomcat loads. 2. With the default host name as localhost, tomcat does not thrown any "ClassNotFound" exception for not finding this missing servlet. 3. If i change the host name, tomcat throws a nice java.lang.ClassNotFoundException: com.psi.servlet.Log4jInitializerServlet at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1387) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1233) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1094) at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:992) ( Log4jInitializerServlet is my servlet which is missing ). I can get rid of this error by removing the servlet inclusion block though. Can any one tell me why the localhost as Host name ignores this error. ? I can provide more details if wanted. Thanks, Anand
