Is the DNS name mysvn defined on the machine your browser is running on? Internet Explorer could not display this web page i test this in local machine, so i do not use a DNS. mtail, The gurus here are flying high, and a bit intimidating sometimes. So allow me to try, since for once I can maybe be useful here. It is not enough to define a virtual host in Tomcat. Your browser must also know where that virtual host is (on which machine). Even if this all happens on one single machine, the browser does not know who mysvn is, unless you give him a way to find out. So let's start at the beginning. 1) When you type in your browser a URL like http://mysvn:8080/something.html the first thing the browser has to do, is to find an IP address that corresponds to the hostname mysvn. That is because, on the Internet, machines find one another via IP addresses (like 123.23.34.102), and not by names (like mysvn). Names are only something for humans, easier to remember than numbers. 2) There are 2 places where the browser can find a translation of a host name into a host IP address, and it will try them in this order : (a) : in the local hosts file. Under Windows, it is usually c:/windows/system32/drivers/etc/hosts and under Unix, it is usually /etc/hosts (b) : using the DNS system. That means, the browser knows the IP address of a DNS server, which is another computer which has access to a long list of translations between host names and host IP addresses, and it will ask that server. So, the browser will first try (a). If the browser is looking for the IP address of mysvn, and if there is a line in (a) like 1.2.3.4 mysvn then the browser is happy : it now knows that the server IP address of mysvn is 1.2.3.4, and it can stop looking. If the browser does not find a translation in (a), then it will ask (b) (the DNS system) for a translation. If the DNS system also does not know, then it will send back I don't know, and your browser will say Cannot display that page, because it cannot even find the IP address of the server to which it should be talking. 3) When the browser has obtained a translation for mysvn into an IP address, then (and only then) it can go one step further : It can now compose a HTTP request and send it to that IP address 1.2.3.4. This HTTP request will look like this : GET /something.html HTTP/1.1 The browser will also add a second line to that request, like Host: mysvn 4) If all the above happened correctly, then the Tomcat listening at the IP address 1.2.3.4 will receive the request from the browser. It is very important that you understand this : Tomcat only receives the request if the browser has sent it to the correct IP address of the host where the Tomcat server runs. That is true even if this all happens on one single machine. If your browser could not get an IP address for mysvn, or if it got the wrong one, then Tomcat never even sees the request. 5) But let's suppose that everything above went fine, and that Tomcat receives the request. Tomcat now looks at the second line of the request, the one that says : Host: mysvn That is when the Tomcat virtual hosts come into play (but not before). Tomcat will now look if it has a Host named mysvn. If it has one, it will use that Host configuration to answer the request. (If Tomcat has no such Host, then it will use its default host to answer the request anyway.) 6) Now there can still be an error : If the browser asked for the page /something.html, and Tomcat does not find that page in the document area of that virtual Host, then Tomcat will return an error not found to the browser, and the browser will also say Cannot display that page. But the point is, this is another kind of error, and it happens later. Your problem is probably due to the first reason : your browser cannot even find an IP address for the server mysvn. It cannot find it, because it looks first in your local hosts file, and there is no line there with mysvn. Then it asks the DNS system, and the DNS system also does not know the IP address of mysvn. On the other hand, when your browser tries to find the address of localhost, then it *does* find it in the local hosts file, and that is why your URL http://localhost:8080 works fine. -- note -- The IP address 127.0.0.1 is special : it always means this machine. So if you do ping 127.0.0.1 on any computer, that computer will always ping itself. Or if you ask your browser http://127.0.0.1 the browser will try

Hi, I deployed my webapp svn.war on webapps directory of tomcat 6. I configured localy a virtual host with tomcat 6, but it does not work. This url works : http://localhost:8080/svn/ But when i use the virtual host, it does not works : http://mysvn:8080/ This is a part of server.xml : ...

Re: tomcat virtual host
I agree with the other response: rename your war to ROOT.war, so that it is the root web application. By the way, it is worth changing only one thing at once in your URL when testing. You are changing two. Does http://localhost:8080/ work? Does http://mysvn:8080/svnrepository work? But if i do this, how can i access de tomcat manager ? with other name, but the examples will work ? - 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: tomcat virtual host
Sorry, but your question does not make any sense to me. I don't see anything stopping you from adding as many virtual hosts as you want. If you need a different default webapp for each virtual host, then each Host will have to specify a different appBase attribute. Any webapps that you want to be visible on multiple virtual hosts will either need to be deployed under each appBase, or have a Context element in conf/Catalina/[host]/[appName].xml that provides a docBase attribute pointing to the location of the webapp. - Chuck I configured localy a virtual host with tomcat 6 This url works : http://localhost:8080/svn/ But when i use the virtual host, it does not works : http://mysvn:8080/ Find file attached server.xml please : Thank's ?xml version='1.0' encoding='utf-8'? !-- Licensed to the Apache Software Foundation (ASF) under one or more contributor license agreements.
