I may really be missing something here, but my impression was that a host's default web application is used whenever a URL is requested that does not match any other context's path prefix within the host - regardless of the access being made by IP address or by domain name. To me, this means that I *need* a default context if I want to see the welcome page of my "foo" web application (within the host named "www.foodomain.com") at "http://www.foodomain.com"; and not at "http://www.foodomain.com/foo";, right? If this is right, then I'd have to tamper with server.xml or name my .war file "ROOT.war". I can live with the latter, but it feels somewhat unclean. IMO, the same applies to setting up a minimal ROOT.war that simply forwards to another context, since this will also cause an unnecessary /foo prefix in every subsequent request URL. -- Thomas Corte <[EMAIL PROTECTED]> - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: "No Host matches server name localhost" error
First, let me clarify that I am only a user of Tomcat and was simply pointing out the part of the documentation. Now as for the issue, I am not sure that it is a bug but just a feature. Unless you can show where it does not meet the servlet specs then it will not be considered a bug. I am not sure why this is causing such a problem. The only time a default context will ever be used is if the browser is using an IP instead of a URL or if you have a DNS entry that points to your IP with no matching application. So unless you are using only the IP or are directing multiple unmatched URLs at the server there is no issue. If you are, then knowing what the war is about is only a small piece of the puzzle that exist in the setup. Just my understanding of the setup. Feel free to enlighten me if you think I am off base. Every aspect of a program is considered a feature. No matter how good or bad one may think it is. It only become a bug when it breaks a rule. Either the programmers rule, a system rule or a specification rule. If a feature that was considered bad by some could be classed as a bug, then 90% of the code written in the world would be bugs because somewhere there is someone who doesn't like it.

I believe the usual mechanism for handling this is a trivial ROOT webapp that forwards to the true default application. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

As far as I know, you can - just put your default context in webapps/ROOT, and its associated element in webapps/ROOT/META-INF/context.xml. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: "No Host matches server name localhost" error
The error your getting is more likely saying that you computer can not resolve localhost as domain name. If so it would have nothing to do with your server config. Try using the loop back IP(127.0.0.1). If this is happening on a windows box you may want to run a check for viruses or spyware. If it is Linux make sure you have a listing for localhost in your /etc/hosts file.

Re: "No Host matches server name localhost" error
Try renaming the context.xml to ROOT.xml, I normally get the 400 error if it can't find the context for a particular path. For some reason Tomcat tends to ignore the path on the context.
