Tomcat-6.0.6 - path attribute not honored in Context descriptor files.
Problem:
The "path" attribute in the Context descriptor file no used in
TC 5.5 and 6.0.
Background:
In an application deployment you whish to be able to install and
upgrade both tomcat and your WARS individually. In TC 4.1 this was
easily done by dropping a Context descriptor file in the webapps
directory. This Context descriptor contained beside local
configurations mainly what was deployed (docBase - which WAR) and where
it should be deployed (path - mount point for the WAR). Name of the
Context descriptor file was arbitrary except it had an '.xml'
extension.
The ability to drop Context descriptor files are now moved to the
$CATALINA_HOME/conf/[enginename]/[hostname] directory OK. The problem
is that the "path" attribute is ignored in the Context read from this
directory. Only Contexts defined in the server.xml file honors the
path attribute. Defining the Contexts in the server.xml file is though
discouraged of obvious reasons.

If you think the way Tomcat handles deployment is wrong, OK. But I don't think
you convince the developers (I'm not one, BTW) to change their point of view
by hijacking a thread and posting a "problem" report.

1. I don't know whether this mechanism is supposed to be portable (in fact, I
strongly doubt it). If you think it violates the specs, you should quote the
correspondig passage which says it has to be done otherwise.
2. It's documented. I even quoted the relevant part of the documentation in my
previous post.

You could file an enhancement request in bugzilla.
Or, you could search the list archives. I'd consider it possible that you find
some explanation why the devs decided to change the way how the app-path is
set.

I know that it works according to the documentation but I can't
ignore the fact that I believe it's wrong. If you look closer in
the code of HostConfig.deployDescriptors() you note that others has
missed the ability to set the context path and has hidden it in the
filename which is neither portable nor documented.
File contextXml = new File(configBase, files[i]);
if (files[i].toLowerCase().endsWith(".xml")) {
// Calculate the context path and make sure it is unique
String nameTmp = files[i].substring(0, files[i].length() - 4);
String contextPath = "/" + nameTmp.replace('#', '/');
if (nameTmp.equals("ROOT")) {
contextPath = "";
}
If you understand me I believe it's a mistake to tie the Context
descriptors file name to the context path while there is a clean and
documented way of defining the path in the context tag. In this aspect
I believe the way it worked in TC-4.1 is to prefer and I ask you
to reconsider it.

That's not a problem. It's exactly the way it's meant to be:
http://tomcat.apache.org/tomcat-6.0-doc/config/context.html
