I've been using Tomcat 6 and 7 for a while, and now running Tomcat 8.
it is recommended that <Context> elements not be placed directly in
server.xml
I know, but it is much easier for me to edit a single file, server.xml
then deploy all the other files. I'm looking to keep the deployment
process as simple as possible.
you shouldn't need the empty directory. I've used an absolute path
for the <Host> appBase attribute with relative paths for <Context>
docBase attributes in Tomcat 6 and 7 without any problems.
when I try that then "webapps" is used by default. if a request is
made for a file that exists in webapps, e.g. index.jsp and does not
exist in my application's folder, then it is served from webapps and I
don't want that.
are you sure you want "/" for the <Context> path attribute in the
first example above?
it was my understanding that "" and "/" are the same here. "/" reads
more clearly to me as the "root" directory so I prefer to use that.
*after reading your email and testing it, however, I noticed that if I
omit the Host/appBase and use an empty-string for the
Context/docBase/path it works as intended, so maybe that's what I was
doing wrong? is that the best practice?*
<Host name="Site1" unpackWARs="false" autoDeploy="false">
<Context path="" docBase="D:/www/site1" />
<Context path="/virtualdir" docBase="D:/www/shared/virtualdir" />
</Host>
?
thank you both for your responses,
Igal

I'm a little confused about the Host appBase attribute.
Let's say that my website resides in D:\www\site1
I don't like using {Tomcat}/webapps so I don't want to have it as a
base directory for websites. What I've been doing so far is create
an empty folder alongside "webapps", named "empty", and use it as
appBase, e.g.
<Host name="Site1" appBase="empty" unpackWARs="false"
autoDeploy="false">
<!-- this works but what's the deal with appBase? !-->
<Context path="/" docBase="D:/www/site1" />
</Host>
But it feels like I'm doing something wrong. I expect this to work,
but it doesn't:
<Host name="Site1" appBase="D:/www/site1" unpackWARs="false"
autoDeploy="false">
<!-- this doesn't work !-->
</Host>
Can anyone explain why the snippet above doesn't work, and if that
is the way it should be, then what is the purpose of Host/appBase?
TIA
Hi, Igal-
What version of Tomcat are you using? Also, it is recommended that
<Context> elements not be placed directly in server.xml. See:
http://tomcat.apache.org/tomcat-7.0-doc/config/context.html#Defining_a_context
That said, you shouldn't need the empty directory. I've used an
absolute path for the <Host> appBase attribute with relative paths
for <Context> docBase attributes in Tomcat 6 and 7 without any
problems. I haven't tried it with absolute paths for both appBase
and docBase.
Lastly, are you sure you want "/" for the <Context> path attribute in
the first example above? The <Context> path for the default web
application of a <Host> should be an empty string (""). See:
http://tomcat.apache.org/tomcat-7.0-doc/config/context.html#Common_Attributes

Hi, Igal-
Glad you were able to get it working. Please note the warning in the
Tomcat docs about using the Context path attribute that reads:
"Even when statically defining a Context in server.xml, this attribute
must not be set unless either the docBase is not located under the
Host's appBase or both deployOnStartup and autoDeploy are false. If this
rule is not followed, double deployment is likely to result."
This is included in:
http://tomcat.apache.org/tomcat-8.0-doc/config/context.html#Common_Attributes
For information about about how context paths relate to WAR file names
and application directory names, see:
http://tomcat.apache.org/tomcat-8.0-doc/config/context.html#Naming
In particular, please note that "If the context path is the empty string
them the base name will be ROOT (always in upper case)...".
The recommended practice is to create separate context XML files and
package them in the application WAR files. However, for simple
installations, I've had success with something like:
<Host name="Host"
appBase="c:/webapps"
autoDeploy="false"
deployOnStartup="true"
unpackWARs="true">
<Context path="" docBase="ROOT" />
</Host>
The [Tomcat]/webapps directory may then be deleted (if you don't need
the packaged apps or doc) and ROOT.war placed directly in c:/webapps.
