Ok, it is a bit disappointing that Tomcat does not support this in
standard webapps folder.
But I found an easy workaround: create Windows junction app#latest
that points to app#1 folder (both in webapps).
You are doing something which is definitely not recommended. Expanding
your WAR file twice on the disk really shouldn't be a big deal. I would
challenge your requirement for having a single directory for these two
contexts. There is no memory savings whatsoever by doing this. You only
save disk space and perhaps the time-to-expand the WAR file (which is
done only once per deployment).

L21ZaJtvg%3D&reserved=0 it is not clear to me how to achieve
the following:
Have one WAR file with corresponding directory, for example:
app#1.war => app#1 (directory) => /app/1 (context path)
But have another context path pointing to same application:
/app/latest (context path) => app#1 (directory)
I tried adding <Context> to server.xml inside <Host> like:
<Context docBase="app#1 " path="/app/latest"/>
But Tomcat created another directory app#latest from this, and
copied app#1 there. I would like to avoid having duplicate
directories.
Doc says that: * To define multiple contexts that use a single WAR
file or directory, use one of the options described in the Naming
section above for creating a Context that has a path that is not
related to the base file name. * If you want to deploy a WAR file
or a directory using a context path that is not related to the base
file name then one of the following options must be used to prevent
double-deployment: ** Disable autoDeploy and deployOnStartup and
define all Contexts in server.xml ** Locate the WAR and/or
directory outside of the Host's appBase and use a context.xml file
with a docBase attribute to define it.
Don't quite understand what to do. Do I need add <Context> also to
the existing application:
<Context docBase="app#1 " path="/app/1"/>
Or what does "define all Contexts in server.xml" mean? And what
does the second option (Locate the WAR...) mean?
The key part is you need to locate the docBase (the web application
WAR or directory) NOT under the appBase ($CATALINA_BASE/webapps). So
something like this:
/opt/webapps/myapp-1
and then under $CATALINA_BASE/conf/Catlaina/localhost you'll need two
context files:
myapp#1.xml <Context docBase="/opt/webapps/myapp-1" />
myapp#latest.xml <Context docBase="/opt/webapps/myapp-1" />
