Specify context path when context.xml is in META-INF
Is there a way, when you have your context.xml in META-INF rather than
specifying the Context element in server.xml or elsewhere, to customize the
context path?
I'd like to use context.xml in META-INF because of the benefits of this
approach, but there seems to be no way to change the context path, which is
always the name of the folder underneath appBase. For example, if appBase
contains a folder called webroot, then the context will be called webroot.
(It's not possible to change the name of this folder for some internal
reasons.)
The documentation seems to indicate that a path attribute cannot be present
in the Context element when context.xml is in META-INF - is there another
way to achieve the effect I've described? If not, is there a strong reason
why context.xml in META-INF couldn't read and use the path attribute of
Context?
Thanks.

Correct; doing so requires a Tomcat restart to change anything, and goes
against the servlet spec premise of webapps being self-contained.

If the webapp requires no customization for each deployment, then
keeping the <Context> element in META-INF/context.xml has the distinct
advantage of having only one entity (the .war file) to deal with.
However, if customization is required, then distributing the <Context>
element separately for placement in conf/Catalina/[host]/[appname].xml
makes it easier on the sysadmin. The latter approach avoids having to
take the .war file apart manually, update the <Context>, and put it back
together.

Based on what I've read, I've learned that the least ideal approach is to
place the context information in server.xml.
What I don't know, though, is how the remaining options stack up to each
other. What are the tradeoffs (apart from the path naming issue) of placing
context.xml in META-INF versus as conf/Catalina/[host]/[appname].xml? For
what reasons is one approach better than the other?
I don't have as much experience deploying to Tomcat as some of you might, so
I'm hoping you could outline the advantages and disadvantages of either
approach.

No - the path is taken from the name of the .war file or directory. The
only way to accomplish what you want is to place the <Context> element
in the conf/Catalina/[host]/[appname].xml location, in which case the
[appname] is the path. The application should not be placed in the
<Host> appBase in this case, or you risk double deployment.

Primarily to avoid ambiguities and extra, unwanted deployments.
