Thanks for the input regarding 2). What's the difference between using

Also, do you know the answer to 1 - ie, why did the change occur regarding
not exploding when the WAR is outside appBase?
Please don't top post. I just switched to using a real mail client and I
now know why others lament so much about this.
Anyway, from the fine documentation at:
http://tomcat.apache.org/tomcat-7.0-doc/config/context.html
workDir
Pathname to a scratch directory to be provided by this Context for
temporary read-write use by servlets within the associated web
application. This directory will be made visible to servlets in the web
application by a servlet context attribute (of type java.io.File) named
javax.servlet.context.tempdir as described in the Servlet Specification.
If not specified, a suitable directory underneath $CATALINA_BASE/work
will be provided.
So in short, read the Servlet Specification. (This is also of type File,
while the property is of type String.)
I suspect that if you use javax.servlet.context.tempdir, the scratch
space will be under CATALINA_BASE/work/[Engine]/[host]/[app].
[Engine] is by default Catalina
[host] is by default localhost
[app] is your web application context name
This is different than java.io.tmpdir, which is set to CATALINA_BASE/temp.
One of the nice things about using javax.servlet.context.tempdir is that
it's deleted when you undeploy your application.
Another nice thing about javax.servlet.context.tempdir is that you get a
location per web application, not a location per Tomcat. This means that
various contexts can't step on each other.
One of the not so nice things about javax.servlet.context.tempdir is
that it normally doesn't exist outside of a servlet container or web
application server. This means that if you do unit testing, you'll have
to define that property when you run tests with
-Djavax.servlet.context.tempdir="somewhere-i-can-write" and open this as
a file (see above for comments about type).
For your answer to question 1, I guess you'll have to read any
discussion on the development mailing list. Searchable archives are
available online. I'm just a user, and while I casually read the
development list I don't currently don't participate.
. . . just my 2 cents.
