webapp.root to webapp.dir

[Eddie O'Neil <ek...@bea.com>]

All--

   There's a bit of a naming problem for a property that is expected by 
the runTomcatCore.xml and buildWebappCore.xml files.

   The former requires "webapp.root" to refer to the directory that 
contains the exploded WAR.  The latter requires "webapp.dir" to refer to 
the same directory.

   I'd like to change these names to be a consistent "webapp.dir".  The 
result is that anyone that has local build files that pass "webapp.root" 
to the Tomcat "deploy" target will be broken.

   Assuming everyone is okay with this, I'll apply this change to all of 
the callers that are in the SVN tree.

   Apologies for any inconvenience!  Please let me know ASAP if anyone 
has an issue with this.

   Thanks!

Eddie
