Thanks for the help Oliver.  This was a much more time-consuming task with
Maven than I had was expecting.  We had Jasper errors trying to run the
subsequent WAR on WebLogic, forcing us to revert the tasks to a more manual
process.

For my goal of (1) precompiling the JSPs and (2) removing the JSPs from the
WAR (just keeping the compiled Java classes of those JSPs there), the
problems I came across were:

1.)  The documentation[1] appears to indicate that we can use <exclude/> to
pull out files from the WAR (i.e., those JSPs we no longer need after we
compile them), but numerous attempts to use <excludes/> failed.  Apparently
Maven is redundantly retaining both an <exclude/> and <warSourceExcludes/>
mechanism, or, if they have deprecated the former, need to update its
documentation to indicate that.

2.)  The <warSourceExcludes/> is removing the JSP's *before* they are
compiled into Java classes, so I end up not getting either the JSPs (good)
nor the compiled Java classes (bad) in the WAR file.  There needs to be some
setting to this for me to request that the JSPs be removed *after* they are
compiled.

3.)  The Jasper error we were getting on weblogic might have been because we
did not specify the "jspc-compiler-tomcat5" option as you did below. 
(Another team member reverted this method without knowing to test this.) 
I'll need to see if this was indeed the problem we were having on Weblogic,
and if so, to submit a bug report/patch to have the Maven docs updated with
the Tomcat compiler info you list below.

Regards,
Glen
