I just did a clean/reinstall as you suggested (using the default configuration),
and now the pluto portal driver service seems to start OK.  I did have to remove
a couple of old directories (pluto, testsuite, IIRC) in the Tomcat webapps
directory to get this much to work.

But I almost immediately run into a new problem:  as soon as I browse to the
portal (http://localhost:8080/pluto/portal/), the system asks me to log in --
this wasn't required previously, and I don't really want to deal with this in my
test environment.  I'm guessing it requires a legitimate Tomcat user:  In tried
a random credential and was immediately told it was invalid, so I tried the
Tomcat admin user details and was rewarded with a 403 access denied page.

Also, about this time, I tried the back button and/or fiddling with the URI and
got a null pointer error displayed in my browser.  I forget exactly what I did,
and the system seems to be keeping some login state so I can't reproduce the
problem, but I do attach the Tomcat stdout/stderr logs covering that event;  the
error reported in the log is not exactly the same as that on the browser
display, but that may be because the browser display was truncated.

I had made a couple of minor changes to the Pluto source code to generate some
additional diagnostic information: I'll try reverting those to see if it makes
any difference ... no difference at all, and now I have the exact sequence used:

1. Start Tomcat
2. Browse to http://localhost:8080/pluto/portal/
3. Give bad credentials
4. Give Tomcat admin credentials (per $CATALINA_HOME/conf/tomcat-users.xml)
5. Pluto displays access denited
6. Press browser back button -- previously entered admin credentials are displayed
7. Click "Login" button to (re)enter same credentials
8. Pluto displays null pointer error:
[[

...

I just noticed that the system is updating my system disk root directory ...
it's creating a directory C:\.pluto on my Windows system, which is, er, a little
rude of it ;).  It's pick an inappropriate directory here -- is there a config
option to force an override?  Better still, is there a (tested) config to just
read details from a file, or even just include the required details in the
config file itself?

This is illustrative of the complications I wanted to avoid.

...

Other minutiae:

(a) The login screen is displaying the password entered as clear text.

(b) I'm seeing a couple of warnings from the 'mvn install' like this:
[[

local scope.

]]

There's a similar one referring to junit in another module.

I'm assuming this isn't indicative of any problem.

...

I shall be out of circulation (except for occasional email) for the next couple
of weeks, and then I really need to move on to other parts of this project, so I
 don't know when I'll be fully engaged again with this strand of activity.
