Thanks Gustav,

What I was confused about was that I could see that the new tree would
need to be served under a different URL, and I was unclear as to how
that happened. When I looked at your installwin.html, I noticed that
the directory name appeared in the URL. So then I had a look at
AutoConf.mpl and when it sets TomcatContext it first checks if the
subdirectory of webapps containing the AiM stuff is ROOT or something
else. If it's not ROOT then the directory name is appended to the URL.

So, now I have my parallel developer's AIM directory at:

  http://olld.maths.curtin.edu.au/AIM/

and my original which was in webapps/ROOT under

  http://olld.maths.curtin.edu.au/

... and it all works fine, except that you will notice that I didn't
want port 8080 (but instead use port 80) which I have configured in
ManualConfig.mpl. However, everytime the admin.html and index.html
page are regenerated (by adding a subject) the form action is set
to a URL with :8080 inserted. I can edit it correctly by hand, but
where is this coming from? It's apparently generated by aim/Zone.mpl
using Config['ServletURL'], but I've checked this via Console.mpl
... it is the URL given above. So what's going on?

PS I had to make a few adjustments to AutoConf.mpl and Servlet.mpl
to repair things for Linux and fix typos.

BTW It was a nice idea to make AutoConf.mpl proceed on to reading
Servlet.mpl and Make.mpl. That simplifies the install quite a bit
for first time users.

[Aimmath-developers] port 8080

This is strange. If you have set Config['TomcatPort'] = "80" in your
ManualConfig.mpl then there is really no way the 8080 could enter. The only
place where 8080 is explicitly in the code is in AutoConf.mpl in the
following line:

  setconfig('TomcatPort' , "8080"):

But the way setconfig works is that if TomcatPort is already assigned a
value then it is not overwritten. So it should still be 80.

The only idea I have is that perhaps you first used your installation on
port 8080 and later changed to 80. It is then possible that the 8080 has
found its way into some of the automatically generated files in the
directory web-inf/root. Could you search all files in there for an occurence
of 8080?

Indeed, I had neglected to add the configuration 

Config['TomcatPort'] := 80:

in ManualConfig.mpl, on my first pass and so the file DefaultZone.mpl 
written to the top of the WEB-INF/root directory had the port :8080
inserted in the servlet URLs.

I see that this file is first written by AliceServer.mpl. I would have
avoided the problem if I had removed this file before rereading
AutoConf.mpl. We should have a warning that WEB-INF/root/DefaultZone.mpl 
should be removed or at least checked for wrong information before
re-reading AutoConf.mpl after changing ManualConfig.mpl in our 
installation instructions.
