Addons are *built* against the code the add onto, so won't this happen
at build time? At install time they just drop in, if properly
organized. We can document the meaning of "properly organized".

Eww. I *hate* finding there's a whole web server inside some thing I
wanted to plug into the web server that I already had running. While
an all-inclusive package may appeal to some, I would choose another
packaging.

This part is ridiculously simple in Tomcat:
$ cat /etc/tomcat-6/Catalina/localhost/mhw#trunk-1.7#xmlui.xml
<Context
docBase='/home/mwood/dspaces/trunk-1.7/webapps/xmlui'>
<Parameter
description='Path to the DSpace configuration file.'
override='false'
name='dspace-config'
value='/home/mwood/dspaces/trunk-1.7/config/dspace.cfg'
/>
<Resource
name='jdbc/dspace'
description="DBMS connection pool for DSpace's database"
type='javax.sql.DataSource'
factory='org.apache.commons.dbcp.BasicDataSourceFactory'
auth='Container'
username='foo'
password='baz'
driverClassName='org.postgresql.Driver'
url='jdbc:postgresql://localhost:5432/mhw-trunk-1.7'
maxActive='30'
maxIdle='-1'
maxWait='5000'
/>
</Context>
The above is running right now (except that those aren't the real DBMS
credentials). It provides everything DSpace needs to know to find itself.
Okay, it doesn't *look* simple, but most of it is boilerplate. A
path, two class names, a database name, a user name, and a password
are all that need vary until you know your way around the product.
Tell the installer program which DBMS you use and it supplies the
class names, which are the only bits you might not know.
Drop one of those where Catalina looks for them, and it starts.
'touch' it and the app. restarts.
