1. The file default.cfg contains
server.webapp.examples.mapping=/examples
server.webapp.examples.docbase=examples
2. Yet the URL for the examples is
http://localhost:8080/examples/servlet/HelloWorldExample
3. and the actual location is
/jsdk2.1/examples/web-inf/servlets/
I don't see how this works out. How do facts 1 and 3 result in 2?
How does the servletrunner know where to look?
How can I add my own paths? Or can I?

Servlets are either in context/path/WEB-INF/servlets (where they're by
default accessed as /context/path/servlet/Foo) or they're in the
server's classpath. If you look, the classpath set by the startup
script includes jsdk2.1/classes, but you can change that within the
startup script.
In default.cfg you can see how contexts are added. Contexts can be
dirs or even other sites. How's this one for cool:
server.app.proxy.mapping=/proxy
server.app.proxy.base=http://otherserver/
Now http://localhost:8080/proxy/index.html serves
http://otherserver/index.html. Fun, cool, and even potentially useful
when you have a client with limited network visibility.
I think the API 2.1 getResource() abstraction facilitated this.
For more fun, picture if you write a new protocol handler what you
could do here.
server.app.db.mapping=/db
server.app.db.base=dbtp://something
Assuming you wrote a protocol handler for the "database transfer
protocol", you could as easy as this serve files coming from a db.
Exactly how URIs mapped to db queries would be known by the dbtp
handler.
