So I've created the above class and loaded it from the class loader page,
ie. "java:magi.Counter" and that brings me to the following page:

https://waterken.naasking.homeip.net/wwwsandro/?key=3Dnsrd-wduu-6qll

On this page is a link to "
https://waterken.naasking.homeip.net/http/localhost/magi/Counter-class"
(which resolves to a 404), and a "new" link (which I presume is a link to
the constructor).

Clicking on "new" brings me to a page with "
http://localhost/magi/Counter-class-new<https://waterken.naasking.homeip.ne=
t/http/localhost/magi/Counter-class-new>"
and a single submit button. I presume this is the interface to invoke the
constructor.

Clicking "submit" does not appear to create any new objects on the
filesystem, though a new transient Counter appears to be created with the
appropriate 'current' value of 0.

However no additional 'permanent' object appears to be created, nor can I
invoke the "add" method on this instance. Does this object need to be
explicitly inserted into the database for any further operations?
