Setting form properties against beans is a Struts thing, not a JSP
thing. The property thing is a Bean thin and can be looked up in the
JavaBean spec.
The example you quote...
"monkeyTeamAlpha.monkeyWorkers[0].salary"
...is a nested property. An invention implemented within Struts
(Craig?). What it basically is, is a string of calls rather than the
single property method. Here, it will get a hold of the form bean, get a
hold of the bean returned from the "monkeyTeamAlpha"property. On this
bean, it will invoke the indexed property "monkeyWorkers[0]" which will
pluck a bean from a collection or index provided, from this last bean it
will will get a hold of its "salary" property, and set the value.
All this boils down to, is that you can compose objects a little
cleaner, rather than have truly enormous beans for everything. Having
the indexed properties allows for lists and whatever else.
The ability for nesting beans has been in Struts for a long time. The
nested tags just make it much easier.
There's a primer and tutorial for nested beans here...

...it should take you over creating and using such a construct.
Hope this gets you on th path you're after.
