It's my understanding that processRequest() should init the Bean ( in addition
or instead of just setting properties). That mean the "semantic" of processRequest()
is more "initBean" ( you can do more - but I don't think it's a good ideea to
take any action - since you want all the beans in the page to be initialized before
starting any action, maybe other beans "processRequest" have something to do and
you'ld brake it).
The problem is that there is no second method called after all init is done and
before getting the response stream.
A similar problem - you might want your bean to have access to ServletContext,
so you can use Log for example. We solved this problem by changing GNUJsp (
the other one can be solved in the same way, we avoided it )
I hope 1.0 will solve both problems.

That may be a bad ideea.
I use generic beans ( the same I use in a Swing application), and when I realy need
processRequest I extend them with this method ( processRequest can be avoided
in most cases ).
The servlet is not a very good abstraction to design with ( i.e. it is less powerfull
than
a Bean - no introspection, etc). And also, it is hard to reuse it - that's why it's
better
to use it just as an adapter between your code and the web server, and to not put too
much code in the adapter.
