I have been using Expresso for a year or so, mostly because of my twisted view
of an applications as being a database with views attached - Expresso is very
database oriented. For example, getters and setters instead of SQL sequences,
as well as the flexibility of changing databases rather casually.
I am only in the last few months growing to understand the tremendous benefits
of MVC and Struts, and am glad to see the complete integration of Struts into
Expresso, so now I can have both as become MVC based.
I would also suggest that one of the most overlooked benefits of Expresso is
middle tier data caching. When your boxes don't have to go back to the database
for every data query, it can really cut down on the traffic to the DB and
potentially more speed. The promise of java, fullfilled, to my perception.
Struts is not the only Apache project woven into Expresso - Log4j, Junit,
Regexp, Xalan, Xerces and I think others? So far, anyway, the core group seems
much more interested in working to accepted standards than re-inventing wheels.
Last but not least, Expresso has a code wizard that you can use on line for
free, which writes the basic application structure - jsps, dbobjects and
controllers, also with custom registration and login views, so you can just feed
it a database schema and concentrate all your efforts on the business logic and
navigation. Unfortunately, it hasn't been converted to Struts yet, so I would
not recommend the wizard until that happens.
