Jcorporate Ltd. is pleased to announce the availability of Expresso, an
application development framework, version 3.0 for download.
To download the new release, go to the Expressso project page:
http://www.jcorporate.com/components/internal/projframe.jsp?category=65 And
select the download link.
There are two .war file downloads for Expresso available: the
"expresso3-00.war" file contains object-code only, and no documentation or
Javadoc, and is intended to be convenient for use with a binary installation
of other applications, such as eForum, ePoll, etc, or with your own
application deployments. The other .war file, "expresso3-00-src.war"
contains the full source and binaries, along with complete documentation and
Javadoc.
Expresso provides standard web application functionality such as
configuration management, security, Object-relational mapping, database
connection pooling, email connectivity, job control, logging, event
notification, caching, internationalization, automatic form generation for
database maintenance, Expresso XML, and new new JSP tag library for
accelerating GUI development. Expresso enables developers to decrease their
learning curve and time to solution, which translates directly into reduced
costs and increased revenue for customers.
What's new in 3.00?
-------------------
Version 3.00 of Expresso introduces the following enhancements:

introduction of a utility to upgrade existing applications.
* Enhanced deployment in Application Server contexts using the Web
Application Archive format, facilitating multiple applications deployed in a
single context.
* Enhanced Security with optional strong encryption of any data.
* Integration with the Apache Log4j logging sub-system, enabling rapid
analysis and debugging of applications.

parser and Xalan XSL transformation tool for XSL support and complete UI
independance.
* Enhancements and extensions to the powerful "Controller" package,
enabling full separation of the model, view and controller and enhancing
application extensibility and maintanance.

error handling, including customizable display of errors to the user,
logging, and emailing of error notifications to selected administrators
(complete with stack traces as required).

XP (Extreme Programming) development model with full unit tests of each
component as it is created, ehnancing application reliability.

allowing sophisticated form-based maintenance of any database table.
* The ability to associate specific database objects with a particular
database/context, facilitating cross-database and multi-database
applications, such as data warehousing.

lanaguage files and local formats for data & numeric data.
* Many enhancements to performance and efficiency.
* Hundreds of other small bug fixes and enhancements to existing Expresso
functionality.
