jUDO (java Universal Data Objects) speeds up development/maintainence and removes database-vendor dependency for applications using databases. You should use jUDO whenever you don't want to use EJBs. You don't write any database code; you only have to specify the container classes and the interfaces for the models, and then jUDO creates the implementation for you runtime (no source is generated). It derives all info needed from your interfaces method names that follows name-pattern rules. In case you need some special access method, you either add a plugin for this or simply go directly against the database. jUDO is not as configurable and advanced as other much more professional software like Castor, Hibernate, etc., but since jUDO derives the database from your code, there is never a mismatch between code and database.
DBMonster is a tool which helps database application developers with tuning the structure of the database, tuning the usage of indexes, and testing the application performance under heavy database load. DBMonster generates as much random data as you wish and puts it into an SQL database. It provides a very pluggable interface and is trivial to use.
Furies is a Java-based Web site testing tool which relies on many Jakarta components. Its goal is to ensure a Web page is "correct" by running one or more conditions on it. The Furies distribution supplies some conditions and it is very easy to program your own. For accessing Web sites, Furies relies on HttpClient and configuration may be done programmatically or via Digester.
b-frame is a framework for rapid J2EE development. It is based on the assumption that it is possible to create business (i.e. transactional client server) applications just from knowing their structure. It defines sets of XML tags for describing databases and applications operating on these databases (application layer) and template implementations (implementation layer), respectively. It provides XSLT-stylesheets (core layer) for merging the user provided application layer and the template layer into real applications. By default, it comes with a J2EE implementation layer.
MaXPI is a Plug-in for Jakarta Turbine Maven that adds some goals to help Mozilla Application Developers handle daily development tasks more easily. They can create ready-to-code Mozilla Application Directory Layouts based on a POM configuration and easily build Mozilla applications as source and install packages.
Anteater is a testing framework designed around Ant, from the Apache Jakarta Project. It provides an easy way to write tests for checking the functionality of a Web application or of an XML Web service. It can test either HTTP requests or replies in various sophisticated ways. The ability to wait for incoming HTTP messages is unique to Anteater, which makes it especially useful when building tests for applications that use high level SOAP-based communication and asynchronous SOAP messages. Anteater provides XML and text logging support and the ability to render the logs into HTML reports.
mod_epp is an Apache 2.0 module that implements the EPP over TCP protocol as defined in draft-ietf-provreg-epp-tcp-06.txt and the session management parts of draft-ietf-provreg-epp-0(6|7|8).txt. This is not a full implementation of EPP; this module just makes it possible to write an EPP server as a set of CGI scripts.
