The DBacesslayer (or DBSlayer for short) is a lightweight database abstraction layer suitable for high-load Web sites where you need the scalable advantages of connection pooling. DBSlayer talks to clients via JSON over HTTP, meaning it's simple to monitor and can swiftly interoperate with any Web framework you choose.
JCatapult is a development platform written in Java. Built for modularization, JCatapult allows developers to build modules such as a blog, content-management system, wiki, or any other reusable set of features and use them across multiple applications. Built on top of open source technologies, JCatapult is a robust and scalable platform. However, it is also agile and lightweight because it uses a convention over configuration approach.
HTMLSplicer is a toolkit that provides methods to compose complex HTML documents from simpler HTML documents, called templates. It can be used to generate servlet responses in Java Web applications, without adopting a full-fledged presentation layer framework like JSP, JSF, Apache Wicket, or GWT.
LdapTemplate is a framework to simplify LDAP programming in Java, built on the same principles as Spring Jdbc. The LdapTemplate class encapsulates all the plumbing work involved in traditional LDAP programming, such as creating Contexts, looping through NamingEnumerations, handling Exceptions, and cleaning up resources. This leaves the programmer free to handle the important stuff: where to find data (DNs and Filters) and what do do with it (map to and from domain objects, bind, modify, unbind, etc.).
Jetspeed-2 is a full implementation of the Java Portlet API. It is fully compliant with the Portlet Specification 1.0 (JSR-168). It has passed the TCK (Test Compatibility Kit) suite and is fully CERTIFIED to the Java Portlet Standard. Notable features include security components backed by LDAP and database implementations, and some robust administration interfaces. Custom portals can be built and deployed using the Jetspeed plugin for Maven. Developers can use the Jetspeed PSML language to assemble portlets, and the Apache Portals Bridges project to 'bridge' portals with existing technologies including Struts, JSF, PHP, and Perl. For GUI designers, Jetspeed comes with several built-in templates used to decorate portals and portlets.
