Have you ever wanted to provide text formatting in a Swing control? Have you ever wanted to have multiple lines of text in a tab? This tutorial will show you how to use the simplicity of HTML to provide flexible and powerful text formatting in Swing controls.

The BeepLite Networking Layer is a Java implementation of Blocks Extensible Exchange Protocol, a generic application protocol kernel for connection-oriented, asynchronous interactions. This technology supports dynamic, pluggable application protocols for peer-to-peer, client-server, or server-to-server scenarios.

In this article we will learn how to manage the persistence issues without being tied to use a J2EE application server.
We will build a very basic sample application that saves and loads data on a database using an EJB 3.0 persistence implementation.

At present (April 2007) there exist two implementations of the EJB 3.0 persistence specification: the first is Hibernate-based and was adopted by JBoss, while the other is Oracle Toplink, included into the Oracle Application Server OC4J and into the EJB 3.0 Sun Reference Implementation also known as Glassfish Project .
Note that EJB 3.0 persistence specifications are only a part of the EJB 3.0 specifications. They do not deal with Session Beans (stateless or stateful), but only with the Entity Beans.
Well, the good news is that, as long as we need only the EJB 3.0 persistence layer and do not need Session Beans, we can use Hibernate or Toplink implementation (our choice!) just into any Java application, without the need of a J2EE container, not even a web server, just from a plain Java class!
