Creating timers using the EJB timer service for enterprise beans
You can use enterprise beans to take advantage of the EJB timer service to schedule time-based events.Developing enterprise beans
One of two enterprise bean development scenarios is typically used with the product. The first is command-line using Ant, Make, Maven or similar tools. The second is an IDE-based development and build environment. The steps in this article focus on development without an IDE.Developing applications using the embeddable EJB container
Use this task to develop applications using the embeddable Enterprise JavaBeans (EJB) container. Applications running in the embeddable container start faster and require a smaller footprint than when running in the full application server. It is an optimal environment for quickly developing and testing applications that might eventually run on the application server.Configuring EJB 3.1 session bean methods to be asynchronous
Use this task to configure Enterprise JavaBeans (EJB) 3.1 session bean methods to run asynchronously. You can make some or all of your bean methods asynchronous.Developing session beans
Programming to use message-driven beans
Applications can use message-driven beans as asynchronous message consumers. You deploy a message-driven bean as a message listener for a destination. When a message arrives at the destination, the EJB container invokes the message-driven bean automatically without an application having to explicitly poll the destination.Assembling EJB 2.1 enterprise beans
Assembling EJB 3.x enterprise beans
Assembling EJB modules
An enterprise bean is a Java™ component that can be combined with other resources to create Java Platform Enterprise Edition (Java EE) applications. This topic describes assembling Enterprise JavaBeans (EJB) modules based on the EJB specifications.Developing EJB 2.x entity beans that use access intents
