Conceptual overviews

Documentation	Enterprise beans
	See Chapter 9 of the IBM Redbook EJB 2.0 Development with WebSphere Application Studio Developer (sg246819) Note: Version 5.x Redbooks are cited for their conceptual material. Product technical details have changed in Version 6. Refer to the product documentation for current product and technical details. Links to Version 6 Redbooks will be added as they become available. Redbooks are supplemental rather than formal product documentation. Read their Notices carefully. For information about supported configurations, consult the product documentation.

Tutorials

developerWorks offers these tutorials that accompanied the WebSphere Application Server Technology for Developers Version 6 release. They provide a solid understanding of the J2EE technologies. Tutorial 1 - JSP, Servlets, EJB This tutorial provides an understanding on the EJB Query Language, JSP Expression Language, building your own custom tags, and also about the new deployment descriptors which uses the XML Schema instead of the DTD. The zip file comes with all sample code required to run this tutorial. Tutorial 2- EJB Timer This tutorial provides an understanding on the EJB Query Language, JSP Expression Language, building your own custom tags, and also about the new deployment descriptors which uses the XML Schema instead of the DTD. The zip file comes with all sample code required to run this tutorial. Tutorial 3- Message Driven Timer This tutorial makes full use of the MyBank sample codes. The sample consists of 2 entity beans, CustomerBean and AccountBean, whose abstract schema types are Customer and Account, respectively. Each entity beans has remote/local interfaces and remote/local home interfaces. The entity bean CustomerBean has one-to-many relationships with AccountBean. The SenderBean.java session bean is responsible of sending message to the destination, and the MDB MyBankListenerBean.java is the consumer for the message. The zip file comes with all sample code required to run this tutorial.

Samples

The Samples Gallery offers: Plants by WebSphere Using the Plants by WebSphere storefront, customers can open accounts, browse for items to purchase, view product details, and place orders. The Plants by WebSphere application uses container-managed persistence (CMP), container-managed relationships (CMR), stateless session beans, a stateful session bean, JSP pages, and servlets. When the Greenhouse Supplier Sample application is installed and configured, an administrator can order additional inventory from the Greenhouse Supplier. See the Samples Gallery for more information on the Greenhouse Supplier application. The Greenhouse Supplier is used with Plants By WebSphere to demonstrate Web services. WebSphere Bank Using the WebSphere Bank online bank, customers can open accounts, get account balances, and transfer funds between accounts. The WebSphere Bank application uses Web services, Java Message Service (JMS) API, container-managed persistence (CMP), container-managed relationships (CMR), stateless session beans, Message-Driven Beans (MDB), JSP pages, and servlets. Greenhouse by WebSphere Using the Greenhouse by WebSphere online supplier, customers can open accounts, select items and amounts to order, and check their order status. The Greenhouse by WebSphere application uses Web services, the Java message service (JMS) API, scheduler, asynchronous beans, container-managed persistence (CMP), container-managed relationships (CMR), stateless session beans, message-driven beans (MDB), Java server pages (JSP) files, and the struts framework. BMP - Address Book A basic address book application that creates, updates, finds, and removes address book entries. The Address Book application uses Bean Managed Persistence (BMP). CMP 1.1 - Movie Review A movie review application that creates and finds movie reviews. This Movie Review application uses Container-Managed Persistence (EJB 1.1 CMP). CMP 2.1 - Movie Review A movie review application that creates and finds movie reviews. This Movie Review application uses Container-Managed Persistence (EJB 2.1 CMP). CMR - Subscription A subscription service, where you can enter an e-mail address and select programming topics. This application uses Container-Managed Relationships (EJB 2.0 CMR). Stateful Session - Reading List View library-like resources. Add and remove resources from reading lists, using a stateful session bean. Stateless Session - Basic Calculator A basic calculator application that performs addition, subtraction, multiplication and division, using a stateless session bean Timer Service - Bulletin Board A bulletin board application, where you can enter a message and post it for a specified length of time. This application uses the EJB Timer Service.
