Tutorials

developerWorks offers these tutorials that accompanied the WAS Technology for Developers V6 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.
