Enterprise JavaBeans (EJB) Training: Introduction to EJB
|
Course Number: 275
Duration: 4 days (3 days upon request)
view class outline
EJB Training Overview
Introduction to EJB teaches attendees the skills they need to successfully develop all types of Enterprise JavaBeans, including session beans, entity beans, and message-driven beans. This course is taught using the EJB 3.0 framework.
Location and Pricing
Most Accelebrate courses are taught on-site at our clients' locations worldwide for groups of 3 or more attendees and are customized to their specific needs. Please visit our client list to see organizations for whom we have recently delivered training. To receive a customized proposal and price quote, please contact us.
In addition, some courses are available as live, online classes for individuals. To see a schedule of online courses, please visit http://www.accelebrate.com/online_training/java.htm.
EJB Training Prerequisites
All attendees should have a solid Java programming experience. Some experience with distributed systems development, especially object-based systems such as Java RMI, CORBA, or COM, is a plus. Some knowledge of JDBC is helpful in understanding the EJB persistence model. Understanding of XML is a plus but is not needed.
Hands-on/Lecture Ratio
This class is 70% hands-on, 30% lecture, with the longest lecture segments lasting for 20 minutes.
EJB Training Materials
All EJB training students receive a copy of Apress' Beginning EJB 3 Application Development: From Novice to Professional, related courseware, and copies of all files developed during the class.
Software Needed on Each Student PC
- Windows 2000, Windows XP, Windows Vista, or Windows Server 2003
- JDK 1.5 or later (1.4 can be accommodated upon request)
- JBoss 4.2.x or Sun Java EE RI 1.4 or later; WebLogic, WebSphere, and other containers can be accommodated upon request
- Development IDE of your choice; Eclipse recommended
EJB Training Objectives
- Understand the role of EJB in the broader Java EE platform.
- Describe the features that are implemented by an EJB container on behalf of application components.
- Build stateless session beans as part of a service layer or SOA.
- Build JPA entities to represent persistent data records within the Java application.
- Develop systems of entities to manage complex data models including 1:1, 1:N, and N:N associations.
- Manage transactional behavior of the application through declarative and programmatic techniques.
- Invoke EJB sessions from Java web applications.
- Use dependency injection and JNDI names to assemble complex web/EJB systems with minimal fuss and maximal flexibility.
- Implement message-driven beans to process queued messages asynchronously.
