Kurs informasjon: Developing Applications with Java Persistence API (JPA) (Self-paced)

NOTE: THIS IS AN ONLINE SELF-PACED VIRTUAL COURSE. PLEASE DO NOT MAKE TRAVEL ARRANGEMENTS FOR THIS COURSE.

Self-paced virtual courses provide the same deep technical content as our classroom courses, but allow you to learn on your own schedule. You can stop and start a Self-Paced Virtual class as needed during the 60-day access period.

There is no live instructor for this course, so it may not be appropriate for students who require the guidance of a live instructor. In such cases, students should consider the alternative versions of this course:

• Classroom delivery: Developing Applications with Java Persistence API (JPA) (WD160)
• Instructor-led online delivery: Developing Applications with Java Persistence API (JPA) (Remote Classroom) (VD160)

This 2-day instructor-led course teaches students how to build, develop, and run Java applications that use the Java Persistence API (JPA). Students use IBM Rational Application Developer V7.5, which provides complete support for the JPA specification, to develop the JPA-based applications in this course.

JPA provides a mechanism for managing persistence and object-relational mapping. It represents a significant evolution over previous persistence techniques, such as Java Database Connectivity (JDBC) and EJB 2.0 Container-Managed Persistence (CMP), and it can be used in both Java Standard Edition (Java SE) and Java Enterprise Edition (Java EE) applications.  

This course begins with an overview of persistence and the JPA specification, including features of the Java Platform that support JPA and JPA architecture. Subsequent topics include creating JPA entities, using Java Persistence Query Language (JPQL) and performing object-to-relational mappings (ORM) for persistent data. Students also learn how the use of JPA in applications differs between the Java SE and Java EE environments.

Hands-on exercises throughout this course give students practical experience developing JPA-based applications with IBM Rational Application Developer V7.5. JPA development skills covered in the exercises include creating entity classes, developing a Java SE application to perform database operations, mapping entities to single and multiple tables, and working with JQL queries.

Note: This course covers the use of JPA in Java Standard Edition and Java Enterprise Edition Web container environments. It does not specifically address the use of JPA with Enterprise JavaBeans (EJBs). To learn how to use JPA entities running in an EJB container, students should attend one of the following courses:

• Developing EJB 3 Applications for WebSphere Application Server V7 (WD352)
• Developing EJB 3 Applications for WebSphere Application Server V7 (Remote Class) (VD352)

Students should have practical experience with the Java programming language. This knowledge can be gained by successfully completing one of the following courses:

• Java SE 5 Programming Fundamentals (WD152NO)
• Java SE 5 Programming Fundamentals (Remote Classroom) (VD152NO)
• Java SE 5 Programming Fundamentals (Self-Paced) (ZD152NO)

Students should also have knowledge of database concepts such as SQL, primary and foreign keys, joins, and referential integrity.

In addition, the following are beneficial, but not required:

• Experience using JDBC
• Some knowledge of Java EE Web development
• Experience using Rational Application Developer or another Eclipse-based development environment

After you enroll in this course, you will be directed to a link to help you prepare your system to access the course.

The computer you use to access the labs should meet the following requirements:

• Microsoft Windows 2000 or higher
• Minimum 512 MB of memory
• Microsoft Internet Explorer V7 or higher, or Mozilla Firefox V3 or higher
• Citrix ICA Client installed
• Access to the Internet

If you are running Windows 2000, ensure that your Internet Explorer uses 128-bit encryption. You can verify this by opening Internet Explorer and selecting Help - About Internet Explorer. If 128-bit is not listed, download and install the code from Microsoft.

The following network configurations will not work with these labs:

• Dialup connections
• Proxy Automatic Configuration (PAC) scripts loaded on the local machine (using file:// under Use automatic configuration script in Internet Explorer's Local Area Network (LAN) Settings); use a PAC script on a Web server (using http://) instead
• Web Proxy Auto Discovery (WPAD) only configurations; contact your location's network administrator about alternative configurations

The following configurations may or may not work with these labs, but are not supported:

• Citrix Clients under the following operating systems:
  • Windows 95
  • Linux
  • UNIX
  • Macintosh

• Web browsers other than Internet Explorer V7 or higher and Firefox V3 or higher
