Dashcourses has partnered with GogoTraining to bring you this Self-paced Course.

In this self-paced Introduction to Hibernate technical training course, JSP and servlet programmers will learn how to integrate their enterprise applications with the open-source Hibernate framework for persisting information to databases. Students will learn how the Hibernate architecture implements best practices in Web application Development for persisting information to databases.

Training Objectives

As a result of this training, students will be able to:

  • Install and configure the Hibernate product using XML.
  • Explain how Hibernate maps a database table or entity to a Java object.
  • Use Hibernate Query Language (HQL) to query and update database entities through Hibernate objects.
  • Map unidirectional and bi-directional relationships in Hibernate.
  • Implement inheritance in Hibernate mapping.
  • Control transactions in Hibernate.
  • Control caching and perform other advanced efficiency optimizations within Hibernate.

Prerequisites

  • Familiarity with Java programming, Servlets programming, JSP and JavaBeans; familiarity with Web page development (HTML and XML).
  • Minimum software requirements: Java Enterprise Edition Software Development Kit (Java EE SDK). JavaServer Faces (JSF) visual development environment, such as Eclipse, NetBeans or Sun Java Studio Creator. Apache Tomcat. Hibernate development framework (downloadable from www.hibernate.org) Optional JDBC-compliant relational database, such as Oracle, MySQL or Microsoft SQL Server.
  • Minimum hardware requirements: Pentium at 1.5 GHz, 1 GB RAM; 5 GBfree hard disk space before installation. Internet access.
