Course Summary
This intensive 5-day training course is designed to give students a jump start to enterprise Java web application development with best-of-breed software stack: GWT, Spring, and Hibernate
In this course, students will build Rich Internet Applications (RIA) using Google Web Toolkit (GWT) and connect with Spring-powered backend. Persistence is implemented with Hibernate object-to-relational mapping (ORM) framework.
Duration
5 days.
Objectives
At the end of the course, you should gain an understanding of GWT, Spring, Hibernate and associated technologies and be able to:
- Develop browser-based web applications using GWT
- Use Spring service components for implementing the back-end business logic
- Make use of Spring’s support for transactions
- Code the persistence tier in Hibernate annotations framework
- Leverage from Hibernate validator framework to validate the domain classes
- Unit test GWT, Spring and Hibernate out-of-the-container using JUnit
Audience
Developers interested in developing Rich Internet Applications (RIA) with GWT and leverage from Spring-powered Java EE apps in the middle tier and Hibernate in the persistence tier.
In order to get the most benefit from this training students must have experience with developing core Java applications. Familiarity with SQL and general web-app development concepts is a plus.
