PREREQUISITES: This course is designed for developers who wish to get into the world of enterprise Java Web development, and avoid all the pitfalls by learning about best practices and the best-of-breed solutions offered by the open-source community.
The participants taking this course must be familiar with Java and the general principles of object oriented programming (OOP).
Prior exposure to the following concepts and technologies is very helpful, but not required:
- General understanding of web development principles
- Basic knowledge of HTML and CSS
- Basic knowledge of JavaScript
- Understanding of Java 5 Annotations
- Basic understanding of the HTTP protocol, including concepts like SSL, redirection, GET vs POST, etc.
- Basic knowledge of SQL
- Familiarity with MySQL (or any other relational database)
- Familiarity with Eclipse IDE (or any other IDE)
- Familiarity with Tomcat (or any other Java EE application server)
- Familiarity with Ant

DURATION: 4 days. Hands on.

OBJECTIVES: This course teaches students how to develop enterprise Java web applications with the Spring, Hibernate frameworks.
The class is designed to run as a hands-on tutorial with more than 50% of time being devoted to writing code.
On completion, delegates will:
- Understand the fundamentals of Java Web Applications
- Know how to develop Java Servlets, explain the advantages, the disadvantages, and best practices
- Know how to develop Java Servlet Filters
- Know how to develop JavaServer Pages (JSP), take advantage of JSTL and JSP Expression Language (EL)
- Be able to package, deploy, and troubleshoot Java Web Applications.
- Understand how to access relational databases via JDBC
Be able to set up container-managed database connection pool (DBCP) accessed through JNDI
- Know how to configure container-managed security (authenticating against a relational database)
- Understand the drawbacks of bare-bones JDBC code and the benefits of an ORM solution
- Be able to install, configure, and use Hibernate (with Annotations) for the persistence layer
- Be able to install, configure, and use Spring for the Business and DAO layers
- Understand the advantages of POJOs and AOP-style development with Spring
- Be able to use Spring MVC to replace Servlets, get support for binding, validation, navigation, error handling, etc.
- Set up an application server for SSL, and learn how to selectively require SSL where needed
- Learn about AJAX, and how to use it with Spring through the Prototype JS library
- Learn how to use Eclipse for Java EE to help speed up the development efforts
- Learn how to automate common development tasks with Ant
- Learn best practices, and overall differences between Spring/Hibernate-based applications when compared to other solutions.
