Beginning POJOs introduces you to open source lightweight web development using Plain Old Java Objects (POJOs) and the tools and frameworks that enable this. Tier by tier, this book guides you through the construction of complex but lightweight enterprise Java-based web applications. Such applications are centered around several major open source lightweight frameworks, including Spring, Hibernate, Tapestry, and JBoss (including the new lightweight JBoss Seam).
Using Hibernate to manage relational data in a Spring web application is not only an extremely powerful and scalable approach, but also widely used. In this course, we'll add a database to an animated GIF library, and discuss some more powerful features of Spring and Thymeleaf, such as HTML forms, file uploading, form validation, and flash messaging.
