Migrating to Struts 2
Added by Ted Husted, last edited by Ted Husted on Jul 13, 2007  (view change)

Learn how to intergrate existing Struts applications with the Next Big Thing: Apache Struts 2. After completing the course, you will be equipped to migrate or create professional Struts 2 applications.

The course covers migrating existing applications to Struts 2, with a focus on upgrading the most important asset of all: the grey matter between your ears. Along with migration issues, the course covers advanced development topics, such as creating a data access layer, securing web applications, and creating tag-based user interface components.

This course is intended for experienced Struts developers who to want to ramp up quickly and start developing with Struts 2 right away.


Experienced Struts developers and programmers who are considering Struts 2 for a current or upcoming project.

Course Objectives

  • Migrate Struts 1 classes and resources to Struts 2 equivalents
  • Build a working Struts 2 web application
  • Understand how to test and debug Struts 2 applications
  • Explore new features and key best practices

Course Format

  • Sessions include a presentation and a workshop.
  • Presentations are reinforced by workshops designed to explore common problems and best practice solutions.
  • Workshops are described with standard use cases.
  • Source code for the completed workshops is available through the Struts from Square One site.
  • Other course materials are available through this site (Struts University).


To benefit from this workshop training course, participants should have experience developing Java web applications with Struts, or another MVC framework (WebWork, Spring MVC, Tapestry). Experience with a modern Java IDE, such as Eclipse, IDEA, or NetBeans, is also beneficial.

Course Outline

Session Presentation Use Case Day 1 - Carpe Diem
1-1 Migrating to Apache Struts 2 Migrate We step through migrating a Struts 1 application to Struts 2 through a series of mini-labs. (More ...)
1-2 Building Struts 2 Applications Welcome We introduce the workshop outline and related materials. Then, we explore and extend a simple "Hello World" application that demonstrates the basics of web application infrastructure. (More ...)
1-3 Jumpstarting JUnit Retain The framework encourages a layered architecture, which implies a layered approach to testing. We look at interacting with the business layer through unit tests. (More ...)
1-4 Capturing Input Register Forms play a strong role in most web applications. How does Struts 2 help us harvest data submitted by a form? (More ...)
      Day 2 - Plumbing Matters
2-1 Validating Input Register ext Now that we are up and running, we ask "How do we get there from here?" (More ...)
2-2 Test-Driving Web Development Menu Once we know the business layer is sound, we can test the presentation layer too. (More ...)
2-3 Mapping Workflows Logout, Login The action mappings work closely with the result types to guide clients through the application. (More ...)
      Day 3 - Looking Good
3-1 Localizing Content Localize To reach the broadest audience, some applications support more than one language. Even if your application supports one language, the message resources are an effective tool for managing shared phrases throughout the application. (More ...)
3-2 Displaying Dynamic Content Profile Creating interactive screens can be the most rewarding and the most frustrating part of web development. Struts Action relies on JSP tags to display application state. (More ...)
3-3 Polishing the User Interface Subscribe Now that we have it working, let's make it pretty! (More ...)
3-4 Best Practices   Following best practices can help make an application faster to create and easier to maintain. (More ...)

Day by Day

Day One: Carpe Diem

We hit the ground running by migrating a simple "hello world" application from Struts 1 to Struts 2, and exploring the data access layer for the MailReader example application.

Preview: Welcome to the Workshop

We introduce the workshop outline and related materials. How will the workshop be presented? What will the workshop accomplish?

Day Two: Plumbing Matters

We fill in the blanks of web development by examining the sprockets and gears of framework internals.

Review: Carpe Diem

  • Infrastructure, infrastructure, infrastructure
  • Test first

Day Three: Looking Good

We focus on the glitz and glamor of the user interface, and then review best practices.

Review: Plumbing Matters

  • Input matters
  • Trust but verify
  • Click-thru tests

Review: Looking Good

  • Who, who are you
  • Think global, act local
  • Getting it back
  • Making it pretty
