Spring into Seam, Part 2: When stateless and stateful collide
You say adding stateful behavior to Spring beans is too much work? Maybe all you need is a little extra muscle from JBoss Seam. (Excerpted from Seam in Action, forthcoming from Manning Publications.)

Spring into Seam, Part 1: Build a Spring-Seam hybrid component
Who says adopting Seam means giving up Spring? In this first installment in a three-part series, Dan Allen shows you how to build hybrid components that benefit from both Seam and Spring container functionality. Excerpted from Seam in Action, forthcoming from Manning Publications.

Is Tomcat an application server?
Whether Tomcat is an app server depends in part on how you're using it, but that's not all. Jeff Hanson explains the formal differences between app servers, Web servers, and Java EE containers, and also explores usage scenarios where Tomcat is -- and is not -- appropriate as an application server.

From Java EE security to Acegi
Application security as an enterprise-level concern needs to be carefully addressed by developers. This article compares the security services defined in Java EE and Acegi to help developers select the appropriate security services and program security from an enterprise-wide view.

The year head: The shift to scripting and agility
Enterprises will spend too much this year creating monolithic apps. Most would be better off using scripting languages, Web services, and SOA (service-oriented architecture) to weave together browser-based apps that leverage existing assets.

Leverage Spring Web development with Offspring
This article introduces Offspring, a Spring-based Web framework extension. It accelerates and simplifies the design and implementation of Web applications by reusing aspect-oriented modules, thereby separating the responsibilities of the software components and hiding the Java Spring specifics from the development process. Extreme flexibility is achieved by combining the generic framework with specialized modules called executors. Examples from the real Website www.whowillbethere.com, which was built on the principles of Offspring, illustrate this proof of concept.

Solving the logout problem properly and elegantly
Properly handling the logout process in a password-protected Web application requires more than just calling the invalidate() method on the HttpSession object because most modern browsers, with the Back and Forward buttons, allow users to go back or forward on a page. If the Back button causes the browsers to display stale pages from their caches after the logout process, users of these inadequately-developed applications can become confused, lost, and wonder what has or could have happened to their personal data. Many Web applications put up a page threatening users to close their browsers completely, thus, in effect, preventing them from clicking the Back button. Others use JavaScript, which is not always active on clients' browsers. Most of these solutions are either awkwardly implemented, fail to work 100 percent of the time under all circumstances, require too much training on behalf of users, and/or compromise the user experience. This article presents solutions for properly handling the logout problem along with sample programs. Author Kevin Le starts by describing an ideal password-protected Web application. He then uses sample programs to illustrate how the problems manifest themselves and discusses the solutions required to fix the problems. By centering the discussion on JavaServer Pages (JSP), the article presents the concepts that can be easily understood and adopted for other Web-tier technologies. Le concludes his discussion by showing how building Web applications with Jakarta Struts can more elegantly solve the logout problem. Sample programs for both JSP and Struts Web applications are included.

Struts best practices
Multiple options are available for solving problems with Struts. When deciding among these alternatives, the choice must be based on parameters such as the scale of work and availability of time. However for large applications and the best quality-of-service needs, every decision becomes crucial and extra efforts are required to choose the appropriate solution. To help you make these decisions, Puneet Agarwal discusses some of the best practices for developing Struts-based applications.

Servlet and JSP performance tuning
In this article, Rahul Chaudhary describes performance-tuning techniques (PTT) that can be used to improve the performance of servlets and JSP pages, thus improving the performance of your J2EE applications. The author assumes the reader has basic knowledge of servlets and JavaServer Pages.

Multibyte-character processing in J2EE
Most J2EE servers can support multibyte-character languages (like Chinese and Japanese) very well, but different J2EE servers and browsers support them differently. When developers port some Chinese (or Japanese) localized applications from one server to another, they will always face multibyte-character problems. In this article, Wang Yu analyzes the root causes of problems related to multibyte characters and provides some solutions and guidelines.

Isolate server includes' runtime context
Dynamically included JavaServer Pages (JSP) pages and servlets offer simple, but limited means for frontend code encapsulation and reuse. A dynamically included resource often relies on runtime data (request parameters, JSP-scoped attributes), and this restricts the runtime context from which it can be included. This article shows how to achieve true black-box reuse of frontend logic in the form of JSP pages or Java servlets, by wrapping the servlet request object and effectively creating a local runtime context for an included resource.
