Java Enterprise

As its title suggests, a recent article in synnovation (an EDS Agility Alliance publication), Not Just a Spectator Sport, elaborates how access control and identity management nowadays mean a lot more than the traditional sign-ons with user IDs and passwords. They mean using open, standard protocols to implement application models that offer definitions of "rights, responsibilities, roles, and...

Frameworks of Today All MVC frameworks basically operate within the same 5 phases: Decode Interpreting state/parameters passed from the client Validate This involves validating the information decoded and possibly authorization/authentication Update Once the submitted information is validated, update the Java model Invoke Some controller behavior is handled here, such as an action once state is...

Hot off the press on developers.sun.com are parts 1 and 2 of a series on Business Process Execution Language (BPEL). Part 1 introduces the concepts and cites a sample process; part 2 describes how to define and apply the partnerLinkType and partnerLink elements to specify the relationship between a process and its partners. With the preview release of NetBeans Enterprise Pack 5.5, you can develop...

Here is an ultra-quick blog entry sharing something in JSF 1.2 about which I'm not sure many people are aware. Thanks to the unified EL, it is possible to refer to JSF managed beans and other JSF concepts using plain old JSP expressions in the page. For example, let's say you have a JSF app that is a bookstore. In the app is a managed bean that is a Map where the keys are ISBN numbers and the...

Internationalization (i18n) is easy if you are using AJAX and Java. Both Java and JavaScript have i18n capabilities though it is not obvious how to use those capabilities are not from an i18n background. I have re-worked the Realtime Validation with AJAX example to be i18n enabled. Follow these steps on the client and server to support i18n. On the client: Set the content-type in your pages...

The content and ideas in this blog entry are taken from my upcoming McGraw Hill Osborne book JavaServer Faces: The Complete Reference, which I am co-authoring with Chris Schalk. In the book, we have a chapter on Securing JavaServer Faces applications. This excerpt shows how the extensible design of JavaServer Faces can be used to allow JAAS to provide authentication to a JSF Web application....

Background In a previous blog, "New Feature for JSF 1.2", I concluded with a few sentences on breaking through traditional MVC with JSF: At the 30,000 foot view, here we've broken through the traditional URI/resource in request/action based frameworks such as RoR, where each thing you want to partially handle has to be separated out and coordinated as a specialized endpoint. Not so with JSF since...

I'm currently working with the good folks over at Skills Matter to develop a course based on my book, JavaServer Faces in Action. I'm pretty excited about this, as it will open up a specific version of my customized courses for use in the UK. In addition to covering the basics of JSF, the four day course will also several JSF products and technologies, such as IDEs, components, and open source...

In response to my SOA/ESB Level Set blog entry, I got the following question from cparziale: "In researching esb direction, I'm trying to assess if a "service bus" is a just another service 'on the side' of the primary services, to be used when needed, like UDDI, or if it will become a physical mediator of all service consumer-provider conversations. I ask because I'm trying to visualise what...

A new, detailed article on developers.sun.com tells you how, step by step. Bottom line, as the two coauthors keep emphasizing to me: It's easy; it's simple; it's straightforward; it's intuitive. User experience is a high priority in the design of Project GlassFish.The article addresses a variety of topics, including registry and security. I hope you find it helpful and illuminating.

With the demise of the Sun Engineer's Sandbox, my content posted there has disappeared. Thankfully I saved a copy. Thanks to srcerer on the ##jsf chat room on freenode for reminding me to repost this. Overview To celebrate the release of Ruby on Rails (RoR) 1.0, I have taken the flash concept from Rails's ActionController and brought it to JSF. For those unfamiliar with RoR or the flash, the...

Servlets sit at bottom end of the API stack for web developers using Java technologies. If you have used JSP, JSF, Struts, Web Work, Velocity, or any of the other frameworks out there you have more than likely used the Servlet API. What do I like about the Servlet API? As a developer I like being as close to possible to HTTP as possible and Servlets lets me do that well. The Servlet API has...

The saga of Oracle ADF Faces on the Java EE SDK continues. In our last installment, Adam Winer explained why ADF Faces won't run on Glassfish. I'm happy to report that after some minor tweaks to Sun's JSF implementation in the Java EE SDK, I think I have it running. However, I would appreciate any testing people could give to see if the entirety of ADF Faces works. ADF Faces is a large piece...

First off, thanks to the JCP and JEE EG for allowing us to add this feature so late in the game. The system *does* work! Now, on to the details... The core of JSF views are mutable component trees, uniquely identified, black boxes of encapsulated features that can be dropped in and combined in the true academic definition of a 'component'. Each component can participate not only in rendering,...

Lots of flexibility there!Schema characteristics are supported in an upcoming release of the Sun Java Studio Enterprise IDE, a preview for which is part of the integrated bundle NetBeans...

The beta for the Java EE 5 SDK is now available here and a set of tools that works with it is available here (the follow-up to J2EE 1.4 is Java EE 5, and that for J2SE 5.0 is Java SE 6 - the "2" is dropped and the "Java" is spelled out - it all makes sense but it can be confusing). Today's releases are a pretty big deal and there are already several blogs, discussions, technical papers, and...

The Change Log for Servlet 2.5 will give you the scoop on the Servlet spec. This blog entry will show what's new in the JSF spec. In JSF, the most visible new feature since the last draft of the spec is the addition of the invokeOnComponent...
