Java Enterprise

A new, two-part tutorial explains the process that involves Sun Secure Application Switch and Sun Java System Application Server—a process that also works with other leading application servers. The tutorial includes a section on advanced configurations, in which is a description of alternative deployment architectures.Way to go for large-scale deployments! You are assured that load-...

A new developers.sun.com article highlights the features of the free preview release of the Java Enterprise Edition 5 SDK and Sun Java System Application Server Platform Edition 9 Beta. The latter stemmed from the combined efforts of Sun engineering and the open-source Project GlassFish.What an impressive list: Persistence API, JavaServer Faces 1.2 technology, Web services and SOA, call-flow...

A new article on developers.sun.com, Namespaces in XML Schemas, Part 2 of Two-Part Series, describes, along with code samples, the nuances of developing aggregate schemas with import and include statements. 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...

You can find out at a glance on the home page of the release. It's an integrated bundle of the previews of NetBeans 5.5 and a future release of the Sun Java Studio Enterprise IDE, also Sun Java System Application Server Platform Edition 9 Beta, the first product of Project GlassFish.

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...

I'm pleased to announce another revision of the Java EE Web Tier. In Jan Luehe's blog you can find out what's new in JSP 2.1 Proposed Final Draft 2 (PFD2). 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...

A colleague of mine entered our room a couple of days ago and asked me this: can he open a Swing frame from the application server in order to view the request that he got (a pretty big XML string)? Sounds strange, right? So many reasons not do this: What happens with this code in production? Why not use Eclipse debugger, copy the request to XMLSpy and view it there? Why not configure the log...

With traditional Action MVC frameworks (Struts), you have a specific set of scopes to store state in over transactions: request, session, and application. Often, while developing applications with Action MVC frameworks, you have to make a decision to store objects/state in the request or the session. There can be consequences to the the performance of your application in either case. You can...

Take a look at this blog by Ken Drachnik, who heads product management of Sun Java System Application Server at Sun. In clear terms, the blog explains the differences between Project GlassFish and Sun Java System Application Server. One can well picture the intense engineering in the background--all good stuff! I'm also coauthoring articles on GlassFish and will introduce them here as soon as...

With the help of Kohsuke Kawaguchi's most excellent maven java.net plugin, and several iterations of trial and error, we now have the JSF 1.2 api and impl jars available under the same license as Glassfish on the java.net maven repository. Put this in your project.properties or build.properties: maven.repo.remote=https://maven-repository.dev.java.net/nonav/repository/,http://www.ibiblio.org/maven...

The J2EE 1.4 SDK just got updated, and we could not be left behind with our solutions catalog that runs on it. This version of the solutions catalog uses J2EE 1.4, and covers the following topics: Asynchronous JavaScript and XML (AJAX) Web services Web Tier Design with JavaServer Faces Business Tier Design Download it here.This version is also integrated in the Netbeans 4.1 and 5.0 IDEs:...

I have been having a look at EJB 3.0 interceptors with Glassfish. EJB 3.0 allows you to define interceptor methods that are called around the business methods and lifecycle events on the bean instances. The interceptor methods can either be defined within the bean class or in separate interceptor classes. Interceptor definitions and binding interceptors to bean classes or specific methods within...

To make Sun Java System Application Server work with Object Reference Broker (ORB) software, all you need to do is revise a few server-side settings. A brand-new article that I cowrote with Sun engineer Sheetal Vartak, Configuring Sun Java System Application Server for Third-Party ORBs, steps you through the procedure and offers tips.As background on ORB, the Object Management Group has published...

It was pointed out to me on the ##jsf channel on irc.freenode.net that we didn't have a link to the source snapshot for the JSF 1.1_01 build. This has been fixed and I've updated our java.net page to include a link to the 1.1_01 source released under the Java Research License.

In November I had the chance to speak with developers at the JavaOne Japan event on AJAX. In Japan, there is a strong interest in AJAX and from some conversations with developers and companies following the conference I realized that AJAX really is a global phenomenon. Last week I had the chance to speak at Apple with some of the developers from the Apple Store about AJAX and to my surprise I...

As announced by Jonas Jacobi in his blog, Oracle has donated portions of its ADF Faces component library to the MyFaces project. This library is JSF 1.1 based. I'm writing to let you know that, due to Oracle's participation in the JSF 1.2 expert group, these components have already been tested with Glassfish and run quite well under JSF 1.2. Furthermore, the MyFaces tomahawk components also...

In one my last blogs on the concepts behind Avatar involved trying to gain performance via AJAX by partially processing a UIComponent tree in JSF. I'd like to bring another possible idea up with JSF: what about treating all components as stateless? Not stateless as in Servlet-stateless, but stateless as in request scoped. As mentioned in the Avatar blog, component tree creation is dirt cheap (...

Courtesy of Karthik Rajeswaran of the Sun Java Studio Enterprise QA team-- Anyone who's encountering problems in running Web applications that are developed with JDK 1.5.0 characteristics (such as generics) on Apache Tomcat 5.5 should read a recent thread on the Sun Java Studio Enterprise forum. From there, you learn how to configure Sun Java Studio Enterprise 8 and Tomcat 5.5 to be compatible...
