AsyncWeb, the high-throughput non blocking Java HTTP engine who support asynchronous request processing from POJO objects, can now run on top of Grizzly, the http engine used by GlassFish. AsyncWeb can now be deployed in GlassFish. AsyncWeb is (from the site): AsyncWeb (built on top of the excellent Mina network framework) employs non-blocking selector driven IO at the transport level, and is...

Sun recently announced two initiiatives at JavaOne 2006 to AJAX enable JSPs and JSF components - jMaki and JSF-Extensions. When we announced the efforts, there was confusion about the two and it was viewed as the two technologies were competing. This document helps resolve the confusion and show that the two technologies are complimentary. Before we move to the discussion of jMaki and JSF-...

I am getting ready for the fall semester. My software engineering students will be using GlassFish for their projects. In order to avoid the "but it worked on my computer" syndrome, I make them deploy their apps on a server in my office. I just installed Ubuntu Server Edition. These instructions got me started with the Linux basics. This blog has the (not so) gory details for...

This code as been shown many times before, including in my book. This is exactly what the title says: a JSP that will display the request headers sent by your browser. It is also a good example of how to use the JSP EL and the JSTL core tags to make an incredibly simple JSP. Here is the code. Simply copy and paste it in to a JSP, ideally one that you are editing in Netbeans. You must have the...

The last decade of the XXth century was marked by the HTML advent, from a simple language rendered by the Web Browsers to the standard de facto of Internet contents: web-pages, mail and business applications. Several interesting innovations were applyied to the first draft of the HyperText Implementation in order to support the e-commerce demand, including multimedia tags and dynamic web layouts...

JPA is the new object-relational mapping standard that you can use in EJB3 or in standalone applications. For the most part, it is phenomenally easy to use. But ever so often, you get a query from a developer such as this one. The programmer set up a bidirectional relationship and didn't populate both sides.            ...

Readers of my blog know about Elvis, the Microsoft persona of the programmer who is neither Einstein nor the point-and-click/drag-and-drop "just give me a wizard" Mort. Elvis wants to use EJB 3 because the annotations make it easy, but he is a bit taken aback by the jargon. I am working on a glossary that gives both the official definition of various terms (starting with...

Often when you are "heads down" developing a technology, you forget about who might be using that technology. And in the course of giving a presentation about the technology, you may hear a question or two like "yeah... great.... but who is using this out there in the real world?".. Well.. we've compiled an initial list of companies/sites out there that use JSF.... That list can be found here...

As you know M7 is the final, Java EE 5 compatible release for GlassFish v1. It is a production quality, deployable app server. GlassFish v1_UR1 is the follow up bug fix only release to M7. v1_UR1 starts from the same source base as M7 and adds selected bug fixes only. M7 is the current stable release. v1_UR1 has additional, limited bug fixes and those builds are pretty stable. The next...

TmaxSoft (yes, where I work now) achieved it (of course except the Sun RI :-). See http://java.sun.com/javaee/overview/compatibility.jsp for more details. We are planning to release some preview as well. Thank you all for your great help, especially Alan, Arthur, and Stephen from the Sun CTS team. I couldn't forget such a beautiful weather in Boston. P.S. More about this to come, so stay tuned!

As announced by Jonas Jacobi, the Oracle ADF Faces component library project now has a new name, Trinidad. Trinidad now joins Tobago as sister projects providing opensource JSF component libraries, just as Trindad and Tobago (the countries) make up a twin island republic from where I originate. It is nice to have Trinidad and Tobago not only get notariety for their brave World Cup play but also...

Recently I have been exploring the various security features in Glassfish AS. In this blog entry, I hope to share some of my initial findings related to role based access control. The following simple problem highlights the need for different roles. Lets say, user 'X' can perform transactions as well as view non-transactional parts of the application. However user 'A' can only view access the...

Bonjour, comment Java? I'll be attending the JBoss World Vegas conference next week in Las Vegas, doing some Java EE 5 demos during Bill Shannon''s (Java EE 5 overall spec lead) talk. The "Java EE 5" talk is at 2:20pm on Wednesday. See the agenda. This will be the occasion to meet Emmanuel Bernard, the lead for Hibernate at JBoss, an expert group member as well. I guess we'll be preparing...

The GlassFish BoF on Tuesday evening of JavaOne was well attended with lots of great questions. Jim, Amy and I gave a quick overview of GlassFish, where we are today, highlights on the community and roadmap with future directions. I have posted the slides here . As I mentioned there were lots of questions during the 50 minute BoF and luckily there were many GlassFish developers, architects...

Switching the Java Persistence provider is straight forward and seamless if project /product uses Java Persistence API (EJB3.0) either as a standalone framework component or in a container managed environment. In my earlier blog entry, I had used TOPLINK as a provider and switching to use hibernate as a provider is fairly easy. Here is what one need to do. None of the source code changes but the...

Lately I have been tinkering with Glassfish and happened to look at the persistence API. The persistence API is based on the EJB 3.0 specification and is made available as a standalone component. I must admit that it’s fairly straight forward and a pleasure to use. After downloading the persistence API from Glassfish Persistence. I started with the examples provided along with the...

Wow....still recovering after a crazy week at JavaOne. We have worked very hard to make the keynote demo on Friday to clearly demonstrate the power of the Real Time VM. For people that didn't see it, we demonstrated SJSAS 9.0 running on the upcoming Sun Real Time VM. Without going into details (will blog more later on the topic), we have configured Grizzly to use its ARA mechanism and a Real Time...

Earlier we had shown how to plug in Hibernate in GlassFish. Now it's time for Kodo, which is another high performance & popular O/R mapping solution. Recently Kodo 4.0GA was released and it supports Java Persistence API 1.0. So, I thought I shall give a try using it in GlassFish. The instructions are really simple. They do not involve any unreasonable steps. Step #1: Download and install...

For an inside scoop on the Java EE 5 platform and EJB 3.0 technology, check out the two-day expert-to-engineer seminar in early June, complete with demos and Q&As. The seven sessions also address such popular topics as Java persistence, Web services, the Web tier and JavaServer Faces (JSF) technology, Java blueprints for AJAX-enabled applications, and Sun Java System Application Server PE 9...
