J2EE

CDI (Contexts and Dependency Injection for the Java EE platform) is defined in JSR-299 and enhances support for dependency injection in Java EE 6. The more I use CDI the more I like it...However, I couldn't find a simple example of how to configure your application with CDI by reading configuration attributes from a file. Here is an example of how it can be done: Specifying injection points...

What I realized shortly after we put out Magnolia 4.3 is that while we tried to explain new multisite support for example in this screencast there are still plenty of grey areas and lot of confusion when people actually get to use the multisite support. And I think I wrote and talked about this topic earlier as well. Of course as with any new functionality, there are still...

In this post I will share my recent findings about Container Dependency Injection in Java EE 6, in particular how to decouple the processing threads of  event producers and event consumers. Java EE 6 introduces a very nice dependency injection framework (CDI) that has superb support for the Observer pattern in the form of event broadcasting. An Event in CDI is just a regular POJO: public...

A long time without blogging, I have been busy working with DTV applications and GRails... this post goes with the second topic... Have you already installed Spring Security (Acegi) plugin in Grails? Do you want to allow logins with the email also - like Twitter, SlideShare, etc - and not only with the default username? Here is the simple way to make it to work: 1 - Implement an...

EJB

Java EE Security refcard is available for download. This refcard covers Java EE 6 security and discuss how each application server supports the specs. The refcard covers authentication, authorization, and transport security in Web Application, EJB application and web services by introducing the concept and the related annotations and deployment descriptors which help us realize the concept....

On April 28th, 2010, we will be kicking off the first phase of FESI's research.  This where we set up the project, and start to get our hands dirty. Attached is the flyer we will use to promote FESI and what we're trying to accomplish.  Hopefully it will help us get the word out to the local community. Also as the kickoff, we'll be participating with a networking group that meets...

  Learning GlassFish v3 Command Line Administration Interface (CLI) Terminals and consoles was one of the earliest types of communication interfaces between a system administrator and the system administration layer. Due to this long time presence,  command line administration consoles become one the most utilized administration channel for configuring different software ranging from database...

Here is an example of yet another hybrid (OSGi + Java EE) application. This is a complete JMS consumer/producer example using OSGi and GlassFish. You can download the complete sample from here. How to use the sample: 1. Download <a href="http://weblogs.java.net/sites/default/files/osgi-jms-mdb-1.zip">osgi-jms-mdb-1.zip</a> and unzip it.2. cd osgi-jms-mdb-1/3. mvn clean...

Open Source

Here is the second part of the CAFE fundamentals blog series. This time, I am explaining two important interfaces called Communication and UserProcedure with an example. If this is the first time you are hearing about SailFin CAFE, I recommend reading the CAFE fundamentals article and the blog on writing your first CAFE application. The core of this discussion is an example which shows...

The Book in Details: Security was, is, and will be one of the most important aspects of Enterprise Applications and one of the most challenging areas for architects, developers, and administrators. It is mandatory for Java EE application developers to secure their enterprise applications using Glassfish security features. Learn to secure Java EE artifacts (like Servlets and EJB methods),...

Eclipse

The Bean Validation specification went final around the same time that the Java EE 6 specifications went final. The Java Persistence 2.0 specification allows for Managed classes (entities, mapped superclasses and embeddable classes) to be configured with Bean Validation constraints. In this example we are going to use Eclipse Galileo which you can download and then install from here. You will...

Last week's kickoff of FESI's research program went very well. There are a number of folks (>500) who are now following this blog on Java.net, and a number who have gotten involved.  While we wait for more folks, we'll be researching new technologies, the first being NOSQL databases.  If the kind of topics we're research interests you, please feel free to join the project;...

If you wonder whether the style of use with JDBC API has an impact of performance, you might like to read my latest blog entry on Head Crashing Informatics. While the entry mostly is about tuning SQL Anywhere's BLOB handling performance, it contains an interesting aspect: There are three ways to deal with BLOBs in JDBC, and the performance difference is tremendous. While obvious for the JDBC...

Programming

 I'v just published an integration module for using GridGain with Spring Batch. Using this module you can distribute Spring Batch processing inside a GridGain grid with the implementation of remote chunking. http://aloiscochard.blogspot.com/2010/04/spring-batch-integration-module...

JSR

I wanted to describe an interesting problem I recently faced that involved the most excellent JAX-RS specification and its Jersey implementation.  The quick overview is that we wanted the output of our JAX-RS resource classes to be client-agnostic, but we also wanted the ability to insert a decorator of sorts in between the objects we were returning and the normal JAX-RS serialization/...

JSP

I'm excited to show you all one of the things I've been working on since I joined Palm. Palm Hot Apps Today we launched a new microsite called Palm Hot Apps. This is a leader board for our Hot Apps promotion, where the top selling & downloaded apps compete to earn bonuses between $1,000 and $100,000 dollars. Since this is a competition we wanted to have a constantly updated site that shows...
