J2EE applications, both Web and EJB, often need to set configurable parameters such as a timeout value, retry count, and so on. This blog discusses two ways of externalizing these values, so that a deployer can change them without recompiling the code.
I'll have the privilege to serve on the selection committee for the
web-tier related submissions for the upcoming
JavaOne conference. Got any advice I should bring to the committee?
I am glad my original post about Practical AOP and Transparent Remoting has received polite and smart comments against it. This is definitely a nice way to get the discussion about AOP going! Here are my answers to these comments.
Many people have demonstrated they fear AOP or that they can't understand its applicability besides logging and other common examples.

The transcript is now available for our Dec 7th SDN chat on JSP 2.1 / Faces 1.2.
On Tuesday Dec 7th at 11:00 AM Pacific, Roger Kitain and I will be hosting a JDC chat on the Faces 1.2 and JSP 2.1 technologies, which are part of the upcoming J2EE 5.0 platform. We look forward to chatting with you! The chat can be found at http://java.sun.com/developer/community/chat/index.html
J2EE-SDK project has just launched with the goal of building a developer community around the J2EE SDK.
Localization seem to be a never ending topic. Here are some questions on the subject, occasionally followed by answers.
Apache Derby is the latest database to join the OpenSource ranks. It is easy to get Derby working with the J2EE SDK.
Help to shape the next version of the Java AVK for the Enterprise by taking a short survey.
An early draft of the EJB 3.0 spec was released on June 30th and we encourage you to read the spec and provide your feedback.
After several years of internal development, Sun felt it was time to open our kimono and share the source code of the official Reference Implementation for JavaServer(TM) Faces technology with the world. In this blog, I welcome you to the project, share the development model we have used to bring the project to its present state, and give some insight into where we want to go in the future.
J2EE developers who have not downloaded the the Java Application Verification Kit for the Enterprise
should do so and incorporate it into their normal development process.
Exception chaining has become an increasingly popular pattern as a way to better manage exceptions. As part of JDBC 4.0, we are giving consideration to introducing exception chaining to the primary exception class definition: java.sql.SQLException.
I'm still surprised at how many people are confused about Sun's J2EE 1.4 SDK. For example, did you know it is free? Really free, even for deployment?
The jstl-spec-public project has just been launched to increase
transparency into the JavaServer Pages Standard Tag Library (JSTL)
After diving into the message-driven bean section of the EJB 2.0 specification, all is not what it seems with regard to message redelivery.
In this weblog, I look at how service-oriented architectures are an evolution of the structured programming, object-oriented programming, component-oriented architectures in terms of unit of resuability.
"hey, wouldn't it be great to have a community on java.net centered around J2EE applications, components and tools?"
