XOM Design Principals by Elliotte Rusty Harold

XOM (XML Object Model) is an open source API for processing XML with Java using a streaming tree model. Although it is open source, XOM was implemented using the cathedral model of development (one designer's vision) rather than the bazaar model. This JavaPolis talk by Elliotte explores the design goals, basic API principles, XML principles, Java restrictions and requirements, and testing techniques and tools that have informed XOM's development. In the process, Elliotte identifies some general principles of API design for all Java libraries and systems. Login to view this talk

Using JMX Technology Today and Tomorrow by Eamonn McManus

The Java Management Extensions (JMX) API is now part of the core Java platform. As such it is increasingly widely used. In this session, the Specification Lead for the JMX API will discuss some of the interesting ways in which JMX technology can be combined with other contemporary technologies such as Aspect-Oriented Programming and Dependency Injection to provide clean and unobtrusive ways to add instrumentation to applications. Then the session will cover some of the enhancements to the API that will appear in the forthcoming Mustang release of the Java platform. Finally we will look at some of the important new features that will appear in the subsequent release, code-named Dolphin, such as Virtual MBeans, Cascading (federated MBean Servers), and Web Services access.

Java Business Integration by Ron Ten-Hove

Java Business Integration (JBI) is a new Java standard, defining a framework for creating service-oriented architectures (SOA's) using plug-in components. This presentation will familiarize you with what JBI is, and the technical underpinnings that make it work. You'll learn about service-orientated integration, interoperable component models, and how the seemingly simple concept of message exchange patterns is the key to interoperation in JBI. This talk will be of value to two developer audiences: those who are interested in building plug-in components for JBI, and those who are interested in building complete integration or application using a SOA such as JBI-based systems.

Hi,

Just to let you know that we've today exceeded 16.000 registered wiki users on the JavaPolis site.
Party at my place when we reach 20.000 JavaPolians

We're in the process of selecting topics & speakers for JavaPolis 2006 (December 11th till 15th).
Because of the huge interest we'll send out an RFP for both the BOFs, Quickies and RAD Race.
The university and conference speakers will mainly be hand-picked by the 10 steering members.

A new wiki space will get released around the end of june, beginning of july...

Keep your eyes open on our wiki !

Cheers,

Stephan

JDK 5.0 is a huge step forward in developing concurrent Java classes and applications, providing concurrency building blocks for both novices and experts. This talk explores the new low-level concurrency utilities included in JDK 5.0, and examine their features and scalability.

Prior to the release of JDK 5.0, the Java platform provided basic primitives for writing concurrent programs, but they were just that – primitive – and difficult to use properly. In addition to many new high-level concurrency utilities, such as semaphores, mutexes, barriers, thread pools, and thread-safe collections, JDK 5.0 also includes a number of JVM-level enhancements for concurrency, and a set of low-level concurrency utilities for developing highly scalable, nonblocking concurrent algorithms in Java.

Even with built-in support for locking, it has not been practical to develop nonblocking concurrent algorithms in Java prior to JDK 5.0. With JVM support for accessing hardware-provided concurrency instructions (such as CAS) and the atomic variable classes provided in java.util.concurrent.atomic, it is now possible to develop highly scalable, wait-free, lock-free classes in Java.

Only 8 months before JavaPolis 2006 starts, so it's time to brain-storm about this years formula, content, tracks, new ideas etc.
Our kick-off meeting, organized at the Dolmen offices, often starts with some warm food (unfortunately not for me because I speak too much).
Just quickly looking at the pictures from last years kick-off meeting you can identify some patterns, do you notice them ?

The Steering members

For this years edition we've invited 2 new steering members; Guy Crets and Erwin Geirnaert.

Guy is managing partner of Apogado and has a main focus on Integration, that is why he'll be identifying speakers and topics in the messaging environment (SOA, EAI, ESB, etc). Last year Guy presented Secure and Reliable Web Services which brings us to our second new member...

Erwin is partner of Zion Security and as the name expects has an interesting focus on internet and application security. From that angle Erwin will identify some speakers and topics for the 2006 security track. Erwin spoke during JavaPolis 2004 on how to hack J2EE applications, you can check out his talk here.

We've another 2 months to finalize our JavaPolis 2006 theme.
This year, we would like open our JavaPolis theme for competition. So let your imagination go wild and send us your most creative visual and a headline in a viewable format to Valérie, the deadline is May 26th, 2006.
The theme winner will get a free 5-days entrance pass and will see his/her theme on all merchandising material of JavaPolis 2006.

Good luck!

The Tracks

We've also decided to rearrange some of the tracks, this is how it probably will be setup :

• Methodology, lead by Stephan Janssen
• Architecture, lead by Robin Mulkers and Jo Wyns
• Mobile, lead by David Delabassee
• Messaging, lead by Guy Crets
• Enterprise, lead by [~bst@jcs.be] and Hugo Brand
• Java Core, lead by Sven Beauprez
• RIA, Web, ... lead by Frederik Santens
• Hot Beans (Dyn. Languages, Real Time, ...) lead by David Delabassee
• Security, lead by Erwin Geirnaert

JavaPolis Survey

Looking at the official survey and comments received from our attendees, the above initiatives and changes will hopefully improve your overall Conference experience. If we now all bring our sister along we can also address the comment "We want more girls!!"

Agile development is a phrase that it appears no buzzword-compliant software development project can be without. However, it is a proper understanding of the motivation and practices, rather than the buzzword conformance, that makes the actual difference in development.

The concept of agility has differing (mis)interpretations and (ab)uses. Sometimes it is used as a synonym for Extreme Programming. By contrast, others use it to mean a generic notion of something that is not quite Extreme Programming, but may borrow ideas from it. Some developers may label a project agile just based on the occasional use of JUnit. Others may use the label to justify not writing any documentation or not agreeing to scope or delivery dates. To be fair, not all uses of the term are cynical or misguided, but the term has lost some of its potency through dilution.

This session begins by revisiting the motivation for agile development, and goes on to explore the wide-range perspectives that are encompassed by approaches that can claim to be agile, including both technical and non-technical aspects, the relationship between agility and architecture, the effect of skill and attitude, the role of organisation, and the support of practices and tools.
