APACHE JAKARTA COMMONS REVIEW
**************************************************
TOPIC:
Apache Jakarta Commons Review: Commons Net
ABSTRACT:
Each meeting we will take 30 minutes to do a quick presentation on one of the Jakarta Commons projects. These projects are numerous and very useful but most people do not know the breadth of what is available. In this short presentation we will overview what the project is and what it is useful for. We will also share some simple code snippets of how to use the project. This presentation will cover Commons Net.
Apache Commons Net implements the client side of many basic Internet protocols. The purpose of the library is to provide fundamental protocol access, not higher-level abstractions. Therefore, some of the design violates object-oriented design principles. Our philosophy is to make the global functionality of a protocol accessible (e.g., TFTP send file and receive file) when possible, but also provide access to the fundamental protocols where applicable so that the programmer may construct his own custom implementations (e.g, the TFTP packet classes and the TFTP packet send and receive methods are exposed).

TOPIC:
Google Collections Library
ABSTRACT:
The Google Team has build a collections library that goes beyond the capabilities offered in Apache Commons Collections with some of the most intuitive object interfaces you've ever seen on a third party library. Unlike Commons Collections, the Google Collection Library uses the full capability of the Java 5 Generics and faithfully adheres to the JDK interfaces they implement. The authors of this library suggest you grab a few of these implementations and integrate them into your app for better (Google-like) performance with large collections.

TOPIC:
Unlocking Your Application's Ability To Scale
ABSTRACT:
You and your team are writing excellent code, following many best practices, and have excellent JUnit tests around your modules. Bug count is low, customer satisfaction is gaining momentum. And you are about to be eaten alive by your own success because your application can't scale to the 100,000 users now simultaneously accessing your system... This presentation will offer some practical from-the-field advice in a Java and Language Neutral fashion on how to build or adjust your system to scale to dramatic numbers of users. We'll follow up with a hands-on demo of a distributed processing system (if the wireless hardware setup is successful in our meeting room), with the note-book-bringing attendees of the meeting participating in the processing (client JARs to be sent to attendees on the day of the meeting).

June 2007 Meeting
MEETING:
Join us in the Denver Tech Center on Thursday, June 21st, for our monthly meeting where Dean Hiller will speak about the tool, VerifyDesign.
AGENDA:
5:30-6 p.m. Food and Networking (Free Pizza!)
6-7:30 p.m. Main Meeting
TOPIC:
Using VerifyDesign
ABSTRACT:
VerifyDesign is an Ant Task and package dependency analyzer that verifies a project's source code matches the application design. Verifydesign lets you codify a design in XML and run compile-time checks to notify developers of dependencies that break the design specifications. It can be considered an agile-enabling tool that facilitates better (conforming) coding results. VerifyDesign is used by SourceForge projects such as javasm, javasip, mocklib, and channelmanager. Come hear how this tool can be effectively applied to your latest project.
SPEAKER BIO:
Dean Hiller loves to code, design, and refactor. He spends much time in open source and has worked on the following open source projects: mocklib, verifydesign, channelmanager, javasip, and javasm. Dean is currently the Director of Architecture at Carrier Access.
May 2007 Meeting
MEETING:
Join us in the Denver Tech Center on Thursday, May 17th, for our monthly meeting where Scott Ryan will speak about Lesser Known Features of Maven 2.
TOPIC:
Lesser Known Features of Maven 2
ABSTRACT:
Maven has been around a few years and recently upgraded to version 2. Maven has its supporters and its detractors and both are well deserved however if one takes the time to understand the power of Maven and what it is good at it may surprise you how powerful a tool it is. Coined as a build tool to replace Ant the real power of Maven has been lost by many. Recently retooled around the plexus container with less tight integration Maven has a new life and is seeing a big uptake in the development world. In this talk we will explore some of the lesser known features of Maven. In the past I have talked about the build capabilities of Maven and how to construct maven plugins to extend Maven functionality. In this talk we will discuss some other features that can make you a hero during audits and make management feel more comfortable when the evil SOX word is brought up.
The Maven Repository - We will talk about how it is organized and how you can use the repository even with your Ant based builds to help maintain a clean audit trail to your artifact usage. We will also discuss Enterprise repositories and an open source project called Archiva that allows you to secure your repositories as well as proxy them out to the internet for greater reach and control over your artifacts.
Documentation - While this is always a dreaded task by any developer it is a necessary evil during audit time. If you expect any sort of reuse you must offer well organized and current documentation for any toolkits or frameworks you expect people to use.
Automated Builds - One thing that Maven offers is a predictable project structure. While many people view the structure as rigid it is actually quite flexible. With a simple set of xml files you can describe any project setup. By leveraging this project definition plugin developers and automated build tools can absorb and process maven projects with very little configuration.
Release Management - One tedious task is producing releases and release definitions for the SCM team. We will explore the tools that Maven offers to make release management a snap.
What the heck is in that EAR? Maven offers some tools and configuration files that are included with each artifact that allow you to discover many attributes about the artifact during runtime.

April 2007 Meeting
This meeting will occur on April 19,2007
TOPIC:
JUnit 4 and Eclipse Testing Plugins
ABSTRACT:
Just about every Java developer has used JUnit up to version 3.8 at some point in their career but the JUnit 3.x series is showing its age. The JUnit authors took all the feedback gathered up to version 3 and designed JUnit 4 from the ground up.
Making full use of Java 5 annotations and adding powerful new exception testing, life-cycle startup methods, and suite setup, JUnit 4 truly has had a great makeover. It is now easier to use than ever and makes test-first coding a very rewarding practice. Along with live coding demos of JUnit 4 throughout the session, useful supplementary Eclipse Testing Plugins will be showcased.
