The Java Specialists' Newsletter. Web-Harvest Project. Processing 1.0. Java. Esper: Event Stream Processing and Correlation. Published on ONJava.com ( See this if you're having trouble printing code examples by Thomas Bernhardt and Alexandre Vasseur 03/08/2007 Esper is an Event Stream Processing (ESP) and event correlation engine (CEP, Complex Event Processing).
Targeted to real-time Event Driven Architectures (EDA), Esper is capable of triggering custom actions written as Plain Old Java Objects (POJO) when event conditions occur among event streams. It is designed for high-volume event correlation where millions of events coming in would make it impossible to store them all to later query them using classical database architecture. Programming. Integrate external tools and builders in Eclipse. Before you start About this tutorial One of the nice things about an IDE is that you can do the majority of your development tasks in one application — hence, integrated.
It takes time away from your work to have to switch from your IDE to another program. The more often you have to switch among applications, the more you have, well, just a DE. That's not much of a step above a text editor. Using launch configurations in Eclipse Europa, you can run external programs from within the development environment. This tutorial introduces two main scenarios: One uses the venerable Apache Ant build tool that comes with Eclipse; the other is an example of a script that executes from within the IDE. Objectives In this tutorial, you learn how to build and use launch configurations. System requirements To get the most out of this tutorial, all you need is Eclipse Europa. And before you get started, add a new Java™ project to an Eclipse workspace and put at least one Java file in the project. Total Beginner Lessons. Introduction to Java Programming.

David Fischer's Java Programming Examples: Capture Video from Lo. This example program will capture the video and audio stream from a Logitech QuickCam Pro 3000 USB camera for 10 seconds and stores it on a file, named "testcam.avi".
You can later use the microsoft windows media player to display this file. 100% written in Java, using the media framework library (JMF) from Sun. Tested on Windows 2000. With some minor modifications, this programm will also work for any other USB cameras. Purpose / Benefits100% Java.Non Windows/GUI based program ->> command line utility.May be used together with a scheduler and a local webserver to publish periodically live video fragments on the internet.Easy sourcecode and easy to understand: you may make your own modifications in a short time.

Introduction to Programming in Java: An Interdisciplinary Approa. JavaSpecialistInauguralWebinar-2010-04-16_640x480.mov (video/qui. J-javaresources.html?ca=dgr-twtrJ-Resourcesdth-JV from ibm.com - Since its introduction to the programming community as a whole in 1995, the Java platform has evolved far beyond the "applets everywhere" vision that early Java pundits and evangelists imagined a Java world to be like.
Instead, the Java world rose up to Swing, coalesced around servlets, rode that into J2EE, stumbled on EJB, sidestepped over to Spring and Hibernate, added generics and became more dynamic, then functionalized, and continues to grow in all sorts of interesting directions even as I write this. Which leaves the Java programmer who didn't grow up along with the language somewhat overwhelmed. As a speaker, blogger, consultant, and mentor, I am frequently asked by junior and intermediate programmers working in the Java space for resources to help them master this wide, complex, seemingly endless world.
The response was enormous (for which I thank all those who replied). With no further ceremony, let us proceed. Web sites and developer Web portals The list of Web sites (with URLs):
