Lucas Jellema

Performance of Enterprise Java Applications is a requirement and usually a challenge.

Creating reusable ADF Library with generic live resource bundle editing functionality and reusing it in any ADF application

Lucas Jellema 1

In previous articles, I have introduced functionality to centralize management of boilerplate text elements such as prompt, title, hint text and messages in resource bundles. This also allows for language or user group and other context sensitive values for these boilerplate text elements. The resource bundles, as was demonstrated, can […]

Supporting multiple languages in ADF applications backed by resource bundles – and programmatically controlling the JSF locale

Lucas Jellema 1

Any web application contains boiler plate text: text that is not part of the enterprise data from web services or databases that is manipulated by the end users using the application but that is part of the application definition itself. Text that is shown as prompt, title, message, hint text […]

Multiple production versions through WebLogic production redeployment

Lucas Jellema 1

Production redeployment is a facility in WebLogic that provides the ability to temporarily have multiple versions of the same web application of web service active at the same time. Sometimes, changes in application functionality require redeployment of the application. In the theoretical case of instantaneous responses from applications, we could […]

First steps with jWebSocket – open source Java framework for WebSockets – installation and running samples

Lucas Jellema 6

This month, In have been delving into Push architectures for the Web, looking into WebSockets among several other things.

WebSocket based interaction has lower overhead and – […]

Push based synchronized Slideshow demo application implemented using CometD and jQuery running on Tomcat

Lucas Jellema 2

In a string of recent articles, I have discussed downloading, installing and running demos for a number of different tools, frameworks and libraries that support push-style (web) applications in one way or another. I have looked into ‘classic’ comet with Grizzly, Atmosphere and CometD as well as ADF Active Data […]

Lucas Jellema 9

In the last few articles, I have discussed downloading, installing and running demos for a number of different tools, frameworks and libraries that support push-style (web) applications in one way or another. I have looked into ‘classic’ comet with Grizzly, Atmosphere and CometD as well as ADF Active Data Service […]

Getting Atmosphere – framework for Comet style communication – up and a first sample running on Tomcat

Lucas Jellema

Over the past weeks, I have been dabbling in Comet style, push-based, asynchronous communication enabling frameworks and libraries – including CometD, Atmosphere, Kaazing, jWebSocket, Grizzly and others. This short article will describe how I went about setting up Atmosphere on my local environment to the point that I could successfully […]

Preparing your environment for modern open source Java libraries and frameworks using Git and Maven, throwing in Tomcat as a bonus

Lucas Jellema 2

In my investigations into jWebWSockets, Kaazing, Atmosphere, CometD 2 and other frameworks I came to understand that in order to get these frameworks installed, integrate them into my custom applications or run the samples to go with these products, it would be convenient if not essential to have an environment […]

First experiences and getting started with GlassFish 3.1 and NetBeans 7.x – it's a breeze

Lucas Jellema 3

Several years back, AMIS selected GlassFish as its preferred Open Source J(2)EE Application Server, over for example JBoss. Some of the criteria at the time were: speed of implementation of new functionality and integration of JEE (being the reference implementatoin), ease of administration, enterprise quality, small yet rapidly growing market […]
