JXSE and Equinox Tutorial, Part 3: Introducing the JP2P Container

 Abstract

  • It has been a while since the first and second posts of this series, but a lot has happened in the past few months, most notably the fact that the code from eclipselabs is going to be ported to Project Chaupal which will (eventually) be(come) the OSGI implementation of the JXTA specs. As a result, I decided to rename the packages and make the architecture as clean as possible prior to the change.

    • This tutorial will cover some of the features which are already available, and can help to make the development of JXTA applications in Eclipse/Equinox a bit easier.

JXSE and Equinox Tutorial, Part 2

JXSE and Equinox Tutorial, Part 2


NOTE: As of January 2015, you can integrate JXTA in OSGI through an update site. The WIKI  At chaupal.org  gives detailed instructions on how to use the new 2.8.x JXSE bundles for OSGI.Many of the features covered here are implemented by default.

Abstract

In the first post of this series, we covered the quickest way to get JXSE 2.7x working in Equinox and, with some considerations, probably other OSGI frameworks as well. The approach aimed to get the same functionality as you would get by using the jar file in a regular JAVA setting, but as I demonstrated, Equinox does have the benefit of allowing multiple JXSE instances to run simultaneously, which is a great benefit when developing JXSE applications.

In this second tutorial, we will cover some ways of improving the functionality by severing the dependency on the 4.2x version of Jetty (which has just released it's 9.0 version!) and we will introduce some basic tools to visualize the properties and functions of JXSE. This will improve the development cycle of JXSE applications even more.

JXSE and Equinox Tutorial, Part 1

Abstract

NOTE: As of January 2015, you can integrate JXTA in OSGI through an update site. The WIKI  At chaupal.org  gives detailed instructions on how to use the new 2.8.x JXSE bundles for OSGI.

This extended series of tutorials will cover the various ways that the JAVA P2P framework JXSE (formerly popularly known as JXTA, and currently the most up-to-date JAVA implementation of the JXTA specifications) can be made to work with Equinox (the engine on which Eclipse runs). It would be tempting to replace Equinox with OSGI, and indeed many of the issues covered here will work fine with alternative OSGI implementations such as Apache Felix or Knopflerfish, but I will concentrate on Equinox because it will allow us to do a few things with JXSE that requires a bit more handwork on other OSGI platforms. Besides this, I have tested the code on Equinox alone, so I don't want to get ahead of myself. This tutorial is work in progress, so the document will be re-edited a few times.

This tutorial not meant to cover the principles behind P2P in general, and JXTA/JXSE in particular. If you are interested in this, I'd recommend the (free) book Practical Jxta II by Jérôme Verstrynge, or to go through the online manuals for JXTA 2.5, JXSE 2.6 and 2.7. This first tutorial is aimed to get you started with JXSE 2.7x in an Equinox environment. The reader is expected to have a good understanding on developing plugins with the Eclipse IDE. If you are new to Eclipse I would advise you to read the excellent articles on developing plugins by Lars Vogel and brush up on OSGI and Equinox while you're at it.

JFXtras RadialMenu for NetBeans RCP (Part 2)

this article is part 2 of a tutorial that will walk through adapting an open source javafx radialmenu (  http://jfxtras.org/  ) to replace the netbeans platform system menu.  it will build upon both previous tutorials and  part 1  that demonstrate complete replacements for the default netbeans swing components using javafx.  code examples will feature netbeans platform, javafx and css.

part 1  of the article walks through some of the code upgrades necessary for the task.  as of this article’s writing the open-source jfxtras radialmenu needed a few upgrades to act as a system menu replacement for a netbeans platform rcp.  part 2 will show the specific algorithm and code to then utilize the upgraded radialmenu as described.  when complete you should be able to produce a slick radial system menu like this:
