The javadesktop.org Swing Component Depot column has a backlog of more than 50 component suites. They'll all appear there eventually however we thought you'd like to see the queue now, in all its unadorned glory. So, here for your delectation is a brief summary of all 50+ of them.

I appreciated the comments in response to the original version of this blog ("Another 40 Swing Component Libraries") that have appeared here on javadesktop.org and on JavaLobby.org, particularly the many suggestions about libraries that deserved to be added to the list. Some of the feedback pointed out that it wasn't entirely clear where I was drawing the line, not every library listed here was a Swing Component suite. I have to admit that didn't religously hew to that line. Looking at web sites devoted to Swing component suites often lead to products that were relevant to Swing app developers like spell checkers, PDF generators, and so on. A few of these have made it into the list because I couldn't help but inadvertantly vacuum them up in the process of collecting vital statistics about mainline Swing component libraries. In this update I've added another 14 libraries to the list, nearly all of the ones suggested by people who've offered feedback:

• jProductivity - Components!
• UICompiler
• Einnovations EII Commons
• Gandalf Wizard Framework
• Zeus Components Library
• JBalloonTooltip
• Hypergraph
• JForm
• Foxtrot
• Kiwi
• Geosoft G
• StarLink
• Inxight Software
• Thinkmap

One suggestion that led to to a few extra entries that probably don't, strictly speaking, belong was Hypergraph. Hypergraph is an impressive open source project that has produced a J2SE component for visualizing hyperbolic trees. There are several commercial projects in this space: Inxight, Thinkmap, and TheBrain.com. All of these products provide applet viewers for hyperbolic trees and all of them have eye-popping demos on their respective web sites (go ahead and look, you will not be disappointed). Both Inxight and Thinkmap provide SDKs, however based on my cursory look at their sites, the SDKs are for server side work or they're custom JDK1.1 viewers based on AWT. In fact I didn't list TheBrain.com at all, despite the inspiring name, since there didn't appear to be a Java SDK there at all. Still it didn't seem right not mention them since they're great examples of what desktop Java is capable of and they could probably become part of a modern Swing application. Plus, the Hypergraph site provided pointers to all of them and I just couldn't stop myself.

Warning: in many cases I've lifted or crudely paraphrased vendor product descriptions in the list below, rather than craft my own pithy summary. It's not because I'm incapable of doing a good job of that, it's because I'm lazy and life is short. It's also worth pointing out that I'm not trying promote the relative merits of these packages, just their existence.

There are more than 50 entries in the list below and that's more than the most devoted fan of Swing component libraries is going to want to sift through. I've attempted to break the entries into categories to ease the burden a bit: General Purpose, Database, Graphs and Charts, Special Purpose (for physics, astronomy, oil exploration, etc, components look here first), Calendars, and "More". Naturally not every library fits nicely into one of these categories, for example nearly every general purpose library contains calendar or database parts. The "More" category contains libraries that didn't fit into a category. There are two (obvious) additional categories that are missing because they're big enough to deserve their own roll-up: layout managers and look and feels. Those categories will have to wait until a future blog; I've got blisters on my fingers.

A Java Swing library for creating configurable menus, toolbars and popups. Applications built with Configure can be reconfigured by end-users through direct manipulation of the GUI itself.

JAPISoft

JAPISoft provides everything from EditX, v an XML Editor and XSLT Debugger, to most of the components you'd need to build a software engineering tool, like an IDE. Among the Swing parts you'll find on the site are JXMLPad, a Swing component/framework for editing XML/XHTML documents, JDock, a Swing framework for MDI applications that is compatible with standard layout managers, and JResourceBrowser a generalization of JFileChooser. Most of the software is vailable for free evaluation and the sites, www.JAPISoft.com and www.SwingAll.com, are packed with screenshots.

Infragistics - JSuite

• ICEreader SDK enables developers to render static HTML/XML content in applications where secure or dynamic Web capabilities are not required.
• ICEpdf SDK can be used as a standalone PDF document viewer application, an embeddable PDF viewer component, or combined with ICEbrowser SDK for a complete web-content rendering solution.

Javaio - WebWindow, Component Suite, JModeler

Loads of very high level parts here, beginning with the WebWindow browser component. WebWindow is a small pure Java HTML viewer that's intended to take up the slack from Swing's JEditorPane. JModeler is a generic diagram editor for building modeling applications and the Javaio Component Suite includes components like JOutlookBar (this sort of thing is sometimes called an "accordion" control), JHelpView for JavaHelp, and JSlidePanel for animating panels in and out of view.
