SwingWT is a 100% pure Java library which aims to be a free implementation of Swing and AWT. Unlike Swing, SwingWT drives native peer widgets for your platform from SWT. You can see a screenshot of the basic SwingWT demo here (Linux/GTK2) and here (MacOSX).
Main features:
- More responsive GUIs and faster startup times
- Less RAM usage for applications
- Many developers prefer the Swing API
- Existing Swing applications dont need to be recoded
- Mature Swing UI designers can be used
- Developers deploying to *nix/Win32 can compile natively with GCJ and the applications can be distributed without a VM. Linux distribution makers could package many existing Java/Swing applications that previously could not be distributed in workable state.
- SWT components can be directly accessed through the API, allowing mix and match (make Eclipse plugins with Swing!)
- All platform benefits such as font sub-pixel decimation for LCD monitors (unavailable in Swing)
- Use Swing on mobile devices!
- The best of both worlds! New Swing components for JClosableTabbedPane, JCoolBar, JTaskTrayItem..
- A FREE implementation of Swing you can redistribute and modify to suit your own requirements
- Insulation from changes to the SWT APIs
- Insulation from differences between SWT platforms
Enhancements:
- This release contains many fixes and compatibility improvements, including support for AudioClip and SWT 3.2.

Applications that collect data from RSS-compliant sites are called RSS readers or "aggregators" RSSOwl is such an application.
RSSOwl lets you gather, organize, update, and store information from any compliant source in a convenient, easy to use interface, save selected information in various formats for offline viewing and sharing, and much more.
Its easy to configure, available in many many languages and the best of all: Its platform-independent.
RSS ("Really Simple Syndication" or "Rich Site Summary") is a document specification that gives users the power to collect and organize Web-based news and information in a more efficient manner.
The owl is a traditional symbol of wisdom, and a quiet, efficient hunter. Youll find RSSOwls "big eyes" a big help when scanning the Webs vast array of RSS sources.
Main features:
- Import your favorite newsfeeds using the OPML format. Most newsreaders support the export of newsfeeds via OPML, making it very easy to switch to RSSOwl and have your bookmarked favorites inside RSSOwl.
- Bookmark your favorite newsfeeds in nested categories. Set properties like "auto-update-interval", "open on startup" or "reload on startup".
- RSSOwl helps you finding a suitable title for your favorites. Just click the "Grab title from newsfeed" button and RSSOwl will scan the newsfeed for the title and use it for the new favorite.
- Create collections of newsfeeds other may subscribe to. A subscription is a file that contains newsfeeds. Placing the subscription online will allow others to subscribe to that collection and have the same newsfeeds inside RSSOwl. The subscription is updated each time RSSOwl is starting.
- Switch on the internal browser to read news that contain HTML. Some newsfeeds use this kind of technique to include images and links.
- Select a newsfeed, a single news or an entire category of newsfeeds to export the content into one of the formats PDF, RTF or HTML. When exporting news into PDF, RSSOwl will create bookmarks showing the titles of all news. These are very helpfull when searching for a particular news inside the PDF document.
- RSSOwls internal panels are highly customizable. Choose between a 2-column and a 3-column layout. Hide and restore the tree containing all favorites and the quickview box. Maximize the tabfolder with a single click in order to view a website inside the internal browser with full size.
- A lot of search-options make RSSOwl a powerful application to search inside a newsfeed or an entire category. The boolean operators "and", "or" and "not" may be combined with the search-term. Common options to only match a whole word, regard case-sensitivity or to use regular expressions are allowed. Results are displayed in the tabfolder and each keyword is highlighted inside the newstext.
- AmphetaRate is a centralized ratings/recommendation service that provides personalized news and blog recommendations. Each news found in your subscribed feeds may be rated "Fantastic", "Good", "Moderate", "Bad" and "Very bad". Your recommendations are computed by Bayesian filtering and an algorithm finding people who share your taste.
- The integrated newsfeed-search engine allows to search for newsfeeds by keyword. Simply enter words like "News" or "Linux" and press the search button. Soon the engine will give out a list of newsfeeds. It is also possible to restrict the search to only match newsfeeds that have the same language that RSSOwl has set. Once the search has finished, import all of them into any category with a single click.
- Tired of copying and pasting newsfeeds out of a website into your newsreader? Simply enter the website containing links to newsfeeds into the feed-discovery and RSSOwl will show all the newsfeeds it has found. Import them into any category with a single click. Or enter the URL to an OPML file and gain access to its newsfeeds - its a breeze!
- The integrated feedvalidator allows to check the validity of a newsfeed. Any error or warning is shown inside the validator, together with the line-number. This feature makes the perfect tool for bloggers as theyre able to test their newsfeeds. RSSOwl provides support for RSS 0.91, 0.92 and 2.0 straight "out of the box".
- Access password protected newsfeeds. RSSOwl 1.0 is supporting the Base authentication which is the original and most compatible authentication scheme. But be prepared for RSSOwl 1.1 coming soon which will also support Digest and NTLM authentication that was introduced with HTTP 1.1.
- A small toolbar above the tree containing all favorites allowes to execute the commands "Reload All Favorites", "Aggregate All Favorites", "Search in all Favorites" and "Mark All Favorites Read". Believe us, its a handy feature. :-)
- Place RSSOwl into the system tray on minimization. As soon as RSSOwl is reloading a newsfeed and detects that new, unread news are available it will tell you so.
- RSSOwl is highly customizable. "Preferences" allow to change fonts, languages, colors, hotkeys and a lot more. Export settings into a file to import them into RSSOwl on a different computer. Switch fonts or make yourself comfortable with RSSOwl by choosing one of the 25 languages available - everything is just a few clicks away!

WebCharts 3 allows you to deliver general purpose and specialized 2- and 3-dimensional charts as applets or interactive server-generated images (PNG, GIF, JPEG, SWF, SVG, PDF, TIFF, and WBMP) to Web browsers and mobile devices, or embed charts into stand-alone Swing/SWT applications.
WebCharts3D includes a WYSIWYG (What You See Is What You Get) designer that can be easily incorporated into your own applications to provide your end-users with chart editing capabilities. Full JSF support is included.
Enhancements:
- This version offers many enhancements including new chart attributes such as line and curve strokes and error bars, new maps, and improved gauges.
- It also provides a full-featured plugin for Eclipse that can be used instead of WebCharts3D Designer and offers XML, Java, and JSF/JSP/Swing/SWT code generation capabilities along with browser-based chart preview.
- The product now supports two additional formats - VML (Vector Markup Language) and CANVAS tag, which allow it to render the charts directly as vector graphics inside the browsers instead of using image generation.

wx4j project is a Java binding for wxWindows.

It provides a Java GUI toolkit using native widgets (to utilize the native look and feel).

This is in contrast to Swing/JFC which tries to mimic the native look and feel, but usually doesnt quite feel right. In this respect, it is very similar to the SWT toolkit used in IBMs Eclipse IDE. But rather than inventing yet another toolkit, wx4j utilizes the proven wxWidgets C++ library and uses SWIG to expose the API in Java. This also means the event loop executes in C++ and is very responsive.
