Have you ever heard about SwingX??

Of corse you have!
SwingX is a set of components intended to extends functionalities of Swing API default.
Let see how integrate a set of components to the Netbeans' Pallet 5.5 beta, but you can do it from 5.0 version.

To do it, click right button over Pallet and select 'Pallet Manager', make a new category (New Category) that you can call as "SwingX" and add SwingX jar (Add from JAR).
Now we need say wich classes will be added to the Pallet. These classes are:
JXCollapsiblePane , JXComboBox, JXDatePicker, JXDialog, JXEditorPane, JXErrorDialog, JXFindBar, JXFindPanel, JXGlassBox, JXHyperlink, JXImagePanel, JXList, JXLoginPanel, JXMonthView, JXPanel, JXRadioGroup, JXRootPane, JXSearchPanel, JXStatusBar, JXTable, JXTableHeader, JXTaskPane, JXTipOfTheDay, JXTitledPanel, JXTree, LabelProperties

Note: These classes are of SwingX API stable, the development API has some extras components.



After some "nexts", we have the SwingX components integrated with our NetBeans :). You can add these components without problems into of JFrame or JPanel.

Take a look at the Pallet of SwingX into NetBeans!

Release 0.1 added for Spring Framework Netbeans module

My partner of JavaFree, Marcos Silva, has written about Netbeans plugin support to Spring Framework.
I haven't already used it, and it seems that is still in development (0.1 version).
Summary:

An early release of a module providing Netbeans integration with the Spring Framework has been released. The module allows users to select select the Spring Framework when creating web applications in Netbeans. The module will then add the necessary libraries, configure spring in the web.xml, and register an XML Catalog in the netbeans runtime tab. This will enable XML code completion when editing Spring Framework beans configuration files.
