Eclipse.org has released a new plug-in – the JDoc Editor. The WYSIWYG is seamlessly linked to the active JDT editor. It provides a useful complement of word processing styled functions appropriate for composing and revising JavaDoc content with realtime production of HTML styled JavaDoc content. New features in the release include:

• Support for Eclipse 3.2
• Initial support for JavaDoc repair tags
• A real-time spelling checker for JavaDoc text.
• Support for bidirectionally linked, realtime editing of JavaDoc content
• New JavaDoc comment blocks generated automatically from the right-click menu
  Class, constructor, and method signature types hyperlinked to the full JavaDoc pages. JDocEditor has automatic access to the Eclipse platform JavaDoc and can be configured to transparently access any JavaDoc repository, local or remote, such as JDocs, and present the JavaDoc pages in the platform help browser

The JDoc Editor plug-in requires Eclipse 3.2 and JDK 1.5+.  It was developed on Windows with limited testing on other platforms.
