The following IDEs are supported. Versions numbers of the IDEs are those that JavaStyle has been tested on.
jEdit (4.1final and 4.2pre5) - good support in latest version of JavaStyle.
Netbeans (3.5.1) - partial support, but not yet fully integrated.
JBuilder 9 - partial support, but not yet fully integrated
Ant (1.5.4) - pretty printing only
Stand-alone application - works well but has very limited editing support, its more a demonstration than anything else.
The next release will support more IDEs, and give a higher level of integration for them. Support for Eclipse, InteliJ and Emacs JDE has been requested. Note: there is partial support for several other IDEs in CVS (Cafe, elixir, jDeveloper, jooda and kawa)
