I've recently started writing some performance tests in The Grinder 3, and one of the first things I noticed is that PyCheckMate doesn't work because it can't find some of the imports. Which editor(s) provide the best support for Jython?
As David Mentioned Pydev and even though it is a well developed piece of software I can't stand eclipse. Thankfully there are other choices. The latest version of Netbeans has jython / python www.netbeans.org and Komodo from activestate either the IDE or the free komodo edit
and pretty much any editor that supports python will give you some level of support for it but as far as a IDE built and designed for Jython... I think netbeans comes the closest otherwise the only reason to use the bloated behemoth called eclipse is because of pydev.
