Can't debug Ruby on Rails application in Netbeans 6.8

Question

Every time I try to debug my Rails app via Netbeans I get a ...

"Could not connect to web server - cannot show http://localhost:3000"

Rails - 2.3.5 Ruby - 1.8.7-p249

Anyone know how to resolve this?

Thanks

Answer 1

Have you checked your ruby platform? If I remember rightly when you install a new version of Netbeans it can set the default to JRuby. In 6.5.1 at least you'll find it under Tools->Ruby Platforms.

Answer 2

Had to downgrade the ruby-debug-ide gem to 0.4.7.
