Fix ant task Wscompile cannot be found in NB 6

The bug seems to be in /nbproject/project.properties:
Change:
wscompile.classpath=${wscompile.tools.classpath}:${j2ee.platform.wscompile.classpath}
To:
wscompile.classpath=${wscompile.tools.classpath}:${j2ee.platform.wscompile.classpath}:${javac.classpath}

Jruby warble calendar_date_select

If you are trying to pack up a jruby rails app that uses calender_date_select.

and you get undefined method 'calendar_date_select_includes'

remember to add public to your directorys in your warble.rb file.

Took me ages to figure out that this was the problem

Jruby warble tomcat RoutingError

Took me while to figure this one out you need to add

config.action_controller.relative_url_root = '/{appname}'

to environments/production.rb

or environments/development.rb
