Hello everyone: I am currently assigned to test a big project which uses JRuby to build a web application. The reason of using JRuby is the web application is communicating with Java Service.

Sigh....I can not

Hi, I''m rather new to Ruby and RoR, so I do not really know whether this ist the right forum to place my question. For my first ''project'' I planned to create a simple online-viewer, which grabs data from an existing database and make them visible in a structured form via browsers.

However, the array-indexed block parameter is not something currently supported in JRuby: x = {} [1,2].each {|x[:foo]|} This is not used extensively in the Rails code, but it''s used enough to cause things to break in JRuby.
