Please tell me if it is possible to do the following: create an instance of a specific class in Java pass it to JRuby to do something with it continue using the "modified" version in Java May you provide a small working example? EDIT: It turns out that embedding was the simplest way to achieve this. More information is available on Embedding JRuby .

Please tell me if it is possible to do the following:

create an instance of a specific class in Java
pass it to JRuby to do something with it
continue using the "modified" version in Java

May you provide a small working example?

It depends on what you mean by "do something". If you mean "redefine a method", then the answer is no, not really. The new method will be used by jruby, but any calls to the method in java will continue to invoke the old method.
