JRuby. :-)

One possible case where you need to write Java code: you might want to
use Java libraries which do not work nicely with the (J)Ruby way and
have to create glue code.

Other than that some "low level" things might be more efficiently done in Java.

A different option is to use a Java framework (e.g. JEE) and use JRuby
callouts to customize business logic.

Go for JRuby - at least give it a try.
