#jrequire(qualified_class_name) ⇒ Object

Maps the packages and class name specified by qualified_class_name to a nested set of Ruby modules. The first letter of each module name is capitalized. For example, java.util.HashMap would become Java::Util::HashMap.

The first use of jrequire will render all subsequent calls to require_jar ineffective.
