This artifact provides a single jar that contains all classes required to use remote Jakarta Enterprise Beans and Jakarta Messaging, including all dependencies. It is intended for use by those not using maven, maven users should just import the Jakarta Enterprise Beans and Jakarta Messaging BOM's instead (shaded JAR's cause lots of problems with maven, as it is very easy to inadvertently end up with different versions on classes on the class path).

There is a newer version: 35.0.0.Beta1

This package contains implementations of the
{@link org.apache.commons.collections.BidiMap BidiMap},
{@link org.apache.commons.collections.OrderedBidiMap OrderedBidiMap} and 
{@link org.apache.commons.collections.SortedBidiMap SortedBidiMap} interfaces.
A BidiMap is an extension to Map that allows keys and values to be looked up with equal ease.
One example usage is a system communicating to a legacy datasource that must convert codes
from the new format to the old format and vice versa.

The following implementations are provided in the package:

DualHashBidiMap - uses two HashMaps to implement BidiMap
DualTreeBidiMap - uses two TreeMaps to implement SortedBidiMap
TreeBidiMap - red-black tree implementation of OrderedBidiMap


The following decorators are provided in the package:

Unmodifiable - ensures the map cannot be altered
