+/**
+ * This implementation of <CODE>InitialContextFactory</CODE> should be used
+ * when ActiveMQ is used as WebSphere Generic JMS Provider. It is proved that it
+ * works on WebSphere 5.1. The reason for using this class is that custom
+ * property defined for Generic JMS Provider are passed to InitialContextFactory
+ * only if it begins with java.naming or javax.naming prefix. Additionaly
+ * provider url for the JMS provider can not contain ',' character that is
+ * necessary when the list of nodes is provided. So the role of this class is to
+ * transform properties before passing it to <CODE>ActiveMQInitialContextFactory</CODE>.
