#12 JMS and JNDI

[David A Durrant]

Change all the current JMS connectors for the different
providers that have been connected to remove any
references to the specific TopicConnectionFactory
classes that are used for those implementations. The
existince of the classes in the code is causing
problems for deployment and compiling. If JNDI is used
for the connections, then the hard refs to the class
names can be removed and Class.forName() methods
could be used instead.
