Okay.. We're almost there, but the env.lookup("yourconnection") bit is the
key that is specified in config.xml 'right?'
<data-source key="yourconnection">
Doesn't work like this it throws an exception.... It tells be yourname is
not bound in this context...
While I'm sure , in fact i know there's a good reason for this, I usually
prefer to enrich my understanding after something is running....
Prehaps i should try denistry rather than becoming a dustman..
Many thanks mark
