The code is placing JDBC information into a hash table and passing it to the InitialContext. I believe that since the code is running within the app server that there is no need to pass any properties to InitialContext. As an aside, if the code did need to provide properties to InitialContext it would be JNDI properties, not JDBC properties. Also, if this suggestion doesn't fix the problem, post the error you are getting. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3967367#...
