I've been giving the project of upgrading our current JBOSS version from 2.4.4 to 4.0.x. Our current configuration uses servlets that use JDBC connections (a couple to a local MSSQL server, and one to an AS/400 using IBM Client Access).
In 2.4.4, jboss.jcml contains an entry for an XADataSourceLoader, that provides a DefaultDomain, DataSourceClass, PoolName, URL, etc. From what I've read, it appears that in 4.0.x, the database connections are done through defining DataSources, using -ds.xml files in deploy, and the appropriate jdbc.rar driver in lib.
What isn't clear (to me, as a beginner) is how the original PoolName, URL, etc. translates into a JNDI, etc., so that the servlet can still use the data connection w/o modification to the servlet. If that is even possible.
Can anyone point me to an example, or some documentation that spells out how this is done?
