Sounds like you want JNDI and Tomcat's startup functionality. I haven't done
this in Tomcat but it should be straightforward to instantiate some classes
on startup of Tomcat and reference them via JNDI. RTM.

>>Another issue: (similar to the one above): I have a result set, can I pass

You should probably convert your ResultSet to a detached rowset or a
Collection of data transfer objects. Make sure the objects are serializable
and you should be ok. Technically, I believe a java.sql.ResultSet
implementation would be serializable in the http session but that sounds
like a really bad idea since ResultSets represent open database cursors.
