Kurt, what does both your setter and getter code and method signatures
look like on CasesJdbcDAO when you're getting this error?
'javax.servlet.jsp.el.ELException: Attempt to coerce a value of type
"JDBCDataSource" to type "javax.sql.DataSource"' indicates an attempt
to inject a JDBCDataSource into a value binding expecting a
javax.sql.DataSource.
Something's not adding up here.
