You set up a session/request attribute from the Java code.
However, I would suggest not using a ResultSet, as it has some lifecycle issues (i.e. needs to be closed). I would suggest fetching the ResultSet object in the Java code, iterating over it building, say a List, closing the ResultSet and pass the List to the JSP.
If you are using Spring, the JdbcTemplates provide methods that take an SQL string and parameters and return a List> with the results of the query, which might come in very handy for this.
