create recordset from jdbc datasource

I'm accessing data in jsp page using the following code.

<sql:query var="result" dataSource="jdbc/ums">
                    SELECT *  FROM ums_memory
</sql:query>

Now, I want to access the records using a recordset object like in ASP, so as its more flexible to process the records.

Is it possible to create a recordset object from datasource "jdbc/ums" ?
