HOWTO: Use the Spring data access methods together with the WebRowSet class

Question

With the WebRowSet class I can easily iterate over a ResultSet and produce some XML using the code below.
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection connection
= DriverManager.getConnection("");
Statement statement = connection.createStatement();
ResultSet resultSet = statement.executeQuery("SELECT SYSDATE FROM DUAL");
WebRowSet webRowSet = new WebRowSetImpl();
webRowSet.populate(resultSet);
statement.close();
connection.close();
webRowSet.writeXml(new FileOutputStream("C:\\SYSDATE.xml"));
So, how would I use the simplified Spring methods to do the same thing? The WebRowSet.populate method only supports a ResultSet object. The Spring framework only returns an SqlRowSet object that is not easily cast to the ResultSet, etc.
Thanks for your help.

Cast Spring's SqlRowSet to ResultSet? Impossible. It's an interface that does not extend java.sql.ResultSet.
javax.sql.WebRowSet is an interface that extends java.sql.ResultSet.
Spring does have a concrete class ResultSetWrappingSqlRowSet whose constructor can take a java.sql.ResultSet.
So I think your solution is to instantiate a new ResultSetWrappingSqlRowSet, passing it your javax.sql.rowset.WebRowSet, and return that wherever Spring wants to return a SqlRowSet.
