Swing-XML Authoring Tool

Thanks for this guide, I tryed to implement this idea but I have troubles in step 5

My JDBCDataSource is like this:

package es.test.swixat.databinding;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import org.apache.commons.jxpath.JXPathContext;
import org.swixat.SwiXAT;
import org.swixat.databinding.AbstractDataSource;

public class JDBCDataSource extends AbstractDataSource
{
private String connectionJDBC;
private String query;

/** Creates a new instance of JDBCDataSource */
public JDBCDataSource ()
{
super();
}

public String getConnectionJDBC ()
{
return connectionJDBC;
}

public void setConnectionJDBC (String connectionJDBC)
{
this.connectionJDBC = connectionJDBC;
}

public String getQuery ()
{
return query;
}

public void setQuery (String query)
{
this.query = query;
}

protected Object extractData(JXPathContext sharedContext)
{
Object connection = SwiXAT.getFactory().getBean(getConnectionJDBC());
Object query = SwiXAT.getFactory().getBean(getQuery());
Connection con=null;
Statement stmt=null;
ResultSet rs=null;

try
{
Class.forName("com.mysql.jdbc.Driver");
}
catch(java.lang.ClassNotFoundException e)
{
System.err.print("ClassNotFoundException: ");
System.err.println(e.getMessage());
}

try
{
con = DriverManager.getConnection((String)connection, "user", "password");
stmt = con.createStatement();
rs = stmt.executeQuery((String)query);
while(rs.next())
{
System.out.println(rs.getString("id")+"\t"+rs.getString("texto"));
}
rs.first ();
}
catch(SQLException ex)
{
System.err.println("SQLException: " + ex.getMessage());
}
return getPropertyValue(rs, sharedContext);
}

}

Everything compiles well and runs, the only problem is the value of texto doesn´t appeared. The connection to Mysql is well because the line "System.out.println(rs.getString("id")+"\t"+rs.getString("texto"));" prints the info I want to show in textField.-

Any suggestion?

Thanks in advance.
