javax.faces.FacesException: com.ibm.websphere.ce.cm.ObjectClosedException: DSRA9110E: ResultSet is closed

Hi, I'm developing a Web App using RAD 6.0 (Eclipse) and an IBM
Websphere Application Server. My application creates reports on a
database that has records added to it every minute. When a button is
clicked the first time, the application runs correctly and retrieves
the count of the number of records in the table that have been added
on the current date grouped by the Origin and Transaction type. The
problem occurs when I click the button again to refresh the count; I
encounter the "javax.faces.FacesException:
com.ibm.websphere.ce.cm.ObjectClosedException: DSRA9110E: ResultSet is
closed." I think the problem occurs because the connection object is
trying to get re-used after it has been closed instead of being re-
created. Can anyone help me find out what's wrong and how to fix it?
Here's my code so you can understand better.

public DataSource getDataSource() throws SQLException {
try {
    javax.naming.InitialContext ctx = new InitialContext();
    ds = (javax.sql.DataSource)ctx.lookup("jdbc/IBXMonitor_Con1");
} catch (NamingException e){
    e.getMessage();
}
return ds;
}

public void loadTable(){
PreparedStatement runSummaryQuery;
String SummaryQuery = "SELECT TRX_TYPE, ORIG_CD, COUNT(*) As
RQSTCOUNT"
+ " FROM IBX.TRACK"
+ " WHERE RQST_TM > " + "'" + BeginningTM() + "'"
+ " AND RQST_TM < " + "'" + CurrentTM() + "'"
+ " GROUP BY TRX_TYPE, ORIG_CD";

try {

    Connection con1 = getDataSource().getConnection("user", "pswd");
    runSummaryQuery = con1.prepareStatement(SummaryQuery,
ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
    ResultSet rs = runSummaryQuery.executeQuery();
    rs.beforeFirst();
    tblSummary = getTblSummary();
    tblSummary.setRendered(true);
    // Display results in table
    while (rs.next()) {
        tblSummary.setValue(rs);
    }
    con1 == null
} catch (SQLException e) {
    e.printStackTrace();
} catch (Exception e) {
    e.printStackTrace();
}
}

The button on the jsp page simply calls the loadTable() method. If you
need anymore information such as the stack trace I'll be willing to
post it up.

Thanks,
Tim
