Statement Closed Error

Question

Hi Friends,
I have two queries to run from one class.I send the queries to another class,which send me back the resultset to cook.For one query its running fine,but i don't know why for two queries ,its throwing error as "statement closed".Can you please tell me where i am going wrong???
In first method i have:
ResSet qt = new ResSet();
ResultSet rs=qt.getResultSet(query);
2nd method:
ResSet qt1 = new ResSet();
ResultSet rs1=qt1.getResultSet(query1);
public class ResSet
  private Connection con;
  private Statement st;
  ResultSet results;
  private DataSource ds;
  int count = 0;
public void getResults()
    try{
      Context init = new InitialContext();
       if(init == null )
          throw new Exception("No Context");
       Context ctx = (Context) init.lookup("java:comp/env");
       ds = (DataSource) ctx.lookup("jdbc/con");
       con.close();
      }catch(Exception e){e.printStackTrace();}
public ResultSet getResultSet(String Query)throws Exception
   if (ds != null) {
     con = ds.getConnection();
     if (con != null) {
       st = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
                                ResultSet.CONCUR_READ_ONLY);
   results = st.executeQuery(Query);
   return results;
public void close()
  try { results.close(); } catch (Exception ex) {}
  try { st.close(); } catch (Exception ex) {}
  try { con.close(); } catch (Exception ex) {}
}

No,I am calling close() after I display the results in my jsp,that's the end line of my project.I even tried commenting it,but that didn't worked either.Please help me..cause i have no clue where i am goin wrong.
