Passing parameters to a Crystal Reports JavaBean connection

Question

Hi,
I'm trying to pass a parameter to a CR XI JavaBean connection. So far I can read and show a String parameter in the report, but I'm unable to pass it to the getResultSet(String aParameter) method that provides the ResultSet.
The Crystal Reports editor shows a dialog box asking for the "Parameter 1". I've tried with the parameter name and with an arbitrary value, but it just doesn't work.
Any comment from anyone who has been able to figure this out would be really welcome. The Crystal Reports documentation isn't very useful.
Best regards,

I'm about to throw Crystal Reports thru the window. There is no documentation, their knowledge base is a wasteland, the samples included are just the simplest ones, it seems there is nobody from their company colaborating in their forums This company is incredible.
As far as I can tell, you need to set the parameters for the ResultSet method as if it was a stored procedure, but I found no useful documentation about this for Java / JSP pages.
So far, my JavaBean method is:
     public ResultSet getResultSet(String minAge, maxAge) throws SQLException {
        // I don't use the parameters yet. I just want to execute this ResultSet
         try {
              return getConnection()
                   .createStatement()
                   .executeQuery("SELECT * FROM notes");
         } catch (Exception e) {
             e.printStackTrace();
             _log.error(e);
             return null;
     }An the parameters code is:
    public Fields getParameters() {
        if (_parametros == null) {
             ParameterFieldDiscreteValue val1 = new ParameterFieldDiscreteValue();
             val1.setValue("100");
             ParameterFieldDiscreteValue val2 = new ParameterFieldDiscreteValue();
             val2.setValue("200");
               Values vals1 = new Values();
               vals1.add(val1);
               Values vals2 = new Values();
               vals2.add(val2);
               ParameterField field1 = new ParameterField();
               field1.setName("minAge");
               field1.setReportName("");
               field1.setCurrentValues(vals1);
               ParameterField field2 = new ParameterField();
               field2.setName("maxAge");
               field2.setReportName("");
               field2.setCurrentValues(vals2);
               Fields fields = new Fields();
               fields.add(field1);
               fields.add(field2);
               _parameters = fields;
        return _parameters;
    }Any comment of any kind about this would be really welcome.
