I think the issue was by ths following , What I Want to Do ? , (As discussed in comments...)
You have two problems:

code :

catch (ParseException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

catch (ParseException e) {
    throw new DataValidationException(
        "Error parsing date: " + textField_5.getText(), e);
}

Any of those help A JPanel inherits from java.awt.Container, which maintains an internal list of client components (your JButtons in this case). You can find this list in the source code of Container:

code :

/**
 * The components in this container.
 * @see #add
 * @see #getComponents
 */
private java.util.List<Component> component = new java.util.ArrayList<Component>();

should help you out Here is a simple way if you want to pass the First and Last Name of the logged on user to the MainWindow.
First, modify your query to get Last and First name when you verify if user exists in your database :

code :

String sql = "select FName, LName from tblCustomer where username = '" +username+"'and password = '"+password+"'" ;
rs = st.executeQuery(sql);

int count = 0;
String lastName ='';
String firstName = '';
while(rs.next())
{
  count ++;
  //get last name and first name when connected
  lastName = rs.getString("LName");
  firstName = rs.getString("FName");
}

if(count == 1)
 {
   setVisible(false);
   new MainWindow( firstName+" "+lastName);//<--pass it here to the mainWindow
 }

public class MainWindow extends JFrame {
    private String whosLoggedOn;
    MainWindow(String whosLoggedOn) {
         this.whosLoggedOn = whosLoggedOn;

         //------ other stuff--------

         //Create text based label
         JLabel lblMessage = new JLabel(this.whosLoggedOnis+ " is currently logged on.");
        //------ other stuff--------

  }
  }

  public class MainWindow extends JFrame {
    MainWindow(ResultSet tblCustomer, ResultSet tblAccount ) {


         //use them as you want here
         //for example to get last and first name :
          String lastName = tblCustomer.getString("LName");
          String firstName = tblCustomer.getString("FName");

         //Create text based label
         JLabel lblMessage = new JLabel(lastName +" "+ firstName" is currently logged on.");
        //------ other stuff--------

  }
  }
