  1. Hello friends..I am new to this forum .
    I am developing small application using NetBeans 7.0 which has a JList on the form from the palette . I am filling the JList using the vector which contains records from database. But I can not clear the contents of the JList. Please help me friends. Here is my code

     
    private void dateChooserSelectedDatePropertyChange(java.beans.PropertyChangeEvent evt) {                                                       
     
            DefaultListModel model = new DefaultListModel();
            listSerialNo = new JList(model);
     
            UpdatePurchase updatePurchase = new UpdatePurchase();
            Vector<String> serialNo = new Vector<String>();
            serialNo = updatePurchase.getSerialNoForSelectedDate(date);
            if(serialNo.size()>0){
                listSerialNo.setListData(serialNo);
            }
            else{
                model.clear();
                resetFields();
            }
        }

    If I use above code then neither Jlist contains any record nor it clears the contents of JList . If I remove
    DefaultListModel model = new DefaultListModel();
    listSerialNo = new JList(model);
    // if & else code from above code snippet
    model.clear();
    then atleast JList contains some records for specific date if available.

    My aim is if there are records available for specific date then that record should be displayed in JList otherwise JList should be empty. Please guide me.
    Thanks .
