How to use TableSorter class with DefaultTableModel

Question

Hi Friends
Please tell me how to use TableSorter Class which is in the Java. Tutorials with DefaultTableModel.
i saw in a thread there it was given that we have to pass the DefaultTableModel to the TableSorter Class.
I tried to use like that. But i am getting Error Like Exception occurred during event dispatching:
I am posting the part of Code where i use the DefaultTableModel
     private void displayavailablity(String selectedAuthor)
               try
                    Vector columnNames = new Vector();
                    Vector data1 = new Vector();
                    String bname,bauthor,bcategory,bref1,bavail,bid;
                    int bref,mid,num;
                    rs = st.executeQuery("SELECT BId,BName,BAuthorName,BAuthorandPublisher,BCat FROM Books where BAuthorandPublisher='" +selectedAuthor+"'");     
                    ResultSetMetaData md= rs.getMetaData();
                    int columns =md.getColumnCount();
                    String booktblheading[]={"NUMBER","BOOK NAME","AUTHOR","CODE","CATEGORY"};
                    for(int i=1; i<= booktblheading.length;i++)
                         columnNames.addElement(booktblheading[i-1]);
                    while(rs.next())
                         Vector row = new Vector(columns);
                         for(int i=1;i<=columns;i++)
                              row.addElement(rs.getObject(i));
                         data1.addElement(row);
                         //System.out.println("data is:"+data);
                    ((DefaultTableModel)table.getModel()).setDataVector(data1,columnNames);
                    TableSorter sorter = new TableSorter((DefaultTableModel)table.getModel());
                    rs.close();
               catch(SQLException ex)
                    System.out.println("ERROR IS HERE");
                    ex.printStackTrace();
     }Please help me on this issue Otherwise Please give me some Sample coding to implement this sorting. with DefaultTableModel
Thank you for your service

I don't know about any TableSorter class, but I suppose you mean javax.swing.table.TableRowSorter.
The TableRowSorter is to be attached to the JTable, not to the data model. Here's a cut'n'paste from the last time I used it:
RowSorter<TableModel> sorter = new TableRowSorter<TableModel>(tableModel);
myTable.setRowSorter(sorter);
And heres from the JDK1.6 documentation:
TableModel myModel = createMyTableModel();
JTable table = new JTable(myModel);
table.setRowSorter(new TableRowSorter(myModel));
Check out http://java.sun.com/javase/6/docs/api/javax/swing/table/TableRowSorter.html. I find it to be good documentation.
