Can You Help Me ABout getSelectedRow in JTable

Question

Can you help me on how to solve my problem about the getSelectedRow .....
I have one JComboBox and a SearchButton
... Once I selected an Item in a JComboBox, I will press the SearchButton
and then it will look up to the database and display it in the JTable..........
i used the getSelectedRow to print the value that I selected in the table...
like this...
public void mouseClicked(MouseEvent e) {
// Ilabas yung form
if(e.getClickCount() == 1 ) {
System.out.println(table1.getSelectedRow());
In the first press in the SearchButton and then clicking the row
, It will print the selected row...... but when i press again the SearchButton then clicking a row again........
there is a problem occured....... selectedRow is always -1, can you help me to solve this.....
