Answer 1

An error
1> exception not caught
public void actionPerformed(ActionEvent e)
try{
<your code>
catch(Exception ex)
ex.printStackTrace();
Explaination: your methods like search() and etc are throwing excpetion but it is not caught so you will have to catch it. The example up here is catching for all but you should tune it a bit to specific exceptions
A suggestion
1> your removeall() method is not very nice. Why don't u use card layout and hide the panel instead of removing and adding all again
