Java GUI aplication, load data to Jtable from a list i have found the following link but i haven't found an answer: http://docs.oracle.com/javase/tutorial/uiswing/components/table.html

The tutorial you linked to has an example: http://docs.oracle.com/javase/tutorial/uiswing/components/table.html#data. You should be able to adapt it to a List<Employee> easily:
public int getRowCount() {
return list.size();
}
public int getColumnCount() {
return 5;
}
public Object getValueAt(int row, int col) {
Employee employee = list.get(row);
if (col == 0) {
return e.getName();
}
else if (col == 1) {
return e.getGrade();
}
...
}
Using vector should help you. Load an array to a Java table.
Vector model = new Vector();
Vector row = new Vector();
row.add("abce");
row.add("def");
row.add("ghi");
model.add(row);
row = new Vector();
row.add("sds");
row.add("sdfds");
row.add("24");
model.add(row);
JTable table = new JTable(model);
All the methods of Vector is synchronized. But, the methods of ArrayList is not synchronized.
