JTextpane events in linux

I used the JTextPane and Document classes for my editor. When i worked in windows the event InputMethodTextChanged for JTextPane is working fine.But the same event is not triggered or working for JTextPane in Linux.What may be the reason or is there is any alternative event for the same in Linux.
