Post a small demo code that is generally compilable, runnable and could reproduce your problem. See: http://homepage1.nifty.com/algafield/sscce.html and http://www.yoda.arachsys.com/java/newsgroups.html

Swing related questions should be posted in the Swing forum.

If you are simply attempting to position the scrollbar at the bottom after appending text to the text pane then use the following instead:

textPane.insertString(....);

textPane.setCaretPostion( textPane.getDocument().getLength() );
