java - Refreshing the Jtable is scrolling the table -

when refresh jtable data using custom refresh button, jtable scroll random position. code used is:

jscrollpane jspane = new jscrollpane(); jtable table = new jtable(); jspane.setviewportview(table); getcontentpane().add(jspane, java.awt.borderlayout.center); 

i want jtable maintain viewport after refresh. how can achieve this?

as kleopatra said, wierd. still can force:

int scrollposition = scroll.getverticalscrollbar().getvalue(); try { ...do update table... } {     scroll.getverticalscrollbar().setvalue(scrollposition);     } }
