Height of a component will usually decided by the LayoutManager - you can set a preferredSize, but this will be used only as an hint by the layout managers...
Why do you need to set the height? have you added the text pane to a JScrollPane - this will allow the user to enter as much text and scrollbar will appear automatically if the text exceeds the visible height.
