As text content grows in size, whole screen scroll including textbox. I want only content of textarea to be scrolled.

well, you can forbid scrolling for the whole form using Form.setScrollable(false). Then you just set your HTMLcomponent scrollable "true" with the same method and finally put these two components (TextArea and HTMLComponent) to a different cosntraints (e.g. TextArea in BorderLayout.NORTH and HTMLComponent in BorderLayout.CENTER)
