Well your components are already in fixed position.
to get scroll bars on JScrollPane you just need to setup setHorizontalScrollBarPolicy and setVerticalScrollBarPolicy something as following

 Help with Code Tags 
 Java Syntax (Toggle Plain Text) 
jsp=new JScrollPane(jta1, ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED, ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS);
jsp=new JScrollPane(jta1, ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED, ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS);

Also you may want to set your JFrame as setResizable(false)
