Java SE (Java Platform, Standard Edition)

hi,
I have a JEditorPane inside a JScrollPane, and the JScrollPane is inside a JFrame. I made the JFrame resizable, but the JScrollPane does not resize, i read through this link http://forum.java.sun.com/thread.jspa?threadID=528867&messageID=2543208 , and i would like to ask the following:

1) can i resize the JScrollPane if i use

container.setLayout(null);

2) How do i make a JScrollPane resize in 1 direction only, like only horizontally and vertically, when the JFrame resizes?

Thanks in advance

Regards,
yiming
