Help! Urgent!!! tree in web page

Question

I am new in Swing. I need to implement a tree in web page. The tree should appear in the left of a frame and the corresponding content should be displayed in the right of the frame.
Could anyone give me an example? I need this help very urgently. Thank you very much in advance.
