I want to ask you a question about JTable with a xml file. I have written a program which can be used to load a xml file into a JTbale Swing GUI to show some informaiton about the xml file. Now I want to add a function. up till to now I can load the xml file and show the information in the JTable. It works well, no problem. But If I want to load a new xml file to dispaly the new information, I must run the programe again. It means the program can not remove the old content, and refresh to show the new infromation about the new xml file. Can you give a demo to know how to slove this problem. Thank!
