Load html again...

Question

Hi all,
There are lots of topics in this forum about loading HTML into applet, i tried to find answer from them to solve my problem, but i can't get the expected anwser, can anybody look at my problem, thanks.
I copy the codes from JTree tutorial( http://java.sun.com/docs/books/tutorial/uiswing/components/tree.html ), and try to create a Jar file of it, but the html pages can't be loaded. The codes are:
private class BookInfo {
public String bookName;
public URL bookURL;
public String prefix = "file:"
+ System.getProperty("user.dir")
+ System.getProperty("file.separator");
public BookInfo(String book, String filename) {
bookName = book;
try {
bookURL = new URL(prefix + filename);
} catch (java.net.MalformedURLException exc) {
System.err.println("Attempted to create a BookInfo "
+ "with a bad URL: " + bookURL);
bookURL = null;
private void createNodes(DefaultMutableTreeNode top) {
DefaultMutableTreeNode category = null;
DefaultMutableTreeNode book = null;
book = new DefaultMutableTreeNode(new BookInfo
("Print",
"hf/PrintHelpfile.htm")); //******file can't be loaded
top.add(book);
//Tutorial Continued
I know getClass().getResource("hf/PrintHelpfile.htm") can solve the problem, but i tried several ways to put it into the createNodes method, seems still can't...
Anybody can give me some suggestions, it already take me the whole day...
thanks in advance
