The URL.getFile() for "http://www.sun.com/index.html" returns "/index.html" in JDK 1.2.

The spec for java.net.URL says:
 * <blockquote><pre>
 * http://www.ncsa.uiuc.edu/demoweb/url-primer.html
 * </pre></blockquote>
 * <p>
 * In general, a URL can be broken into several parts. The previous
 * example of a URL indicates that the protocol to use is
 * <code>http</code> (HyperText Transport Protocol) and that the
 * information resides on a host machine named
 * <code>www.ncsa.uiuc.edu&lt;/code>. The information on that host
 * machine is named <code>demoweb/url-primer.html</code>. The exact

This means the file name for the URL should be "demoweb/url-primer.html", not
"/demoweb/url-primer.html" as getFile() returns.

The RFC 1738 also says the initial slash is not a part of path name (see item 3.1):

        //<user>:<password>@<host>:<port>/<url-path>

    [skip]
 
    url-path
        The rest of the locator consists of data specific to the
        scheme, and is known as the "url-path". It supplies the
        details of how the specified resource can be accessed. Note
        that the "/" between the host (or port) and the url-path is
        NOT part of the url-path.

(note the last sentence)
