额，意思很明显，路径名称不可用。
也就是说，你要保存的这个路径有问题。我们写的有电不一样，不过你看看我咋写的：
<form
action="<%=request.getContextPath()%>/save.day05cjsp?username=<%=u.getUsername()%>"
method="post" enctype="multipart/form-data">
照片路径:
<input type="file" name="file1" />
<input type="submit" value="上传" />
</form>

private static void save(HttpServletRequest request,
HttpServletResponse response, String path) throws ServletException {

DiskFileItemFactory df = new DiskFileItemFactory();
ServletFileUpload su = new ServletFileUpload(df);
su.setSizeMax(500 * 1024);
String username = request.getParameter("username");

try {
List list = su.parseRequest(request);
for (int i = 0; i < list.size(); i++) {

FileItem fi = (FileItem) list.get(i);
if (!fi.isFormField()) {

String pic = fi.getName();
if (pic.length() > 90) {
// 数据库中存放文件名的列最大长度为90，为了向数据库存入文件名时不出现异常，所以在此过滤
request.getRequestDispatcher("/load.day05ujsp")
.forward(request, response);
return;
}
pid.save(new Pic(username, pic));
fi.write(new File(path + "/day05/" + username, pic));
}
}
request.getRequestDispatcher("/load.day05ujsp").forward(request,
response);
} catch (Exception e) {
e.printStackTrace();
}

}

"The requested resource (/biyesheji/servlet/servletUpload) is not available"
你的servletUpload的设置不对。
