有什么关系呢!

出错的信息就是在这个代码:
 try
            {
              Class jfclass=Class.forName(framename);
              Constructor con=jfclass.getConstructor(null);
              jf=(JInternalFrame)con.newInstance(null);
              ifs.put(framename,jf);
          }
          catch(Exception eeee)
          {
              System.out.print("fail2");
          }
