附一个用于从数据库和网络中取出中文乱码的处理函数,入参是有问题的字符串,出参 
是问题已经解决了的字符串。 
        String parseChinese(String in) 
        { 
                String s = null; 
                byte temp []; 
                if (in == null) 
                { 
                        System.out.println("Warn:Chinese null founded!"); 
                                return new String(""); 
                } 
                try 
                { 
                        temp=in.getBytes("iso-8859-1"); 
                        temp=in.getBytes("iso-8859-1"); 
                        s = new String(temp); 
                } 
                { 
                        System.out.println("Warn:Chinese null founded!"); 
                                return new String(""); 
                } 
                try

                catch(UnsupportedEncodingException e) 
                { 
                        System.out.println (e.toString()); 
                }
