java验证码 memcache_在java中实现Memcache的错误

我试图用Java写一个简单的代码来连接到一个memcache服务器。我使用spymemcached 2.8 jar，但我得到一个“服务器重新连接”错误，我无法理解。

代码是：

**client = new MemcachedClient(new BinaryConnectionFactory(),AddrUtil.getAddresses("127.0.0.1:11211"));

} catch (IOException e) {

e.printStackTrace();

System.err.println("connection problem");

}

client.set("someKey", 3600, new Integer(10));

Object myObject=temp.client.get("someKey");

System.out.println(myObject);

client.delete("someKey");**但我得到的错误是：
