Question

I’m trying to write a simple code in Java to connect to a memcache server . I using the spymemcached 2.8 jar but I am getting a “server reconnecting” error which I’m unable to understand.

Code is:

    **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");**

    

But I’m getting errors which are:

Anyone having any idea or suggestion? .. please reply…

Timed out waiting for operation - failing node: /127.0.0.1:11211
this means your memcached binded on other adress or it’s not started.
