[FIXED] how to get a string from memcach on appengine - java

Issue

I'm using memcache on appengine. I inserted a json string:

private static CacheFactory cacheFactory = CacheManager.getInstance().getCacheFactory();;
private static Cache cache = cacheFactory.createCache(Collections.emptyMap());;
String data = "{\name\": \"jim\"}";
cache.put("1234", data);

now I'm trying to get the string from memcache and create a json object:

JSONObject dataObj =   new JSONObject(cache.get("1234")); // log  => {name: "john"}

this works for me well, and I get the expected JSON -> {name: "john"}.

Now I am getting the data before I create the json;

Object myData = cache.get("1234");
JSONObject dataObj =   new JSONObject(myData); // log => {"bytes":[123,34,110,97,109,101,34,58,34,106,111,104,110,34,125],"empty":false}

and now I am receiving the data in an byte Object -> {bytes: [12,..],empty: false}

What's going on? Isn't there an expected behavior?

EDIT I will note that when on the memcach-console the value is saved ok -> {name: "john"}

Solution

Instead of

Object myData = cache.get("1234");

try

String myData = (String) cache.get("1234");

By the way, on App Engine I am using the following code:

MemcacheService memcache = MemcacheServiceFactory.getMemcacheService();
memcache.put("1234", object);
String myData = (String) memcache.get("1234");
