MemcachedClient memc = new

String key = "00a8d7a51e0b0b1fda0b36eff8f9dc22";
Object memcHash = memc.get(key);

getLogger().info("got from memcache: ------>" + memcHash );

in logs always null:
got from memcache: ------>null

in 'memcached -vv' logs I can see that this key exists and was sent:

===
<36 new auto-negotiating client connection

What am I doing wrong?

When I try 'set' in my coge and then get  - I receive the data. When I try put 
data from php and get this key from telnet - I receive the data (this is json 
string in UTF-8 encoding),  but when i try to get from java - i receive null.

After I replace the data (mc.set("mykey",3600,"111")), then it reads 
successfully.

Hi,

yes - this is somewhat expected. You are running into the problem that 
different clients use different flags for this. I dont know which drivers you 
use on the PHP side, but you need to make sure to use the same flags for both 
data - or just use no flags at all on both sides.

I recommend you to watch this hangout from some couchbase devs that cover 
interoperability - and this directly translates to memcache as well!
