Hooooy.  I tried reading your Java code..  What can I say?  There's a
reason why I like Python...  :-)

I couldn't see anything obviously broken in your server, but there's
definitely nothing wrong with your python code, except that you call
flush() on the socket (fixed in your posted code but not in the linked
code.)

Here are the results of testing, with netcat substituted for your java
server:

# on the server side:
sforman at garbage:~ $ netcat -p 54321 -l
hellohi there
how are you
I'm fine thanks

sforman at garbage:~ $



# on the client side:
sforman at garbage:~ $ python delme.py
'hi there\n'
'how are you\n'
"I'm fine thanks\n"
sforman at garbage:~ $


So I'm guessing it's something wrong in your java server.

HTH,
