Updating Method in Web-Based application - Java Servlets -

-

I am writing a servlet based back-end for a mobile phone app and I'm new to web programming in general Am

Anyway my problem is that I have a data model that connects users to a normal feed and when that feed is updated by any one user, I want to The rest of the users connected to the feed want to get the updated model

At the moment, when I send the servlet, I can send only one response, when a request is received, which is not what I am looking for, because users are ping the servlet Needing to do a few seconds that does not seem very practical, instead I want to tell the server users their answers when they change the model.

I'm sure there is a clean and well documented solution for this, I can not name it. From what I collect, I need to explicitly generate HttpResponses (I was thinking that HTTP session objects have a way of doing this, but this does not seem to happen).

There are some updates in the service update 3.0 specification. Maybe you want to check

    Obfuscating Python code? -

    -
    I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
