JSP and Servlet maintenance on Tomcat -

-

I'm developing JSP / servlet webpage on the Tomcat, I have some things (sublet Class, Web XML, JSP etc.) How can I refresh, while it is working?

I can use a boolean variable in my servlet to find out that this will be a maintenance period, requests will be ignored. (All my servlets extend my base service class, so I only have to do one thing "if" check in my base class and a gestਟਰ / siter in boolean) but this file is not enough to refresh .

Do I have to shut down my app, change things and re-deploy? When I refresh the app, I want to show the "Maintenance period, please wait ..." page for my users

How should I do this?

Only on a "maintenance" page is it possible that if you are in front of Tomcat from another web server The commonly used approach that is linked to Tomcat, while keeping WebPooling on Tomcat, just display HTTP Maintenance page rather than forwarding to Tomcat's request.

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).
