Using a PyDev console in Eclipse, which initially worked fine. Python code would work inside the console. When I started writing a file within a PyDev module, I tried executing runfile() but the console that had already initialized with python returns this error:

Failed to parse server's response: Expected methodResponse element, got head127.0.0.1 - - [18/Jul/2015 13:55:14] code 400, message Bad HTTP/0.9 request type ('POST')

After which, I closed the console and restarted Eclipse. Now, when I try to even initialize the pyDev console it returns this:

Error initializing console.Unexpected error connecting to console.Failed to recive suitable Hello response from pydevconsole. Last msg received: Failed to parse server's response: Expected methodResponse element, got head

One solution is to use Liclipse, which comes with python integration, all you have to do is to configure the interpreter. Or check weather your interpreter is configured correctly. The configuration is found at Window->Preferences->Pydev->Intrepreters. Or another thing that might be wrong is that the pydev module might be for a certain type of eclipse. I personally use LiClipse which is great.
