Choosing the Right Programming Language for Fast Server Side Development
I'm in the process of designing a client/server based mobile application and have come to the point where I need to decide the language to use for the server side development. In the first stage of this application development I need to sustain a couple of thousands of simultaneous users who can chat with each other and manage their profiles. Most of the data transferred will be textual so no heavy stuff. What I do need is to get it up and running as soon as possible.

Most of my experience is in C/C++, but as I get it they're not very useful for this type of programming. I've been contemplating between using Java and Python, both are languages I have touched in the past but am not very experienced with. What are the pros and cons of these two languages and which one you think might fit better for this task? I'm open to other languages as well.
