google app engine access version number

Question

I want to access the version number specified in my XML config file from my java code. How could I do this?

The goal is to make sure that users will have access to the latest version of my JavaScript by appending it to it file.js?x=version-number

Answer 1

I am assuming that the version # you are refering to is your application version number and not the current App Engine Version.

If that is the case, you could look at the following approaches:

• Ship a version.txt file with your web application that is updated with every new version that you push to App Engine.
• Have a Version.java, where you keep the current version
• There could be an initialization Servlet that could have an initParam that refers to the current version #.

Each of these have their +/- points - but you could pick an approach.
