Servlet code for both 6.1 and 6.3

[#1]

I need to write servlet code which can run in AEM 6.1 as well as in 6.3. But, as we use Felix in 6.1 and SCR in 6.3 how to write a common piece of code that works for both?

you can use felix annotations in 6.3 as well. Make sure you have felix scr annotations and other dependencies included in 6.3 projects POM.
