Thanks for the help. I'm not sure why, but I still have servlet-api:2.5 in
my dependencies, as well as javax.servlet-api:3.1.0. I read somewhere that
javax.servlet-api replaced servlet-api... I removed it manually but it's
being brough in from somewhere and I can't work out where. For the first
time in a year I wish I was back in eclipse instead of IntelliJ IDEA :( Any
chance you can look at my pom.xml files and help me work it out?
