Summary

@ivar_grimstadJDD 2014

Spring 4 and Java EE 7solves the same problem

@ivar_grimstadJDD 2014

Java EE 7 require less configuration and

dependencies

@ivar_grimstadJDD 2014

Spring 4 is more portable

@ivar_grimstadJDD 2014

Using Spring 4 from Java EE is easier

@ivar_grimstadJDD 2014

Mixing is possible

@ivar_grimstadJDD 2014

…but…

@ivar_grimstadJDD 2014

Favor one framework over mixing
