as a beginner, things like scaffolds and other generated code pretty much completely eliminate these typo driven mistakes, they also make great starting points for understanding the framework. so that mitigates the problems mentioned for beginners, and by the time you are not a beginner hopefully those error messages make more sense. Personally, i found most of those error messages pretty good. im currently using spring/hibernate as well as RoR very heavily, and trust me i pull my hair out way more on the spring/hibernate side than the RoR side, come to think of it, i pull my hair out exclusively on the java side =)
