Today someone told me I should give Grails a try. So we can still use our old java code for some things, but develop much faster. This isn't really a debate on what programming language is better, although if you have tips I'm all ears, but really my question is: Is Grails just an overhyped fashionable thing to use, or is it here to st...

In such cases the split method fires an exception since the regular expression is not well formed. What I am looking for is a way to ...
