Hi everyone.
I am new to Drools and Spring MVC. I tried out the example from
http://blog.athico.com/2011/01/rules-based-validation-using-drools.html
http://blog.athico.com/2011/01/rules-based-validation-using-drools.html but
still I am getting an error. I have beeng looking over the net for hours
now. and have tried everything i can/know to make it work. I also have tried
multiple tutorials, blogs etc. But i still cant seem to get away from that
error.
I would greatly appreciate any help. Thanks in advance.
