When you are dealing with following exception, you should check if they're no errors in your classpath (for example two different JARs for AOPAlliance project):
[2012/12/12 11:22:05.927] org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'org.springframework.transaction.interceptor.TransactionInterceptor#0' must be of type [org.aopalliance.aop.Advice], but was actually of type [org.springframework.transaction.interceptor.TransactionInterceptor]
