I received run-time error for string
ApplicationContext context = new ClassPathXmlApplicationContext(\"Beans.xml\"); java.lang.NoClassDefFoundError: org/sp
That's a Spring 3.1 (still a milestone release) class. If you're intending to use Spring 3.0, you must have mixed in some 3.1 stuff accidentally.
I think that need use version 3.1.0 - in package org.springframework.core-3.1.0.M2.jar this class presents.
