The org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader is now located in the spring-instrument-tomcat.jar, which can be downloaded from Maven Central or Spring Source.

If you want to configure load time weaving on Tomcat, you need to place org.springframework.instrument.tomcat.jar into lib folder of Tomcat installation directory, as described in the documentation.

Otherwise, if you don't need it and accidentially used wrong context.xml, you need to remove <Loader> element from it.

Whenever you see an exception with something of this effect (i.e. a ClassNotFoundException):

java.lang.ClassNotFoundException: xx.xxx.class.ClassName

You must know that the (from JavaDoc of ClassNotFoundException):

no definition for the class with the specified name could be found.

In this case, com.vaannila.service.UserServiceImpl cannot be found (from error log: java.lang.ClassNotFoundException: com.vaannila.service.UserServiceImpl).

Make sure you have the jar file included in your project (containing com.vaanila.service.UserServiceImpl).
