War deployment error related to classloading

Question

when i am deploying my war file and run it it will give error like

org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader

Answer 1

Crosscheck whether you have deployed all of your required jar files (Ex: springs.jar) in your project /WEB-INF/lib/ folder

Answer 2

The error message clearly states:

java.lang.ClassNotFoundException:
  org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader

Have you verified that the class exists within the webapp classpath?
