Answer 1

Hi its very clear from your exception that , you dont have all spring jars in your classpath.

if you are using maven add all dependencies in pom.xml.

otherwise download the jars from spring source and add them into project classpath.

once you add and run , it will work properly.

i don't see any aplication related errors over there. its only jar problem.

either missing jars or version mismatch. check it properly.
