Answer 1

Check if you have defined all the beans in your version of the spring-config.xml and in case if you are Autowiring annotations, please check if your bean classes are annotated.

Answer 2

Its hard to answer based on the stack trace above,

but I see a java.lang.NoClassDefFoundError: , which is an indication that you are mising a dependency at run time. I'm not sure how your project is set up , but check you container settings for missing dependencies.
