spring webapp library jars at ear level

My question is

I tried to find out the answer but couldn't find matching to my case开发者_StackOverflow社区. Experts please tell me what are the pros and cons of this structure, issue that might occur with class loading etc. Or tell me if I am completely wrong about my question.
