Java EE (Java Enterprise Edition) General Discussion

Hello Techies,

Java Web Services has been a nightmare for me. I would like to take your help in understanding it better. I have read many articles on it. But I did not ,yet, get a complete picture on it. They say there are JAX RPC , JAX WS , Axis and so many varities of Web Services. Its so confusing. Will you be kind enough to give a simple overview Java Web Services ? and Where do i start , If i have to learn it ? Any good source of information to learn them?

Sincere thanks.
