What resources exist to teach me how to use web services in Java?

I'd like to learn to use web services in java, but I can't figure out how to get started.

Are there any websites which could teach me these concepts, particularly those which include ex开发者_如何学Pythonample code?

Try this JAX-WS hello world example to understand the basic of how web service works in Java.

In addition, I would recommend you getting and at least scanning through JSR-224 (Java API for XML-Based Web Services), which is de facto API for building Web Services in Java. It is very technical document, but might help you understanding on how to use one or another feature of Java Web Services. As it comes to implementation, you have a choice of multiple frameworks. One of them - Apache CXF - is mentioned in other comments along with links to the tutorials.
