JAX-WS 和xfire，axis这种有什么区别？

JAX-WS is Java's web service implementation. Latest release supports annotations. According to Java EE 5, you can easily annotate a POJO and/or stateless EJB to expose them as web services.

JAX-WS uses JAXB for data binding, which means xml and Java classes can be mapped automatically, with xml schema defined properly. This is a very important feature that lots of web services lack.
