Do JAX WS implementation classes come as part of the Java 5/6 package or only as part of an application server libraries?

Question

Do JAX WS implementation classes come as part of the Java5 package, as part of the Java6 package or only as part of an application server libraries like WAS?

I read that it comes as part of Java EE? What does that mean? Java 5?

Answer 1

JAX-WS is an API which is part of both JavaEE 5 and JavaEE 6 APIs. The implementation of JAX-WS is not part of the JavaEE API. There are multiple implementations of the JAX-WS; noticeable ones are:

• Metro - the reference implementation, and part of the Glassfish application server (it is open-source so you can easily find sources)
• CXF - part of an Apache open-source project (easily found sources)
