Java™ API for XML Web Services (JAX-WS)
The Java API for XML Web Services (JAX-WS) simplifies creating and deploying web services and web services clients.
The Java Platform, Standard Edition version 7.0 includes JAX-WS 2.2.
Backward Compatibility
Two small source compatibility anomalies exist between JAX-WS versions 2.1 and 2.2. The changes in the API are as follows:
- In
the
FaultActionannotation, theclassNameelement's type changed from being a plain vanillajava.lang.Classto beingjava.lang.Class<? extends java.lang.Exception>. - In
the
WebServiceRefannotation, thevalueelement's type is now more specific. Instead of beingjava.lang.Class, the type is nowjava.lang.Class<? extends Service>.
Because of these changes, some applications that compile with Java SE release 6 might not compile with Java SE release 7. There will be a deployment error if incorrect types are used with JAX-WS 2.1 API. In Java SE release 7, these type errors are caught at compile type instead of deployment time.
