Metro与Java的JAX-WS？

问题描述

Java的JAX-WS和Metro的区别是什么？根据我的研究，JAX-WS已经是JDK 6的一部分了。然而，JAX-WS的实现是两个不同的JAX-WS实现吗？不包含JDK的标准包，所以我查找了Java EE jar。但是，Oracle似乎并未托管已编译的Java EE jar，而是提供了Glassfish，它是一个Java EE服务器。

我能够在Glassfish上运行我的Web服务。 Glassfish使用哪些JAX-WS实现？由于它托管在Oracle上，我假设它正在使用JAX-WS的Java实现，这应该是JDK 1.6的一部分？我的假设是否正确？另外，要运行基于JAX-WS的Web服务，我需要下载JAX-WS jar。我找到了。但在页面上，我看到地铁的链接是Glassfish的一个子链接。所以我现在感到困惑。 Glassfish使用Metro吗？或者是Glassfish使用Java的JAX-WS？

Metro和Java的JAX-WS是否一样？

JAX-WS是一个API，而Metro是JAX-WS API的参考实现;都来自Sun / Oracle，因此是标准的。您可以将它们视为接口（JAX-WS）和实现接口（Metro）的类，仅在更高级别上。 Glassfish也使用Metro作为JAX-WS的实现。

需要指出的是Metro包含JAXB和其他API的实现。

另外，SOAP Web服务在某种程度上已经过时;新的趋势是使用REST Web服务; JAX-RS（从标准Jersey到Restlet或CXF的各种实现）。
What is/are the difference/s of Java's JAX-WS and Metro? Are they the same of are they two different JAX-WS implementations?
According to my research, JAX-WS is already a part of JDK 6. However, JAX-WS does not come with the standard bundle of JDK so I looked for a Java EE jar. However, it seems that Oracle does not host a compiled Java EE jar but instead provides Glassfish which is a Java EE server.
I was able to run my web service on Glassfish. What JAX-WS implementation does Glassfish use? Since it's hosted on Oracle, I'm assuming that it is using Java's implementation of JAX-WS which is supposedly a part of JDK 1.6? Am I correct with my assumption? Also, to run a JAX-WS based web service, I need to download JAX-WS jars. I found Metro. But on it's page, I see the link of metro to be a sublink of Glassfish. So I'm now confused. Is Glassfish using Metro? Or is Glassfish using Java's JAX-WS?
Are Metro and Java's JAX-WS the same?
解决方案
JAX-WS is an API while Metro is the reference implementation for the JAX-WS API; both are from Sun/Oracle, thus are standard. You can see them as an interface (JAX-WS) and a class implementing the interface (Metro), only at a higher level. Glassfish also uses Metro as implementation for JAX-WS.
To be noted that Metro contains implementation for JAXB and other APIs.
Also, SOAP Web Services are somehow obsolete; the new trend is to use REST Web Services; JAX-RS (with various implementations from the standard Jersey to Restlet or CXF).
