Metro 与 Java 的 JAX-WS？

Metro vs Java's JAX-WS?

提问by Arci

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?

Java 的 JAX-WS 和 Metro 的区别是什么？它们是相同的还是两个不同的 JAX-WS 实现？

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.

根据我的研究，JAX-WS 已经是 JDK 6 的一部分。但是，JAX-WS 没有附带 JDK 的标准包，所以我寻找了一个 Java EE jar。但是，Oracle 似乎没有托管已编译的 Java EE jar，而是提供了作为 Java EE 服务器的 Glassfish。

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?

我能够在 Glassfish 上运行我的网络服务。Glassfish 使用什么 JAX-WS 实现？由于它托管在 Oracle 上，我假设它使用的是 Java 的 JAX-WS 实现，据说它是 JDK 1.6 的一部分？我的假设正确吗？此外，要运行基于 JAX-WS 的 Web 服务，我需要下载 JAX-WS jar。我找到了地铁。但是在它的页面上，我看到地铁的链接是 Glassfish 的子链接。所以我现在很困惑。Glassfish 使用 Metro 吗？还是 Glassfish 使用 Java 的 JAX-WS？

Are Metro and Java's JAX-WS the same?

Metro 和 Java 的 JAX-WS 是否相同？

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.

JAX-WS 是一个 API，而 Metro 是 JAX-WS API 的参考实现；两者都来自 Sun/Oracle，因此是标准的。您可以将它们视为一个接口 (JAX-WS) 和一个实现该接口的类 (Metro)，只是在更高的级别。Glassfish 还使用 Metro 作为 JAX-WS 的实现。

To be noted that Metro contains implementation for JAXB and other APIs.

需要注意的是，Metro 包含 JAXB 和其他 API 的实现。

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).

此外，SOAP Web 服务在某种程度上已经过时了；新趋势是使用 REST Web 服务；JAX-RS（具有从标准 Jersey 到 Restlet 或 CXF 的各种实现）。

Accourding to Metro's home page, "Metro consists of JAX-WSReference Implementation project and Web Services Interoperability Technology project."

根据Metro 的主页，“ Metro 由JAX-WS参考实现项目和 Web 服务互操作性技术项目组成。”

Web Services Interoperability Technologies (WSIT) (previously known as Project Tango) includes implementations of:

Web 服务互操作性技术 (WSIT)（以前称为 Project Tango）包括以下实现：

• SOAP over TCP
• WS-AtomicTransactions/Coordination
• WS-MetadataExchange
• WS-Policy (https://github.com/javaee/metro-policy)
• WS-ReliableMessaging
• WS-SecureConversation
• WS-Security
• WS-SecurityPolicy
• WS-Trust

• TCP 上的 SOAP
• WS-AtomicTransactions/Coordination
• WS-元数据交换
• WS-Policy ( https://github.com/javaee/metro-policy)
