The version of Metro bundled with JavaSE?
Java SE 6 and later come bundled with Metro. Surprisingly, a Java ver x -> Metro ver y list is nowhere to be found.
How can I find out what version of Metro is bundled with my JVM? Either by inspecting the VM at runtime or by checking a file from the installed JVM.
JDK 6 comes bundled with JAX-WS RI. GlassFish Metro is a web services stack that includes JAX-WS RI among other components like JAXB RI or StAX, but it's a separate project. So you would have to download the Metro jars if you want to use it.
JDK 6 started including JAX-WS RI 2.0 and since update 4 it includes JAX-WS RI 2.1.
You can find the JAX-WS RI version your JDK is using with the wsimport command: wsimport -version.
Using wsimport -version as per David Lizárraga's answer, for various JavaSE 1.7.0 builds I triedon Windows and Linux, I get
JAX-WS RI 2.2.4-b01
This, and David's answer, yield the following table.
JavaSE JAX-WS RI --------+---------- 6 2.1 7 2.2.4
