Java SE 6 Update 4 is now released. Download it here.

If you are a Metro user (either JAX-WS or WSIT) then this is a milestone release for you because it includes JAX-WS 2.1 API in thert.jar. This means that, as a user, you no longer you need to copy JAX-WS or JAXB API jars inJAVA_HOME/jre/lib/endorsed as described here, here and here. Hurrah!

After you have downloaded and installed JDK 1.6 U4,java -version shows:

java version "1.6.0_04"
Java(TM) SE Runtime Environment (build 1.6.0_04-b12)
Java HotSpot(TM) Client VM (build 10.0-b19, mixed mode, sharing)

wsgen -version shows:

JAX-WS RI 2.1.1 in JDK 6

wsimport -version shows:

JAX-WS RI 2.1.1 in JDK 6

Additionally, you can also verify by greping for class inJAVA_HOME/jre/lib/rt.jar. This is a new class introduced in JAX-WS 2.1.

Now after you've installed Java SE U4, you can download Metro 1.1, set JAVA_HOME to point to this new Java SE installation and you can easily import a WSDL as:

wsimport -d temp http://localhost:8080/MetroWithJavaSE6/HelloService?WSDL
parsing WSDL...

generating code...

compiling code...

If you try to import the same WSDL with an earlier release of Java SE 6, then you'll see the error message:

You are running on JDK6 which comes with JAX-WS 2.0 API, but this tool requires JAX-WS 2.1 API. Use the endorsed standards override mechanism (, or use -Xendorsed option.

We hope this will make your life simpler :)

Metro 1.0.1 is anyway baked in GlassFish v2 UR1. You can override it with Metro 1.1 as described in TOTD #21.
