Are JAXWS and Metro documentation same?

[Vicky Roy]

Hi All,
Currently I am preparing for Web Service certifiction and reading the below JAXWS / Metro documentation. Now, I have a query. Since Metro is RI (reference implementation) of JAX-WS so are these both documentation same? Should we really look into both of them or only one will serve the purpose.

https://jax-ws.java.net/nonav/2.2.6/docs/index.html

https://metro.java.net/2.3/guide/index.html

Thanks.

Looking at the table of contents, they aren't the same. They do appear similar though. I think once you read one, you'll be able to skim the other for the highlights.

Metro is more than just the JAX-WS RI, so its docs would be different.

[Vicky Roy]

Sorry for my poor understand but still I didn't get. According to Jeanne, other one can be skimmed after first means one is supposed to read both. And as per Dittmer, Metro is more than JAX-WS so for web services, do we need both?

[Ulf Dittmer]

That depends on which topics you're interested in. For example, WS-Security is implemented by Metro, but is not part of the JAX-WS. So if you want to learn about that, you need the Metro documentation.

So it means Metro supercedes Jax-ws, right? It means by following Metro, you will cover everything including JAX-WS because Metro is RE of jax-ws.
So if one is doing certification or one is fresher or one is supposed to follow a diff jax-ws implementation like axis, following Metro is fine.

Correct me if I am wrong.

Thanks.

No. Metro includes the JAX-WS RI (which is one of the implementations of the JAX-WS API) - it is a superset of the JAX-WS RI.

So if one is doing certification or one is fresher or one is supposed to follow a diff jax-ws implementation like axis, following Metro is fine.

I'm not sure what you're saying here, but Axis2 is a different implementation of the JAX-WS API. Following Metro won't teach you anything about Axis2, and vice versa. (Of course, Axis2 has been stagnant for a while, so nothing much to follow there.)

Go with what Ulf said. I just looked at the table of contents.

[Vicky Roy]

Sorry for the confusion but I just wanted to say that following Metro will be more than enough no matter if one is going for certification or just WS development or any other implementation (in that case at least he will get the jax-ws expectations but implementation will be different). Hope I am clear enough now

OR is there any particular reason one should see jax-ws also?

Thanks.
