java - SOAP/HTTP + WSDL as a contract. What about JAX-WS? -

-

i'm newbie webservice, , i've read this chapter (and other articles) idea soap. sad, couldn't find next chapter wsdl in java.net.

anyway, let's suppose need implement soap 1.1/http 1.1.

the used "contract" exchange information wsdl.

so, in order create webservices provider :

  1. what role of jax-ws?
  2. would needed or alternative wsdl?
  3. if needed, shall combine ( soap/http + wsdl)?
  4. what role of jax-ws in combination?
  5. could replaced jax-rpc (or else)?
  6. is jax-ws cross-platform or specific java?
  7. if moving platform, such c or c++ or python, able use jax-ws if needed combined?
  8. talking c#,.net... jax-ws similar wcf?

thank in advance :)

soap , http message protocols. jax-ws implementation in java generating these messages. handles low level details of converting java objects soap messages, generating java classes based on wsdl , xsds. jax-ws used creating soap based rest based messages. underlying technology handles messages on both client , server side. jax-ws implementation based on wsdl , soap standards. java specific.

i not aware of wcf is.
