JAX-RPC / JAX-WS runtime in Apache Tomcat

问题

I am using Apache Tomcat v6 server. While creating a new Web Service, I get the Web service runtime options for "Apache Axis", "Apache Axis2" and "Apache CXF2.x".

Is it possible to have the runtime as "JAX-RPC" or "Jax-WS"?

EDIT:

I am using Eclipse IDE

回答1:

JAX-RPC and JAX-WS are specifications, Axis, Axis2 and CXF are implementations.

for JAX-RPC you need Axis (1)
for JAX-WS use CXF (I believe Axis2 also supports this spec but I've never used it)

If you have a choice I strongly recommend the latter (JAX-WS) as it's the more modern spec and more importantly the toolkits are being actively developed and updated - Axis 1 has been dormant for years and relies on old versions of a number of other libraries.

You're also likely to get better performance with a more modern toolkit like CXF or Axis2, which has been designed from the beginning to use streaming XML APIs wherever possible, rather than building a tree model in memory.

I'd like to expand and upon Ian Roberts answer and give you more options.

JAX-RPC

This is an older standerd. You can still find an implementation for it JAX-RPC SI (standard implementation) : http://java.net/projects/jax-rpc/

Also, many of the JAX-WS implementations will implement the old JAX-RPC standard. JAX-WS replaced JAX-RPC and you shouldn't really need it if you are creating a new project.

JAX-WS

JAX-WS standard: http://jcp.org/en/jsr/detail?id=224

JAX-WS implementations:

JAX-WS RI (reference implementation) : http://jax-ws.java.net/

Apache CXF : http://cxf.apache.org/docs/jax-ws-configuration.html

Apache Axis2 : http://axis.apache.org/axis2/java/core/

JBOSS-WS: http://www.jboss.org/jbossws (Easy if you choose jboss over a bare tomcat, pros and cons come along with this)

Choosing the right library

If you just want to get something up and running you can just have eclipse use Axis2 or CXF. (Just google "Eclipse Axis2" or "Eclipse CXF" and you'll find plenty of tutorials and videos on getting up and running.) I personally use JAX-WS RI, but all of the above options have pros and cons.
