Deployment strategies for Web Services

I need to come up with a strategy for deploying multiple versions of JAX-WS Web Services. I am currently looking at:

• 1 .war per service and 开发者_如何学JAVAper version.

This offers the maximum flexibility. Deprecation of an old version is straightforward, as well as introducing new versions.

• 1 .war per service and multiple versions.

This involves having 1 .war for all the versions in a service. Less flexibility but a change in a common resource does not mean deploying multiple .wars.

Any insights?
