I will defer the WS talk to as I wonder if t is achievable via Spring Integration, but you can easily create an add-on that installs the spring-ws dependency and configures an application context.
For an example look at the Spring Roo Jms add-on source code. I would approach it in the same way as that add-on.
If this is a one-off configuration, and not something you want to write an add-on for, just mount spring-WS dependencies in your project Pom and configure the
servlet in web.xml and the services appropriately.
REST support is built in to Spring Roo projects as it uses Spring MVC's RESTful controller support. This is not the case with
SOAP services though.
