Apache axis, is one of the best way to deploy Web Services without needing to buy those expensive Application Servers out there. Axis is deployed as a simple web application, with web services deployed as either simple .jws files or more complex compiled classes. Web Services can either be coded as simple java classes and later renamed to .jws rather than the usual .java, when invoked via axis using a url like http://localhost:8080/axis/services/MyService.jws, Axis compiles the code and exposes it as a SOAP Web Service. The other way of deploying a web service is by compiling the code and writing something called as the "Web Service Deployment Descriptor (WSDD)" WSDD files describe a Web Service,ex: the actual class and the methods that have been exposed in the Web Service, the scope of the Web Service etc. A sample axis Web Application which contains both a service (Calc) and a Client for the Web Service (Calc.jsp) can be found here.
