Hello-service is a project mainly written in Java, it's free.
Hello World Web Service
When you checkout the project from GIT before using, run mvn package.
Maven integration still sucks for Eclipse when doing anything that deals with facets such as dynamic web projects. However, it is still better than maintaining extra code (i.e. Ant build files).
For real-life, I would recommend Maven to bootstrap the project, then use Ant to do the builds, because there are more people who know Ant than Maven (caters to the lower denominator). I would still try to use the Maven source structures if possible, at least on Eclipse it works.
This example project lumps all levels (service implementation, service interface, integration test) in one project. This is not recommended for real-life. I would break things up in the following way:
Ideally the grouping should be one per enterprise group.
The WSDL should be stored in META-INF/wsdl so we can extract the data using the maven-dependency-plugin.
Service Implementation Integration Test. This is a support project for those than need to test integration for a deployed project.
Web Service EAR. This will contain multiple web service container projects. Ideally the versioning should be based on a release schedule be it by year or half year (like Ubuntu) or monthly (if you do things that quickly).
There is no such thing as a client project. Unlike Stateless Session Beans, WSDL already provides the information to build the client and the interface for any language that supports it. Therefore, don't add any more work for yourself.
