Last thing to mention about this artifact is that starting from version 2.0 it uses JAX-WS for exposing endpoint and providing WSDL document.
if you are trying to create the separate project that uses SOAP workflow framework, then just include the dependencies in the main pom.xml file and configure the build section to create the correct WAR file.
In order to test if your set up is correct, build the project using Maven and try to deploy the built WAR file on Tomcat. If the deployment was successful, then go to the following address using your browser: http://<host>:<port>/your-application/InvokerService. You should see the minimal description of your endpoint. Note that this applies to the framework versions starting from 2.0 (JAX-WS based web services). If you want to get the WSDL document, then try to access the following URL: http://<host>:<port>/your-application/InvokerService?wsdl. You should be able to see the valid WSDL document. If the application was deployed without errors, but you are unable to access WSDL or endpoint description page, then please refer to log files, there might be some issues regarding parameter tree configuration.
