The web client typically use a servlet filter, ServiceContextServletFilter. We provide implementations for jboss (JBossServiceContextFactory) and other servlet containers such as tomcat and jetty (ServletContainerServiceContextFactory). The servlet filter puts the ServiceContext object in ServiceContextStore, as a thread local variable. The action/controller class in the client gets it from ServiceContextStore and pass it to the service as an ordinary method parameter. The reason for this is that the service could be remote or not execute in same thread.
ServiceContextStoreAdvice is placed in front of the service method and picks the parameter and puts it in ServiceContextStore, for later usage of for example AuditInterceptor. The ServiceContext is by default passed as first parameter in business tier methods. This can be turned off if you don't need auditing or use another mechanism to create the ServiceContext object. I'm currently investigating the possibility to create ServiceContext instance with an interceptor in front of the service methods, and populate it from jboss jaas context. That would mean that the ctx parameter is not necessary. That is probably a jboss/ejb specific solution. One thing strikes me. For web application without ejb, it is enough with the servlet filter. No parameter and no ServiceContextStoreInterceptor is needed. Yes, we could write some more docu about this. There is some in javadoc of the classes mentioned above.
