3. ● AS7 services
● AS7 subsystems
JBoss Web Services
JBoss WS
●
● Apache CXF integration
● Features
AS 7 Web Services extension
●
● Model
● Modules & classloading

4. Services
● Almost everything is a service
● Services are objects that can be started and stopped
● Services can have dependencies on other services
● Services can't start before their dependencies are
not satisfied
● Before stopping all dependent services will be
stopped
● Services can inject dependent services

5. Service examples
● Of course core services, but also
– EJBs
– JNDI bindings
– Servlets
– Deployments
– Registries
● Individually shutdown and restart with all
dependencies being maintained
– e.g. XTS endpoints

6. Subsystems
● A subsystem implements a “logical” area of the
server
– subsystem:datasources
– subsystem:messaging
– subsystem:ejb3
– subsystem:webservices
● The subsystem can provide user visible
configuration
– datasource definitions
– web connector configurations

7. Subsystems
● Custom subsystems can be implemented for
functionality outside of the application server
● The subsystem consist of an extension
– org.jboss.as.controller.Extension
● Other components
– Schema
– Parsers
– OperationHandlers
● Example: org.jboss.as.webservices extension
– Model
– Modules

8. What is JBoss WS?
● “Just” a feature-rich JAX-WS compatible ws
stack till early 2008...
– AS 4.x, AS 5.x target containers
● ... a web services framework providing
integration layers for 3rd party ws stacks on top
of multiple JBoss AS versions
– CXF, Native and Metro stack
– AS 5.x, AS 6.x target containers
● ... the interface and integration point of Apache
CXF in JBoss application server
– AS 6.x, AS 7.x target containers

9. Apache CXF integration
● Standards & specifications
● NIH syndrome & wider community
● Added value
● Home-brew solutions for running CXF on JBossAS
might work for specific usecases, but you...
– need to embed the stack in your apps
– will suffer from classloading issues
– can just use pojo endpoints
– have no webserviceref injection in ejb3
– loose additional Web Service Framework
features ;-)
– ...

10. How it works - runtime
Request flow
WS-* ...
Endpoint servlet
RequestHandler
Invoker
JBoss
Apache CXF AS
JAX-WS
... handlers
Response flow

11. How it works - deployment
● POJO endpoint
@WebService(...) <web-app ...>
<servlet>
public class MyEndpoint { <servlet-name>TestService</servlet-name>
public String sayHello() { <servlet-class>org.jboss.test.ws.jaxws.samples.MyEndpoint</servlet-class>
return "Hello World!"; </servlet>
} <servlet-mapping>
} <servlet-name>TestService</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
</web-app>
● EJB3 endpoint ● Create metadata to
deploy jboss-web app
@WebService(...) ● Create CXF bus
@Stateless ● Customize CXF bus
public class MyEndpoint { ● Start web app for
public String sayHello() { published endpoints
return "Hello World!";
}
}

12. Demo
● Basic WS endpoint deployment
– AS7 console
● WS-Security UT Profile JAAS integration
– Policy driven approach
– AS7 / CXF security integration
<subsystem xmlns="urn:jboss:domain:security:1.1">
<security-domains>
<!-- ... other security domains ... -->
<security-domain name="JBossWS">
<authentication>
<login-module code="UsersRoles" flag="required">
<module-option name="usersProperties" value="jbossws-users.properties"/>
<module-option name="unauthenticatedIdentity" value="anonymous"/>
<module-option name="rolesProperties" value="jbossws-roles.properties"/>
</login-module>
</authentication>
</security-domain>
</security-domains>
</subsystem>
