Alessio Soldano is a principal software engineer at JBoss/Red Hat who has been a committer to the JBoss WS project since 2007. He leads the JBoss Web Services team. JBoss WS provides integration of the Apache CXF web services framework with the JBoss Application Server. This integration allows CXF's features and compliance with web services specifications to be used within the JBoss AS container. Alessio demonstrated how to deploy basic web service endpoints and use WS-Security with the JBoss AS 7.1 container.

3. Agenda
● What is JBoss WS ?
● Apache CXF integration
● Features
● JBoss AS 7.1
● Key features
● WS components
● Demo

4. What is JBossWS?
● “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

5. Reasons for integrating
● really good open source implementations
already available - NIH syndrome
● focus on added value
● ... a lot of Web Services specifications!

7. Who benefits from this move
● The JBoss community:
– greater joint community support
– core devs can work on added value and
application server specific integration
● The integrated ws project and its community:
– additional tests
– bugs detection and fix
– ...

8. Why Apache CXF?
● tech analysis: features, quality of code, performances,
extensibility ...
● community size / activity
● opennes to participation / involvement
– commit rights
– support paths
– need for a deal?
● driving forces behind the project?
● future potential
Apache CXF perfectly fitted, others didn't...

9. A contribution balance
● JBoss -> Apache CXF community
– Java EE TCK6 testing
– Additional testing scenarios
– Multiple bug fixes
– Endpoint.publish() API additions in JAXWS 2.2
● Apache CXF community -> JBoss
– Quick time-to-market with JAXWS 2.2
– Many WS-* features, especially in the WS-Security
area
– Multiple bug fixes
– ...

10. Features
● Inherited from Apache CXF
– JAXWS 2.2
– WS-* (RM, Security, Policy, Addressing, ...)
● JBossWS Integration
– AS integration (authentication, authorization, ...)
– Additional API (e.g. @EndpointConfig)
– Tooling (Maven, Ant, ...)
– JSR109 1.3
– JAXBIntroductions
– Common JAX-WSA JSR-261 API
– Management (console, record system, ...)

11. Do I really need your integration
layer?
● Home-brew solutions for running CXF on JBoss
AS 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 JBossWS features
– ...

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

13. How it works - deployment
● POJO endpoint
@WebService(...) <web-app ...> [optional web.xml]
<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!";
}
}

14. JBoss Application Server 7.1
● JavaEE 6 Full Profile compliant
● Fast and lighweight
● Domain management (DMR)
● Multiple management interfaces (CLI, API,
console)
● Modular classloading
● Standalone and Domain operational modes
● Arquillian support

15. JBossWS in AS 7
● webservices subsystem part of AS7 DMR
– wsdl soap:address rewrite
– pre-defined endpoint configs
● Modules
– org.jboss.ws.*
– org.jboss.as.webservices.*
– org.apache.cxf
– misc dependencies (Santuario, WSS4J, WSDL4J, etc.)
● Command line tools
– wsconsume.sh/bat, wsprovide.sh/bat

16. So, why JBossAS 7 for WS?
● Lightweight yet full JavaEE6 compliant container
● Fast start-up / easy development & testing
● Apache CXF integration
– Wide range of WS specs coverage
– Performances
● Peace of mind coming from
– “joint” JBoss / Apache CXF community
– Red Hat support if moving to Enterprise Platform

17. 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>

18. Demo -> OpenShift
● WS-Security interoperability endpoints
