JBoss AS7 Webservices
0 likes693 views
This document discusses JBoss Web Services and how it integrates Apache CXF into JBoss Application Server. It provides an overview of how JBoss WS works at runtime and during deployment. Key points include that JBoss WS allows CXF to be used on JBoss AS, addresses classloading issues, and provides features like web service reference injection. It also demonstrates configuring security using the WS-Security UT Profile and JAAS login modules.

- 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>
