Additionally CXF provides support for configuring endpoints which depend on embedded Jetty. CXF JAX-RS clients can also be configured to support SSL. 
 
h2. Configuring endpoints

JAX-RS endpoints using embedded Jetty can rely on the configuration like this one:

{code:xml}
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:http="http://cxf.apache.org/transports/http/configuration"
       xmlns:httpj="http://cxf.apache.org/transports/http-jetty/configuration"
       xmlns:sec="http://cxf.apache.org/configuration/security"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans                 http://www.springframework.org/schema/beans/spring-beans.xsd
        http://cxf.apache.org/transports/http/configuration         http://cxf.apache.org/schemas/configuration/http-conf.xsd
        http://cxf.apache.org/transports/http-jetty/configuration   http://cxf.apache.org/schemas/configuration/http-jetty.xsd
        http://cxf.apache.org/configuration/security                http://cxf.apache.org/schemas/configuration/security.xsd">


    <httpj:engine-factory id="port-9095-tls-config">
        <httpj:engine port="9095">
            <httpj:tlsServerParameters>
                <sec:keyManagers keyPassword="password">
	            <sec:keyStore type="JKS" password="password" 
	                file="src/test/java/org/apache/cxf/systest/http/resources/Bethal.jks"/>
	        		</sec:keyManagers>
	        		<sec:trustManagers>
	            	<sec:keyStore type="JKS" password="password"
	                file="src/test/java/org/apache/cxf/systest/http/resources/Truststore.jks"/>
	     		</sec:trustManagers>
            </httpj:tlsServerParameters>
        </httpj:engine>
    </httpj:engine-factory>
</beans>
{code}

If you use JAXRSServerFactoryBean to create and start JAX-RS endpoints from the code then the above configuration can be utilized like this:
{code:java}

JAXRSServerFactoryBean bean = new JAXRSServerFactoryBean();
SpringBusFactory bf = new SpringBusFactory();
Bus bus = bf.createBus("configuration/beans.xml");
bean.setBus(bus);
bean.setAddress("http://localhost:9095/rest");
bean.setServiceClass(CustomerService.class);
{code}

{code:xml}
<jaxrs:server serviceClass="CustomerService.class" address="http://localhost:9095/rest"
   depends-on="port-9095-tls-config"/>
{code} 

Once you have 

{code:java}
public class Server {

    public void main(String[] args) throws Exception {
        Bus busLocal = new SpringBusFactory().createBus("configuration/beans.xml");
        BusFactory.setDefaultBus(busLocal);
        new Server();
        Thread.sleep(60000);
    }
}
{code}

final String address = "http://localhost:9095/rest";
final String configLocation;

WebClient client = WebClient.create(address, configLocation);
// or
BookStore proxy = JAXRSClientFactory.create(address, configLocation, BookStore.class);

public class AuthenticationHandler implements ContainerRequestFilter {

    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {
        String authorization = requestContext.getHeaderString("Authorization");
        String[] parts = authValues.authorization(" ");
        if (parts.length != 2 || !"Basic".equals(parts[0])) {
            requestContext.abortWith(createFaultResponse());
            return;
        }
        
        String decodedValue = null;
        try {
   demo|http://svn.apache.org/repos/asf/cxf/trunk/distribution/src/main/release/samples/jax_rs/basic_https/] in the CXF distribution.

Additionally check the [CXF Jetty Configuration|http://cxf.apache.org/docs/jetty-configuration.html] section.

h2. Configuring clients

Secure HTTPConduits for CXF JAX-RS proxies and WebClients can be configured as described in this [section|http://cxf.apache.org/docs/client-http-transport-including-ssl-support.html]. 

For example, check this [configuration file|http://svn.apache.org/repos/asf/cxf/trunk/distribution/src/main/release/samples/jax_rs/basic_https/src/main/resources/ClientConfig.xml]. Endpoint addresses used by proxies or clients have to match the pattern used in the HTTPConduit configuration.

The configuration file can be referenced during the proxy or WebClient creation:
{code:java}
final Stribg address = "http://localhost:9095/rest";
final String configLocation;

WebClient client = WebClient.create(address, configLocation);
// or
BookStore proxy = JAXRSClientFactory.create(address, configLocation, BookStore.class);
{code}

HTTPConduits can also be 'bound' to proxies or WebClients using expanded QNames. Please see this [section|http://cxf.apache.org/docs/jax-rs-client-api.html#JAX-RSClientAPI-ConfiguringanHTTPConduitfromSpring] for more information.

h1. Authentication

It is often containers like Tomcat or frameworks like Spring Security which handle the user authentication. Sometimes you might want to do the custom authentication instead. CXF HTTP Transport adds decoded Basic Authentication credentials into an instance of AuthorizationPolicy extension and sets it on the current message. Thus the easiest way is to register a custom invoker or {{RequestHandler}} filter which will extract a user name and password like this:

{code:java}
public class AuthenticationHandler implements RequestHandler {

    public Response handleRequest(Message m, ClassResourceInfo resourceClass) {
        AuthorizationPolicy  policydecodedValue = (AuthorizationPolicy)m.get(AuthorizationPolicy.classnew String(Base64Utility.decode(parts[1]));
        String} usernamecatch = policy.getUserName();(Base64Exception ex) {
        String  password = policyrequestContext.getPasswordabortWith(createFaultResponse());
 
        if (isAuthenticated(username, password)) {return;
        }
    // let request to continue
    String[] namePassword = decodedValue.split(":"); 
        if  return null;(isAuthenticated(namePassword[0], namePassword[1])) {
        } else {
  // let request to continue
       // authentication} failedelse {
            return Response.status(401).build();   
        }
    }

}
{code} 

One other thing you may want to do, after authenticating a user, is to initialize org.apache.cxf.security.SecurityContext with Principals representing the user and its roles (if available).

If you prefer using Spring Security then see how the authentication is handled in a [spring-security|http://svn.apache.org/repos/asf/cxf/trunk/distribution/src/main/release/samples/jax_rs/spring_security] demo.

Next, please see the [Security] section on how CXF Security interceptors can help. 

Additionally check this [blog entry|http://sberyozkin.blogspot.com/2010/12/authentication-and-authorization-cxf.html] for more information on how CXF JAX-RS wraps the CXF security interceptors with helper filters.

For example, see how a JAX-RS filter can be used to wrap CXF JAASLoginInterceptor:

{code:xml}
// authentication failed, request the authetication, add the realm name if needed to the value of WWW-Authenticate 
            requestContext.abortWith(Response.status(401).header("WWW-Authenticate", "Basic").build());
        }
    }
    private Response createFaultResponse() {
        return Response.status(401).header("WWW-Authenticate", "Basic realm=\"service.com\"").build();
    }
 }

<jaxrs:server address="/jaas">
    <jaxrs:serviceBeans>
        <bean class="org.apache.cxf.systest.jaxrs.security.SecureBookStoreNoAnnotations"/>
    </jaxrs:serviceBeans>		   
    <jaxrs:providers>
        <ref bean="authenticationFilter"/>
    </jaxrs:providers>
  </jaxrs:server>
  
  <bean id="authenticationFilter" class="org.apache.cxf.jaxrs.security.JAASAutheenticationFilterJAASAuthenticationFilter">
        <!-- Name of the JAAS Context -->
        <property name="contextName" value="BookLogin"/>
        <!-- Hint to the filter on how to have Principals representing users and roles separated 
             while initializing a SecurityContext -->
        <property name="rolePrefix" value="ROLE_"/>
        
        <property name="redirectURI" value="/login.jsp"/>
  </bean>
{code}

 

h1. Authorization

It is often containers like Tomcat or frameworks like Spring Security which handle user authorization, similarly to the way the authentication is handled.

CXF also provides two interceptors which make it easy to enforce authorization decisions, as described in the [Security] section.
CXF JAX-RS SimpleAuthorizingFilter can be used to wrap those interceptors and return 403 in case of failures:

{code:xml}
<jaxrs:server address="/jaas">
    <jaxrs:serviceBeans>
        <bean class="org.apache.cxf.systest.jaxrs.security.SecureBookStoreNoAnnotations"/>
    </jaxrs:serviceBeans>		   
    <jaxrs:providers>
        <ref bean="authorizationFilter"/>
    </jaxrs:providers>
  </jaxrs:server>
  
  <bean id="authorizationFilter" class="org.apache.cxf.jaxrs.security.SimpleAuthorizingFilter">
        <property name="methodRolesMap" ref="rolesMap"/>
  </bean>
  
  <util:map id="rolesMap">
     <entry key="getThatBook" value="ROLE_BOOK_OWNER"/>
     <entry key="getBook" value="ROLE_BOOK_OWNER"/>
  </util:map>
{code}
