{toc}

h1. HTTPS

Transport-level protection of JAX-RS endpoints can be managed by underlying Servlet containers, for example, see this [Tomcat SSL Configuration section|http://tomcat.apache.org/tomcat-6.0-doc/ssl-howto.html]. 

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}

If you also have a jaxrs:server endpoint declared in the above beans.xml, then make sure you have a 'depends-on' attribute set:

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

Once you have JAX-RS and Jetty HTTPS combined then you can get the application context initiated like this:

{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}

Having JAX-RS endpoints declared alongside CXF Jetty HTTPS configuration is only needed when an embedded Jetty container is used. If you have application WARs deployed into Tomcat or Jetty then please follow container-specific guides on how to set up SSL.

Please also see this [HTTPS-based 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 user authentication. Sometimes you might want to do the custom authentication instead. The easiest way to do this 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 policy = (AuthorizationPolicy)m.get(AuthorizationPolicy.class);
        policy.getUserName();
        policy.getPassword(); 
        return null;
    }

}
{code} 

A demo called {{samples\jax_rs\spring_security}} shows how to provide the authentication and authorization with the help of Spring Security.

Please see the [Security] section on how CXF Security interceptors can help. 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.

h1. Authorization


h1. WS-Trust integration


*SecurityManager and IllegalAccessExceptions*
h2. Validating BasicAuth credentials with STS

h1. Note about SecurityManager

If {{java.lang.SecurityManager}} is installed then you'll likely need to configure the trusted JAX-RS codebase with a 'suppressAccessChecks' permission for the injection of JAXRS context or parameter fields to succeed. For example, you may want to update a Tomcat [catalina.policy|http://tomcat.apache.org/tomcat-5.5-doc/security-manager-howto.html] with the following permission :

{code}
grant codeBase "file:${catalina.home}/webapps/yourwebapp/lib/cxf.jar" {
    permission java.lang.reflect.ReflectPermission "suppressAccessChecks";
};
{code}
