        <h1><a name="FedizCXF-CXFPlugin%281.1SNAPSHOT%29"></a>CXF Plugin
(1.1 SNAPSHOT)</h1>
<p>The subproject Fediz purpose is to provide Single Sign On for Web Applications which
is independent of an underlying Web Services framework like Apache CXF. The Fediz plugins
for Tomcat, Jetty, etc. are independent of Apache CXF, whereas the Fediz IDP leverages the
capabilities of the CXF STS to issue SAML tokens with Claims information to build applications
which use Claims Based Authorization with all the benefits.</p>

<p>If the Fediz protected web application integrates with another application using
Web Services you need to bundle a Web Services framework like Apache CXF with your web application.
If it is required to support impersonation to call the Web Service, the security context of
the application server must be delegated to the Web Services stack thus it can make the Web
Service call on behalf of the browser user.</p>

<p>In release 1.1, the Fediz CXF plugin supports delegating the application server security
context (SAML token) to the STS client of CXF. CXF is then able to request a security token
for the target Web Service from the STS on behalf of the browser user. Prior to release 1.1,
this Java code had to be developed by the application developer.</p>

<p>It is required that one of the other Fediz plugins are deployed to WS-Federation
enable the application. After this step, the Fediz CXF plugin can be installed to integrate
the Web SSO layer with the Web Services stack of Apache CXF.</p>


<h3><a name="FedizCXF-Installation"></a>Installation</h3>
<p>It's recommended to use Maven to resolve the dependencies as illustrated in the the
example <tt>wsclientWebapp</tt>.</p>

<div class="code panel" style="border-style: solid;border-width: 1px;"><div class="codeHeader
panelHeader" style="border-bottom-width: 1px;border-bottom-style: solid;"><b>pom.xml</b></div><div
class="codeContent panelContent">
<pre class="theme: Default; brush: xml; gutter: false" style="font-size:12px; font-family:
ConfluenceInstalledFont,monospace;">
    &lt;dependency&gt;
        &lt;groupId&gt;org.apache.cxf.fediz&lt;/groupId&gt;
        &lt;artifactId&gt;fediz-cxf&lt;/artifactId&gt;
        &lt;version&gt;1.1.0&lt;/version&gt;
    &lt;/dependency&gt;
</pre>
</div></div>

<p>The example contains a README with instructions for building and deployment.</p>

<h3><a name="FedizCXF-Configuration"></a>Configuration</h3>
<p>Two configurations are required in <tt>web.xml</tt> to enable the <tt>FederationFilter</tt>
to cache the security context in the thread local storage and in the spring configuration
file <tt>applicationContext.xml</tt> to configure a callback handler to provide
the STS client the security context stored in the thread local storage. </p>

<div class="code panel" style="border-style: solid;border-width: 1px;"><div class="codeHeader
panelHeader" style="border-bottom-width: 1px;border-bottom-style: solid;"><b>web.xml</b></div><div
class="codeContent panelContent">
<pre class="theme: Default; brush: xml; gutter: false" style="font-size:12px; font-family:
ConfluenceInstalledFont,monospace;">
    &lt;filter&gt;
        &lt;filter-name&gt;FederationFilter&lt;/filter-name&gt;
        &lt;filter-class&gt;org.apache.cxf.fediz.core.servlet.FederationFilter&lt;/filter-class&gt;
    &lt;/filter&gt;

    &lt;filter-mapping&gt;
        &lt;filter-name&gt;FederationFilter&lt;/filter-name&gt;
        &lt;url-pattern&gt;/secure/*&lt;/url-pattern&gt;
    &lt;/filter-mapping&gt;
</pre>
</div></div>

<p>The <tt>FederationFilter</tt> is part of the library <tt>fediz-core</tt>.</p>

<div class="code panel" style="border-style: solid;border-width: 1px;"><div class="codeHeader
panelHeader" style="border-bottom-width: 1px;border-bottom-style: solid;"><b>applicationContext.xml</b></div><div
class="codeContent panelContent">
<pre class="theme: Default; brush: xml; gutter: false" style="font-size:12px; font-family:
ConfluenceInstalledFont,monospace;">
    &lt;bean id="delegationCallbackHandler"
        class="org.apache.cxf.fediz.cxf.web.ThreadLocalCallbackHandler" /&gt;

    &lt;jaxws:client id="HelloServiceClient" serviceName="svc:GreeterService"
        ...
        wsdlLocation="WEB-INF/wsdl/hello_world.wsdl"&gt;
        &lt;jaxws:properties&gt;
            &lt;entry key="ws-security.sts.client"&gt;
                &lt;bean class="org.apache.cxf.ws.security.trust.STSClient"&gt;
                    ...
                    &lt;property name="onBehalfOf" ref="delegationCallbackHandler" /&gt;
                    ...
                 &lt;/bean&gt;
            &lt;/entry&gt;
            &lt;entry key="ws-security.cache.issued.token.in.endpoint" value="false" /&gt;
        &lt;/jaxws:properties&gt;
    &lt;/jaxws:client&gt;

</pre>
</div></div>

<p>The <tt>ThreadLocalCallbackHandler</tt> is part of the library <tt>fediz-cxf</tt>.</p>

<p>If you have set the property <tt>ws-security.cache.issued.token.in.endpoint</tt>
to false, CXF will cache the issued token per security context dependent on the returned lifetime
element of the STS. When the cached token for the target web services is expired, CXF will
request a new token from the STS on-behalf-of the cached Fediz security context.</p>

<p>There is no special Java code required to get this functionality as illustrated in
the following code snippet:</p>

<div class="code panel" style="border-style: solid;border-width: 1px;"><div class="codeHeader
panelHeader" style="border-bottom-width: 1px;border-bottom-style: solid;"><b>FederationServlet.java</b></div><div
class="codeContent panelContent">
<pre class="theme: Default; brush: java; gutter: false" style="font-size:12px; font-family:
ConfluenceInstalledFont,monospace;">
    Greeter service = (Greeter)ApplicationContextProvider.getContext().getBean("HelloServiceClient");
    String reply = service.greetMe();
</pre>
