Currently Keycloak supports securing your web applications running inside [JBoss Fuse](http://www.jboss.org/products/fuse/overview/) or [Apache Karaf](http://karaf.apache.org/). It leverages Jetty8 adapter
as both JBoss Fuse 6 and Apache Karaf 3 are bundled with [Jetty8](http://eclipse.org/jetty/) server under the covers and Jetty is used for running various kinds of web applications.
* Security for classic WAR applications deployed on Fuse/Karaf with [pax-war extender](https://ops4j1.jira.com/wiki/display/ops4j/Pax+Web+Extender+-+War).
* Security for servlets deployed on Fuse/Karaf as OSGI services with [pax-whiteboard extender](https://ops4j1.jira.com/wiki/display/ops4j/Pax+Web+Extender+-+Whiteboard).
* Security for [Apache Camel](http://camel.apache.org/) Jetty endpoints running with [camel-jetty](http://camel.apache.org/jetty.html) component.
* Security for [Apache CXF](http://cxf.apache.org/) endpoints running on their own separate [Jetty engine](http://cxf.apache.org/docs/jetty-configuration.html).
Supports both securing JAX-RS and JAX-WS endpoints.
* Security for [Apache CXF](http://cxf.apache.org/) endpoints running on default engine provided by CXF servlet on [http://localhost:8181/cxf](http://localhost:8181/cxf) . NOTE: Actually It's better and
more secure to use the separate Jetty Engine instead of the default one. The default engine works fine, but I would recommend the separate one.
* **customer-app-fuse** A WAR application that is deployed with [pax-war extender](https://ops4j1.jira.com/wiki/display/ops4j/Pax+Web+Extender+-+War)
* **product-app-fuse** A servlet application deployed with [pax-whiteboard extender](https://ops4j1.jira.com/wiki/display/ops4j/Pax+Web+Extender+-+Whiteboard)
* **cxf-jaxws** [Apache CXF](http://cxf.apache.org/) JAX-WS endpoint running on separate Jetty engine on [http://localhost:8282/PersonServiceCF](http://localhost:8282/PersonServiceCF).
The product-app-fuse invokes the endpoint to get data.
* **camel** [Apache Camel](http://camel.apache.org/) endpoint running on separate Jetty engine on [http://localhost:8383/admin-camel-endpoint](http://localhost:8383/admin-camel-endpoint).
The customer-app-fuse invokes the endpoint to get data.
* **cxf-jaxrs** [Apache CXF](http://cxf.apache.org/) JAX-RS endpoint running on default Jetty on [http://localhost:8181/cxf/customerservice](http://localhost:8181/cxf/customerservice).
The customer-app-fuse invokes the endpoint to get data
Running of demo consists of 2 steps. First you need to run separate Keycloak server and then Fuse/Karaf server with the applications
* Run external instance of Keycloak server on WildFly . It's easiest to run and download Keycloak standalone server. Fuse demo suppose that server is running on [http://localhost:8080/auth](http://localhost:8080/auth)
* Import realm `demo` from the file testrealm.json on `examples/fuse/testrealm.json` . See [here](../demo-template/README.md#step-3-import-the-test-realm)
You just need to download and run JBoss Fuse and then run those commands from the karaf terminal to install the needed features and Keycloak fuse demo (Replace Keycloak versions with the current Keycloak version number):
After that you can test running on [http://localhost:8181/customer-portal](http://localhost:8181/customer-portal) and login as "bburke@redhat.com" with password "password". Customer-portal is able to
receive the response from the endpoints provided by `cxf-jaxrs` and `camel` applications. Note that camel endpoint is available just for users with role `admin`
in this demo, so "bburke@redhat.com" can't access it. You may login as "admin" with password "password" in order to invoke camel endpoint.
From [http://localhost:8181/product-portal](http://localhost:8181/product-portal) you will see servlet endpoint, which invokes JAX-WS provided by `cxf-jaxws` application.
Note that this demo also secures whole default CXF endpoint on [http://localhost:8181/cxf](http://localhost:8181/cxf) hence every application running under it is secured too.
Demo is using Apache camel and Apache CXF, which are not in standalone Karaf by default. So you will need to install feature repositories for both of them.
Next step is to add feature repository for main set of Keycloak karaf features and for the demo. Once all feature URLs are added, you just need to install `keycloak-fuse-example` feature,
which automatically installs all other needed stuff.
Once you run Apache Karaf, you need to run these commands from Karaf console (Make sure to replace keycloak versions in the example with actual Keycloak version):
Securing your applications on JBoss Fuse 6.1 is a bit more tricky. There is bug [https://ops4j1.jira.com/browse/PAXWEB-666](https://ops4j1.jira.com/browse/PAXWEB-666)
, which doesn't easily allow to secure default Jetty engine on [http://localhost:8181](http://localhost:8181) as it's not possible to inject
custom Jetty authenticator provided by Keycloak Jetty adapter into underlying Jetty server. Hence first step is to upgrade pax-web
version from default 3.0.6 to newer 3.1.2 . Then you need to "refresh" cxf feature too. Final step is to install "keycloak-fuse-example" feature.
Most of the steps should be understandable from testing and understanding the demo. Basically all mentioned applications require to
inject Keycloak Jetty authenticator into underlying Jetty server . The steps are bit different according to application type.
**Classic WAR application** - Take a look at `customer-portal-app` for inspiration. The needed steps are:
* Declare needed constraints in `/WEB-INF/web.xml`
* Add `jetty-web.xml` file with the authenticator to `/WEB-INF/jetty-web.xml` and add `/WEB-INF/keycloak.json` with your Keycloak configuration
* Make sure your WAR imports `org.keycloak.adapters.jetty` and maybe some more packages in MANIFEST.MF file in header `Import-Package`. It's
recommended to use maven-bundle-plugin similarly like Fuse examples are doing, but note that "*" resolution for package doesn't import `org.keycloak.adapters.jetty` package
as it's not used by application or Blueprint or Spring descriptor, but it's used just in jetty-web.xml file.
**Servlet web application deployed by pax-whiteboard-extender** - Take a look at `product-portal-app` for inspiration. The needed steps are:
Example `product-portal-app` declares this in `OSGI-INF/blueprint/blueprint.xml` . Note that your servlet needs to depend on it.
* Steps 2,3 are same like for classic WAR
**Apache camel application** - You can secure your Apache camel endpoint using [camel-jetty](http://camel.apache.org/jetty.html) endpoint by adding securityHandler with KeycloakJettyAuthenticator and
proper security constraints injected. Take a look at `OSGI-INF/blueprint/blueprint.xml` configuration in `camel` application on example of how it can be done.
**Apache CXF endpoint** - It's recommended to run your CXF endpoints secured by Keycloak on separate Jetty engine. Application `cxf-ws` is using separate endpoint on
[http://localhost:8282](http://localhost:8282) . All the important configuration is declared in cxf-jaxws app in `META-INF/spring/beans.xml` .
**Builtin web applications** - Some services automatically come with deployed servlets on startup. One of such examples is CXF servlet running on
[http://localhost:8181/cxf](http://localhost:8181/cxf) context. Securing such endpoints is quite tricky. The approach, which Keycloak is currently using,
is providing ServletReregistrationService, which undeploys builtin servlet at startup, so you are able to re-deploy it again on context secured by Keycloak.
You can see the `OSGI-INF/blueprint/blueprint.xml` inside `cxf-jaxrs` project, which adds JAX-RS "customerservice" endpoint and more importantly, it secures whole `/cxf` context.
As a side effect, all other CXF services running on default CXF HTTP destination will be secured too. Once you uninstall feature "keycloak-fuse-example" the
original unsecured servlet on `/cxf` context is deployed back and hence context will become unsecured again.
