===== Securing a servlet deployed as an OSGI Service
|
|
|
|
You can use this method if you have a servlet class inside your OSGI bundled project that is not deployed as a classic WAR application. Fuse uses Pax Web Whiteboard Extender to deploy such servlets as web applications.
|
|
|
|
.Procedure
|
|
|
|
. {project_name} provides `org.keycloak.adapters.osgi.undertow.PaxWebIntegrationService`, which allows configuring authentication method and security constraints for your application. You need to declare such services in the `OSGI-INF/blueprint/blueprint.xml` file inside your application. Note that your servlet needs to depend on it.

An example configuration:

|
|
You might need to have the `WEB-INF` directory inside your project (even if your project is not a web application) and create the `/WEB-INF/keycloak.json` file as described in the <<_fuse7_adapter_classic_war,Classic WAR application>> section.
|
|
Note you don't need the `web.xml` file as the security-constraints are declared in the blueprint configuration file.
|
|
|
|
. Contrary to the Fuse 6 adapter, there are no special OSGi imports needed in MANIFEST.MF.
