 ~~Title: Custom REST service registration~~
 JVx already has [[jvx:common:util:rest|REST services]] for action calls, data access an administration. Sometimes it's necessary to offer custom REST services for an application. Sure, you could create a simple action in your application and an action can be called with standard REST services, but this requires application authentication. If you have a different use-case for your REST service it's also possible to create your own REST service without using different libraries.

 to your deployment descriptor (web.xml).
+To use your services, simply send ''GET'' or ''POST'' requests, e.g.

+@Test
+public void testGet() throws Exception
+{
+    ClientResource cres = new ClientResource(getBaseURL() + "_user/healthCheck");

+The user-zone is per default ''_zone'' (e.g. **http://localhost/AppContext/services/rest/_user/healthCheck**). If you want another zone name, simply add a parameter to the servlet mapping in deployment descriptor (web.xml):
+<file xml>
+<servlet>
+  <servlet-name>RestletServlet</servlet-name>
+  <servlet-class>com.sibvisions.rad.server.http.rest.RESTServlet</servlet-class>
+  <init-param>
+    <param-name>zone.user</param-name>
+    <param-value>uzone</param-value>
+  </init-param>
+</servlet>
+</file>
+The zone name is now ''uzone'' (e.g. **http://localhost/AppContext/services/rest/uzone/healthCheck**).
+The complete source code is available [[https://sourceforge.net/p/jvx/code/HEAD/tree/trunk/java/server/tomcat/|here]].
+In this document, we registered User services. It's also possible to register custom services as [[jvx:common:util:rest#administration|Admin services]]. The difference is that it's possible to [[jvx:server:security:rest_services_disable|en/disable admin services]] by name.
