Hi,

You can have a look at an exemple in eXo Social:

The service: http://svn.exoplatform.org/projects/social/trunk/application/rest/src/main/java/org/exoplatform/social/services/rest/AppsRestService.java

To deploy your service, you need to add configuration as done in this exemple:

http://svn.exoplatform.org/projects/social/trunk/application/rest/src/main/java/conf/portal/configuration.xml

I wrote a webservice in groovy few days ago that access the organisation service, you can easily convert it to java:

import javax.ws.rs.Path
import javax.ws.rs.GET
import javax.ws.rs.PathParam
import org.exoplatform.container.PortalContainer
import org.exoplatform.services.organization.OrganizationService
import org.exoplatform.container.component.RequestLifeCycle

@Path("/test")
public class Demo  {
  @GET
  @Path("/demoGroup")
  public String demoGroup() {
    def pc = PortalContainer.getInstance()
    RequestLifeCycle.begin(pc);
    try {
        def organizationService  = pc.getComponentInstanceOfType(OrganizationService.class)
        def groupHandler  = organizationService.getGroupHandler()
        def group = groupHandler.findGroupById("/Platform")
        ...
    } finally {
        RequestLifeCycle.end();
    }
  }
}

I hope it helps, let me know,

Yes, you need to initialize the RequestLifeCycle even if you are not in the portal context. Some services such as the OrganisationService need this initialization to work properly. Hopefully it will be done for you in a later version of GateIn so you will not have to care about it (EXOJCR-728) but until then it's required.
