org.appng.core.controller.handler.ServiceRequestHandler

All Implemented Interfaces:

RequestHandler

public class ServiceRequestHandler
extends Object
implements RequestHandler

A RequestHandler which handles HttpServletRequests for different types of services.
The schema for a complate path to a service is

<site-domain>/<service-path>/<site-name>/<application-name>/<service-type/<service-name>/<additional-params>

The service-path is configurable, see SiteProperties.SERVICE_PATH.
Supported service-types are:

• webservice
  Used for calling a Webservice or AttachmentWebservice.
  Example:
  • http://localhost:8080/service/manager/appng-manager/webservice/logViewer<get-params>
• datasource
  Used for calling a datasource provided by a Application.
  Provides different formats: json,xml and html.
  Examples:
  • http://localhost:8080/service/manager/appng-manager/datasource/xml/sites
  • http://localhost:8080/service/manager/appng-manager/datasource/json/sites
  • http://localhost:8080/service/manager/appng-manager/datasource/html/sites
• action
  Used for calling an action provided by a Application.
  Provides different formats: json,xml and html.
  Examples:
  • http://localhost:8080/service/manager/appng-manager/action/xml/siteEvent/create?form_action=create
  • http://localhost:8080/service/manager/appng-manager/action/json/siteEvent/create?form_action=create
  • http://localhost:8080/service/manager/appng-manager/action/html/siteEvent/create?form_action=create
• soap
  Used for calling a SoapService provided by a Application.
  Example (GET for the wsdl):
  • http://localhost:8080/service/manager/appng-demoapplication/soap/PersonService/PersonService.wsdl
  POST for the SOAP-Request:
  • http://localhost:8080/service/manager/appng-demoapplication/soap/PersonService
• rest
  Used for addressing a RestController offered by an Application
  Example:
  • http://localhost:8080/service/manager/appng-manager/rest/sites
  • http://localhost:8080/service/manager/appng-manager/rest/site/1
