ServiceHandler

Identifier:
org.eclipse.rap.ui.serviceHandler

Since:
RAP 1.3

Description:
A service handler can be used to process custom requests, e.g. to deliver files, images or other content to the client. Service handlers are called in the user's session scope, i.e. they can access session information. They can be implemented like servlets, i.e. they can access headers and parameters from the request object and write the result into the reponse writer or output stream. A service handler can be accessed by a URL with a specific parameter. This URL can be obtained from RWT.getServiceManager().getServiceHandlerUrl( "download" )

  <serviceHandler
      class="org.eclipse.rap.ui.impl.ServiceHandler1"
      id="myHandler1">
  </serviceHandler>
  <serviceHandler
      class="org.eclipse.rap.ui.ServiceHandler2"
      id="myHandler2">
  </serviceHandler>
</extension>
