    You can use HttpClient.

    Refer below URL:

    Yes - but why not implement a service (as opposed to a Servlet) then you can use @Reference annotation from within your custom step to invoke the Java logic.

      Based on your project's design and requirements whatever you choose to use (either servlet or service or just a component), the underlying logic would primarily work in same manner -  Get hold of server's runmode and process your custom code.

      To get the run mode in server side code -

      Slice-CQ/WcmModeModel.java at master · Cognifide/Slice-CQ · GitHub

      or use

      final WCMMode mode = WCMMode.fromRequest(request);

      if (null == mode || WCMMode.DISABLED.equals(mode)) { // do something }

      *you would find WCMMode in uber-jar

      Create your workflow, register it and use WCMMode to excute it only on publish server. Once everything is done, configure this workflow step in your custom workflow.

      Example -

      Hope that helps.
