Start a GAS app from GWA

The runOnServer front call allows you to start an application via the Genero Application Server (GAS) from a Genero Web application (GWA).

A runOnServer call in GWA follows the same basic design as in Genero Mobile for iOS (GMI) and Android™ (GMA), but there are a few important differences to note:

  1. First, in GWA both RUN and RUN ... WITHOUT WAITING may be used in any combination in the application being called by runOnServer; there is no restriction that forces one or the other. All combinations to run multiple applications server side are possible.
  2. Second, the runOnServer front call ends when all server side applications which were started by the runOnServer application are terminated in addition to the application itself. So all applications started with RUN ... WITHOUT WAITING need to be terminated in addition to the runOnServer application.
Finally, when supplying the GAS URL argument in GWA you may omit the full origin (for example, http://host:port) and use a simple path such as /ua/r/simple:
CALL ui.Interface.frontCall("mobile","runonserver",["/ua/r/simple"],[])

If you use a full origin URL, ensure you use the same origin as the GWA application which invokes the runOnServer call; otherwise, you will encounter an error. Both the GWA application URL and the runOnServer application URL must have the same origin.

In contrast, GMI/GMA cannot omit the origin because the native mobile app always runs from a different origin.
