Running the application

Once the application's launched we can play with it:


launcher> list
sk
launcher> list sk
  Facet: org.jtrix.facets1.service.common.IConsoleFacet
sk.quit - Shut down the application
sk.list-managers - Show all managers and their nodes
sk.list-workers - Show all workers and their nodes
sk.get-warrant - <type> [<service-data>] Get refreshed warrant
sk.set-manager-redundancy - <min> <max> Set the manager redundancy
sk.list-management-state - Display the management state
launcher> dump $sk skadmin.xml
launcher> bw=`sk.get-warrant skeleton`
launcher> connect skbasic $bw

launcher> skbasic.getMessage
Hello, skeleton plugin world
launcher> echo $skbasic
<<warrant>>
launcher> dump $bw skbasic.xml
launcher> quit

After launching we are connected automatically to the admin service, which we set in our manager netlet code. From here we generate a warrant for the consumer-level skeleton service (which we also defined in our code, and plugged in remotely). Then we connect to that service. At this point we are connected to both services, and we get the message from the skeleton service. Finally we dump our warrant into a file so we can use it again, or give it to someone else.

All this is just an example. The rest of this document explains the principles behind this application and therefore how to write our own larger ones.
