ryu.app.ws_topology and ryu.app.ofctl_rest are dependent (needed) on
ryu.app.gui_topology.gui_topology.
Thus the applications are loaded automatically.
How about the following? It should be loaded ryu.app.ws_topology and
ryu.app.ofctl_rest.
PYTHONPATH=. ./bin/ryu-manager --observe-links
ryu/app/gui_topology/gui_topology.py ryu/app/simple_switch.py
loading app ryu/app/gui_topology/gui_topology.py
loading app ryu/app/simple_switch.py
loading app ryu.app.rest_topology
loading app ryu.app.ws_topology <- (Here)
loading app ryu.app.ofctl_rest <- (Here)
loading app ryu.controller.ofp_handler
