Create component
cd ~/workspace getTemplateForDirectory MODROOT_WS pyHelloComp cd pyHelloComp/src mkdir ws touch ws/__init__.py touch ws/HelloComponentImpl.py vim Makefile
We modify the Makefile for this component:
pyHelloComp/src/Makefile
... PY_PACKAGES = ws ...
We fill the component code as follows:
vim ws/HelloComponentImpl.py
pyHelloComp/src/ws/HelloComponentImpl.py
# Client stubs and definitions, such as structs, enums, etc.
import workshop
# Skeleton infrastructure for server implementation
import workshop__POA
# Base component implementation
from Acspy.Servants.ACSComponent import ACSComponent
# Services provided by the container to the component
from Acspy.Servants.ContainerServices import ContainerServices
# Basic component lifecycle (initialize, execute, cleanUp and aboutToAbort methods)
from Acspy.Servants.ComponentLifecycle import ComponentLifecycle
class HelloComponentImpl(workshop__POA.HelloComponent, ACSComponent, ContainerServices, ComponentLifecycle):
def __init__(self):
ACSComponent.__init__(self)
ContainerServices.__init__(self)
self._logger = self.getLogger()
def printHello(self):
print("Just printing 'Hello World!'")
return "Hello World!"
Compile component
export INTROOT=~/workspace/introot export PYTHONPATH=$INTROOT/lib/python/site-packages:/alma/ACS-2021AUG/ACSSW/lib/python/site-packages make all install
Add component to CDB
vim $ACS_CDB/CDB/MACI/Components/Components.xml
Add the following item:
Components.xml
<e Name="HelloWorldPython" Code="ws/HelloComponentImpl"
Type="IDL:acsws/workshop/HelloComponent:1.0"
Container="aragornContainer" ImplLang="py" />
Testing
Create client python file:
cd ~/workspace touch client.py vim client.py
We fill it as follow:
~/workspace/client.py
from Acspy.Clients.SimpleClient import PySimpleClient
client = PySimpleClient()
hc_py = client.getComponent("HelloWorldPython")
print(hc_py.printHello())
Run client:
python client.py
Example output:
... Hello World! ...
