Hi,
I tried to find a way to send message from Google app engine to local application.
Here is my case, I have a servlet running in the GAE and a daemon application run local linux machine. Sometimes I need the servlet notify the local daemon to run some tasks immediately.
Not sure whether a way to do that? Email is not a option.
What I found now is
1. GCM/FCM support mobile device/web app but doesn't support windows/linux application.
2. Google app engine doesn't support listen. So I can not create connection between local application and GAE servlet. Also the daemon is under firewall and can not listen either.
Are there any other way to achieve it?
Thanks
