Description
Hi Radu,
Currently the CEP supports two types of consumers - File (mainly for
testing) and Rest (that push events to external REST service).
One option I can think of to solve your situation is to implement a REST
service that receives events from the CEP and sends it to your mobile app
in your preferable way.
I will be glad to hear your solution.

Subject: CEP GE question
Hi,
I have a question regarding PROTON.
My use case is the following:
I have an Android/iOS app which get sensor events (these would be the
producers).
I understand that I can push this events to the EPA using POST requests.
Then, some logic takes place and some output is generated.
Since it is unfeasible to run a web server on the phone, how can I receive
back the output (making the phone also a consumer) ?
Best,

In the GitHub you have a .zip file. It contains:
IBMProtonAuthoringTool.zip where you can find the two wars files of the
CEP authoring tool
IBMProtonOnWebServer.zip where you can find the two wars of the CEP engine

Thanks for the info.
I am having some trouble setting up PROTON.
The installation instructions talk about an installation package
containing 4 war files. Where is this installation package?
When I click on the "Download" tab, I do not see any deliverable, just a
GitHub url. If I clone that repo, I don't have 4 .war files, but some .zip
files, which do not contain any .war file.
Any thoughts?

If I send a POST request from the phone to the CEP, will I receive the
output as the request's response right away?

You should set a REST producer only if you want the CEP to pull events
from an external REST service.
If you want to send events to the CEP through REST you should NOT define a
REST producer.
Instead you just send events to the CEP using the CEP REST service as
described here:

Sorry for that message, I solved the error.
I have however the following issue:
I set up a REST url for the producer, but PROTON is trying to poll it.
What I want is PROTON to display a rest interface, to which I send the
POST request, how can I do that?
Best,
Radu

As I mentioned before there are 4 wars. Two for the engine and 2 for the
UI.
You need to drop the 4 into Tomcat's webapp directory.
You don't need the PROTON jar (it can be used if you want to run the CEP
as a stand alone Java engine, not on a server, without the REST services
support)

Thank you.
There is something else I don't understand:
I dropped a war file (and renamed it) into the tomcat's webapps directory.
I also clone the GitHub repo and launched the PROTON jar.
Are both this steps needed? Or am I misunderstanding something?
