The examples-servlet application demonstrate the capability that apex-pdp can be simply started as a servlet deployed in any application server (example - tomcat).
The examples-servlet war file can be found at following locations.
1) Inside a container where apex-pdp is installed - /opt/app/policy/apex-pdp/apex-pdp-package-full-${project.version}/war
2) Inside the tarball.gz distribution of apex-pdp - /war
Kindly follow the following steps to run apex-pdp servlet example war file.
1) Install a tomcat server (or any other web server of your choice).
2) Goto webapps folder under tomcat installation directory.
3) Copy the examples-servlet war file here.
4) Make sure you have given correct access permission to the war file to execute.
5) Goto bin directory of tomcat and start the server using appropriate script for windows/linux.
6) Open a browser window and type the following url - http://localhost:8080/examples-servlet-2.0.0-SNAPSHOT/apex/eventInput/Status
7) If everything is fine, you must see the following JSON in browser.
{
"INPUTS": "[FirstConsumer, SecondConsumer]",
"STAT": 1,
"POST": 0,
"PUT": 0
}
8) Open a rest client (example - Postman, ARC etc.) and make a http post request with following details.
Method: POST
URL: http://localhost:8080/examples-servlet-2.0.0-SNAPSHOT/apex/FirstConsumer/EventIn
Header: [{"key":"Content-Type","value":"application/json"}]
Body: {
"nameSpace": "org.onap.policy.apex.sample.events",
"name": "Event0100",
"version": "0.0.1",
"source": "test",
"target": "apex",
"TestSlogan": "Test slogan for External Event1",
"TestMatchCase": 0,
"TestTimestamp": 1469781869268,
"TestTemperature": 8071.559
}
9) If everything is fine, you must see the following response from server in your rest client.
Status: 200 OK
Body: {
"name": "Event0104",
"version": "0.0.1",
"nameSpace": "org.onap.policy.apex.sample.events",
"source": "Act",
"target": "Outside",
"TestActCaseSelected": 2,
"TestActStateTime": 1532960255194,
"TestDecideCaseSelected": 1,
"TestDecideStateTime": 1532960255114,
"TestEstablishCaseSelected": 3,
"TestEstablishStateTime": 1532960255085,
"TestMatchCase": 0,
"TestMatchCaseSelected": 1,
"TestMatchStateTime": 1532960255047,
"TestSlogan": "Test slogan for External Event1",
"TestTemperature": 8071.559,
"TestTimestamp": 1469781869268
}
10) Congratulations!!! you have successfully run examples-servlet application.
11) Try playing more by changing the json body content in http post request (Step-8) and fetching status from browser (Step-6).
Note - If not working, please check the IP, PORT & webapp context root (examples-servlet-2.0.0-SNAPSHOT) as it may be different.
