No process engine found. camunda Webapp cannot work without a process engine

Question

When I set up a camunda BPMN platform, I got the following error

HTTP Status 500 - org.camunda.bpm.webapp.impl.IllegalWebAppConfigurationException: No process engine found. camunda Webapp cannot work without a process engine

Confirming that the both the '/camunda' and '/engine-rest' is deployed and running in Tomcat.

But /engine-rest returns 404 with following error.

Please help!.

Answer 1

You need to configure the shared process engine for your server as described in https://docs.camunda.org/manual/7.5/installation/full/tomcat/manual/#add-bpm-platform-xml

Answer 2

Have added bpm-platform.xml to '/conf'

<?xml version="1.0" encoding="UTF-8"?>
