I want to use the camunda rest api (local), but I realy can't figure out how to set up the environment... .
First I downloaded the tomcat distribution from here (V. 7.2.0) and the prepackaged eclipse with BPMN 2.0 Modeler from here.
I modelled a process, startet the server (start-camunda.bat) and deployed it (copied .war to ...camunda\server\apache-tomcat-7.0.50\webapps).
It went well on local tasklist http://localhost:8080/camunda/app/tasklist/default/#/login and cockpit http://localhost:8080/camunda/app/cockpit/default/).
I also downloaded the engine-rest from "Maven Nexus Server" (Install the REST API web application). Now, if I call the engine (http://localhost:8080/engine-rest/engine), I got the following .json: [{"name":"default"}]
What to do next? I realy don't know (I'm new in camunda...)
Answer
Your setup seems to be fine. But please note that the camunda REST API is a backend which you can access with a client. Currently there doesn't exists a camunda Java REST client. So you have to implement it by your self. If you are aware of that a good starting point is the camunda REST documentation. Besides Java there exists a Javascript SDK which you could use to access the REST API.
