What it is?

A demo embedded application for a Camunda (rest + cockpit/tasklist) integrated with Spring Boot (Jersey2 + Undertow).

Spring Boot + Jersey 2 + Undertow:

Configure gradle correctly (include boot, and exclude tomcat)
Configure a ResourceConfig
Implement your resource: SampleResource

Camunda integration:

Include camunda dependencies.
Declare a SPI ProcessEngineProvider (see src/main/resources/META-INF/services)
Implement it: RestProcessEngineProvider
Configure the process engine: ProcessEngineSpringConfiguration
Implement your BPM / service class.

Camunda Rest + Cockpit integration:

Include webapp depedencies (note classes classifier):

compile("org.camunda.bpm:camunda-engine-rest:$camundaVersion:classes") compile("org.camunda.bpm.webapp:camunda-webapp:$camundaVersion:classes")
Repackage the Javascript/Html files in a webjar-like manner: camunda-webapp-webjar/build.gradle
Register all the Camunda servlets: CamundaWebAppInitializer

Tests:

Use REST-assured coz it rocks!

Production ready:

Add Spring boot actuator.
Configure Dropwizard metrics.
Expose JMX as HTTP with jolokia.
