Found a solution here: [Flowable-custom-context.xm is too bad as configuration sample!](https://forum.flowable.org/t/flowable-custom-context-xm-is-too-bad-as-configuration-sample/1415)  
But didn’t work for me.

Also tried this: [How to configure flowable-rest.war using JNDI](https://forum.flowable.org/t/how-to-configure-flowable-rest-war-using-jndi/446)  
But no luck.

Ummm… am I missing something major? Why is it so hard to start the REST service with the default (supplied) config?
