Hi all,
In case anybody is interested in this: I created a maven pom today which builds a war overlay for quickly deploying "camunda BPM Standalone" on Heroku/Tomcat/Postgres. The build uses a small XSL stylesheet to add the heroku/postgres database values to the applicationContext.xml which comes with camunda's distribution. So it should be safe to use with future versions, too.
Basically you just need to clone the repo, issue a "heroku create" and then push everything to heroku. You find a bit more documentation here:
Many greetings and have nice weekend!
Martin.
