   You need to add a persistence configuration to your classpath to  configure JPA to use Hibernate and the H2 database (or your own preference), called [path]_persistence.xml_
    in the META-INF directory, as shown below.
  -For more details on how to change this for your own configuration, we refer to the JPA and Hibernate documentation for more information.

  By default, the {PROCESS_ENGINE} does not save runtime data persistently.
  This means you can use the {PROCESS_ENGINE} completely without persistence (so not even requiring an in memory database) if necessary, for example for performance reasons, or when you would like to manage persistence yourself.
  It is, however, possible to configure the {PROCESS_ENGINE} to do use persistence by configuring it to do so.
  This usually requires adding the necessary dependencies, configuring a datasource and creating the {PROCESS_ENGINE} with persistence configured.

  This configuration file refers to a data source called "jdbc/jbpm-ds". If you run your application in an application server (such as JBoss AS), these containers typically allow you to easily set up data sources using some configuration (such as adding a data source configuration file in the deploy directory).  Please refer to your application server documentation to know how to do this.
  
  For example, if you're deploying to Wildfly, you can  create a data source by dropping a configuration file in the deploy directory,  for example:
