/**
 * 

Prerequisites

*

* System properties that must be set: *

    *
  • openejb.home -> catalina.home *
  • openejb.base -> catalina.base *
  • tomee.war -> $tomee.war *
  • tomcat.version if not set *
  • tomcat.built if not set *
*

*

Integration Actions

*

*

    *
  • Setup ServiceJar: set openejb.provider.default -> org.apache.tomee * We therefore will load this file: META-INF/org.apache.openejb.tomcat/service-jar.xml *
  • Init SystemInstance and OptionsLog *
  • *
  • *
*
