Burkhard Vogel updated JBRULES-3098:
------------------------------------

    Attachment: ServiceLoader.java


implemetation and documentation from org.jboss.bpm.console.server.util package: 

   /**
    * This method uses the algorithm below using the JAXWS Provider as an example.
    *
    * 1. If a resource with the name of META-INF/services/javax.xml.ws.spi.Provider exists, then
    * its first line, if present, is used as the UTF-8 encoded name of the implementation class.
    *
    * 2. If the ${java.home}/lib/service-loader.properties file exists and it is readable by the
    * java.util.Properties.load(InputStream) method and it contains an entry whose key is
    * javax.xml.ws.spi.Provider, then the value of that entry is used as the name of the implementation class.
    *
    * 3. If a system property with the name javax.xml.ws.spi.Provider is defined, then its value is used
    * as the name of the implementation class.
    *
    * 4. Finally, a default implementation class name is used.

> Implementations of services like the SystemEventListenerService for instance are hard coded into the Drools code base. It recommendable to change thto a more customizable friendly approach, using a schema applied by the ServiceLoader from the org.jboss.bpm.console.server.util package (bpm-console project). By this method custom implementation to service providers do not need changes to the general code base.
