13  * EJB specific workflow context.
14  * The default implementation is to get the caller principal from the
15  * container's SessionContext. If different behaviour is desired, this
16  * class can be subclassed with whatever custom logic in place to look
17  * up the caller. This can be done by specifying a <code>workflowContext</code>
18  * property in the ejb persistence store's properties in osworkflow.xml.
19  * The value of this properly should be the classname of the WorkflowContext
20  * to use.
