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