Method Summary public  void ejbActivate()      The activate method is called when the instance is activated from its "passive" state. public  Integer ejbCreate()      Create an new instance. public  Integer ejbFindByPrimaryKey(Integer pk)      Find the ConfigurationBean. Only one instance of this bean exists. public  void ejbLoad()      This method loads additional configuration data from the database. public  void ejbPassivate()      The passivate method is called before the instance enters the "passive" state. public  void ejbPostCreate()      Called after creating a new instance. public  void ejbRemove()      A container invokes this method before it ends the life of the session object. public  void ejbStore()      This method saves modified configuration data in the database. public  de.danet.an.workflow.omgcore.WfActivity findActivity(String key)      Find the activity with the given key. public  void readConfiguration()      This Method reads the configuration-files and updates the parameters. public  void setEntityContext(EntityContext context)      Set the associated entity context. public  void unsetEntityContext()      Unset the associated entity context. public  String workflowEngineInstanceKey()      Returns an installation id for the component. Method Detail ejbActivate public void ejbActivate() throws EJBException(Code) The activate method is called when the instance is activated from its "passive" state. The instance should acquire any resource that it has released earlier in the ejbPassivate() method. This method gets the primary key from container. See Also:   javax.ejb.EntityBean ejbCreate public Integer ejbCreate() throws CreateException, EJBException(Code) Create an new instance. Not needed. primary key of the bean throws:   CreateException - Throws if the ProcessDirectoryBean can notbe create. throws:   EJBException - Throws on any error except. ejbFindByPrimaryKey public Integer ejbFindByPrimaryKey(Integer pk) throws FinderException(Code) Find the ConfigurationBean. Only one instance of this bean exists. The primary key is allways the integer value 0. Parameters:   pk - The primary key of the bean The primary key. throws:   FinderException - (ObjectNotFoundException)if no activity found. ejbLoad public void ejbLoad() throws EJBException(Code) This method loads additional configuration data from the database. Note that most configuration data is read in ConfigurationEJB.ejbActivate ejbActivate() . throws:   EJBException - if an SQLException occurs. ejbPassivate public void ejbPassivate() throws EJBException(Code) The passivate method is called before the instance enters the "passive" state. The instance should release any resources that it can re-acquire later in the ejbActivate() method. See Also:   javax.ejb.EntityBean ejbPostCreate public void ejbPostCreate() throws CreateException(Code) Called after creating a new instance. throws:   CreateException - if the activity can not be create. ejbRemove public void ejbRemove() throws RemoteException, EJBException(Code) A container invokes this method before it ends the life of the session object. This happens as a result of a client's invoking a remove operation, or when a container decides to terminate the session object after a timeout. See Also:   javax.ejb.EntityBean ejbStore public void ejbStore() throws EJBException(Code) This method saves modified configuration data in the database. throws:   EJBException - if an SQLException occurs. findActivity public de.danet.an.workflow.omgcore.WfActivity findActivity(String key) throws NoSuchActivityException(Code) Find the activity with the given key. This method really has no logical association with the configuration. It must however be provided by an entity bean. See de.danet.an.workflow.ejbs.admin.ActivityFinderthe description of ActivityFinder for details. Parameters:   key - the activity's key. the activity found. throws:   NoSuchActivityException - if key is invalid. readConfiguration public void readConfiguration() throws IOException(Code) This Method reads the configuration-files and updates the parameters. throws:   IOException - if an IO Error occurs. setEntityContext public void setEntityContext(EntityContext context) throws EJBException(Code) Set the associated entity context. The container calls this method after the instance creation. See Also:   javax.ejb.EntityBean Parameters:   context - - A SessionContext interface for the instance throws:   EJBException - on any error. unsetEntityContext public void unsetEntityContext() throws EJBException(Code) Unset the associated entity context. See Also:   javax.ejb.EntityBean workflowEngineInstanceKey public String workflowEngineInstanceKey()(Code) Returns an installation id for the component. The id remains the same until the database is re-created. an installation id Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
