Method Detail

getConnection

public javax.jms.Connection getConnection()
                                   throws javax.jms.JMSException,
                                          javax.naming.NamingException

---

setConnection

public void setConnection(javax.jms.Connection connection)

---

getSession

public javax.jms.Session getSession()
                             throws javax.jms.JMSException,
                                    javax.naming.NamingException

---

setSession

public void setSession(javax.jms.Session session)

---

getProducer

public javax.jms.MessageProducer getProducer()
                                      throws javax.jms.JMSException,
                                             javax.naming.NamingException

---

setProducer

public void setProducer(javax.jms.MessageProducer producer)

---

close

public void close()

Description copied from interface: org.apache.log4j.Appender

Release any resources allocated within the appender such as file handles, network connections, etc.

It is a programming error to append to a closed appender.

---

requiresLayout

public boolean requiresLayout()

Description copied from interface: org.apache.log4j.Appender

Configurators call this method to determine if the appender requires a layout. If this method returns true, meaning that layout is required, then the configurator will configure an layout using the configuration information at its disposal. If this method returns false, meaning that a layout is not required, then layout configuration will be skipped even if there is available layout configuration information at the disposal of the configurator..

In the rather exceptional case, where the appender implementation admits a layout but can also work without it, then the appender should return true.

---

activateOptions

public void activateOptions()

Description copied from class: org.apache.log4j.AppenderSkeleton

Derived appenders should override this method if option structure requires it.

---

createConnection

protected abstract javax.jms.Connection createConnection()
                                                  throws javax.jms.JMSException,
                                                         javax.naming.NamingException

---

createSession

protected javax.jms.Session createSession()
                                   throws javax.jms.JMSException,
                                          javax.naming.NamingException

---

createProducer

protected javax.jms.MessageProducer createProducer()
                                            throws javax.jms.JMSException,
                                                   javax.naming.NamingException

---

append

protected void append(org.apache.log4j.spi.LoggingEvent event)

Description copied from class: org.apache.log4j.AppenderSkeleton

Subclasses of AppenderSkeleton should implement this method to perform actual logging. See also AppenderSkeleton.doAppend 55 method.

---

createMessage

protected javax.jms.Message createMessage(org.apache.log4j.spi.LoggingEvent event)
                                   throws javax.jms.JMSException,
                                          javax.naming.NamingException

---

getDestination

protected javax.jms.Destination getDestination(org.apache.log4j.spi.LoggingEvent event)
                                        throws javax.jms.JMSException,
