Method Detail

setConnectionFactory

public void setConnectionFactory(ConnectionFactory connectionFactory)

Set the connection factory used for obtaining JMS connections.

getConnectionFactory

public ConnectionFactory getConnectionFactory()

Return the connection factory used for obtaining JMS connections.

setSessionTransacted

public void setSessionTransacted(boolean sessionTransacted)

Set the transaction mode that is used when creating a JMS session to send a message. Default is "false".

Note that that within a JTA transaction, the parameters to create(Queue/Topic)Session(boolean transacted, int acknowledgeMode) method are not taken into account. Depending on the J2EE transaction context, the container makes its own decisions on these values. See section 17.3.5 of the EJB Spec.

Parameters:

sessionTransacted - the transaction mode

See Also:

Connection.createSession(boolean, int)

isSessionTransacted

public boolean isSessionTransacted()

Return whether the JMS sessions used for sending a message are transacted.

setSessionAcknowledgeModeName

public void setSessionAcknowledgeModeName(String constantName)

Set the JMS acknowledgement mode by the name of the corresponding constant in the JMS Session interface, e.g. "CLIENT_ACKNOWLEDGE".

Parameters:

constantName - name of the constant

See Also:

Session.AUTO_ACKNOWLEDGE, Session.CLIENT_ACKNOWLEDGE, Session.DUPS_OK_ACKNOWLEDGE, Connection.createSession(boolean, int)

setSessionAcknowledgeMode

public void setSessionAcknowledgeMode(int sessionAcknowledgeMode)

Set the JMS acknowledgement mode that is used when creating a JMS session to send a message. Vendor extensions to the acknowledgment mode can be set here as well. Default is "AUTO_ACKNOWLEDGE".

Note that that inside an EJB the parameters to create(Queue/Topic)Session(boolean transacted, int acknowledgeMode) method are not taken into account. Depending on the transaction context in the EJB, the container makes its own decisions on these values. See section 17.3.5 of the EJB Spec.

Parameters:

sessionAcknowledgeMode - the acknowledgement mode

See Also:

Session.AUTO_ACKNOWLEDGE, Session.CLIENT_ACKNOWLEDGE, Session.DUPS_OK_ACKNOWLEDGE, Connection.createSession(boolean, int)

getSessionAcknowledgeMode

public int getSessionAcknowledgeMode()

Return the acknowledgement mode for JMS sessions.

afterPropertiesSet

public void afterPropertiesSet()

Description copied from interface: InitializingBean

Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

Specified by:

afterPropertiesSet in interface InitializingBean

convertJmsAccessException

protected JmsException convertJmsAccessException(JMSException ex)

Convert the specified checked JMSException to a Spring runtime JmsException equivalent.

Default implementation delegates to JmsUtils.

Parameters:

ex - the original checked JMSException to convert

Returns:

the Spring runtime JmsException wrapping ex
