Method Detail

createNonXASession

public Session createNonXASession(boolean transacted,
                                  int acknowledgeMode)
                           throws JMSException

This internal method serves basically the Resource Adapter. The resource adapter plays with an XASession and a non XASession. When there is no enlisted transaction, the EE specification mandates that the commit should be done as if it was a nonXA Session (i.e. SessionTransacted). For that reason we have this method to force that nonXASession, since the JMS Javadoc mandates createSession to return a XASession.

Throws:

JMSException

createNonXATopicSession

public Session createNonXATopicSession(boolean transacted,
                                       int acknowledgeMode)

createSession

public Session createSession(boolean transacted,
                             int acknowledgeMode)
                      throws JMSException

Description copied from interface: Connection

Creates a Session object, specifying transacted and acknowledgeMode.

This method has been superseded by the method createSession(int sessionMode) which specifies the same information using a single argument, and by the method createSession() which is for use in a Java EE JTA transaction. Applications should consider using those methods instead of this one.

The effect of setting the transacted and acknowledgeMode arguments depends on whether this method is called in a Java SE environment, in the Java EE application client container, or in the Java EE web or EJB container. If this method is called in the Java EE web or EJB container then the effect of setting the transacted} and acknowledgeMode arguments also depends on whether or not there is an active JTA transaction in progress.

In a Java SE environment or in the Java EE application client container:

• If transacted is set to true then the session will use a local transaction which may subsequently be committed or rolled back by calling the session's commit or rollback methods. The argument acknowledgeMode is ignored.
• If transacted is set to false then the session will be non-transacted. In this case the argument acknowledgeMode is used to specify how messages received by this session will be acknowledged. The permitted values are Session.CLIENT_ACKNOWLEDGE, Session.AUTO_ACKNOWLEDGE and Session.DUPS_OK_ACKNOWLEDGE. For a definition of the meaning of these acknowledgement modes see the links below.

In a Java EE web or EJB container, when there is an active JTA transaction in progress:

• Both arguments transacted and acknowledgeMode are ignored. The session will participate in the JTA transaction and will be committed or rolled back when that transaction is committed or rolled back, not by calling the session's commit or rollback methods. Since both arguments are ignored, developers are recommended to use createSession(), which has no arguments, instead of this method.

In the Java EE web or EJB container, when there is no active JTA transaction in progress:

• The argument transacted is ignored. The session will always be non-transacted, using one of the two acknowledgement modes AUTO_ACKNOWLEDGE and DUPS_OK_ACKNOWLEDGE.
• The argument acknowledgeMode is used to specify how messages received by this session will be acknowledged. The only permitted values in this case are Session.AUTO_ACKNOWLEDGE and Session.DUPS_OK_ACKNOWLEDGE. The value Session.CLIENT_ACKNOWLEDGE may not be used. For a definition of the meaning of these acknowledgement modes see the links below.

Applications running in the Java EE web and EJB containers must not attempt to create more than one active (not closed) Session object per connection. If this method is called in a Java EE web or EJB container when an active Session object already exists for this connection then a JMSException will be thrown.

Specified by:

createSession in interface Connection

Parameters:

transacted - indicates whether the session will use a local transaction. If this method is called in the Java EE web or EJB container then this argument is ignored.

acknowledgeMode - indicates how messages received by the session will be acknowledged.

• If this method is called in a Java SE environment or in the Java EE application client container, the permitted values are Session.CLIENT_ACKNOWLEDGE, Session.AUTO_ACKNOWLEDGE and Session.DUPS_OK_ACKNOWLEDGE.
• If this method is called in the Java EE web or EJB container when there is an active JTA transaction in progress then this argument is ignored.
• If this method is called in the Java EE web or EJB container when there is no active JTA transaction in progress, the permitted values are Session.AUTO_ACKNOWLEDGE and Session.DUPS_OK_ACKNOWLEDGE. In this case Session.CLIENT_ACKNOWLEDGE is not permitted.

Returns:

a newly created session

Throws:

JMSException - if the Connection object fails to create a session due to

• some internal error,
• lack of support for the specific transaction and acknowledgement mode, or
• because this method is being called in a Java EE web or EJB application and an active session already exists for this connection.

getClientID

public String getClientID()
                   throws JMSException

Description copied from interface: Connection

Gets the client identifier for this connection.

This value is specific to the JMS provider. It is either preconfigured by an administrator in a ConnectionFactory object or assigned dynamically by the application by calling the setClientID method.

Specified by:

getClientID in interface Connection

Returns:

the unique client identifier

Throws:

JMSException - if the JMS provider fails to return the client ID for this connection due to some internal error.

setClientID

public void setClientID(String clientID)
                 throws JMSException

Description copied from interface: Connection

Sets the client identifier for this connection.

The preferred way to assign a JMS client's client identifier is for it to be configured in a client-specific ConnectionFactory object and transparently assigned to the Connection object it creates.

Alternatively, a client can set a connection's client identifier using a provider-specific value. The facility to set a connection's client identifier explicitly is not a mechanism for overriding the identifier that has been administratively configured. It is provided for the case where no administratively specified identifier exists. If one does exist, an attempt to change it by setting it must throw an IllegalStateException. If a client sets the client identifier explicitly, it must do so immediately after it creates the connection and before any other action on the connection is taken. After this point, setting the client identifier is a programming error that should throw an IllegalStateException.

The purpose of the client identifier is to associate a connection and its objects with a state maintained on behalf of the client by a provider. The only such state identified by the JMS API is that required to support durable subscriptions.

If another connection with the same clientID is already running when this method is called, the JMS provider should detect the duplicate ID and throw an InvalidClientIDException.

This method must not be used in a Java EE web or EJB application. Doing so may cause a JMSException to be thrown though this is not guaranteed.

Specified by:

setClientID in interface Connection

Parameters:

clientID - the unique client identifier

Throws:

JMSException - if the JMS provider fails to set the client ID for the the connection for one of the following reasons:

• an internal error has occurred or
• this method has been called in a Java EE web or EJB application (though it is not guaranteed that an exception is thrown in this case)

InvalidClientIDException - if the JMS client specifies an invalid or duplicate client ID.

IllegalStateException - if the JMS client attempts to set a connection's client ID at the wrong time or when it has been administratively configured.

getMetaData

public ConnectionMetaData getMetaData()
                               throws JMSException

Description copied from interface: Connection

Gets the metadata for this connection.

Specified by:

getMetaData in interface Connection

Returns:

the connection metadata

Throws:

JMSException - if the JMS provider fails to get the connection metadata for this connection.

See Also:

ConnectionMetaData

getExceptionListener

public ExceptionListener getExceptionListener()
                                       throws JMSException

Description copied from interface: Connection

Gets the ExceptionListener object for this connection. Not every Connection has an ExceptionListener associated with it.

Specified by:

getExceptionListener in interface Connection

Returns:

the ExceptionListener for this connection, or null. if no ExceptionListener is associated with this connection.

Throws:

JMSException - if the JMS provider fails to get the ExceptionListener for this connection.

See Also:

Connection.setExceptionListener(javax.jms.ExceptionListener)

setExceptionListener

public void setExceptionListener(ExceptionListener listener)
                          throws JMSException

Description copied from interface: Connection

Sets an exception listener for this connection.

If a JMS provider detects a serious problem with a connection, it informs the connection's ExceptionListener, if one has been registered. It does this by calling the listener's onException method, passing it a JMSException object describing the problem.

An exception listener allows a client to be notified of a problem asynchronously. Some connections only consume messages, so they would have no other way to learn their connection has failed.

A connection serializes execution of its ExceptionListener.

A JMS provider should attempt to resolve connection problems itself before it notifies the client of them.

This method must not be used in a Java EE web or EJB application. Doing so may cause a JMSException to be thrown though this is not guaranteed.

Specified by:

setExceptionListener in interface Connection

Parameters:

listener - the exception listener

Throws:

JMSException - if the JMS provider fails to set the exception listener for one of the following reasons:

• an internal error has occurred or
• this method has been called in a Java EE web or EJB application (though it is not guaranteed that an exception is thrown in this case)

start

public void start()
           throws JMSException

Description copied from interface: Connection

Starts (or restarts) a connection's delivery of incoming messages. A call to start on a connection that has already been started is ignored.

Specified by:

start in interface Connection

Throws:

JMSException - if the JMS provider fails to start message delivery due to some internal error.

See Also:

Connection.stop()

signalStopToAllSessions

public void signalStopToAllSessions()

stop

public void stop()
          throws JMSException

Description copied from interface: Connection

Temporarily stops a connection's delivery of incoming messages. Delivery can be restarted using the connection's start method. When the connection is stopped, delivery to all the connection's message consumers is inhibited: synchronous receives block, and messages are not delivered to message listeners.

This call blocks until receives and/or message listeners in progress have completed.

Stopping a connection has no effect on its ability to send messages. A call to stop on a connection that has already been stopped is ignored.

A call to stop must not return until delivery of messages has paused. This means that a client can rely on the fact that none of its message listeners will be called and that all threads of control waiting for receive calls to return will not return with a message until the connection is restarted. The receive timers for a stopped connection continue to advance, so receives may time out while the connection is stopped.

If message listeners are running when stop is invoked, the stop call must wait until all of them have returned before it may return. While these message listeners are completing, they must have the full services of the connection available to them.

A message listener must not attempt to stop its own connection as this would lead to deadlock. The JMS provider must detect this and throw a IllegalStateException.

For the avoidance of doubt, if an exception listener for this connection is running when stop is invoked, there is no requirement for the stop call to wait until the exception listener has returned before it may return.

This method must not be used in a Java EE web or EJB application. Doing so may cause a JMSException to be thrown though this is not guaranteed.

Specified by:

stop in interface Connection

Throws:

IllegalStateException - this method has been called by a MessageListener on its own Connection

JMSException - if the JMS provider fails to stop message delivery for one of the following reasons:

• an internal error has occurred or
• this method has been called in a Java EE web or EJB application (though it is not guaranteed that an exception is thrown in this case)

See Also:

Connection.start()

close

public final void close()
                 throws JMSException

Description copied from interface: Connection

Closes the connection.

Since a provider typically allocates significant resources outside the JVM on behalf of a connection, clients should close these resources when they are not needed. Relying on garbage collection to eventually reclaim these resources may not be timely enough.

There is no need to close the sessions, producers, and consumers of a closed connection.

Closing a connection causes all temporary destinations to be deleted.

When this method is invoked, it should not return until message processing has been shut down in an orderly fashion. This means that all message listeners that may have been running have returned, and that all pending receives have returned. A close terminates all pending message receives on the connection's sessions' consumers. The receives may return with a message or with null, depending on whether there was a message available at the time of the close. If one or more of the connection's sessions' message listeners is processing a message at the time when connection close is invoked, all the facilities of the connection and its sessions must remain available to those listeners until they return control to the JMS provider.

This method must not return until any incomplete asynchronous send operations for this Connection have been completed and any CompletionListener callbacks have returned. Incomplete sends should be allowed to complete normally unless an error occurs.

For the avoidance of doubt, if an exception listener for this connection is running when close is invoked, there is no requirement for the close call to wait until the exception listener has returned before it may return.

Closing a connection causes any of its sessions' transactions in progress to be rolled back. In the case where a session's work is coordinated by an external transaction manager, a session's commit and rollback methods are not used and the result of a closed session's work is determined later by the transaction manager. Closing a connection does NOT force an acknowledgment of client-acknowledged sessions.

A message listener must not attempt to close its own connection as this would lead to deadlock. The JMS provider must detect this and throw a IllegalStateException.

A CompletionListener callback method must not call close on its own Connection. Doing so will cause an IllegalStateException to be thrown.

Invoking the acknowledge method of a received message from a closed connection's session must throw an IllegalStateException. Closing a closed connection must NOT throw an exception.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Connection

Throws:

IllegalStateException -

• this method has been called by a MessageListener on its own Connection
• this method has been called by a CompletionListener callback method on its own Connection

JMSException - if the JMS provider fails to close the connection due to some internal error. For example, a failure to release resources or to close a socket connection can cause this exception to be thrown.

createSession

public Session createSession(int sessionMode)
                      throws JMSException

Description copied from interface: Connection

Creates a Session object, specifying sessionMode.

The effect of setting the sessionMode argument depends on whether this method is called in a Java SE environment, in the Java EE application client container, or in the Java EE web or EJB container. If this method is called in the Java EE web or EJB container then the effect of setting the sessionMode argument also depends on whether or not there is an active JTA transaction in progress.

In a Java SE environment or in the Java EE application client container:

• If sessionMode is set to Session.SESSION_TRANSACTED then the session will use a local transaction which may subsequently be committed or rolled back by calling the session's commit or rollback methods.
• If sessionMode is set to any of Session.CLIENT_ACKNOWLEDGE, Session.AUTO_ACKNOWLEDGE or Session.DUPS_OK_ACKNOWLEDGE. then the session will be non-transacted and messages received by this session will be acknowledged according to the value of sessionMode. For a definition of the meaning of these acknowledgement modes see the links below.

In a Java EE web or EJB container, when there is an active JTA transaction in progress:

• The argument sessionMode is ignored. The session will participate in the JTA transaction and will be committed or rolled back when that transaction is committed or rolled back, not by calling the session's commit or rollback methods. Since the argument is ignored, developers are recommended to use createSession(), which has no arguments, instead of this method.

In the Java EE web or EJB container, when there is no active JTA transaction in progress:

• The argument acknowledgeMode must be set to either of Session.AUTO_ACKNOWLEDGE or Session.DUPS_OK_ACKNOWLEDGE. The session will be non-transacted and messages received by this session will be acknowledged automatically according to the value of acknowledgeMode. For a definition of the meaning of these acknowledgement modes see the links below. The values Session.SESSION_TRANSACTED and Session.CLIENT_ACKNOWLEDGE may not be used.

Applications running in the Java EE web and EJB containers must not attempt to create more than one active (not closed) Session object per connection. If this method is called in a Java EE web or EJB container when an active Session object already exists for this connection then a JMSException will be thrown.

Specified by:

createSession in interface Connection

Parameters:

sessionMode - indicates which of four possible session modes will be used.

• If this method is called in a Java SE environment or in the Java EE application client container, the permitted values are Session.SESSION_TRANSACTED, Session.CLIENT_ACKNOWLEDGE, Session.AUTO_ACKNOWLEDGE and Session.DUPS_OK_ACKNOWLEDGE.
• If this method is called in the Java EE web or EJB container when there is an active JTA transaction in progress then this argument is ignored.
• If this method is called in the Java EE web or EJB container when there is no active JTA transaction in progress, the permitted values are Session.AUTO_ACKNOWLEDGE and Session.DUPS_OK_ACKNOWLEDGE. In this case the values Session.TRANSACTED and Session.CLIENT_ACKNOWLEDGE are not permitted.

Returns:

a newly created session

Throws:

JMSException - if the Connection object fails to create a session due to

• some internal error,
• lack of support for the specific transaction and acknowledgement mode, or
• because this method is being called in a Java EE web or EJB application and an active session already exists for this connection.

createSession

public Session createSession()
                      throws JMSException

Description copied from interface: Connection

Creates a Session object, specifying no arguments.

The behaviour of the session that is created depends on whether this method is called in a Java SE environment, in the Java EE application client container, or in the Java EE web or EJB container. If this method is called in the Java EE web or EJB container then the behaviour of the session also depends on whether or not there is an active JTA transaction in progress.

In a Java SE environment or in the Java EE application client container:

• The session will be non-transacted and received messages will be acknowledged automatically using an acknowledgement mode of Session.AUTO_ACKNOWLEDGE For a definition of the meaning of this acknowledgement mode see the link below.

In a Java EE web or EJB container, when there is an active JTA transaction in progress:

• The session will participate in the JTA transaction and will be committed or rolled back when that transaction is committed or rolled back, not by calling the session's commit or rollback methods.

In the Java EE web or EJB container, when there is no active JTA transaction in progress:

• The session will be non-transacted and received messages will be acknowledged automatically using an acknowledgement mode of Session.AUTO_ACKNOWLEDGE For a definition of the meaning of this acknowledgement mode see the link below.

Applications running in the Java EE web and EJB containers must not attempt to create more than one active (not closed) Session object per connection. If this method is called in a Java EE web or EJB container when an active Session object already exists for this connection then a JMSException will be thrown.

Specified by:

createSession in interface Connection

Returns:

a newly created session

Throws:

JMSException - if the Connection object fails to create a session due to

• some internal error or
• because this method is being called in a Java EE web or EJB application and an active session already exists for this connection.

createQueueSession

public QueueSession createQueueSession(boolean transacted,
                                       int acknowledgeMode)
                                throws JMSException

Description copied from interface: QueueConnection

Creates a QueueSession object.

Specified by:

createQueueSession in interface QueueConnection

Parameters:

transacted - indicates whether the session is transacted

acknowledgeMode - indicates whether the consumer or the client will acknowledge any messages it receives; ignored if the session is transacted. Legal values are Session.AUTO_ACKNOWLEDGE, Session.CLIENT_ACKNOWLEDGE, and Session.DUPS_OK_ACKNOWLEDGE.

Returns:

a newly created queue session

Throws:

JMSException - if the QueueConnection object fails to create a session due to some internal error or lack of support for the specific transaction and acknowledgement mode.

Session.AUTO_ACKNOWLEDGE, Session.CLIENT_ACKNOWLEDGE, Session.DUPS_OK_ACKNOWLEDGE

checkAck

public static int checkAck(boolean transacted,
                           int acknowledgeMode)

I'm keeping this as static as the same check will be done within RA. This is to conform with TCK Tests where we must return ackMode exactly as they want if transacted=false
