Interface JMSProducer

public interface JMSProducer
A JMSProducer is a simple object used to send messages on behalf of a JMSContext. An instance of JMSProducer is created by calling the createProducer method on a JMSContext. It provides various send methods to send a message to a specified destination. It also provides methods to allow message send options, message properties and message headers to be specified prior to sending a message or set of messages.

Message send options may be specified using one or more of the following methods: setDeliveryMode, setPriority, setTimeToLive, setDeliveryDelay, setDisableMessageTimestamp, setDisableMessageID and setAsync.

Message properties may be may be specified using one or more of nine setProperty methods. Any message properties set using these methods will override any message properties that have been set directly on the message.

Message headers may be specified using one or more of the following methods: setJMSCorrelationID, setJMSCorrelationIDAsBytes, setJMSType or setJMSReplyTo. Any message headers set using these methods will override any message headers that have been set directly on the message.

All the above methods return the JMSProducer to allow method calls to be chained together, allowing a fluid programming style. For example:

context.createProducer().setDeliveryMode(DeliveryMode.NON_PERSISTENT).setTimeToLive(1000).send(destination, message);

Instances of JMSProducer are intended to be lightweight objects which can be created freely and which do not consume significant resources. This interface therefore does not provide a close method.

    • setDisableMessageID

      JMSProducer setDisableMessageID(boolean value)
      Specifies whether message IDs may be disabled for messages that are sent using this JMSProducer

      Since message IDs take some effort to create and increase a message's size, some Jakarta Messaging providers may be able to optimise message overhead if they are given a hint that the message ID is not used by an application. By calling this method, a Jakarta Messaging application enables this potential optimisation for all messages sent using this JMSProducer. If the Jakarta Messaging provider accepts this hint, these messages must have the message ID set to null; if the provider ignores the hint, the message ID must be set to its normal unique value.

      Message IDs are enabled by default.

      Parameters:
      value - indicates whether message IDs may be disabled
      Returns:
      this JMSProducer
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to set message ID to disabled due to some internal error.
      See Also:

    • getDisableMessageID

      boolean getDisableMessageID()
      Gets an indication of whether message IDs are disabled.
      Returns:
      an indication of whether message IDs are disabled
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to determine if message IDs are disabled due to some internal error.
      See Also:

    • setDisableMessageTimestamp

      JMSProducer setDisableMessageTimestamp(boolean value)
      Specifies whether message timestamps may be disabled for messages that are sent using this JMSProducer.

      Since timestamps take some effort to create and increase a message's size, some Jakarta Messaging providers may be able to optimise message overhead if they are given a hint that the timestamp is not used by an application. By calling this method, a Jakarta Messaging application enables this potential optimisation for all messages sent using this JMSProducer. If the JMS provider accepts this hint, these messages must have the timestamp set to zero; if the provider ignores the hint, the timestamp must be set to its normal value.

      Message timestamps are enabled by default.

      Parameters:
      value - indicates whether message timestamps may be disabled
      Returns:
      this JMSProducer
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to set timestamps to disabled due to some internal error.
      See Also:

    • getDisableMessageTimestamp

      boolean getDisableMessageTimestamp()
      Gets an indication of whether message timestamps are disabled.
      Returns:
      an indication of whether message timestamps are disabled
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to determine if timestamps are disabled due to some internal error.
      See Also:

    • setDeliveryMode

      JMSProducer setDeliveryMode(int deliveryMode)
      Specifies the delivery mode of messages that are sent using this JMSProducer

      Delivery mode is set to PERSISTENT by default.

      Parameters:
      deliveryMode - the message delivery mode to be used; legal values are DeliveryMode.NON_PERSISTENT and DeliveryMode.PERSISTENT
      Returns:
      this JMSProducer
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to set the delivery mode due to some internal error.
      See Also:

    • getDeliveryMode

      int getDeliveryMode()
      Returns the delivery mode of messages that are sent using this JMSProducer
      Returns:
      the message delivery mode
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to get the delivery mode due to some internal error.
      See Also:

    • setPriority

      JMSProducer setPriority(int priority)
      Specifies the priority of messages that are sent using this JMSProducer

      The Jakarta Messaging API defines ten levels of priority value, with 0 as the lowest priority and 9 as the highest. Clients should consider priorities 0-4 as gradations of normal priority and priorities 5-9 as gradations of expedited priority. Priority is set to 4 by default.

      Parameters:
      priority - the message priority to be used; must be a value between 0 and 9
      Returns:
      this JMSProducer
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to set the priority due to some internal error.
      See Also:

    • getPriority

      int getPriority()
      Return the priority of messages that are sent using this JMSProducer
      Returns:
      the message priority
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to get the priority due to some internal error.
      See Also:

    • setTimeToLive

      JMSProducer setTimeToLive(long timeToLive)
      Specifies the time to live of messages that are sent using this JMSProducer. This is used to determine the expiration time of a message.

      The expiration time of a message is the sum of the message's time to live and the time it is sent. For transacted sends, this is the time the client sends the message, not the time the transaction is committed.

      Clients should not receive messages that have expired; however, Jakarta Messaging does not guarantee that this will not happen.

      A Jakarta Messaging provider should do its best to accurately expire messages; however, Jakarta Messaging does not define the accuracy provided. It is not acceptable to simply ignore time-to-live.

      Time to live is set to zero by default, which means a message never expires.

      Parameters:
      timeToLive - the message time to live to be used, in milliseconds; a value of zero means that a message never expires.
      Returns:
      this JMSProducer
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to set the time to live due to some internal error.
      See Also:

    • getTimeToLive

      long getTimeToLive()
      Returns the time to live of messages that are sent using this JMSProducer.
      Returns:
      the message time to live in milliseconds; a value of zero means that a message never expires.
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to get the time to live due to some internal error.
      See Also:

    • setDeliveryDelay

      JMSProducer setDeliveryDelay(long deliveryDelay)
      Sets the minimum length of time in milliseconds that must elapse after a message is sent before the Jakarta Messaging provider may deliver the message to a consumer.

      For transacted sends, this time starts when the client sends the message, not when the transaction is committed.

      deliveryDelay is set to zero by default.

      Parameters:
      deliveryDelay - the delivery delay in milliseconds.
      Returns:
      this JMSProducer
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to set the delivery delay due to some internal error.
      See Also:

    • getDeliveryDelay

      long getDeliveryDelay()
      Gets the minimum length of time in milliseconds that must elapse after a message is sent before the Jakarta Messaging provider may deliver the message to a consumer.
      Returns:
      the delivery delay in milliseconds.
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to get the delivery delay due to some internal error.
      See Also:

    • setAsync

      JMSProducer setAsync(CompletionListener completionListener)
      Specifies whether subsequent calls to send on this JMSProducer object should be synchronous or asynchronous. If the specified CompletionListener is not null then subsequent calls to send will be asynchronous. If the specified CompletionListener is null then subsequent calls to send will be synchronous. Calls to send are synchronous by default.

      If a call to send is asynchronous then part of the work involved in sending the message will be performed in a separate thread and the specified CompletionListener will be notified when the operation has completed.

      When the message has been successfully sent the Jakarta Messaging provider invokes the callback method onCompletion on the CompletionListener object. Only when that callback has been invoked can the application be sure that the message has been successfully sent with the same degree of confidence as if the send had been synchronous. An application which requires this degree of confidence must therefore wait for the callback to be invoked before continuing.

      The following information is intended to give an indication of how an asynchronous send would typically be implemented.

      In some Jakarta Messaging providers, a normal synchronous send involves sending the message to a remote Jakarta Messaging server and then waiting for an acknowledgement to be received before returning. It is expected that such a provider would implement an asynchronous send by sending the message to the remote Jakarta Messaging server and then returning without waiting for an acknowledgement. When the acknowledgement is received, the Jakarta Messaging provider would notify the application by invoking the onCompletion method on the application-specified CompletionListener object. If for some reason the acknowledgement is not received the Jakarta Messaging provider would notify the application by invoking the CompletionListener's onException method.

      In those cases where the Jakarta Messaging specification permits a lower level of reliability, a normal synchronous send might not wait for an acknowledgement. In that case it is expected that an asynchronous send would be similar to a synchronous send: the Jakarta Messaging provider would send the message to the remote Jakarta Messaging server and then return without waiting for an acknowledgement. However the Jakarta Messaging provider would still notify the application that the send had completed by invoking the onCompletion method on the application-specified CompletionListener object.

      It is up to the Jakarta Messaging provider to decide exactly what is performed in the calling thread and what, if anything, is performed asynchronously, so long as it satisfies the requirements given below:

      Quality of service: After the send operation has completed successfully, which means that the message has been successfully sent with the same degree of confidence as if a normal synchronous send had been performed, the JMS provider must invoke the CompletionListener's onCompletion method. The CompletionListener must not be invoked earlier than this.

      Exceptions: If an exception is encountered during the call to the send method then an appropriate exception should be thrown in the thread that is calling the send method. In this case the Jakarta Messaging provider must not invoke the CompletionListener's onCompletion or onException method. If an exception is encountered which cannot be thrown in the thread that is calling the send method then the Jakarta Messaging provider must call the CompletionListener's onException method. In both cases if an exception occurs it is undefined whether or not the message was successfully sent.

      Message order: If the same JMSContext is used to send multiple messages then Jakarta Messaging message ordering requirements must be satisfied. This applies even if a combination of synchronous and asynchronous sends has been performed. The application is not required to wait for an asynchronous send to complete before sending the next message.

      Close, commit or rollback: If the close method is called on the JMSContext then the JMS provider must block until any incomplete send operations have been completed and all CompletionListener callbacks have returned before closing the object and returning. If the session is transacted (uses a local transaction) then when the JMSContext's commit or rollback method is called the JMS provider must block until any incomplete send operations have been completed and all CompletionListener callbacks have returned before performing the commit or rollback. Incomplete sends should be allowed to complete normally unless an error occurs.

      A CompletionListener callback method must not call close, commit or rollback on its own JMSContext. Doing so will cause the close, commit or rollback to throw an IllegalStateRuntimeException.

      Restrictions on usage in Jakarta EE This method must not be used in a Jakarta EE EJB or web container. Doing so may cause a JMSRuntimeException to be thrown though this is not guaranteed.

      Message headers Jakarta Messaging defines a number of message header fields and message properties which must be set by the "Jakarta Messaging provider on send". If the send is asynchronous these fields and properties may be accessed on the sending client only after the CompletionListener has been invoked. If the CompletionListener's onException method is called then the state of these message header fields and properties is undefined.

      Restrictions on threading: Applications that perform an asynchronous send must confirm to the threading restrictions defined in JMS. This means that the session may be used by only one thread at a time.

      Setting a CompletionListener does not cause the session to be dedicated to the thread of control which calls the CompletionListener. The application thread may therefore continue to use the session after performing an asynchronous send. However the CompletionListener's callback methods must not use the session if an application thread might be using the session at the same time.

      Use of the CompletionListener by the Jakarta Messaging provider: A session will only invoke one CompletionListener callback method at a time. For a given JMSContext, callbacks (both onCompletion and onException) will be performed in the same order as the corresponding calls to the send method. A Jakarta Messaging provider must not invoke the CompletionListener from the thread that is calling the send method.

      Restrictions on the use of the Message object: Applications which perform an asynchronous send must take account of the restriction that a Message object is designed to be accessed by one logical thread of control at a time and does not support concurrent use.

      After the send method has returned, the application must not attempt to read the headers, properties or body of the Message object until the CompletionListener's onCompletion or onException method has been called. This is because the Jakarta Messaging provider may be modifying the Message object in another thread during this time. The Jakarta Messaging provider may throw an JMSException if the application attempts to access or modify the Message object after the send method has returned and before the CompletionListener has been invoked. If the Jakarta Messaging provider does not throw an exception then the behaviour is undefined.

      Parameters:
      completionListener - If asynchronous send behaviour is required, this should be set to a CompletionListener to be notified when the send has completed. If synchronous send behaviour is required, this should be set to null.
      Returns:

    • getPropertyNames

      Set<String> getPropertyNames()
      Returns an unmodifiable Set view of the names of all the message properties that have been set on this JMSProducer.

      Note that Jakarta Messaging standard header fields are not considered properties and are not returned in this Set.

      The set is backed by the JMSProducer, so changes to the map are reflected in the set. However the set may not be modified. Attempts to modify the returned collection, whether directly or via its iterator, will result in an java.lang.UnsupportedOperationException. Its behaviour matches that defined in the java.util.Collections method unmodifiableSet.

      Returns:

      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to get the property names due to some internal error.
      See Also:

    • setJMSCorrelationIDAsBytes

      JMSProducer setJMSCorrelationIDAsBytes(byte[] correlationID)
      Specifies that messages sent using this JMSProducer will have their JMSCorrelationID header value set to the specified correlation ID, where correlation ID is specified as an array of bytes.

      This will override any JMSCorrelationID header value that is already set on the message being sent.

      The array is copied before the method returns, so future modifications to the array will not alter the value in this JMSProducer.

      If a provider supports the native concept of correlation ID, a Jakarta Messaging client may need to assign specific JMSCorrelationID values to match those expected by native messaging clients. Jakarta Messaging providers without native correlation ID values are not required to support this method and its corresponding get method; their implementation may throw a java.lang.UnsupportedOperationException.

      The use of a byte[] value for JMSCorrelationID is non-portable.

      Parameters:
      correlationID - the correlation ID value as an array of bytes
      Returns:
      this JMSProducer
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to set the correlation ID due to some internal error.
      See Also:

    • getJMSCorrelationIDAsBytes

      byte[] getJMSCorrelationIDAsBytes()
      Returns the JMSCorrelationID header value that has been set on this JMSProducer, as an array of bytes.

      The use of a byte[] value for JMSCorrelationID is non-portable.

      Returns:
      the correlation ID as an array of bytes
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to get the correlation ID due to some internal error.
      See Also:

    • setJMSCorrelationID

      JMSProducer setJMSCorrelationID(String correlationID)
      Specifies that messages sent using this JMSProducer will have their JMSCorrelationID header value set to the specified correlation ID, where correlation ID is specified as a String.

      This will override any JMSCorrelationID header value that is already set on the message being sent.

      A client can use the JMSCorrelationID header field to link one message with another. A typical use is to link a response message with its request message.

      JMSCorrelationID can hold one of the following:

      • A provider-specific message ID
      • An application-specific String
      • A provider-native byte[] value

      Since each message sent by a Jakarta Messaging provider is assigned a message ID value, it is convenient to link messages via message ID. All message ID values must start with the 'ID:' prefix.

      In some cases, an application (made up of several clients) needs to use an application-specific value for linking messages. For instance, an application may use JMSCorrelationID to hold a value referencing some external information. Application-specified values must not start with the 'ID:' prefix; this is reserved for provider-generated message ID values.

      If a provider supports the native concept of correlation ID, a Jakarta Messaging client may need to assign specific JMSCorrelationID values to match those expected by clients that do not use the Jakarta Messaging API. A byte[] value is used for this purpose. Jakarta Messaging providers without native correlation ID values are not required to support byte[] values. The use of a byte[] value for JMSCorrelationID is non-portable.

      Parameters:
      correlationID - the message ID of a message being referred to
      Returns:
      this JMSProducer
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to set the correlation ID due to some internal error.
      See Also:

    • getJMSCorrelationID

      String getJMSCorrelationID()
      Returns the JMSCorrelationID header value that has been set on this JMSProducer, as a String.

      This method is used to return correlation ID values that are either provider-specific message IDs or application-specific String values.

      Returns:
      the correlation ID of a message as a String
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to get the correlation ID due to some internal error.
      See Also:

    • setJMSType

      JMSProducer setJMSType(String type)
      Specifies that messages sent using this JMSProducer will have their JMSType header value set to the specified message type.

      This will override any JMSType header value that is already set on the message being sent.

      Some Jakarta Messaging providers use a message repository that contains the definitions of messages sent by applications. The JMSType header field may reference a message's definition in the provider's repository.

      The Jakarta Messaging API does not define a standard message definition repository, nor does it define a naming policy for the definitions it contains.

      Some messaging systems require that a message type definition for each application message be created and that each message specify its type. In order to work with such Jakarta Messaging providers, Jakarta Messaging clients should assign a value to JMSType, whether the application makes use of it or not. This ensures that the field is properly set for those providers that require it.

      To ensure portability, Jakarta Messaging clients should use symbolic values for JMSType that can be configured at installation time to the values defined in the current provider's message repository. If string literals are used, they may not be valid type names for some Jakarta Messaging providers.

      Parameters:
      type - the message type
      Returns:
      this JMSProducer
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to set the message type due to some internal error.
      See Also:

    • getJMSType

      String getJMSType()
      Returns the JMSType header value that has been set on this JMSProducer.
      Returns:
      the message type
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to get the message type due to some internal error.
      See Also:

    • setJMSReplyTo

      JMSProducer setJMSReplyTo(Destination replyTo)
      Specifies that messages sent using this JMSProducer will have their JMSReplyTo header value set to the specified Destination object.

      This will override any JMSReplyTo header value that is already set on the message being sent.

      The JMSReplyTo header field contains the destination where a reply to the current message should be sent. If it is null, no reply is expected. The destination may be either a Queue object or a Topic object.

      Messages sent with a null JMSReplyTo value may be a notification of some event, or they may just be some data the sender thinks is of interest.

      Messages with a JMSReplyTo value typically expect a response. A response is optional; it is up to the client to decide. These messages are called requests. A message sent in response to a request is called a reply.

      In some cases a client may wish to match a request it sent earlier with a reply it has just received. The client can use the JMSCorrelationID header field for this purpose.

      Parameters:
      replyTo - Destination to which to send a response to this message
      Returns:
      this JMSProducer
      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to set the JMSReplyTo destination due to some internal error.
      See Also:

    • getJMSReplyTo

      Destination getJMSReplyTo()
      Returns the JMSReplyTo header value that has been set on this JMSProducer.
      Returns:

      Throws:
      JMSRuntimeException - if the Jakarta Messaging provider fails to get the JMSReplyTo destination due to some internal error.
