public class JMSMessage extends Object implements jakarta.jms.Message, Serializable, JmsMessage

The Message interface is the root interface of all JMS messages. It defines the JMS header and the acknowledge() method used for all messages. The header contains fields used for message routing and identification. The payload contains the application data being sent.

JMS Messages are composed of the following parts:

  • Header: All messages support the same set of header fields. Header fields contain values used by both clients and providers to identify and route messages.
  • Properties: Each message contains a built-in facility for supporting application-defined property values. Properties provide an efficient mechanism for supporting application defined message filtering.
  • Body: JMS defines several types of message body which cover the majority of messaging styles currently in use.

JMS defines five types of message body:

  • Stream: a stream of Java primitive values. It is filled and read sequentially.
  • Map: a set of name-value pairs where names are Strings and values are Java primitive types. The entries can be accessed sequentially or randomly by name. The order of the entries is undefined.
  • Text: a message containing a java.util.StringBuffer. The inclusion of this message type allows XML to represent content of all kinds, including the content of JMS messages.
  • Object: a message that contains a Serializable java object
  • Bytes: a stream of uninterpreted bytes. This message type is for literally encoding a body to match an existing message format. In many cases, it will be possible to use one of the other, easier to use, body types instead. Although JMS allows the use of message properties with byte messages, it is typically not done since the inclusion of properties might affect the format.

The JMSCorrelationID header field is used to link one message with another. It typically links a reply message with its requesting message. A JMSCorrelationID can hold either a provider-specific message ID, an application-specific String, or a provider-specific byte[] value.

A Message contains a built-in facility for supporting application-defined property values. In effect, this provides a mechanism for adding application-specific header fields to a message. Properties allow an application, via message selectors, to have a JMS provider select and filter messages on its behalf using application-specific criteria. Property names must obey the rules for the selector identifier of a message. Property values can be boolean, byte, short, int, long, float, double, and String.

Property values are set prior to sending a message. When a client receives a message, its properties are in read-only mode. If a client attempts to set properties at this point, a MessageNotWriteableException is thrown. If clearProperties() is called, the properties can then be both read from and written to.

A property value might duplicate a value in a message's body or it might not. Although JMS does not define a policy for what might be made a property, JMS handles data in a message's body more efficiently than data in a message's properties. For best performance, applications should only use message properties when they need to customize a message's header. The primary reason for doing this is to support customized message selection.

Message properties support the following conversion table. The marked cases are supported. The unmarked cases throw a JMSException. The String to primitive conversions might throw a runtime exception if the primitives valueOf() method does not accept it as a valid String representation of the primitive.

A value written as the row type can be read as the column type.

boolean byte short char int long float double String
boolean X X
byte X X X X X
short X X X X
char X X
int X X X
long X X
float X X X
double X X
String X X X X X X X X

In addition to the type-specific set and get methods for properties, JMS provides the setObjectProperty() and getObjectProperty() methods. These support the same set of property types using the 'objectified' primitive values. Their purpose is to allow the property type to be decided at execution time rather than at compile time. They support the same property value conversions.

The setObjectProperty() method accepts values of class Boolean, Byte, Short, Integer, Long, Float, Double and String. An attempt to use any other class throws a JMSException. The getObjectProperty() method only returns values of class Boolean, Byte, Short, Integer, Long, Float, Double and String.

The order of property values is not defined. To iterate through a message's property values, use getPropertyNames() to retrieve a property name Enumeration and then use the various property accessor methods to retrieve their values.

A message's properties are deleted by the clearProperties() method. This leaves the message with an empty set of properties.

Getting a property value for a name which has not been set returns a null value. Only the getStringProperty() and getObjectProperty() methods can return a null value. The other property get methods throw a java.lang.NullPointerException if they are used to get a nonexistent property.

JMS reserves the “JMSX” property name prefix for JMS defined properties. The full set of these properties is defined in the Java Message Service specification. The String[] ConnectionMetaData.getJMSXPropertyNames() method returns the names of the JMSX properties supported by a connection. JMSX properties can be referenced in message selectors whether or not they are supported by a connection. They are treated like any other absent property.

JSMX properties “set by provider on send” are available to both the producer and the consumers of the message. JSMX properties “set by provider on receive” are only available to the consumers.

JMSXGroupID and JMSXGroupSeq are simply standard properties that clients can use if they want to group messages.

JMS reserves the “JMS_ <vendor_name>” property name prefix.

If an application tries to set a message property with a name that commences JMS, but the name is not one of the names in the following list, IBM MQ JMS throws an exception:

  • JMSXGroupID
  • JJMSXGroupSeq
  • JMS_IBM_Format
  • JMS_IBM_MsgType
  • JMS_IBM_Feedback
  • JMS_IBM_PutApplType
  • JMS_IBM_Report_Exception
  • JMS_IBM_Report_Expiration
  • JMS_IBM_Report_COA
  • JMS_IBM_Report_COD
  • JMS_IBM_Report_PAN
  • JMS_IBM_Report_NAN
  • JMS_IBM_Report_Pass_Msg_ID
  • JMS_IBM_Report_Pass_Correl_ID
  • JMS_IBM_Report_Discard_Msg

    • getJMSDestination

      public jakarta.jms.Destination getJMSDestination() throws jakarta.jms.JMSException
      Gets the destination for this message.

      The destination field contains the destination to which the message is being sent.

      When a message is sent, this value is ignored. After completion of the send() method it holds the destination specified by the send().

      When a message is received, its destination value must be equivalent to the value assigned when it was sent.

      Specified by:
      getJMSDestination in interface jakarta.jms.Message
      Returns:
      the destination of this message
      Throws:
      jakarta.jms.JMSException - if the destination is invalid
    • getJMSExpiration

      public long getJMSExpiration() throws jakarta.jms.JMSException
      Gets the message's expiration value.

      When a message is sent, expiration is left unassigned. After completion of the send method, it holds the expiration time of the message. This is the time-to-live value specified by the client added to the time (GMT) when the message was sent.

      If the time-to-live is specified as zero, expiration is set to zero which indicates the message does not expire.

      When a message's expiration time is reached, a provider should discard it. JMS does not define any form of notification of message expiration.

      Clients might receive messages that have expired: JMS does not guarantee that this will not happen.

      Specified by:
      getJMSExpiration in interface jakarta.jms.Message
      Returns:
      the time (GMT) when the message expires
      Throws:
      jakarta.jms.JMSException - if an internal error occurs
    • getJMSMessageID

      public String getJMSMessageID() throws jakarta.jms.JMSException
      Gets the message ID.

      The messageID header field contains a value that uniquely identifies each message sent by a provider.

      When a message is sent, messageID can be ignored. When the send() method returns, it contains a provider-assigned value.

      A JMSMessageID is a String value which functions as a unique key for identifying messages in a historical repository. The exact scope of uniqueness is provider defined. It should at least cover all messages for a specific installation of a provider where an installation is some connected set of message routers.

      All JMSMessageID values must start with the prefix “ID:”. Uniqueness of message ID values across different providers is not required.

      Specified by:
      getJMSMessageID in interface jakarta.jms.Message
      Returns:
      the message ID
      Throws:
      jakarta.jms.JMSException - if an internal error occurs
    • getJMSPriority

      public int getJMSPriority() throws jakarta.jms.JMSException
      Gets the message priority.

      JMS defines ten levels of priority with 0 as the lowest and 9 as the highest. In addition, clients should consider priorities 0-4 as gradations of normal priority and priorities 5-9 as gradations of expedited priority.

      Specified by:
      getJMSPriority in interface jakarta.jms.Message
      Returns:
      the default message priority
      Throws:
      jakarta.jms.JMSException - if an internal error occurs
    • getJMSRedelivered

      public boolean getJMSRedelivered() throws jakarta.jms.JMSException
      Gets an indication of whether this message is being redelivered.

      If a client receives a message with the redelivered indicator set, it is likely, but not guaranteed, that this message was delivered to the client earlier but the client did not acknowledge its receipt at that earlier time.

      Specified by:
      getJMSRedelivered in interface jakarta.jms.Message
      Returns:
      set to true if this message is being redelivered, false otherwise
      Throws:
      jakarta.jms.JMSException - if an internal error occurs
    • getJMSReplyTo

      public jakarta.jms.Destination getJMSReplyTo() throws jakarta.jms.JMSException
      Gets the destination to which a reply to this message should be sent.
      Specified by:
      getJMSReplyTo in interface jakarta.jms.Message
      Returns:
      where to send a response to this message
      Throws:
      jakarta.jms.JMSException - if the destination is invalid
    • getJMSTimestamp

      public long getJMSTimestamp() throws jakarta.jms.JMSException
      Gets the message timestamp.

      The JMSTimestamp header field contains the time a message was handed to a provider to be sent. It is not the time the message was actually transmitted because that might occur later due to transactions or other client-side queueing of messages.

      When a message is sent, JMSTimestamp is ignored. When the send method returns, it contains a time somewhere between the call and the return. It is in the format of a normal Java millisecond time value.

      Specified by:
      getJMSTimestamp in interface jakarta.jms.Message
      Returns:
      the message timestamp
      Throws:
      jakarta.jms.JMSException - if an internal error occurs
    • getJMSType

      public String getJMSType() throws jakarta.jms.JMSException
      Gets the message type.
      Specified by:
      getJMSType in interface jakarta.jms.Message

      Parameters:
      name - the name of the long property
      Returns:
      the long property value with the given name
      Throws:
      jakarta.jms.MessageFormatException - if this type conversion is not valid
      jakarta.jms.JMSException - if the property name is null or if the operation fails for an internal reason
    • getObjectProperty

      public Object getObjectProperty(String name) throws jakarta.jms.JMSException
      Gets the Java object property value with the given name.

      This method can be used to return, in objectified format, an object that had been stored as a property in the Message with the equivalent setObject() method call, or its equivalent primitive setter method.

      Specified by:
      getObjectProperty in interface jakarta.jms.Message
      Parameters:
      name - the name of the Java object property.
      Returns:
      the Java object property value with the given name in objectified format (that is, if it set as an int, then an Integer is returned). If there is no property with this name, a null value is returned.
      Throws:
      jakarta.jms.JMSException - if the property name is null or if the operation fails for an internal reason

    • setJMSCorrelationID

      public void setJMSCorrelationID(String correlationID) throws jakarta.jms.JMSException
      Sets the correlation ID for the message.

      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 JMS provider is assigned a message ID, it is convenient to link messages using their message IDs. 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 example, an application might 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 JMS client might need to assign specific JMSCorrelationID values to match those expected by non-JMS clients. A byte[] value is used for this purpose. The use of a byte[] value for JMSCorrelationID is not portable.

      Specified by:
      setJMSCorrelationID in interface jakarta.jms.Message
      Parameters:
      correlationID - the message ID of a message being referred to
      Throws:
      jakarta.jms.JMSException - if the correlation id is invalid
    • setJMSCorrelationIDAsBytes

      public void setJMSCorrelationIDAsBytes(byte[] correlID) throws jakarta.jms.JMSException
      Sets the correlation ID as an array of bytes for the message.

      If a provider supports the native concept of correlation id, a JMS client might need to assign specific JMSCorrelationID values to match those expected by non-JMS clients.

      A client can use this call to set the correlationID either to a messageID from a previous message, or to an application-specific string. Application-specific strings must not start with the characters 'ID:'.

      The use of a byte[] value for JMSCorrelationID is not portable.

      Specified by:
      setJMSCorrelationIDAsBytes in interface jakarta.jms.Message
      Parameters:
      correlID - the correlation ID value as an array of bytes
      Throws:
      jakarta.jms.JMSException - if an internal error occurs
      IndexOutOfBoundsException - if copying would cause access to data outside array bounds
      ArrayStoreException - if an element in the source array could not be stored into the destination array because of a type mismatch
      NullPointerException - if either source or destination is null
    • setJMSDeliveryMode

      public void setJMSDeliveryMode(int deliveryMode) throws jakarta.jms.JMSException
      Sets the delivery mode for this message.

      Any value set using this method is ignored when the message is sent, but this method can be used to change the value in a received message.

      To alter the delivery mode when a message is sent, use the setDeliveryMode() method on the QueueSender or TopicPublisher (this method is inherited from MessageProducer).

      Specified by:
      setJMSDeliveryMode in interface jakarta.jms.Message
      Parameters:
      deliveryMode - the delivery mode for this message
      Throws:
      jakarta.jms.JMSException - if an internal error occurs
      See Also:
    • setJMSDestination

      public void setJMSDestination(jakarta.jms.Destination destination) throws jakarta.jms.JMSException
      Sets the destination for this message.

      Any value set using this method is ignored when the message is sent, but this method can be used to change the value in a received message.

      Specified by:
      setJMSDestination in interface jakarta.jms.Message
      Parameters:
      destination - the destination for this message
      Throws:
      jakarta.jms.JMSException - if an internal error occurs
    • setJMSExpiration

      public void setJMSExpiration(long expiration) throws jakarta.jms.JMSException
      Sets the message's expiration value.

      Any value set using this method is ignored when the message is sent, but this method can be used to change the value in a received message.

      Specified by:
      setJMSExpiration in interface jakarta.jms.Message
      Parameters:
      expiration - the message's expiration time
      Throws:
      jakarta.jms.JMSException - if an internal error occurs

    • setJMSMessageID

      public void setJMSMessageID(String id) throws jakarta.jms.JMSException
      Sets the message ID.

      Any value set using this method is ignored when the message is sent, but this method can be used to change the value in a received message.

      Because a message ID set by this method is ignored when a message is sent, an application cannot specify the message ID of an outgoing message. As a consequence, an application cannot receive a message and then forward the same message, or send a different message, with the same message ID as that of the message it has received.

      Specified by:
      setJMSMessageID in interface jakarta.jms.Message
      Parameters:
      id - the ID of the message.
      Throws:
      jakarta.jms.JMSException - if an internal error occurs.

    • setJMSPriority

      public void setJMSPriority(int priority) throws jakarta.jms.JMSException
      Sets the priority for this message.

      Providers set this field when a message is sent. This operation can be used to change the value of a message that has been received.

      JMS defines a ten levels of priority with 0 as the lowest and 9 as the highest. In addition, clients must consider priorities 0-4 as gradations of normal priority, and priorities 5-9 as gradations of expedited priority.

      Specified by:
      setJMSPriority in interface jakarta.jms.Message
      Parameters:
      priority - the priority of this message
      Throws:
      jakarta.jms.JMSException - if an internal error occurs
    • setJMSRedelivered

      public void setJMSRedelivered(boolean redelivered) throws jakarta.jms.JMSException
      Sets a boolean to indicate whether this message is being redelivered.

      This field is set at the time the message is delivered. This operation can be used to change the value of a message that has been received.

      Specified by:
      setJMSRedelivered in interface jakarta.jms.Message
      Parameters:
      redelivered - an indication of whether this message is being re-delivered
      Throws:
      jakarta.jms.JMSException - if an internal error occurs
    • setJMSReplyTo

      public void setJMSReplyTo(jakarta.jms.Destination replyTo) throws jakarta.jms.JMSException
      Sets the destination to which a reply to this message should be sent.

      The replyTo 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 can be either a Queue or a Topic.

      Messages with a null replyTo value are called JMS datagrams. Datagrams might contain a notification of some change in the sender (i.e. they signal a sender event) or they might just contain some data the sender thinks is of interest.

      Messages with a replyTo value are typically expecting a response. A response is optional: it is up to the client to decide. These messages are called JMS requests. A message sent in response to a request is called a reply.

      In some cases a client might wish to match a request it sent earlier with a reply it has just received. This can be done using the JMSCorrelationID.

      Specified by:
      setJMSReplyTo in interface jakarta.jms.Message
      Parameters:
      replyTo - where to send a response to this message
      Throws:
      jakarta.jms.JMSException - if an internal error occurs
    • setJMSTimestamp

      public void setJMSTimestamp(long timestamp) throws jakarta.jms.JMSException
      Sets the message timestamp.

      Providers set this field when a message is sent. This operation can be used to change the value of a message that has been received.

      Specified by:
      setJMSTimestamp in interface jakarta.jms.Message
      Parameters:
      timestamp - the timestamp for this message
      Throws:
      jakarta.jms.JMSException - if an internal error occurs
    • setJMSType

      public void setJMSType(String type) throws jakarta.jms.JMSException
      Sets the message type.

      The type header field contains the name of a message's definition. JMS clients should assign a value whether the application makes use of it or not. This insures that it is properly set for the provider to use it, if required.

      This method must only be used with JMSBytes or JMSText messages. Use with other types of JMS Message will throw an exception with error code MQJMS_EXCEPTION_BAD_VALUE (JMSCMQ1006).

      Specified by:
      setJMSType in interface jakarta.jms.Message
      Parameters:
      type - the class of message
      Throws:
      jakarta.jms.JMSException - if the type is invalid
