org.mule.transport.jms
Class JmsMessageAdapter

java.lang.Object
  org.mule.transport.AbstractMessageAdapter
      org.mule.transport.jms.JmsMessageAdapter

All Implemented Interfaces:

Serializable, ThreadSafeAccess, MessageAdapter

public class JmsMessageAdapter
extends AbstractMessageAdapter

JmsMessageAdapter allows a DefaultMuleEvent to access the properties and payload of a JMS Message in a uniform way. The JmsMessageAdapter expects a message of type javax.jms.Message and will throw an IllegalArgumentException if the source message type is not compatible. The JmsMessageAdapter should be suitable for all JMS Connector implementations.

Constructor Detail

JmsMessageAdapter

public JmsMessageAdapter(Object message)
                  throws MessagingException

Throws:

MessagingException

JmsMessageAdapter

protected JmsMessageAdapter(JmsMessageAdapter template)

Method Detail

setSpecification

public void setSpecification(String newSpec)

getPayloadAsString

public String getPayloadAsString(String encoding)
                          throws Exception

Converts the message implementation into a String representation

Parameters:

encoding - The encoding to use when transforming the message (if necessary). The parameter is used when converting from a byte array

Returns:

String representation of the message payload

Throws:

Exception - Implementation may throw an endpoint specific exception

getPayloadAsBytes

public byte[] getPayloadAsBytes()
                         throws Exception

Converts the message implementation into a String representation

Returns:

String representation of the message

Throws:

Exception - Implemetation may throw an endpoint specific exception

getPayload

public Object getPayload()

Returns:

the current message

getUniqueId

public String getUniqueId()

Specified by:

getUniqueId in interface MessageAdapter

Overrides:

getUniqueId in class AbstractMessageAdapter

setCorrelationId

public void setCorrelationId(String id)

Sets a correlationId for this message. The correlation Id can be used by components in the system to manage message relations

transport protocol. As such not all messages will support the notion of a correlationId i.e. tcp or file. In this situation the correlation Id is set as a property of the message where it's up to developer to keep the association with the message. For example if the message is serialised to xml the correlationId will be available in the message.

Specified by:

setCorrelationId in interface MessageAdapter

Overrides:

setCorrelationId in class AbstractMessageAdapter

Parameters:

id - the Id reference for this relationship

getCorrelationId

public String getCorrelationId()

Sets a correlationId for this message. The correlation Id can be used by components in the system to manage message relations.

The correlationId is associated with the message using the underlying transport protocol. As such not all messages will support the notion of a correlationId i.e. tcp or file. In this situation the correlation Id is set as a property of the message where it's up to developer to keep the association with the message. For example if the message is serialised to xml the correlationId will be available in the message.

Specified by:

getCorrelationId in interface MessageAdapter

Overrides:

getCorrelationId in class AbstractMessageAdapter

Returns:

the correlationId for this message or null if one hasn't been set

setReplyTo

public void setReplyTo(Object replyTo)

Sets a replyTo address for this message. This is useful in an asynchronous environment where the caller doesn't wait for a response and the response needs to be routed somewhere for further processing. The value of this field can be any valid endpointUri url.

Specified by:

setReplyTo in interface MessageAdapter

Overrides:

setReplyTo in class AbstractMessageAdapter

Parameters:

replyTo - the endpointUri url to reply to

getReplyTo

public Object getReplyTo()

Sets a replyTo address for this message. This is useful in an asynchronous environment where the caller doesn't wait for a response and the response needs to be routed somewhere for further processing. The value of this field can be any valid endpointUri url.

Specified by:

getReplyTo in interface MessageAdapter

Overrides:

getReplyTo in class AbstractMessageAdapter

Returns:

the endpointUri url to reply to or null if one has not been set

newThreadCopy

public ThreadSafeAccess newThreadCopy()

Specified by:

newThreadCopy in interface ThreadSafeAccess

Overrides:

newThreadCopy in class AbstractMessageAdapter
