Sink

jms (Sink)

JMS Sink allows users to subscribe to a JMS broker and publish JMS messages.

Syntax

@sink(type="jms", destination="<STRING>", connection.factory.jndi.name="<STRING>", factory.initial="<STRING>", provider.url="<STRING>", connection.factory.type="<STRING>", connection.username="<STRING>", connection.password="<STRING>", connection.factory.nature="<STRING>", @map(...)))

QUERY PARAMETERS

Name	Description	Default Value	Possible Data Types	Optional	Dynamic
destination	Queue/Topic name which JMS Source should subscribe to		STRING	No	Yes
connection.factory.jndi.name	JMS Connection Factory JNDI name. This value will be used for the JNDI lookup to find the JMS Connection Factory.	QueueConnectionFactory	STRING	Yes	No
factory.initial	Naming factory initial value		STRING	No	No
provider.url	Java naming provider URL. Property for specifying configuration information for the service provider to use. The value of the property should contain a URL string (e.g. "ldap://somehost:389")		STRING	No	No
connection.factory.type	Type of the connection connection factory. This can be either queue or topic.	queue	STRING	Yes	No
connection.username	username for the broker.	None	STRING	Yes	No
connection.password	Password for the broker	None	STRING	Yes	No
connection.factory.nature	Connection factory nature for the broker(cached/pooled).	default	STRING	Yes	No

Examples EXAMPLE 1

@sink(type='jms', @map(type='xml'), factory.initial='org.apache.activemq.jndi.ActiveMQInitialContextFactory', provider.url='vm://localhost',destination='DAS_JMS_OUTPUT_TEST', connection.factory.type='topic',connection.factory.jndi.name='TopicConnectionFactory')
define stream inputStream (name string, age int, country string);

This example shows how to publish to an ActiveMQ topic.

EXAMPLE 2

@sink(type='jms', @map(type='xml'), factory.initial='org.apache.activemq.jndi.ActiveMQInitialContextFactory', provider.url='vm://localhost',destination='DAS_JMS_OUTPUT_TEST')
define stream inputStream (name string, age int, country string);

This example shows how to publish to an ActiveMQ queue. Note that we are not providing properties like connection factory type

Source

jms (Source)

JMS Source allows users to subscribe to a JMS broker and receive JMS messages. It has the ability to receive Map messages and Text messages.

Syntax

@source(type="jms", destination="<STRING>", connection.factory.jndi.name="<STRING>", factory.initial="<STRING>", provider.url="<STRING>", connection.factory.type="<STRING>", worker.count="<INT>", connection.username="<STRING>", connection.password="<STRING>", retry.interval="<INT>", retry.count="<INT>", use.receiver="<BOOL>", subscription.durable="<BOOL>", connection.factory.nature="<STRING>", @map(...)))

QUERY PARAMETERS

Name	Description	Default Value	Possible Data Types	Optional	Dynamic
destination	Queue/Topic name which JMS Source should subscribe to		STRING	No	No
connection.factory.jndi.name	JMS Connection Factory JNDI name. This value will be used for the JNDI lookup to find the JMS Connection Factory.	QueueConnectionFactory	STRING	Yes	No
factory.initial	Naming factory initial value		STRING	No	No
provider.url	Java naming provider URL. Property for specifying configuration information for the service provider to use. The value of the property should contain a URL string (e.g. "ldap://somehost:389")		STRING	No	No
connection.factory.type	Type of the connection connection factory. This can be either queue or topic.	queue	STRING	Yes	No
worker.count	Number of worker threads listening on the given queue/topic.	1	INT	Yes	No
connection.username	username for the broker.	None	STRING	Yes	No
connection.password	Password for the broker	None	STRING	Yes	No
retry.interval	Interval between each retry attempt in case of connection failure in milliseconds.	10000	INT	Yes	No
retry.count	Number of maximum reties that will be attempted in case of connection failure with broker.	5	INT	Yes	No
use.receiver	Implementation to be used when consuming JMS messages. By default transport will use MessageListener and tweaking this property will make make use of MessageReceiver	false	BOOL	Yes	No
subscription.durable	Property to enable durable subscription.	false	BOOL	Yes	No
connection.factory.nature	Connection factory nature for the broker.	default	STRING	Yes	No

Examples EXAMPLE 1

@source(type='jms', @map(type='json'), factory.initial='org.apache.activemq.jndi.ActiveMQInitialContextFactory', provider.url='tcp://localhost:61616',destination='DAS_JMS_TEST', connection.factory.type='topic',connection.factory.jndi.name='TopicConnectionFactory')
define stream inputStream (name string, age int, country string);

This example shows how to connect to an ActiveMQ topic and receive messages.
