The jms-enqueue element allows you to perform a enqueue on a JMS destination. It is used by Channel and routed-dequeue.

GVBuffer fields will be made available through the JMS message properties:

Field JMS
system SYSTEM
service SERVICE
id ID
retCode RET_CODE
properties p$<property name> (only GVBuffer properties with names that are valid Java identifier are managed)

It has the attributes:

Attribute Type Description
type fixed This attribute must assume the value enqueue.
class fixed This attribute must assume the value it.greenvulcano.gvesb.virtual.j2ee.JMSEnqueueOperation.
name required Operation name. Used in the Flow section to associate workflow nodes to VCL operations.
connection-factory required JMS connection factory JNDI name.
destination-name required Destination JNDI name. Set appropriately the destination-type parameter.
destination-type optional Destination type. Default: queue.
The attribute's admitted values are:
  • queue
  • topic
transacted optional Specifies whether the enqueue has to open his own transaction or fall in a global transaction.
  • true open his own transaction and do not fall in the global transaction.
  • false fall in the active global transaction. Must be used a XA connection factory.
This parameter is not relevant if the connection factory is not XA. Default: false.
acknowledge-type optional In transactional enqueue acknowledgment is managed by the application server.
This parameter is meaningful only for non-transactional enqueue and can take the following values:
  • auto-acknowledge: the acknowledgment from application server is automatically given upon delivery of the message.
  • client-acknowledge: the client must explicitly acknowledgment the message.
  • dups-ok-acknowledge: allows the JMS server to perform optimizations on the logic of acknowledgment messages, but can cause the redelivery of messages. Should only be used with systems that are tolerant to duplicated message. Default: auto-acknowledge
delivery-mode optional Specifies whether the JMS server must file on a persistent store the message before returning to the caller.
Sending messages persistent slightly affects the performance but provides greater guarantees of delivery. The possible values for this parameter are:
  • persistent : guarantees delivery. Default value
  • non-persistent: don't guarantees delivery
priority optional Message priority. The messages with higher priority will be received before messages with lower priority. The priorities set for JMS ranging from 0 (lowest priority) to 9 (highest priority). The default priority of JMS messages is 4.
time-to-live optional Lifetime of sent messages, in milliseconds.
Upon expiration of the time-to-live the JMS server is allowed to discard the message without delivering it. If not specified it is assumed a time-to-live of one year.
use-vcl-pool optional Indicates whether to use connection pooling capabilities of the VCL. Set to false if the container provides pooling capabilities. Default: true
invalidate-conn-on-pool-insertion optional Indicates whether connections should be marked as invalid before reinsertion on the pool. Is significant only if the pooling feature is enabled. Default: false
ref-dp optional Name of Data Provider to use. This Data Provider will return the JMS Message to send.
dump-message optional If true the message to be enqueued is dumped on log file, at DEBUG severity level. Default false
Attribute Type Description
decorate-message optional If true the message to be enqueued is enriched with input GVBuffer properties value. Default true. The attribute's admitted values are:
  • true
  • false
