JMSReceiver

Using the Java Message System (JMS), receives messages from a message broker.

Working with JMS

For information about configuring FME to communicate with JMS-compliant message brokers, see Working with JMS.

Usage Notes

The performance of this transformer is dependent on the amount of memory allocated to the Java Virtual Machine (JVM). The following environment variables allow you to specify memory available to Java Plugins:

  • FME_JVM_MIN_HEAP_SIZE: Initial heap size for initializing the JVM. If unset, the default value is 1024K.
  • FME32_JVM_MIN_HEAP_SIZE: Same as FME_JVM_MIN_HEAP_SIZE, but applies to 32-bit FME Desktop on Windows, and if set, takes precedence over FME_JVM_MIN_HEAP_SIZE.

These variables must be set in multiples of 1024 and greater than 1 MB. To indicate kilobytes, megabytes, or gigabytes, append k or K, m or M, or g or G respectively. For example, any of these values is acceptable:

6291456

6144k

6m

  • FME_JVM_MAX_HEAP_SIZE: Maximum heap size for initializing the JVM. If unset, the default value is 16384K.
  • FME32_JVM_MAX_HEAP_SIZE: Same as FME_JVM_MAX_HEAP_SIZE, but applies to 32-bit FME Desktop on Windows, and if set, takes precedence over FME_JVM_MAX_HEAP_SIZE.

These variables must be set in multiples of 1024 and greater than 2 MB. To indicate kilobytes, megabytes, or gigabytes, append k or K, m or M, or g or G respectively. For example, any of these values is acceptable:

83886080

81920k

80m

Note: To pass additional parameters used by FME to the Java Virtual Machine, use the JAVA_TOOL_OPTIONS environment variable.

Parameters

Connection Parameters

ClosedProvider Type or Context

The message broker to connect to, or the initial context factory if the broker is not listed.

ClosedProvider URL

The URL of the folder containing connection details for the JMS provider.

ClosedAdditional Provider Properties

Any additional provider-specific properties, in the form key=value. Specify multiple pairs on separate lines, using the Text Editor.

In most cases, this field is not required. The JMS brokers tested by Safe, including Apache ActiveMQ, IBM Websphere MQ, and Oracle WebLogic JMS, do not require any additional properties to establish a connection.

Note: Note: When connecting to ACTIVEMQ, do not specify any failover transport options here. Instead, specify them directly in the Provider URL field. For example: failover:(tcp://primary:61616,tcp://secondary:61616)?randomize=false

ClosedConnection Factory

The name of the connection factory object.

ClosedUsername

An authenticating username.

ClosedPassword

An authenticating password.

ClosedDestination(s)

The names of the destination objects. These correspond to queues and/or topics.

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
