tJMSInput – Docs for ESB 6.x

tJMSInput

Creates an interface between a Java application and a Message-Oriented middleware
system.

Using a JMS server, tJMSInput makes it possible to
have loosely coupled, reliable, and asynchronous communication between different
components in a distributed application.

Depending on the Talend solution you
are using, this component can be used in one, some or all of the following Job
frameworks:

tJMSInput Standard properties

These properties are used to configure tJMSInput running in the Standard Job framework.

The Standard
tJMSInput component belongs to the Internet family.

The component in this framework is generally available.

Basic settings

Module List

Select the library to be used from the list.

Context Provider

Type in the context URL, for example com.tibco.tibjms.naming.TibjmsInitialContextFactory. However,
be careful, the syntax can vary according to the JMS server used.

Server URL

Type in the server URL, respecting the syntax, for
example tibjmsnaming://localhost:7222.

Connection Factory JDNI Name

Type in the JDNI name.

Use Specified User Identity

If you have to log in, select the check box and type in
your login and password.

To enter the password, click the […] button next to the
password field, and then in the pop-up dialog box enter the password between double quotes
and click OK to save the settings.

Enable Durable Subscription

Select this check box to enable the durable
subscription.

ClientID

Enter the client ID for the durable subscription.

This field is available only when the Enable Durable Subscription check box is
selected.

Subscriber Name

Enter the subscriber name for the durable
subscription.

This field is available only when the Enable Durable Subscription check box is
selected.

Use JNDI Name Lookup Destination

Select this check box to look up a destination with the JNDI (Java Naming
and Directory Interface) name.

Message Type

Select the message type, either: Topic or Queue.

Message From

Type in the message source, exactly as expected by the
server; this must include the type and name of the source. e.g.: queue/A
or topic/testtopic

Note that the field is case-sensitive.

Timeout for Next Message (in sec)

Type in the number of seconds before passing to the next
message.

Maximum Messages

Type in the maximum number of messages to be
processed.

Message Selector Expression

Set your filter.

Processing Mode

Select the processing mode for the messages.

Raw Message or Message Content

Schema and Edit Schema

A schema is a row description. It defines the number of fields (columns) to
be processed and passed on to the next component. The schema is either Built-In or stored remotely in the Repository.

The schema of this component is read-only. You can click Edit schema to view the schema.

Advanced settings

Properties

Click the plus button underneath the table to add lines that contains
username and password required for user authentication.

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at a Job
level as well as at each component level.

Global Variables

Global Variables

ERROR_MESSAGE: the error message generated by the
component when an error occurs. This is an After variable and it returns a string. This
variable functions only if the Die on error check box is
cleared, if the component has this check box.

NB_LINE: the number of rows read by an input component or
transferred to an output component. This is an After variable and it returns an
integer.

A Flow variable functions during the execution of a component while an After variable
functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl +
Space
to access the variable list and choose the variable to use from it.

For further information about variables, see
Talend Studio

User Guide.

Usage

Usage rule

This component is generally used as an input component. It must be
linked to an output component.

Limitation

Make sure the JMS server is launched.

Due to license incompatibility, one or more JARs required to use this component are not
provided. You can install the missing JARs for this particular component by clicking the
Install button on the Component tab view. You can also find out and add all missing JARs easily on the
Modules tab in the
Integration
perspective of your
studio. You can find more details about how to install external modules in Talend Help Center (https://help.talend.com).

tJMSInput properties for Apache Spark Streaming

These properties are used to configure tJMSInput running in the Spark Streaming Job framework.

The Spark Streaming
tJMSInput component belongs to the Messaging family.

The component in this framework is available only if you have subscribed to Talend Real-time Big Data Platform or Talend Data
Fabric.

Basic settings

Module List

Select the library to be used from the list.

Context Provider

Type in the context URL, for example com.tibco.tibjms.naming.TibjmsInitialContextFactory.
However, be careful, the syntax can vary according to the JMS server
used.

Server URL

Type in the server URL, respecting the syntax, for example tibjmsnaming://localhost:7222.

Connection Factory JDNI Name

Type in the JDNI name.

Use Specified User Identity

If you have to log in, select the check box and type in your login
and password.

To enter the password, click the […] button next to the
password field, and then in the pop-up dialog box enter the password between double quotes
and click OK to save the settings.

Message Type

Select the message type, either: Topic or Queue.

Message From

Type in the message source, exactly as expected by the server;
this must include the type and name of the source. e.g.: queue/A or
topic/testtopic

Note that the field is case-sensitive.

Timeout for Next Message (in sec)

Type in the number of seconds before passing to the next
message.

Raw Message or Message Content

Schema and Edit
Schema

A schema is a row description. It defines the number of fields (columns) to
be processed and passed on to the next component. The schema is either Built-In or stored remotely in the Repository.

The schema of this component is read-only. You can click Edit schema to view the schema.

Advanced settings

Use SSL/TLS

Select this check box to enable the SSL or TLS encrypted connection.

Then you need to use the tSetKeystore
component in the same Job to specify the encryption information.

For further information about tSetKeystore, see tSetKeystore.

Properties

Click the plus button underneath the table to add lines that
contains username and password required for user
authentication.

Usage

Usage rule

This component is used as a start component and requires an output link.

This component, along with the Spark Streaming component Palette it belongs to, appears
only when you are creating a Spark Streaming Job.

Note that in this documentation, unless otherwise explicitly stated, a scenario presents
only Standard Jobs, that is to say traditional
Talend
data
integration Jobs.

Spark Connection

You need to use the Spark Configuration tab in
the Run view to define the connection to a given
Spark cluster for the whole Job. In addition, since the Job expects its dependent jar
files for execution, you must specify the directory in the file system to which these
jar files are transferred so that Spark can access these files:

  • Yarn mode: when using Google
    Dataproc, specify a bucket in the Google Storage staging
    bucket
    field in the Spark
    configuration
    tab; when using other distributions, use a
    tHDFSConfiguration
    component to specify the directory.

  • Standalone mode: you need to choose
    the configuration component depending on the file system you are using, such
    as tHDFSConfiguration
    or tS3Configuration.

This connection is effective on a per-Job basis.

No scenario is available for the Spark Streaming version of this component
yet.
