Component family




tRouteInput accepts messages from a Route.


tRouteInput allows you to exchange messages between a Data Integration Job and a Mediation Route.

Basic settings

Input 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.

Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

  • View schema: choose this option to view the schema only.

  • Change to built-in property: choose this option to change the schema to Built-in for local changes.

  • Update repository connection: choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion. If you just want to propagate the changes to the current Job, you can select No upon completion and choose this schema metadata again in the [Repository Content] window.



Built-in: No property data stored centrally.



Repository: Select the Repository file where Properties are stored.



Enter the message parameters corresponding to the columns you defined in the schema dialog box via the Edit schema button using the Simple Expression Language.

Advanced settings

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 

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.

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.


This component can be used as starter component and has an output. It is mandatory that a tRouteInput component is used in the Data Integration Job to be called by a Route using the cTalendJob component. The reason for it is that this will prevent the referenced Job from starting automatically when deployed in Talend Runtime. Instead it will only start when it gets called by the Route. For more information about how to use the cTalendJob component, see Talend ESB Mediation Components Reference Guide.


The Job using a tRouteInput must be launched only within a Route using the cTalendJob component.
