Jobs using the Groovy language which is a simplified Java
syntax.

tGroovyFile allows you to call an
existing Groovy script.

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. 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.

Usage

Usage rule	This component can be used alone or as a subJob along with another component.
Limitation	Knowledge of the Groovy language is required.

Calling a file which contains Groovy code

This scenario uses tGroovyFile, on its
own. The Job calls a file containing Groovy code in order to display the file information in
the Console.

Setting up the Job

Open the Custom_Code folder in the Palette and drop a tGroovyFile component onto the workspace.

Configuring the tGroovyFile component

Double-click the component to display the Component view.
In the Groovy File field, enter the path
to the file containing the Groovy code, or browse to the file in your
directory. In this example, it is D:/Input/Ageducapitaine.txt, and the file contains the
following Groovy codes:

println("The captain is " + age + " years old")

1

println("The captain is " + age + " years old")
In the Variables table, add a line by
clicking the [+] button.
In the Name column, enter
“age”, and then in the Value column, enter 50.

Executing the Job

Press Ctrl+S to save your Job.
Press F6 or click Run on the Run tab to
execute the Job.

The Console displays the information
contained in the input file, to which the variable result is added.
