‘Hello world!’ type test

The following scenario creates a single-component Job, where tMsgBox is used to display the pid (process id) in place of the traditional
“Hello World!” message.

Setting up the Job

Drop a tMsgBox component from the
Palette to the design workspace.
Define the dialog box display properties:

‘Title’ is the message box title, it can be any variable.
In the Message field, enter "Current date is: "
between double quotation marks. Then
click CTRL+Space to display the autocompletion list and select the following
system routine, Talend Date.getCurrentDate. Put brackets around
this routine.

Executing the Job

Switch to the Run tab to
execute the Job defined.

The Message box displays the message and requires the user to click OK to go to the next component or end the Job.

After the user clicked OK, the
Run log is updated accordingly.
