This scenario uses two components, a tLibraryLoad and a tJava. The goal of this scenario is to check the format of an e-mail address and verify whether the format is valid or not.

Setting up the Job

  1. In the Palette, open the Custom_Code folder, and slide a tLibraryLoad and tJava component onto the workspace.

  2. Connect tLibraryLoad to tJava using a Trigger > OnSubjobOk link.

Configuring the tLibraryLoad component

  1. Double-click on tLibraryLoad to display its Basic settings. From the Library list, select jakarta-oro-2.0.8.jar.

  2. In the Import field of the Advanced settings tab, type import org.apache.oro.text.regex.*;

Configuring the tJava component

  1. Double-click on tJava to display its Component view.

  2. In the Basic settings tab, enter your code, as in the screenshot below. The code allows you to check whether the character string pertains to an e-mail address, based on the regular expression: "^[\\w_.-]+@[\\w_.-]+\\.[\\w]+$".

Job execution

Press F6 to save and run the Job.

The Console displays the boolean false. Hence, the e-mail address is not valid as the format is incorrect.
