Deleting a servlet
Servlet Management is only available for Pega Cloud, and allows you to add, modify, and disable servlet configurations without editing the web.xml file. You can delete user-defined servlets that are no longer used in the system and that you do not need to keep within the system.
In the header of Dev Studio, click.
Identify the servlet that you want to delete, click the More on the right side of the row, and select Delete.
In the Confirm delete servlet dialog box, click Delete.
For the changes to take effect, you must restart your entire environment.
