Tools. This shell is the default shell for the Preview Server, which is a miniature instance of My webMethods Server hosted inside Software AG Designer that enables developers to preview portlets as they build them.

System. The system uses this portlet to deliver My webMethods Server and task e-mail notifications using the SMTP protocol.

System. Administrators use this portlet to display the portlet view for any My webMethods Server thing that does not have any other portlet view configured for it. The Pseudo Portlet portlet displays a view that includes the icon for the My webMethods Server thing, its name and description, and a link to the thing.

System. End users implicitly use this portlet when accessing a shortcut, which is a reference to an object (e.g., folder, page, portlet) in My webMethods Server. This portlet is part of the core system components. Users should not attempt to publish or use a standalone Shortcut View portlet.

Thumbnailer. The system uses this portlet to create thumbnail images when end users select to display a thumbnail view of a My webMethods Server folder. This is a system portlet that cannot be published by an administrator, page developer, nor end user.

System. The system uses this web application to serve some secondary resources (for example, JavaScripts, cascading style sheets, and images) that are needed CAF controls to function.
