System applications
A system application is a Java EE enterprise application that is central to a WAS product.
Examples of system applications include isclite, managementEJB and filetransfer.
Because a system application is an important part of a WAS product, a system application is deployed when WAS is installed and is updated only through a product fix or upgrade. For some system applications, such as filetransfer, users cannot change the metadata for the system application, unless the metadata assigns users and groups for security purposes. For these applications, non-security related metadata such as its Java EE bindings or extensions must be updated through a product fix or upgrade.
System applications are not shown in the list of installed applications on the console Enterprise Applications page, or through wsadmin and Java APIs, to prevent users from accidentally stopping, updating or removing the system applications.
Note that Java EE Samples are not system applications even though they are provided as part of a WAS product. Similarly, applications that support changes to their metadata are not system applications.
