System applications
A system application is a J2EE enterprise application that is central to a WAS product.
Examples of system applications include adminconsole and filetransfer.
Because a system application is an important part of a WebSphere Application Server product, a system application is deployed when the product is installed and is updated only through a product fix or upgrade. Users cannot change the metadata for a system application such as its J2EE bindings or J2EE extensions, unless the metadata assigns users and groups for security purposes. Non-security related metadata requiring a change 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 application programming interfaces, to prevent users from accidentally stopping, updating or removing the system applications.
Note that J2EE 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.
