Applet Manifest

This page provides an overview of the applet manifest's importance in an applet, and how it governs the applet's access to DAL features. For a list of fields in the manifest, see the Applet Manifest guidelines page.
Every trusted application includes what is known as an applet manifest. This file contains the applet's metadata: the supported firmware versions, the list of Java* classes the applet has permission to access, the applet's heap size, and so on. Some of the manifest fields are merely descriptive; others modify the applet's behavior. The contents of the applet manifest determine whether the applet has permission to access any or all of the other features in this section.
The contents of the manifest are verified with each signing request and this information is signed in the trusted application itself.
Some of the manifest fields are available to the host software to identify the trusted application that it is currently communicating with while some of the fields are internal to help the user further notate a project.
Use the Intel® DAL Manifest Editor, which comes as part of the Intel DAL Eclipse* plugin, to edit the editable fields in a manifest, if needed.  The Intel DAL Manifest Editor checks the validity of each value as well as also checks compatibility between the FW version and the API version used in a trusted application.
