MIDletVendor

In the Java ME platform, MIDlet-Vendor (often referred to by the shorthand MIDletVendor) is a metadata attribute used in a MIDlet suite’s application descriptor. It specifies the vendor or publisher of the MIDlet suite and is part of the standard set of MIDP manifest attributes, alongside MIDlet-Name and MIDlet-Version. The attribute is optional and intended for informational and organizational purposes rather than for programmatic control.

The value of the MIDlet-Vendor attribute is placed in the JAR manifest (META-INF/MANIFEST.MF) as a line such as "MIDlet-Vendor: Example Corp". It is also carried in the JAD (Java Application Descriptor) used by some devices and distribution channels, appearing as a similarly named entry. Devices, stores, or profile managers may display or sort applications by vendor, aiding in user recognition and management of installed MIDlets.

Usage considerations include that the field is purely metadata. It does not affect the execution of the MIDlet and is not used for security or permissions by the VM. Because it is optional, some MIDlet suites may omit it; in such cases, vendor-related display or filtering may be less informative.

Example: MIDlet-Vendor: Acme Mobile Ltd.
