17 Prevent Downloading of Large Java MIDlets

17.1 Overview

This feature is a flexible way of preventing the large JAR files OTA download. The current functionality is as follows:

∙The user is able to download any JAR file independently from its file size via the WAP browser. In some cases the MIDlet can not be executed properly due to the limited heap memory size of a Java enabled phone. In this case the user is charged for the data transfer (not for the event) and in some cases this charge will be higher than the cost of MIDlet itself.

In order to let the different operators utilize this feature there must be the ability to use flex database element to limit the maximum size of the JAR file. The appropriate notice shall be displayed to inform the user that the maximum JAR file size is ex- ceeded and downloading is rejected. The maximum JAR file size value shall come dir- ectly from a customer requirement or product team.

There may be 2 types of MIDlets download:

∙JAR-only file download

∙JAR/JAD file download

This feature does not consider JAR-only download. The behavior in this case is spe- cified by "Java ME™ Download MIDlet Through Browser" feature.
