Hitonic MIDlet Protector modifies MIDlet JAR files and sets various limitations on launching MIDlets (a simple startup banner, a simple launch password, runtime limitations, launch date limitations, launch count limitations). This tool is useful to protect mobile phone applications created automatically, for example, through bookreaders. The interface is easy to use. You only need to specify the MIDlet JAR file, specify the type of protection with its options and click the PROTECT button. The SIMPLE BANNER protection displays additional information during the MIDlet launch. There are some options concerning displaying the banner text. The information is displayed for the specified time or until the key is pressed. If the SIMPLE PASSWORD type of protection is used, launching the MIDlet will require the password. There is an option that describes the MIDlet lock type. The lock type may be ONCE (the MIDlet first launch) or ALWAYS (every time the MIDlet is launched). About the RUNTIME LIMITATION protection. When the MIDlet is launched for the first time, the time and date of the launch will be saved. There is an option that defines the number of days the MIDlet can be launched for. After this time expires, it will be impossible to launch the MIDlet. The additional information screen can be displayed during the MIDlet launch. The "Last work date" option is available if you use the LAUNCH DATE LIMITATION type of protection. It will be impossible to launch the MIDlet after that date. Also the additional information screen can be displayed during the MIDlet launch. The "Number of launches" option is available if you use the LAUNCH COUNT LIMITATION protection. After the MIDlet has been launched the specified number, it will be locked. Also the additional information screen can be displayed during the MIDlet launch.
