In the aforementioned block construction, the controller may perform a function of the JAVA manager These are separately constructed and illustrated in order to distinguish and describe respective functions in an exemplary embodiment of the present invention.
Exemplary embodiments of the present invention protect files of a MIDlet suite from a malicious loss or damage while enabling execution in various apparatuses i. Exemplary embodiments of the present invention have an advantage of enabling safe management because files of a MIDlet suite are protected by DRM, even upon transmission to a different apparatus that is capable of protecting MIDlet suites. Exemplary embodiments of the present invention enable a user to maintain information generated in a J2ME application program while it is used in several apparatuses.
In addition, exemplary embodiments of the present invention prevent a user from decompiling a class code within a. Exemplary embodiments of the present invention have an advantage of being capable of using their own billing system for DRM without having to implement a purchase system of a J2ME application program for demonstration.
Exemplary embodiments the present invention have an advantage of being capable of easily sharing a JAVA game or application program with a different user, and using a forwarding function with increased convenience. Exemplary embodiments of the present invention have an advantage that a content provider may spread a corresponding JAVA game or application program to more users. In addition, exemplary embodiments of the present invention have an advantage of including a. While the invention has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.

Hi all I've just bought my first Motorola mobile ever, the C I've been a loyal Nokia user for many years and felt like a change. I rang Motorola and they advised me that I must purchase the cable, driver and the Mobile Phone Tools software from a Motorola dealer. I have a USB cable that I use for my digital camera. Once the application is installed, choose the application from the list and choose Launch from the menu.
Running an application on a real device depends heavily on the device itself. Consult your device documentation for information. This is useful for running MIDlet suites from the toolkit user interface even when you don't have the source code available. You can use the toolkit to easily manipulate the attributes in the descriptor, or you can run the project and use the toolkit's monitoring tools described in Chapter 5 to scrutinize its behavior.
Navigate to the descriptor you wish to use and click Open. Note that the descriptor and the JAR file must be in the same directory. An obfuscator is a tool that reduces the size of class files. MIDlet suites need to be compact, both to minimize download times and to comply with sometimes stringent limits on JAR file size imposed by manufacturers or carriers.
You can use an obfuscator in the packaging step of the development cycle. All you need to do is download ProGuard and put it in a place where the toolkit can find it. If you are comfortable with the terms of the license, you can download and use ProGuard free of charge. Follow these steps to install ProGuard:. Uncompress the proguard. In some cases, you need to provide a script file that controls how the obfuscator works.
If you are loading classes using Class. To call the script file you must be able to modify your own copy of the file ktools. Create a script file using a text editor, then save it under the project's main directory.
Consult the ProGuard documentation for information on script files. Next, tell the toolkit how to find this file. To do this, edit the ktools. Add a line as follows:. Replace scriptfile with the name you used for the script file. You must quit and restart the toolkit for the change to take effect. A variation on running your application is running it with a debugger. A debugger enables you to monitor the running application more closely, set breakpoints, and examine variables.
You must supply your own debugger. You can use the jdb debugger from the Java SE platform or another debugger of your choice. Click Debug. The emulator begins running and waits for a connection from a debugger. MIDlet abstract class and implement certain methods in that class.
A MIDlet runs in a controlled environment and therefore must implement certain methods that allow the application manager which installs and runs the MIDlet to control the behavior of the MIDlet.
These methods are known as life cycle methods , since they reflect various states in which a MIDlet can be. The state chart in Figure shows the possible state transitions of a MIDlet, this time with the addition of the methods that the Java Manager will call inside the MIDlet code during those transitions. Here, the javax. MIDlet abstract class defines three life cycle methods that are called during the state transitions: pauseApp , startApp , and destroyApp.
These three methods were present in the example we developed in Chapter 1. The responsibilities for these three life cycle methods are as follows. This method indicates that the MIDlet is moving from a paused state to an active state. Here, the MIDlet will typically initialize any objects that are required while the MIDlet is active, and set the current display. This method is called when the MIDlet is moving from an active state to a paused state.
This means that it will pause any threads that are currently active, as well as optionally setting the next display to be shown when the MIDlet is re-activated. Data can be persisted, if necessary, and retrieved later when the MIDlet is activated again. This method indicates that the MIDlet is moving to the destroyed state.
