In netbeans, Tools > Java Platforms >Select Add Platform >Select Java ME MIDP platform emulator > select the one you installed now (Wireless Toolkit (location)) Share. Jan 02,  · The first thing to do is to create a Java ME mobile application (MIDlet). open NetBeans environment; choose File -> New Project; in Java ME category select a Mobile Application .

The Java ME project development support for NetBeans enables you to create applications for mobile devices with the following features:. A MIDlet suite can be built, executed, and deployed to mobile devices. The Java Application Descriptor File. When an application is downloaded to a device, the descriptor is downloaded and read before the JAR file that contains the Java ME Embedded application. This enables the device to confirm that space exists for the application, and confirms that the full application should be downloaded.

An emulator simulates how your application will operate on a specific type of mobile device such as standard and touch screen mobile phones. Emulator platforms include specific device examples, or skins, that simulate the operations of a specific device. Unified Emulator Interface UEI is a common set of standards specifying command-line access to emulator functionality.

The UEI allows IDE manufacturers to write to a single interface and, with little or no effort, be able to support emulators from many different companies. This support simulates the complete lifecycle of an application, starting from the Over-The-Air OTA Provisioning from a web site, installing and verifying, running, updating, and removing your application without involving an external web server.

A Java Application Fo file. This file contains a predefined set of attributes denoted by names that begin with MIDlet- that allows Application Management Software to identify, retrieve, and install the MIDlets.

Java ME Embedded projects are executed through an emulator platform, which simulates the execution of the application on a specific mobile device. Using project configurations and preprocessor code blocks, you can define conditions for multiple devices in a single set of code, enabling you test and produce MIDlet suites for each device. A project is a group of source 2jme and the settings with which you build, run, and debug those source files.

In the IDE, all Java development has to take place within a project. Within a Java ME Embedded project, you can create multiple project configurations that customize your MIDlet for different types of mobile devices.

Creates a build script that contains actions for running, compiling, debugging, and building Javadoc. There are differences, however, in the build and dist folders to accommodate the MEEP build process. The logical view of the project, shown in the Projects window, provides a hierarchy of sources and resources which reflects the type craete project and its contents. The Source Packages node encapsulates all the How to create j2me application in netbeans packages of the project.

Right-clicking on the Source Package node and creste New lets you add new file templates to your application. When a project is created, the following folders are created under build shown in the Files window :.

The IDE manages applications in projects. To create a new application, you inn first create and configure a new project. Use the New Project wizard or the project properties to create multiple configurations that enable you to simultaneously build and deploy your application to a range of platforms and devices.

With project templates, the IDE controls all aspects of how your application is built, run, and debugged. You set a project's source directory, classpath, emulator platform, and other project settings when creating iin project and in the Project J2ke dialog box. Embedded Application. Specify the name of the project and where to create it.

The IDE creates the project folder in the specified location. Click Next. Specify the emulator platform for the project. The emulator platform determines the execution environment for your project. You can also generate a MIDlet in the project. If you are setting the MIDlet properties for a project configuration other than the default configuration, you must uncheck the Use Values from "DefaultConfiguration" checkbox at the top of the page. Click the Add button. This opens the Add MIDlet dialog.

The dialog lists the MIDlets available in the project. The push registry allows MIDlets to be launched in response to an incoming network connection. When a MIDlet registers for push notifications, the device software is instructed to listen for incoming network connections and launch the MIDlet, if appropriate.

A MIDlet can register for push connections at runtime using static apllication in javax. A more common approach is to register at installation using properties contained in the application descriptor JAD file. This approach allows the AMS to ensure that how to create j2me application in netbeans MIDlet can be registered, and to cause the installation to fail if there are registration conflicts for example, if another MIDlet how to run a 400 meter already registered for the same socket connection.

A MIDlet suite can have multiple push registrations. Push registry configuration is only available for projects whose profile version is set to MDP 2. This opens the Project Properties dialog. Sender IP. A valid sender that can how to setup vpn router the associated MIDlet. If datagram or socket connections are used, the value how to create j2me application in netbeans Allowed Sender can be a numeric IP address.

Connection String. A connection string that identifies the connection protocol and port number. If your MIDlet suite needs to access certain protected APIs for example, network connectionsthe MEEP 8 ot architecture requires that the connection grant permission for access. You can also define optional permissions to limit access to sensitive data or functionality with the attribute MIDlet-Permissions-Opt.

During MIDlet suite installation, the MEEP compares the permissions requested with the permissions in the destination protection domain. If the required permissions can not be granted, the application will not be installed. During what is a backend server, if a required permission is denied, an exception is returned.

If an optional permission is denied, the application might continue to function, although its functionality would be limited. Permissions have the same naming structure as a Java class. For instance, javax. In the API Permissions table, check the Required box if you want installation to fail in the event that permission cannot be granted. You can add, cfeate, how to create j2me application in netbeans delete the attributes of a MIDlet suite for the active project configuration, and determine the order in which MIDlets are shown in a MIDlet suite.

Any class added to the project that extends MIDlet spplication or indirectly will be automatically be added to the Application Descriptor. Under Categories, select Application Descriptor. Select the MIDlets tab. Select a midlet and click the Edit button. This opens the Edit MIDlet dialog. To change the order in which a MIDlet is shown:. Select an attribute and click the Move Up or Move Down button.

In the Project Properties dialog, select Attributes. The Application Descriptor page enables you to add, edit, or remove the list of attributes that allow application management software to identify, retrieve, and install the MIDlets of a MIDlet suite. The Add Attributes dialog opens. Choose an attribute from the combo box. Then add a value for the attribute.

Note that the list of available attributes is dependent upon the MEEP version supported by the project configuration, as set in the Platform properties.

You can also add user-defined attributes by entering the attribute in the combo box. To avoid errors in verification, make sure all required attributes have a defined value. For each of your projects, you can produce a ceeate of Javadoc HTML pages that describe the project's classes, inner classes, interfaces, constructors, methods, and fields. The Javadoc is constructed from the structure of your code and the Javadoc comments embedded in your code. To set the javadoc generation properties:.

The IDE builds its project infrastructure directly on top of Apache Ant, the leading build tool for Java applications. To create JAR files for multiple devices at once:. To view and customize the build options for a project configuration:. Customize javac options for generating debugging information, optimizing the compilation, and reporting the use of deprecated APIs. The active project configuration is listed in the Configuration drop down menu on the Platform panel of the Project Properties dialog.

Generate Debugging Info. If checked, the compiler generates line numbers and source applicayion information. This is the -g option in javac. If unchecked, no debugging information is generated ho.

Compile with Optimization. If checked, the compiled application is optimized for execution. This is the -O option in javac. Optimizing can slow down compilation, produce larger class files, and make the program how to get gmail passwords to debug.

If checked, the compiler lists each use or override of how to create j2me application in netbeans deprecated member or class. This is the -deprecated option in javac. If unchecked, the compiler shows only the names of source files that use or override deprecated members or classes.

You can also set the default encoding used by the preprocessor and compiler in the encoding field. All other debug blocks are commented out. If you choose a pre-defined level from the drop-down menu, the preprocessor how to test silver with acid out debug blocks on lower levels, as defined by the following hierarchy:.
