How to install Java application in your phone?

Sometimes, you might need to install a Java application from your PC to the phone. You may have obtain the JAD and JAR files by email, download them manually from web site, or write it yourself or, perhaps your phone does not support General Packet Radio Service (GPRS) or WAP services to get the applications from internet. In these cases, you may use the Nokia PC Suite to install a pair of JAD and JAR files from your Windows-based PC to the phone. The Nokia Application Installer program in the PC Suite allows you to choose a JAR file from the local hard drive. Once you click the green arrow to install the JAR file to the phone, the PC Suite searches the directory the JAR file resides in for a matching JAD file of the same name. If such a JAD file is found, the JAD and JAR pair will be installed automatically. If the JAD file is not found, you can install the JAR file by itself (the JAR-only installation).

If you use a Mac computer or simply cannot get the Nokia PC Suite working on your computer, you can send the JAR file over to the phone via a local connection, such as Bluetooth or Infrared. The file shows up in your phone's messaging Inbox. When you open the message, the AMS is invoked to install the application . This method is one way to perform a JAR-only installation.
