Nokia Phone AMS Installation Error: JAD and JAD Attribute do not match

What is JAD file

JAD or the Java Application Descriptor is an application for Mobile Phones in Java Platform Micro Edition or the Java ME. Java ME is a platform for mobile phones and devices or the so called Embedded Systems. It was develop by Sun Microsystems.

What is JAR file

JAR file is simply defined as Java Archive. These files are generally use by Java software developers to archive or combine files for installation or for distribution of Java Applications and Libraries. JAR files can be made through Zipping tools such as WINZIP or the JAR command.

What is Attribute

Attribute is the characteristics or properties of an object. It is commonly used in object programming to describe the property of an object. For example a text box has the property or an attribute of text, font, color, style, border and many more. It is the same with the attribute of the person for example a person who is the president, male, single and the like. This was used to identify characteristics, properties classification of an object.

Installing AMS associated with this error sometimes occurred in Nokia Phones. The error happens because of the attributes of download JAD file that is not match with the attribute on the installation file or the JAR file. This error seems like the installation version or the libraries on the installation file do not match with the application file. For instance the application file is in version 5 while the libraries on the distributed files are for version 5. And that’s what the system called does not match with the attribute.

As it was discussed, it sounds like we need to download both the Application file or the JAD and the distribution file or the JAR. Re-downloading of these files doesn’t fix the issue. The issue is in the cache saved in your mobile phone or in your Nokia Phone.

Before we dive-in into fixing the error, you must identify the attribute of your Phone or device first. Does your phone support the AMS application?
