    A .jar file is a file format that puts together numerous files into one file. Normally, a .jar file is used by software developers for Java classes. When you install an application the security of the application is checked during the installation. Your device can not verify the supplier of the application unless it has a digital signature or Certificate which may cause the error.

    Normally you only have to send the jar-file to the phone and execute them. They will install. A jar file is a compressed file probably containing the setup files you are looking for. You need a tool to un-compress (extract) the files.

    Jar files are Java Archive files and are used to hold multiple files for java-related applications such as browser add-ons, applets or plug-ins. Make sure that the date on your phone is set to the correct and All the messages you get as you install the .jar file such as untrusted, not compatible, etc just click OK/YES and it will install ok.
