Java applet, JAR file generation method, JAR file generation program, and JAR file generation device

A JAR file generation method in which a computer performs processing for generating a JAR file including a Java applet which causes the computer to execute plural predetermined Java applet programs, wherein the computer executes:

• an identification information generation step that generates identification information for detecting alteration to deployment information, based on the deployment information defining respective locations of the plural predetermined Java applet programs;
• and
• a JAR file generation step that generates a JAR file including the deployment information and the identification information, based on the deployment information and the identification information, the JAR file defining the identification information as a class file in a predetermined package.
