Applet, archive file generation method, archive file generation program, and archive file generation device

An archive file generation method in which a computer performs processing for generating an archive file including an applet which causes the computer to execute a plurality of predetermined applet programs, wherein the computer executes:

• generating identification information for detecting alteration to deployment information, based on the deployment information, the deployment information defining respective locations of the plurality of predetermined applet programs by using at least one of a uniform resource locator (URL) of an applet program of an external server and a path of an applet program on a local disk of the computer;
• and
• generating an archive file based on the deployment information and the identification information, wherein
• the archive file includes the applet, the plurality of predetermined applet programs, and the deployment information,
• the applet of the archive file includes a package comprising the identification information, a load program for loading the plurality of predetermined applet programs, and a startup program for starting up the load program as class files;
• and
• an electronic signature for certifying an origin of the archive file is attached to the archive file.

A computer-readable non-transitory recording medium having recorded thereon an archive file generation program that causes a computer to execute processing for generating an archive file including an applet which causes the computer to execute a plurality of predetermined applet programs, wherein the program causes the computer to execute a process comprising:

• generating identification information for detecting alteration to deployment information, the deployment information defining respective locations of the plurality of predetermined applet programs by using at least one of a uniform resource locator (URL) of an applet program of an external server and a path of an applet program on a local disk of the computer;
• and
• generating an archive file based on the deployment information and the identification information, wherein
• the archive file includes the applet, the plurality of predetermined applet programs, and the deployment information,
• the applet of the archive file includes a package comprising the identification information, a load program for loading the plurality of predetermined applet programs, and a startup program for starting up the load program as class files;
• and
• an electronic signature for certifying an origin of the archive file is attached to the archive file.

An archive file generation device that generates an archive file including an applet which causes a computer to execute a plurality of predetermined applet programs, the device comprising:

• a recording medium;
• and
• a processor coupled to the recording medium,
• wherein the processor executes a program stored in the recording medium to perform a process including:
• generating identification information based on deployment information, the deployment information defining respective locations of the plurality of predetermined applet programs by using at least one of a uniform resource locator (URL) of an applet program of an external server and a path of an applet program on a local disk of the computer;
• and
• generating an archive file based on the deployment information and the identification information, wherein
• the archive file includes the applet, the plurality of predetermined applet programs, the deployment information,
• the applet of the archive file includes a package comprising the identification information, a load program for loading the plurality of predetermined applet programs, and a startup program for starting up the load program as class files;
• and
• an electronic signature for certifying an origin is attached to the archive file.
