Abstract

An applet latest version automatically setting system automatically sets the latest version of an applet such as a Java applet, etc. at a request of a client. Specifically, it stores in a method of an applet a program to update a version, realizes the update of the version of an applet in a process of the applet itself, and can necessarily use an applet of the latest version.

Claims

1. An applet latest version automatically setting system, comprising:

a central office server of a banking institution having an applet storage unit storing an applet of a latest version and having a single-program structure, and a version number storage unit storing a version number of the applet stored in the applet storage unit; and

a branch office terminal unit of the banking institution having a version number information storage unit performing a process based on the applet read from said server, and storing a local version number of the applet, a comparison unit reading the version number of the applet of the latest version from the version number storage unit of the central office server when a predetermined event occurs, and comparing the read version number with the local version number stored in the version number information storage unit, and an update unit reading the applet of the latest version from the applet storage unit of the central office server and updating an applet at the branch office terminal unit when the comparison unit outputs a non-matching result,

wherein the predetermined event includes at least one of an initialization of the applet or a detection of a user event causing performance of an online process during execution after the applet is initialized, and

wherein the applet at the branch office terminal unit is deleted and the applet of the latest version is retrieved when the applet at the branch office terminal unit is terminated.

2. The system according to claim 1, wherein said applet is a processor-independent byte-code applet.

3. The system according to claim 2, wherein said predetermined event occurs when the applet becomes active.

4. The system according to claim 1, wherein distributed object computing infrastructure communications are established between said central office server and said branch office terminal unit.

5. The system according to claim 1, wherein said version number storage unit is a main memory or a disk unit.

6. A central office server of a banking institution, comprising:

an applet storage unit updating and persistently storing an applet of a latest version, the applet having a single-program structure; and

a version number storage unit storing a version number of the applet stored in said applet storage unit,

wherein the version number is read from said version number storage unit at a version number information read request, and is transmitted to a branch office terminal unit,

wherein the version number information read request is caused by at least one of an initialization of the applet or a detection of a user event causing performance of an online process during execution after the applet is initialized, and

wherein the applet at the branch office terminal unit is deleted and the applet of the latest version is retrieved when the applet at the branch office terminal unit is terminated.

7. The server according to claim 6, wherein said applet is a processor-independent byte-code applet.

8. A branch office terminal unit of a banking institution, comprising:

a version number information storage unit performing a process based on an applet having a single-program structure read from a central office server of a banking institution, and storing a local version number about the applet;

a comparison unit reading the version number of the applet of the latest version from the central office server when a predetermined event occurs, and comparing the read version number with the version number stored in said version number information storage unit; and

an update unit reading the applet of the latest version from said applet storage unit and updating the applet at the branch office terminal unit when the comparison unit outputs a non-matching result,

wherein the predetermined event includes at least one of an initialization of the applet or a detection of a user event causing performance of an online process during execution after the applet is initialized, and

wherein the applet at the branch office terminal unit is deleted and the applet of the latest version is retrieved when the applet at the branch office terminal unit is terminated.

9. The terminal unit according to claim 8, wherein said applet is a processor-independent byte-code applet.

10. The terminal unit according to claim 9, wherein said predetermined event occurs when the applet becomes active.

11. The terminal unit according to claim 9, wherein said version number information storage unit is a main memory or a disk unit.

12. The terminal unit according to claim 8, wherein said version number information storage unit is a main memory or a disk unit.

13. An applet latest version automatically setting method, comprising:

storing an applet of a latest version and having a single-program structure in an applet storage unit of a central office server;

storing a version number of the applet in a version number storage unit of the central office server;

storing the version number read from said version number storage unit in a version number information storage unit of a branch office terminal unit of the banking institution as a local version number;

reading the version number of the applet of the latest version from the version number storage unit of the central office server when a predetermined event occurs, and comparing the read version number with the local version number stored in the version number information storage unit; and

reading the applet of the latest version from the applet storage unit of the central office server when the comparison produces a non-matching result, and updating the applet on the terminal unit,

wherein the predetermined event includes at least one of an initialization of the applet or a detection of a user event causing performance of an online process during execution after the applet is initialized, and

wherein the applet at the branch office terminal unit is deleted and the applet of the latest version is retrieved when the applet at the branch office terminal unit is terminated.

14. The method according to claim 13, wherein said applet is a processor-independent byte-code applet.

15. A computer-readable storage medium storing a program used to direct a computer to perform:

storing an applet of a latest version and having a single-program structure in an applet storage unit of a central office server of a banking institution;

storing a version number of the applet in a version number storage unit of the central office server;

storing the version number read from said version number storage unit in a version number information storage unit of a branch office terminal unit of the banking institution as a local version number;

reading the version number of the applet of the latest version from the version number storage unit of the central office server when a predetermined event occurs, and comparing the read version number with the local version number stored in the version number information storage unit; and

reading the applet of the latest version from the applet storage unit of the central office server when the comparison produces a non-matching result, and updating the applet on the terminal unit,

wherein the predetermined event includes an initialization of the applet and a detection of a user event causing performance of an online process during execution after the applet is initialized, and

wherein the applet at the branch office terminal unit is deleted and the applet of the latest version is retrieved when the applet at the branch office terminal unit is terminated.

16. An applet latest version automatically setting system, comprising:
