Abstract

By merely performing simple operations, an operating environment for an application program is prepared and the application program started. An applet capable of being distributed easily on an internet is used as a bootstrap to start an application program which is adapted to operate directly on the OS on which an associated browser is operating. In one aspect of this invention, the applet not only merely downloads code of an application program but also judges whether the application program code is cached or not in a local file system, checks the execution environment, checks for prerequisite software, and checks the version thereof. If the application program code is cached in the local file system, the application program is not downloaded. If any prerequisite software is not present, the prerequisite software is downloaded and the application program is started.

Claims

1. A method for starting an application program loaded from a server on a client machine, comprising the steps of:

(a) loading an execution environment identifying applet from the server in response to an application program starting request made on the client machine;

(b) loading, from the server, a code that the application program to be started on the client machine requires and a starting command for starting the application program, on the basis of a result obtained by of executing the execution environment identifying applet; and

(c) executing the starting command on the client machine and starting the application program.

2. A method for starting an application program loaded from a server on a client machine, comprising the steps of:

(a) loading, from the server, a code that the application program to be started on the client machine requires and a starting command for starting the application program, in response to an application program starting request made on the client machine; and

(b) executing the starting command on the client machine and starting the application program.

3. The method according to

claim 2

,

further comprising the step of judging whether the code which the application program requires is present or not on the client machine,

wherein, with respect to the code which the application program requires and the starting command for starting the application program, the code which the application program requires is loaded from the server when the code which the application program requires is not present on the client machine.

4. A software product for starting an application program loaded from a server on a client machine, comprising:

(a) an execution environment identifying software for identifying an execution environment from the server in response to an application program starting request made on the client machine;

(b) a required code acquiring software for acquiring a code which the application program to be started on the client machine requires; and

(c) an application program starting software for executing a starting command for starting the application program on the client machine and thereby starting the application program.

5. A software product for starting an application program loaded from a server on a client machine, comprising:

(a) a required code acquiring software for loading from the server a code which the application program to be started on the client machine requires and a starting command for starting the application program, in response to an application program starting request made on the client machine; and

(b) an application program starting software for executing the starting command on the client machine and starting the application program.

6. The software product according to

claim 5

, wherein the required code acquiring software has a function of judging whether the code which the application program requires is present or not on the client machine.
