ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates in general to programming development environments performed by computers, and in particular, to a method and apparatus for remotely scripting local objects in a network server.
2. Description of Related Art
With the fast growing popularity of the Internet and Intranets, especially Web-based networks, there is also a fast growing demand for Internet and Intranet access to databases. Web-based networks operate using the HyperText Transfer Protocol (HTTP) and the HyperText Markup Language (HTML). HTTP is the protocol used by Web clients and Web servers to communicate between themselves using these hyperlinks. HTML is the language used by Web servers to create and connect together documents that contain these hyperlinks. This protocol and language results in the communication and display of graphical information that incorporates hyperlinks. Hyperlinks are network addresses that are embedded in a word, phrase, icon or picture that are activated when the user selects a highlighted item displayed in the graphical information.
The Internet has considerable potential to provide access to powerful and complex applications implemented at the Web server to a broad scope of remote clients. This implementation has important benefits such as reducing computer memory and processing requirements at the remote client, and increasing the security of the application by retaining selected portions of the application in a secure location in the Web server. However, such implemetations can be communication intensive, and communication bandwidth and latency is already a problem, even for simple Internet applications. What is needed is a method of implementing Internet applications that provides the application developer the flexibility to allocate functional capability between the remote client and the Web server so as to meet the security, remote client processing and communication link requirements for the particular application. The present invention satisfies that need.
SUMMARY OF THE INVENTION
To overcome the limitations in the prior art described above, and to overcome other limitations that will become apparent upon reading and understanding the present specification, the present invention discloses a method, apparatus, and article of manufacture for remotely scripting local objects.
The method comprises the steps of executing an applet in a browser in a remote client computer, thereby generating control information, transmitting the control information to the Web server to initiate execution of a script in the Web server and generate output data therefrom, and transmitting the script output from the network server to the browser. This output data can be thereafter used to execute another applet in the client browser. The output data need not comprise an entire HTML page, but may comprise only a portion of the page as required to display the required information.
The invention also comprises an apparatus for remotely scripting local objects. The apparatus includes a client computer for executing an applet in a browser to generate control information and a network server communicatively coupled to the client computer. The network server comprises a means for executing a script therein in accordance with the control information to generate script output data and a means for transmitting the script output data to the client computer.
