Abstract

It is demanded to add a new service to the Web quickly and to develop a Web application system in a short period of time to extend a service. It is thus necessary to alleviate the burden on developers or programmers to speed up development, and to cope with complicated systems or to make systems extensible. Thus, the system has to be designed to clearly associate components with one another and separate their respective roles. In the development of a Web application system, each of the components of the servlet, JSP, and Bean is defined in a one-to-one relationship corresponding to each screen image, thereby making the relationship among each of the components clear. A component table generating unit is provided for generating the definition of each component as a component table from screen design. Also provided is an automatic code generating unit for automatically generating the code of servlet, JSP, and Bean using the component table and the information of the design document. This facilitates the development and alleviates the burden on developers or programmers.

Claims

1. A Web application development method for developing, on the Inter- and Intranet, a Web application system having server-side Java technologies such as a servlet, JSP, and JavaBeans component (Bean), wherein

in accordance with a GUI specification provided by a design specification for said Web application system, a source filename of each component of the servlet, JSP, and Bean is defined corresponding to each screen image to develop the servlet, JSP, and Bean.

3. A method for developing a Web application according to

claim 1

or

2

, wherein

a source code of each component is automatically generated using the relationship between said screen and a source filename of each component of said servlet, JSP, and Bean, and information of said design specification.

4. A method for developing a Web application according to

claim 1

or

2

, wherein

said Bean component is provided with all pieces of information necessary for displaying an HTML page, and serves to carry out mapping information of an HTML page and information to be retrieved from a database.

5. A method for developing a Web application according to

claim 3

, wherein

upon generation of the source code of each component of said servlet, JSP, and Bean,

a template list is displayed for each component to be generated,

a template selected from the template list is employed as a model, and a code is written to the model in accordance with said design specification to automatically generate a source code.

9. A method for developing a Web application according to any one of

claims 1

to

8

, wherein

in a Web application system to be developed, the servlet serves to receive a request from a Web browser;

the Bean serves to perform processing in accordance with the request of the servlet to hold resulting data; and

the JSP serves to retrieve the resulting data of the Bean to generate an HTML displayed on the Web browser;

thus each role of the servlet, JSP, and Bean being separated from each other.

10. A program provided by a method for developing a Web application according to any one of

claims 1

to

9

.

11. A storage medium for storing a program provided by a method for developing a Web application according to any one of

claims 1

to

9

.

2. A Web application development method for developing, on the Inter- and Intranet, a Web application system having server-side Java technologies such as a servlet, JSP, and JavaBeans component (Bean), wherein

in accordance with a GUI specification provided by a design specification for said Web application system, a source filename of each component of the servlet, JSP, and Bean is defined in a one-to-one relationship corresponding to each screen image to develop the servlet, JSP, and Bean.

6. A Web application development method for developing, on the Inter- and Intranet, a Web application system having server-side Java technologies such as a servlet, JSP, and JavaBeans component (Bean), comprising the steps of:

reading a GUI specification provided by a design specification to generate each component name of a servlet, JSP, and/or Bean corresponding to a screen name for each screen,

selecting a template from a template list with respect to each component of a generated name, the template being a model of a source file of the component, and

generating automatically a source code of the component by writing the code to said template in accordance with a design specification of the component.

7. A method for developing a Web application according to

claim 6

, wherein

said template list includes a superclass template, and the step of generating automatically said source code is to inherit said superclass to create said source code.

8. A method for developing a Web application according to

claim 6

, wherein

said step of generating a name of each component is to generate a name of each component of a servlet, JSP, and/or Bean in a one-to-one relationship with a screen name for said each screen.

12. A Web application development system for developing, on the Inter- and Intranet, a Web application system having server-side Java technologies such as a servlet, JSP, and JavaBeans component (Bean),

said system comprising means for developing the servlet, JSP, and Bean by defining a source filename of each component of the servlet, JSP, and Bean corresponding to each screen image, in accordance with a GUI specification provided by a design specification for said Web application system.

14. A system for developing a Web application according to

claim 12

or

13

, further comprising

means for automatically generating a source code of each component, using the relationship between said screen and a source filename of each component of said servlet, JSP, and Bean, and information of said design specification.

15. A system for developing a Web application according to

claim 12

or

13

, wherein

said Bean component is provided with all pieces of information necessary for displaying an HTML page, and serves to carry out mapping information of an HTML page and information to be retrieved from a database.

16. A system for developing a Web application according to

claim 14

, further comprising

upon generation of the source code of each component of said servlet, JSP, and Bean,

means for displaying a template list for each component to be generated, for employing a template selected from the template list as a model, and for writing a code to the model in accordance with said design specification to automatically generate a source code.

20. A system for developing a Web application according to any one of

claims 12

to

19

, wherein

in a Web application system to be developed, the servlet serves to receive a request from a Web browser;

the Bean serves to perform processing in accordance with the request of the servlet to hold resulting data; and

the JSP serves to retrieve the resulting data of the Bean to generate an HTML displayed on the Web browser;

thus each role of the servlet, JSP, and Bean being separated from each other.

13. A Web application development system for developing, on the Inter- and Intranet, a Web application system having server-side Java technologies such as a servlet, JSP, and JavaBeans component (Bean),

said system comprising means for developing the servlet, JSP, and Bean by defining a source filename of each component of the servlet, JSP, and Bean in a one-to-one relationship corresponding to each screen image, in accordance with a GUI specification provided by a design specification for said Web application system.

17. A Web application development system for developing, on the Inter- and Intranet, a Web application system having server-side Java technologies such as a servlet, JSP, and JavaBeans component (Bean), comprising
