【文章內(nèi)容簡介】 fields in the label storehouse. Can expand and increase the function of JSP unrestrictedly like this, and does not need to wait for the appearance of the next edition JSP . Systematic position and realizing： (1) The system making up This system is made up of four parts mainly： The database joins some: This system supports several daily databases , including Oracle, Sybase, MSSQLServer, MySQL and DB2, use JDBC and database to link to each other according to database type and database name , user name , password that users offer that users choose. The basic form of system produces some: After joining with the database , produce the basic form TCTables and TCColumns of two systems according to the user name linking to each other with the database , TCTables form includes English name , Chinese name and some attribute of form belonging to this user in this database , for instance can revise , can inquire about 。 The Chinese and English name of the row and some other attribute that TCColumns form includes belonging to all forms of this user39。s in this database . For instance can show , can inquire about . Basic information of the database that these basic forms of two systems provide to user39。s institute for use in the course of development of the whole system. The template is chosen to produce some with the webpage: This part is a key part of a system. It includes two pieces of sub module . ① The template is chosen some: The system offers the template to user and chooses the interface, let users choose the templates used from the template storehouse according to the need. ② The template is dealt with some: According to template that user choose, system transfer designated template deal with module is it punish to go on to these template. When dealing with the label that the procedure meets in the template, offer the mutual interface to user, let user input parameter for designated label , prove system validity of label that user input. Finished the formulation of JSP page systematically finally. Webpage preview is with revising some: After the webpage was produced out, the system has offered a webpage preview window and code to user and looked over that revises the window. Through this preview window, users can look at the result of JSP page produced out in advance . If user static result of respect in page very satisfied, user can through code look over revise window revise HTML code of code. If users have further demands for the static result of the page, the system has also offered a piece of interface which transfers DreamWeaver editing machine to user, users can use it to carry on further modification and perfection to the static result of JSP page that is produced out . (2) Systematic realization Realization of the template storehouse and label storehouse The planning and design of the label storehouse are essential in the whole system design, efficiency that the degree and system that are put in an position have operated that its relation has reached codes. Its planning should follow the following principle . (1) Should try one39。s best little including static HTML among label. To general user, the label is transparent. Users can not look over and revise labels . If include too many static HTML sentence in the label , will influence the modification and perfection of user39。s static result to the page, limit the use of the label. (2) Try one39。s best to raise the paying most attention to degree of the code. Is it is it is it is it is it is it get to JSP public JSP out to withdraw to use to try one39。s best to classify to go on to use, form labels. Do not use and realize this application repeatedly in each label . While revising and perfecting to using like this , only need to revise this label, maintenance of the easy code. (3) Facilitate users39。 use. While designing the label storehouse , should fully consider users39。 operating position , it can very easy and understanding and using labels conveniently to use the family. ① Definition of the label storehouse: Define a label storehouse, must define a label storehouse and describe the file (TLD ) at first . This is a file of script based on XML, have defined the edit
