12/30/2023 0 Comments Oracle java sliding reports![]() These tags can be used as templates to enable you to build and insert your own data-driven Java component into a JSP-based Web report. Using the Oracle Reports custom JSP tags, you can easily add report blocks and graphs to existing JSP files. The entire report can now be defined using XML tags and saved as an XML file. When a report is saved as a JSP file, the data model is embedded using XML tags. The benefit of saving reports as JSPs is that JSPs are text files that are easy to edit as opposed to, for example, the binary. New reports are by default saved as JSP reports. You can create new JSP reports, or save existing reports as JSP reports. In Oracle Reports, you use JSPs to embed data retrieved using the data model into an existing Web page to create a JSP-based Web report. Oracle Reports supports JavaServer Pages (JSPs) as the underlying technology to enable you to enhance Web pages with information retrieved using Oracle Reports Builder. Because it is stored in memory, subsequent calls to that page are very fast, thereby avoiding the performance limitations seen with traditional Common Gateway Interface (CGI) programs, which spawn a new process for each HTTP request.įor additional background information about JSP technology, see the Sun Microsystems Java and Java EE Web site at. When a JSP is called for the first time, it is compiled into a Java servlet class and stored in the Web server's memory. Require less effort to install and maintain. Scale to a larger number of simultaneous users. Run on thinner clients, thereby consuming fewer client-machine resources. Run on a wider variety of client machines and browsers. Unlike traditional client-server applications, JSP applications: ![]() The JSP container interprets the JSP tags and scriptlets, compiles the JSP into a Java servlet and executes it, which generates the content required, and sends the results back to the browser as an HTML or XML page.Ī JSP can be accessed and run from a browser-based client, typically over the Internet or a corporate intranet. This extension notifies the Web server that the page should be processed by a JSP container. JSP-specific tags or Java-based scriptlets can be utilized to call other components that generate the dynamic content on the page. Because JSPs cleanly separate dynamic application logic from static HTML content, Web page designers who have limited or no Java programming expertise can modify the appearance of the JSP page without affecting the generation of its content, simply using HTML or XML tags to design and format the dynamically-generated Web page. JSPs keep static page presentation and dynamic content generation separate. The HTML provides the page layout that is returned to the Web browser, and Java provides the business logic. A JSP is an HTML page with embedded Java source code that is executed in the Web server or application server. JavaServer Pages (JSPs) technology is an extension to the Java servlet technology from Sun Microsystems that provides a simple programming vehicle for displaying dynamic content on a Web page. 2.2.1 About JavaServer Pages (JSPs) and servlets
