Oracle Forms Services – Secure Web.Show_Document() calls to Oracle Reports Server 6i

Using the Oracle Forms Web.Show_Document() Built-in to call Oracle Reports on the Web is an alternative to the Run_Report_Object() Built-in. The Web.Show_Document() Built-in accesses Web resources by issuing a HTTP“GET” request from the browser URL. HTTP “GET” requests, in contrast to“POST” requests, show the complete URL string with all the request parameters in the browser’s address bar, including those parameters that are considered sensitive information, such as log on information. This White paper shows you how to secure calls to Oracle Reports Services, issued by Forms using the Web.Show_Document() Built-in, by eliminating the need to expose the sensitive user id information in the Reports request URL. The solution described in this document is based on a Java Bean that resides on the Oracle Forms Web client and works with the Forms 6i and Reports 6icomponents of Oracle9i Application Server Release 1. SOLUTION FOR ORACLE REPORTS SERVER 6I Oracle9i Reports Services in Oracle9i Application Server9.0.2 and above handle authentication cookies differently than Reports Server 6i. The differences are within the format of the cookie, the number of cookies set and the way cookie expiration is defined. Securing Forms Web.Show_Document() calls to Oracle9i Reports, using Oracle9i Application Server Reports Services and Oracle Application Server 10g Reports Services, is the subject of separate Whitepaper available on http:/ / otn.oracle.com/products/ forms. Please make sure you download and implement the Oracle9i Reports version of this document when upgrading Forms 6i applications to Oracle9i Forms and beyond, or when accessing Oracle9iAS Reports Services with Forms 6i. USING WEB.SHOWBDOCUMENT BUILT-IN TO CALL REPORTS This section briefly covers the use of the Forms Web.Show_Document() Built-into call Oracle Reports on the Web. The Forms Web.Show_Document() Built-In requires two arguments passed within the call Web.Show_Document(URL, Target); URL – The URL is passed as a string in a variable, or as a combination of both. If the target Web page is located on the same server that runs Forms Services,relative addressing could be used. Target – Definition of the target where the addressed Web page should be displayed. Values must be single-quoted. Possible target values are ‘_blank’ to show the Reports output in an extra browser window, ‘_self’ to replace the Forms application with the Reports output, ‘

’ to load the Reports output into a named frame of the multi frame HTML page.
