Accessing Oracle Discoverer 3i Viewer From Other Web Applications

Oracle Discoverer 3i Viewer can be accessed from other Web applications by specifying a combination of parameters in the URL. Rather than having your end users log in, choose a workbook, and worksheet, you can specify a URL that starts the Oracle Discoverer 3i Viewer for them. You can explicitly specify the settings that you want; for example, you can specify which workbook and worksheet you want to open and which parameter values to use.

This means you can embed live Discoverer reports directly onto your Web site pages simply by specifying the details in a URL. When the link is clicked the database is queried and the latest data is displayed in HTML.

After you create this URL, you can give it to end users to type into their Web browser. Or you can add the URL as a link on your company's Intranet site so that end users can make a specific database query with a single click.

In addition, you can also specify an end user's Applications Responsibility in this same URL.
