About HtmlViewService Bridging and Callback URLs

To embed a report with active drilldown links, the HtmlViewService service allows the Web browser to issue callback requests from embedded reports to the Oracle BI Web Services server. Although it is possible to route requests directly to the Oracle BI Web Services server, in many cases it is preferable to route requests through the Presentation Services that originally serviced the third-party page. Also, in situations where Oracle BI Web Services and the third-party Web server do not belong to the same Domain Name Service (DNS) domain, users may get JavaScript errors related to browser security constraints for cross-domain scripting.

To avoid these issues, use the setBridge() method to modify callback URLs to point to the third-party Web server. Be aware that a Web component executed by the third-party Web server to re-route requests to Oracle BI Web Services is not provided. This function would need to be fulfilled by the third-party application. For more information about the setBridge() method, read setBridge() Method.
