14.7 About Incorporating Content from Other Web Sites

Typically, pages in an application are based on data stored in an Oracle database. To incorporate content from other servers, you can create a region based on a URL to display content. For example, suppose you wanted to reference the current Oracle stock price. You could create a region of type URL based on a URL. For example:

http://quote.yahoo.com/q?d=b&s=ORCL

You could then create an item called STOCK_SYMBOL and base your region on a stock price entered by the user. For example:

http://quote.yahoo.com/q?d=b&s=&STOCK_SYMBOL.

Sometimes (as is the case with the previous example) the HTML returned to the region is more than is needed. To restrict the HTML displayed, you can use the following region attributes:


Tip:

The previous example may require that you set the Proxy Server application attribute. If you do not set the Proxy Server application attribute, you get an error message. Oracle Application Express uses the Oracle utl_http.request_pieces function to obtain the HTML generated from the given URL. See "Editing the Application Attributes."

Developers can also use the Region attribute Inclusion Mode to control how Oracle Application Express retrieves and displays the content. Options include:

Working with SSL-Enabled URLs

If you call a SSL-enabled URL (for example, by invoking a Web service), or create a region of type URL that is SSL-enabled, you must create a wallet. A wallet is a password-protected container that stores authentication and signing credentials (including private keys, certificates, and trusted certificates) needed by SSL.
