Use Web clipping to import content


Overview

Create Web clipping portlets to identify and extract specific portions of a document for display in a portlet.

Many Web sites and browser-based applications are designed for desktop displays that support large windows and complicated layout. Depending on the amount and complexity of the content, it can be impractical to include the content in a portlet. If your users also expect to access the portlet from a mobile device, such as a phone or PDA, the ability to tailor content to these small displays is increasingly important.

You can create Web clipping portlets to identify and extract specific portions of a document for display in a portlet. In this way, you can keep those pieces of information that are important, while discarding undesirable information or elements in the document that the client device is incapable of displaying. The Web clipping process simplifies what is being sent to the device, while reducing the amount of data being transmitted - a particularly useful aspect when wireless devices are involved.

  1. Create a Web clipping portlet

    To help you perform Web clipping on sites that you want to include in your portlets, WebSphere Portal enables you to create Web clipping portlets to specify how you want to tailor the content of particular documents.

    To create a Web clipping portlet, select...

    Administration tab | Portlet Management | Web clipping

  2. Configure URL rewriting

    Configure the URL rewriting options of your Web Clipping portlet so that when a user follows a link in the Web clipping portlet, the content retrieved by the link is either displayed inline within the portlet window (default), in the same browser window, or in a new browser window.

  3. Access content behind a firewall

    To create clipping portlets that can access content behind firewalls, configure the firewall options for a Web clipping portlet using the Modify firewall options page when you create a Web clipping portlet, or you can add these options later.

  4. Specify client cookie support

    Configure your Web clipping portlet to propagate specific cookies from client-side through the portal to the origin server.

  5. Change restart settings

    Web clipping portlets support an inter-portlet communication mechanism that allows clipping portlets on the same page as a given Web portlet to "restart."

  6. Specify caching timeout

    If the display cache is enabled for the portal, and if a CacheTimeout configuration parameter is set for a particular Web clipping portlet, the Web clipping portlet will have its output cached for the time period of seconds specified by the value of CacheTimeout.

  7. Specify connection time out

    The read timeout parameter is an integer representing the timeout value in milliseconds.

  8. Specify mobility options

    You can disable a Web Clipping portlet when accessed from a mobile device by enabling the option...

    Do Nothing option

    ...on the Modify Mobility Options page.

  9. Specify authentication options

    Web Clipping portlets support accessing content that requires either...

    • HTTP Basic authentication
    • FORM-based authentication
    • Integrated Windows Authentication (NTLM)

    The default setting for authentication options is...

    No authentication required
