The process of easily publishing with eXtensible Markup Language (XML) through an enterprise portal that provides one interface to aggregated and componentized information is described. Enterprise portals can substantially streamline navigation with Web sites and ease publishing of information from many sources. Portlets, which are the basic building blocks of enterprise portlets, are reusable, personalized Web components that show content from various data sources. Topics covered include leveraging of extant XML feeds and rendering directly into the enterprise portal, access to XML and Web services feeds, access to protected universal resource locators (URLs), caching portlets, supporting filtering and layout formatting, and access to XML through Java using the Portal Standard JSR 168. When there is a requirement to extend functionality to allow developers to have more control over integration with the application or Web services, developers can either extend the portlet already created by the wizard-based tool or program the portlet from the outside and have complete control over the application. The extension of the portlet created by the wizard-based tool is a more productive solution. Java Specification Request (JSR) can be used to program portlets and is a specification that defines a set of APIs to enable interoperability between portlets and portals, addressing the areas of aggregation, personalization, presentation, and security. When hyperlinks need to be more dynamic than with Hypertext Markup Language (HTML), enterprise portals raise interactivity and reusability to a higher level.
