About the Presentation Layer
In Liquid Data, a presentation layer is the software component that handles the layout, formatting, and display of query results to users. Liquid Data provides a JSP (Java Server Pages) tag library that you can use to create the presentation layer in JSP pages. The Liquid Data tag library can be used with both stored queries and ad hoc queries. For more information about the Liquid Data tag library, see About the Liquid Data Tag Library in "Invoking Queries in JSP Clients" in Invoking Queries Programmatically.
Tasks for Creating the Presentation Layer
To create the presentation layer, complete the following steps in your JSP page:
In this step, you specify the URI of the Liquid Data tag library in the JSP page.
In this step, if the JSP client is deployed on a server other than the Liquid Data Server, you connect to the Liquid Data Server using BEA's t3 protocol.
In this step, you specify query parameters, if applicable.
In this step, you execute the query on the Liquid Data Server.
In this step, you process the results of the query by performing an XSL transformation using an embedded tag, such as the x:transform tag described in the JavaServer Pages Standard Tag Library 1.0 Specification, which is published by the Sun Microsystems, Inc. at the following URL:
