Class OrdURLBuilder

java.lang.Object
  |
  +--oracle.ord.html.OrdURLBuilder

public class OrdURLBuilder

extends java.lang.Object

Generates an URL string that retrieves the media content referenced by the interMedia Business Component for Java (BC4J) domain objects.

The URL string can be used as the value for the HTML IMAGE(<IMG>) tag's SRC attribute or in HTML ANCHOR(<A>) tag's HREF attribute. Users can also use the URL string to construct HTML EMBED(<EMBED>) or OBJECT(<OBJECT>) tags to render multimedia content in the browser.

This class is used by OrdBuildURLRenderer class and interMedia BC4J Data Tags, such as <jbo:MediaUrl>, to generate the media fetching URL.

The [mediaFetchingURL] has the following format:

[retrievepath]?appModId=[appModId]&rowSetName=[rowSetName]& contentCol=[mediaAttributeName]&rowKey=[rowKeyString]

By default, the [retrievepath] is a pre-supplied JSP page called ordPlayMedia.jsp. Users are allowed to provide their own custom retrieve path.

By using this utility class, users can write their own HTML display renderer class to create customized HTML tag strings for the interMedia domain classes.

Since:

JDev5.0
