Using Oracle XML Components to Generate XML Documents: Java

Figure 3-7 shows the Oracle XML Java components and how they can be used to generate an XML document. Available XML Java components are:

• XDK for Java:
  • XML Parser for Java, Version 2 including the XSLT

  • XML Class Generator

  • XSQL Servlet

  • XML Transviewer Beans

• XML-SQL Utility (XSU) for Java

In the Java environment, when a user or client or application sends a query (SQL), there are three possible ways of processing the query using the Oracle XML components:

A. By the XSL Servlet (this includes using XSU and XML Parser)

B. Directly by the XSU (this includes XML Parser)

C. Directly by JDBC which then accesses XML Parser

Regardless of which way the stored XML-ized data is generated from the database, the resulting XML document output from the XML Parser is further processed, depending on what you or your application needs it for.

The XML document is formatted and customized by applying stylesheets and processed by the XSLT.
