Introduction and Roadmap 1-5
1.6.5 JAXP Pluggability Layer Implementation
Java API for XML Processing JAXP 1.2 is a Java-standard, parser-independent API for XML. For more information on JAXP, see
Section 2.7, What Is JAXP?.
1.6.6 Java API for XML Registries Implementation
The Java API for XML Registries JAXR API, described at http:java.sun.comxmljaxrindex.jsp
, provides a uniform and standard Java API for accessing different kinds of registries, in particular XML registries used in
Web Service applications. For more information, see
Section 5.1, Using the Java API for XML Registries JAXR API.
1.6.7 WebLogic Servlet Attributes
WebLogic Server supports the following special Servlet attributes:
■
org.xml.sax.HandlerBase
■
org.xml.sax.helpers.DefaultHandler
■
org.w3c.dom.Document Calling the setAttribute for SAX parsing and getAttribute for DOM parsing
methods on a ServletRequest object with the preceding attributes will parse any given XML document.
For more information, see Section 3.2.3, Parsing XML Documents in a Servlet.
1.6.8 WebLogic XSLT JSP Tag Library
The JSP tag library provides a simple tag that enables access to the default XSLT transformer from within a Java Server Page JSP running on WebLogic Server.
Currently, this tag supports the default XSLT transformer only; you cannot use the tag to transform an XML document from within a JSP using a different transformer.
The JSP tag library is included in xmlx-tags.jar, which is installed when you install your WebLogic Server distribution.
For more information, see Section 3.4.3, Using the JSP Tag to Transform XML Data.
1.6.9 XML Registry For Configuring Parsers and Transformers
The XML Registry simplifies administration and configuration tasks by separating these tasks from the XML application. Use the Administration Console to configure
the parsers and transformers for an instance of WebLogic Server.
For more information, see Section 9.2, XML Parser and Transformer Configuration
Tasks.
Note: WebLogic Server uses the XML Registry, accessed through the
Administration Console, to plug in parsers and transformers. This is different from the JAXP 1.2 specification which specifies the use of
system properties to plug in parsers and transformers.
1-6 Programming XML for Oracle WebLogic Server
1.6.10 XML Registry for Configuring External Entity Resolution
WebLogic XML supports external entity resolution through the XML Registry. For more information, see
Section 9.3, External Entity Configuration Tasks.
1.7 Endorsed Standards Override Mechanism for DOMSAX: Not Supported
WebLogic Server does not support switching the servers DOM and SAX interfaces using the endorsed standards override mechanism.
An endorsed standard is a Java API defined through a standards process other than the Java Community Process JCP. For more information, see Endorsed Standards
Override Mechanism at http:java.sun.comjavase6docstechnotesguidesstandards
