Upgrading WebLogic Server 4.5 and 5.1 to Version 7.0
2-36
BEA WebLogic Server 7.0 Upgrade Guide
XML 7.0 Parser and Transformer
The built-in parser and transformer in WebLogic Server 7.0 have been updated to 
Xerces 1.4.4 and Xalan 2.2, respectively. If you used the APIs that correspond to older 
parsers and transformers that were shipped in previous versions of WebLogic Server, 
and if you used classes, interfaces, or methods that have been deprecated, you might 
receive deprecation messages in your applications .
WebLogic Server 7.0 also includes the WebLogic FastParser, a high-performance 
XML parser specifically designed for processing small to medium size documents, 
such as SOAP and WSDL files associated with WebLogic Web services. Configure 
WebLogic Server to use FastParser if your application handles mostly small to 
medium size (up to 10,000 elements) XML documents.
The WebLogic Server 7.0 distribution no longer includes the unmodified Xerces 
parser and Xalan transformer in the 
WL_HOME\server\ext\xmlx.zip
 file.
