Re: Java 1.4 SLOW

[Scott Nichol <sn...@scottnichol.com>]

Remember that 1.4 includes a copy of Crimson.  If you have been using 
a parser that is much faster, that could be the difference.  You can 
choose the parser that gets used by specifying the 
DocumentBuilderFactory.  Sun's docs for 
DocumentBuilderFactory#newInstance state

>>>>
Obtain a new instance of a DocumentBuilderFactory. This static method 
creates a new factory instance. This method uses the following 
ordered lookup procedure to determine the DocumentBuilderFactory 
implementation class to load: 

Use the javax.xml.parsers.DocumentBuilderFactory system property. 

Use the properties file "lib/jaxp.properties" in the JRE directory. 
This configuration file is in standard java.util.Properties format 
and contains the fully qualified name of the implementation class 
with the key being the system property defined above. 

Use the Services API (as detailed in the JAR specification), if 
available, to determine the classname. The Services API will look for 
a classname in the file META-
INF/services/javax.xml.parsers.DocumentBuilderFactory in jars 
available to the runtime. 

Platform default DocumentBuilderFactory instance. 
<<<<

On the server, you can specify the parser in web.xml with a parameter 
named XMLParser, the value of which is the class of the 
DocumentBuilderFactory.
