Re: Pools of SAXTransformerFactory and TransformerHandler.

[Morris Kwan]

Take a look at the SAX2SAX sample. It is under the samples\SAX2SAX
directory of your Xalan distribution.

You can use a ThreadLocal variable to cache SAXTransformerFactory and
TransformerHandler. You can also reuse the XMLReader by using the
org.apache.xml.utils.XMLReaderManager class.

Hello,

I have a Java application that performs XSLT transformations. This
application
uses:
             - SAX events to feed the XSLT engine,
             - TrAX
             - and Xalan.

In addition to a cache of Templates I would like to pool
SAXTransformerFactory
and TransformerHandler instances in order to avoid their
creation/destruction,
and thus improve performances.

Do you think it's possible in a multithreaded application (Web application
-
Servlet)? If it is, how to?

Thank you in advance for your collaboration.
