Oh, alright then. I guess that means that if I want to use the same XSLT to transform XML inside a servlet, I'll need to either create a new Transformer for every request, or synchronize a single transformer (or a combination approach with a pool of Transformers) right?

But what about xalan:evaluate()?

This works with the default transformer, but not with translets. Whenever I try to use a translet I get the error: 'Cannot find external method 'org.apache.xalan.lib.Extensions.evaluate' (must be public).' for xalan:evaluate(), and the error: 'The first argument to the non-static Java function 'evaluate' is not a valid object reference.' for dyn:evaluate(). Here are the XML and XSL files I wrote to test this: <?xml version='1.0' encoding='UTF-8'?> <TestElement> <data someAttribute="5"/> <data someAttribute="10"/> </TestElement> <xsl:stylesheet version = '1.0' xmlns:xsl='http://www.w3.org/1999/XSL/Transform' xmlns:xalan='http://xml.apache.org/xalan' xmlns:dyn="http://exslt.org/dynamic";> <xsl:template match="/"> <xsl:value-of select="xalan:evaluate('//TestElement/data[1]/@someAttribute')"/> <xsl:value-of select="dyn:evaluate('//TestElement/data[1]/@someAttribute')"/> </xsl:template> </xsl:stylesheet> For transforming without tranlets I used the SimpleTransform sample program that comes with xalan-j, and for tranlets I used JAXPTranletOneTransformation. I?m using J2SE 1.4.2 and J2EE 1.4 final, with the endorsed xalan jars. SimpleTransform works, JAXPTranletOneTransformation doesn?t, though it works if the evaluate() extension calls are taken out.
