[Yanel-dev] [FYI] SAXTransformerFactory#newTransformerHandler returning null

[Guillaume Déflache]

Hi!

When using XSLT via the JAXP API, you may use the 
SAXTransformerFactory#newTransformerHandler(Source) method 
(<http://java.sun.com/javase/6/docs/api/javax/xml/transform/sax/SAXTransformerFactory.html#newTransformerHandler(javax.xml.transform.Source)>).

Please be aware than with Xalan (2.7.1 at least) this method may only 
return null if your XSLT is incorrect for some reason (in our case this 
was a namespace used in XPath that never got declared), instead of 
complaining loudly, which can be extremly confusing.

HTH,
    Guillaume
