Hi Folks Related to my serializer question - but different enough for its own post. By the way, what do people recommend for a serializer. I use the trax type code of: TransformerFactory transFact = this.getTransformerFactory(); SAXTransformerFactory saxTFactory = (SAXTransformerFactory) transFact; m_tranHandler = saxTFactory.newTransformerHandler(); m_transformer = m_tranHandler.getTransformer(); However for getTransformerFactory() // TransformerFactory transFact = new net.sf.saxon.TransformerFactoryImpl(); // TransformerFactory transFact = new TransformerFactoryImpl(); // gets the JDK built in one - newInstance did not work. //TransformerFactory transFact = TransformerFactory.newInstance(); // TransformerFactory transFact = TransformerFactory.newInstance("net.sf.saxon.TransformerFactoryImpl",null); TransformerFactory transFact = new com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl(); I can only get the built in xalan factory working well - might be some other requirements I have - but curious what people are doing there. I really don't like reaching into the jdk like that as it is not supported Also, is there a way on the serializer to turn off DTD defaulted values without wrapping the serializer and using the Attributes.isSpecified?
