Why am I getting a “Namespace not supported by SAXParser exception?
We have seen this probem arise for two quite different reasons: • SAX1 interfaces are on your classpath in front of the SAX2 interfaces provided with your XML parser. or • The parser you are using to process a stylesheet Source and generate a Transformer does not have the namespaceAware property set to true. SAX1 on the classpath SAX1 should not be on your classpath. The SAX1 interfaces and implementations of the SAX1 SAXPparser are not namespace aware. To help diagnose your classpath, you can use the EnvironmentCheck utility. If you are running under JDK 1.3, see Issues running Xalan-Java on JDK 1.3. If you are running a servlet, make sure the servlet engine is not placing SAX1 on the classpath. Setting the parser to be namespace aware When you create a Transformer, you must use a namespace-aware parser to parse the stylesheet. If you use a TransformerFactory to process a stylesheet Source and generate a Transformer, the TransformerFactory instructs the SAXParserFactory to set the par
