Specify it on command line when you run java, or put it in a property file and make sure load it into your jvm:     * -Dorg.xml.sax.driver=org.apache.xerces.parsers.SAXParser if you're use xerces.       Alternatives: -Djavax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl -Djavax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl     * -Dorg.xml.sax.driver=org.apache.crimson.parser.XMLReaderImpl if you're use crimson.     * Make sure xerces.jar or crimson.jar or something similar on your classpath BTW, you can specify Transformer too the same fashion.     * javax.xml.transform.TransformerFactory = org.apache.xalan.processor.TransformerFactoryImpl if you're using xalan     * javax.xml.transform.TransformerFactory = com.icl.saxon.TransformerFactoryImpl if you're using saxon     * Make sure xalan.jar or saxon.jar or something similar on your classpath
