Ola ;
Tenho uma aplicacao que consome WebService com JAX-RPC.

Preciso fazer uma COMPARACAO de XMLs onde uso APACHE XERCES 2.11

Quando incluo a Biblioteca do Xerces no meu ClassPath dá o seguinte erro :

Alguem pode me ajudar ? Obrigado

NÃO HÁ maneira de JAX-RPC e APACHE XERCES conviverem no mesmo sistema.

A solução foi converter a classe que usava o parser XMLREADER para JAX-RPC - SAXParserFactory

O código anterior era este :

private static final String	_PARSER_NAME = "org.apache.xerces.parsers.SAXParser";
        //private static final String	_PARSER_NAME ="javax.xml.parsers.SAXParser"; //esta tentativa nao funcionou

			_parser = (XMLReader)Class.forName(_PARSER_NAME).newInstance();
			_parser.setFeature("http://xml.org/sax/features/validation", _setValidation);
			_parser.setFeature("http://xml.org/sax/features/namespaces", _setNameSpaces);
			_parser.setFeature("http://apache.org/xml/features/validation/schema", _setSchemaSupport);
			_parser.setFeature("http://apache.org/xml/features/validation/schema-full-checking", _setSchemaFullSupport);
 			_parser.setFeature("http://xml.org/sax/features/namespace-prefixes", _setNameSpacePrefixes);

			_parser.setContentHandler(this);
			_parser.setErrorHandler(this);
			_parser.setProperty("http://xml.org/sax/properties/lexical-handler", this);

O cógigo convertido para SAXParserFactory ficou :

private static final String	_PARSER_NAME = "org.apache.xerces.parsers.SAXParser";
        //private static final String	_PARSER_NAME ="javax.xml.parsers.SAXParser"; //esta tentativa nao funcionou

			//_parser = (XMLReader)Class.forName(_PARSER_NAME).newInstance();
                        _spf = SAXParserFactory.newInstance();
			_spf.setFeature("http://xml.org/sax/features/validation", _setValidation);
			_spf.setFeature("http://xml.org/sax/features/namespaces", _setNameSpaces);
			_spf.setFeature("http://apache.org/xml/features/validation/schema", _setSchemaSupport);
			_spf.setFeature("http://apache.org/xml/features/validation/schema-full-checking", _setSchemaFullSupport);
 			_spf.setFeature("http://xml.org/sax/features/namespace-prefixes", _setNameSpacePrefixes);

                        _parser = _spf.newSAXParser();

			//_parser.setContentHandler(this);
			//_parser.setErrorHandler(this);
			_parser.setProperty("http://xml.org/sax/properties/lexical-handler", this);
