Question

尝试在JBOSS 4.0.3中部署JAX-WS Web服务时，我遇到了以下错误。我正在使用JAX-WS RI运行时库。我没有使用JBOSS-WS JBOSS特定的JAX-WS。

在web.xml中，我为该课程设置了听众：com.sun.xml.ws.transport.http.servlet.WSServletContextListener

类javax.xml.transform.TransformerFactory是抽象的，您需要在类路径中的某个位置实现该类。异常java.lang.AbstractMethodError: javax.xml.transform.TransformerFactory.setFeature(Ljava/lang/String;Z)通常表示依赖项中存在版本冲突，因为您使用的实现是针对不同版本的接口构建的。

要解决此问题，您必须使用匹配的实现。 TransformerFactory实现包含XML解析器，如Xalan或Xerces。您可以通过设置适当的系统属性来告诉Java使用某个解析器实现：

    Properties p = System.getProperties();
    p.setProperty("javax.xml.transform.TransformerFactory", "com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl");
    p.setProperty("javax.xml.parsers.DocumentBuilderFactory", "com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl");
    p.setProperty("javax.xml.parsers.SAXParserFactory", "com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl");
    System.setProperties(p);

在应用程序初始化期间执行此操作会将默认解析器实现设置为JRE的内部Xalan解析器。要使用其他解析器，请包含它们的依赖项，并将实现类的名称放在setProperties方法中。
