Question

我的项目中有一个奇怪的问题，比如我在webservice调用程序中收到错误

ERROR:  'DOM Level 3 Not implemented

在我的本地计算机上运行JAVA 1.6.0_45时。从我的项目中删除XALAN.jar。在其中一个课程中我已经取代了

import org.apache.xml.utils.QName;

用

import javax.xml.namespace.QName; //its from jaxrpc.jar

尝试应用转换时出现错误

TransformerFactory xf = TransformerFactory.newInstance();

        try {
            Document responseDocument = (Document) object.newDomNode(options);

            Transformer xformer = xf.newTransformer();
            xformer.setOutputProperty(OutputKeys.METHOD, "xml");
            xformer.setOutputProperty(OutputKeys.INDENT, "yes");
            xformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");

            StringWriter writer = new StringWriter();
            Result out = new StreamResult(writer);

            if (!xmlEscape) {
                ProcessingInstruction pi = responseDocument
                        .createProcessingInstruction(
                                Result.PI_DISABLE_OUTPUT_ESCAPING, "");
                responseDocument
                        .getDocumentElement()
                        .getParentNode()
                        .insertBefore(pi, responseDocument.getDocumentElement());
            }

            xformer.transform(new DOMSource(responseDocument), out);

            // remove the <![CDATA[ before returning the response
            return removeCdata(writer.getBuffer().toString());
        } catch (TransformerConfigurationException e) {
            throw new XMLSchemaException(
                    "Unable to generate request message due to " + e);
        } catch (IllegalArgumentException e) {
            throw new XMLSchemaException(
                    "Unable to generate request message due to " + e);
        } catch (TransformerException e) {
            throw new XMLSchemaException(
                    "Unable to generate request message due to " + e);
        }

错误发生在行

中

xformer.transform(new DOMSource(responseDocument), out);

任何帮助都将不胜感激。

编辑：此错误的主要原因是

TransformerFactory xf = TransformerFactory.newInstance();

返回weblogic.xml.jaxp.RegistrySAXTransformerFactory@16849e2a

的实例

而不是

com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl

作为JAVA 6中的transformerfactory的默认实例。

是否有一个临时修补程序通过将其转换为DOM3 compilant来解决此问题。而实际的解决方案是停止使用xecers，xbean。

Document responseDocument = (Document) object.newDomNode(options);
DocumentBuilder builder = DocumentBuilderFactory.newInstance()
                    .newDocumentBuilder();
            Document doc3 = builder.newDocument();
            Element newRoot = (Element) doc3.importNode(
                    responseDocument.getDocumentElement(), true);
            doc3.appendChild(newRoot);

和传递新doc3的转换方法

xformer.transform(new DOMSource(doc3), out);

获取错误DOM Level 3删除xalan.jar后未实现
