服务器端解析XML

<%@ page contentType="text/html; charset=gb2312"%>
<%@ page import="org.w3c.dom.*" %>
<%@ page import="javax.xml.parsers.*"%>
<%@ page import="java.io.*"%>
<%@ page import="javax.xml.transform.*"%>
<%@ page import="javax.xml.transform.stream.*"%>
<%
StringReader reader=new StringReader("ZCML.xml");
StreamSource xml = new StreamSource(reader);

String path = application.getRealPath("/xtsd/zcml/xml/XmlRes");
System.out.println(path);
StreamSource xsl = new StreamSource(path+"/XMLSelTree.xsl");
StreamResult result = new StreamResult(out);
TransformerFactory tFactory = TransformerFactory.newInstance();
Templates templates = tFactory.newTemplates(xsl);
Transformer trans = templates.newTransformer();
trans.setOutputProperty(OutputKeys.ENCODING,"GB2312");
trans.setOutputProperty(OutputKeys.METHOD,"html");
trans.setOutputProperty(OutputKeys.VERSION,"4.0");
trans.transform(xml, result);

%>

抛出一个 org.apache.jasper.JasperException: The output format must have a '{http://xml.apache.org/xalan}content-handler' property!

客户端解析是好的。。这个是什么异常，谢谢各位！

用断点调试看出在哪行，另外我xslt如下
public class XmlTools {
private DocumentBuilder db;
private DocumentBuilder db2;
private TransformerFactory tf;
private Transformer transformer;
private DOMSource domSource;
private DOMSource domSource2;
private DOMResult domResult;
private StreamResult streamResult;

public XmlTools() throws Exception {
dbf = DocumentBuilderFactory.newInstance();
db = dbf.newDocumentBuilder();
dbf.setNamespaceAware(true);
db2 = dbf.newDocumentBuilder();
dbf.setNamespaceAware(false);

tf = TransformerFactory.newInstance();
transformer = tf.newTransformer();

transformer.setOutputProperty("encoding", "gb2312");

domSource = new DOMSource();
domSource2 = new DOMSource();
domResult = new DOMResult();
streamResult = new StreamResult();
}

public Document transform(Document xmlDoc, Document xslDoc) {
if (xmlDoc == null || xslDoc == null) {
return null;
}
Document resultDoc = null;
try {
domSource2.setNode(xslDoc);
Transformer transformer = tf.newTransformer(domSource2);

domSource.setNode(xmlDoc);
domResult.setNode(null);
transformer.transform(domSource, domResult);
resultDoc = (Document) domResult.getNode();
} catch (Exception e) {
e.printStackTrace();
resultDoc = null;
}
return resultDoc;
}
}

可将trans.setOutputProperty(OutputKeys.METHOD,"html");
trans.setOutputProperty(OutputKeys.VERSION,"4.0");放在xsl文件里：
<xsl:output method="html" version="4.0"/>
