--  请教jaxp基础问题！
我有一个jsp文件如下：

<%@ page
  import="javax.xml.parsers.*,
  org.w3c.dom.*,
  javax.xml.transform.*,
  javax.xml.transform.stream.*,
  java.io.*" %>

<%
StreamSource xml = new StreamSource(new File("Fireworks.xml"));

StreamSource xsl = new StreamSource(new File("FireworksHTML.xsl"));

StreamResult result = new StreamResult(out);

TransformerFactory tFactory = TransformerFactory.newInstance();

Transformer transformer = tFactory.newTransformer(xsl);

transformer.transform(xml, result);
%>

我其他jsp文件都能正常运行，运行这个文件就有错。请问运行这个文件是否需要下载jaxp1.3软件包，在哪里下载？

是这样的，我看有的地方说只要我安装了最新版本的JDK，那么jaxp就包含在里边了，就不用特别下载jaxp软件包了，我不知道是不是这样，我的JDK是最新版本的。

最开始运行的错误是找不到xalan.jar，然后我就下了一个xalan.jar文件放到C:\Program Files\Apache Software Foundation\Tomcat 5.0\common\lib 目录下。

现在的错误是：

type Exception report

我帮你看了，不是你的jsp代码有问题，而是第二个xsl文件有问题，它的第二行：
<?xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
多了个“?”，把它修改为：
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

jsp就可以运行了，没有错误提示。你试下看。
