用flying saucer将html文件生成pdf，总会报以下错误信息，求解！！

[东东不邪]

参考过很多网上的例子，包括http://www.iteye.com/topic/509417 可就是没一个测试成功。
环境：resin服务器+core-renderer.jar+itext2.0.8，到底为什么呢？？

解析你的XHTML的时候遇到问题了，
首先确认你的HTML元素全都闭合了，
再确认你的HTML头是否为：
<?xml version="1.0" encoding="UTF-8"?>

楼主 问题解决没呢？ 我也同问

相信你的問題已經解決了吧？后來發現是包沖突的問題，重新整理了一下jar包，解決了

[freechan2006]

楼主可以告诉我怎么解决的吗？具体是哪个包冲突了呢。我的邮箱是[e-mail]，谢谢！

[东东不邪]

具体哪个我忘了，新建一个project就好了[Quote=引用 4 楼 freechan2006 的回复:]

[/Quote]同意，flying saucer对html要求相当严格

[eric_cj]

xalan.jar ：org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl
rt.jar ： com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl
冲突了，如果工程中可以不要“xalan.jar”这个包，删除即可
如果需要，重新指定下类加载就可以了:System.setProperty("javax.xml.transform.TransformerFactory", "com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl");

[eric_cj]

同理，还有xerce也会有此问题，重新加载为：System.setProperty("javax.xml.parsers.DocumentBuilderFactory", com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl");

[info_he]

避免误人子弟，特别说明7楼和8楼是正解，在此特别谢过

[programdolt]

7,8楼太给力了

[boblee_2008]

7,8楼，是如何解决的呢？？
