在学习seam中的numberguess的例子，
遇到下面的问题，开发环境是eclipse+jboss tools, 部署好后，报出下面的错误，说“numberGuess.jspx”中的“jsp:output”标签不识别，请问是什么地方有问题导致的？ javax.servlet.ServletException: /numberGuess.jspx @11,90 <jsp:output> Tag Library supports

附上numberGuess.jspx文件的内容
<?xml version="1.0"?> <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:s="http://jboss.com/products/seam/taglib" xmlns="http://www.w3.org/1999/xhtml" version="2.0"> <jsp:output doctype-root-element="html" doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" doctype-system="http://www.w3c.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"/> <jsp:directive.page contentType="text/html"/> <html> <head> <title>Guess a number...</title> <link href="niceforms.css" rel="stylesheet" type="text/css" /> <script language="javascript" type="text/javascript" src="niceforms.js"><!-- --></script> </head> ..... ..... ..... |

把 <jsp:output doctype-root-element="html" doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" doctype-system="http://www.w3c.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"/> <jsp:directive.page contentType="text/html"/> 给删除了，就正常了，不懂啊，谁给咱解释解释 |

从stack trace来看，是因为"http://java.sun.com/JSP/Page" 这个namespace中没有定义“output”这个元素。
你是在哪个server上跑的？这个server支持的servlet/jsp规范是什么版本？ |
