新人求教! tomcat 安装问题,急.

[caoxiongjun]

我下载了tomcat 5.5.17中文版exe版本 从http://www.jaxwiki.com
安装了之后,运行一从网上得到的源码,出现了以下错误,搞不懂啊,还请哪位大侠指教.

org.apache.jasper.JasperException: /index.jsp(1,1) 无法在web.xml或部署的JAR文件里 找到 绝对路径uri （http://java.sun.com/jsp/jstl/core）
org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:510)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:375)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)


index.jsp 如下:


<div class="maintext">
