解决方案 »

  1.   

    用的是什么版本
    struts2-core-2.x.xx.jar
    应该 2.0.xx 提供了template/ajax/你看看你的struts2-core-2.x.xx.jar/template/下有没有 ajax这个文件夹
    好像高版本的没有
      

  2.   

    更新下sturts2版本
    引入struts2-dojo-plugin.jar页面
    <%@ taglib prefix="sx" uri="/struts-dojo-tags"%><sx:head/>
      

  3.   

    struts2.1.12 之后的版本把ajax相关的放到dojo中了
      

  4.   


    上面的这几个地方我都注意到 了 jar包都加进去了，最新的2.1.6就ok了！
      

  5.   

    参考下 struts2-core-2.0.9.jar、 struts2-spring-plugin-2.0.9.jar、 xwork-2.0.4.jar这个jar包组合配置。
      

  6.   

    org.apache.jasper.JasperException: Expression parameters.parseContent is undefined on line 45, column 28 in template/ajax/head.ftl. - Class: freeer.core.TemplateObject
    File: TemplateObject.java
    Method: assertNonNull
    Line: 124 - freeer/core/TemplateObject.java:124:-1
    org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:522)
    org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:416)
    org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:342)
    org.apache.jasper.servlet.JspServlet.service(JspServlet.java:267)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
    org.apache.struts2.dispatcher.FilterDispatcher.doFilter(FilterDispatcher.java:389)
      

  7.   

    基于2楼导入那个包之后我也报这个错了  后来发现重复定义了 
    <s:head />
    <sx:head />去掉第一个就行了  这种情况也是报这个错
