按java web王者归来做strut2练习使用<struts:head theme:"ajax">报错

org.apache.jasper.JasperException: Template /template/ajax/head.ftl not found

加入struts2-dojo-plugin-2.1.6包

并在jsp里引入<%@ taglib prefix="sx" uri="/struts-dojo-tags"%><sx:head />

这是又继续报错：

2014-5-12 21:43:14 freemarker.log.JDK14LoggerFactory$JDK14Logger error

严重: Template processing error: "Expression parameters.parseContent is undefined on line 45, column 28 in template/ajax/head.ftl."
