在字符模板中使用layout标签的问题?报错

@闲.大赋 你好，想跟你请教个问题：

下边是使用模板的代码。模板里边有一部分内容需要动态生成，想使用layout标签来实现，动态内容作为layoutContent传进去，page.html里边是除了动态内容外固定的内容。但现在使用字符串模板时，调用layout标签总是报错，错误信息在代码下边。麻烦您看看

public ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response) throws Exception {
		response.setContentType("text/html;charset=UTF-8");
		String tplContent="<%layout(\"/page/page.html\"){%>动态内容<%}%>";
		GroupTemplate group=GroupTemplateUtil.getGroup();
		try {
			Template tpl=group.getStringTemplate(tplContent);
			tpl.getText(response.getOutputStream());
		} catch (BeeException e) {
			e.printStackTrace();
		}
		return null;
}
