jsp文件拆分后“模板文本中不允许使用#{..}”答案

【问题标题】："#{..} is not allowed in template text" after jsp file splittingjsp文件拆分后“模板文本中不允许使用#{..}”

【问题描述】：

我正在使用一个

<s:radio  list="#{'used': 'Mark as used', 'available': 'Mark as available'}" name="selections" value="%{'used'}"></s:radio>

在 index.jsp 页面中添加标签，它可以正常工作。

如果我在另一个 .jsp 页面中包含相同的代码，该页面随后包含在初始 index.jsp 文件中，我会收到以下错误：

我该如何解决这个问题？

【问题讨论】：

#{...} is not allowed in template text

标签： jsp jsf

【解决方案1】：

您需要在 JSP 顶部声明 <s:xxx> 标签库。否则，<s:radio> 将不会被识别为完全有价值的标签，而只会被解释为模板文本。

另见：

#{...} is not allowed in template text
