struts2标签里不能嵌套别的标签，包括他自己
你可以这样
<input type="hidden" name="department.dep_id" value="${updateDep.dep_id}">

<s:textfield name="department.dep_name"></s:textfield>
[解决办法]
错误报告是这样的：attribute value does not accept any expressions
意思就是，在value属性中不能放任何的表达式。也就是说你用value="aaa"是可以的，但不能放任何描述性内容。
如果你想在java赋值传给画面，那么就赋值给department.dep_name，然后在jsp里如下写：
<s:textfield name="department.dep_name"></s:textfield>
