        <select id="jumpPage" name="jumpPage" onchange="this.form.submit()">

        <c:forEach items="${9 }" var="number">

        	<c:when test="${number == 3 }">

        		<option selected value="3">3</option>

        	</c:when>

        	<c:otherwise>

        		<option value="${number }">${number }</option>

<c:forEach items="${9 }" var="number"></forEach>
items=EL表达式这个表达式只能为集合,你那报的那个错是说没法迭代items

<c:forEach begin="1" end="9" var="number">
<c:when test="${number == 3 }">
<option selected value="3">3</option>
</c:when>
<c:otherwise>
<option value="${number }">${number }</option>
</c:otherwise>
</c:forEach>

不行,报错了:
- Servlet.service() for servlet jsp threw exception
javax.servlet.jsp.JspTagException: Don't know how to iterate over supplied "items" in <forEach>
