<%
for(int i=0;i<10;i++){

i: <%=i %>
<%
}
%>
struts 标签或C标签都可以或JSP代码
<c:foreach var="l" items="${list}">
${l}
</c:foreach>
<c:forEach var="model" items="modelList">
</c:forEach>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %><c:forEach var="score" items="${scoreList}">
${score}
</c:forEach>
<c:forEach var="l" items="9-paginationSupport2.items.size" >
<tr>
<td> </td>
<td> </td>
<td> </td>
<td> </td>
<td> </td>
</tr>
</c:forEach>
<c:forEach var="l" items="9-paginationSupport2.items.size" >这只能是集合啊数字不行
<c:forEach varStatus="stauts" begin="0" end="9">
    ${stauts.count}
    </c:forEach>
<c:forEach begin="1" end="10" step="1">
a
</c:forEach>
打印10个a
<s:if test="paginationSupport2.items.size<9">
<c:forEach varStatus="stauts" begin="paginationSupport2.items.size" end="9">
<tr>
<td> </td>
<td> </td>
<td> </td>
<td> </td>
<td> </td>
</tr>
</c:forEach>
</s:if>我这样写的出错
严重: Servlet.service() for servlet jsp threw exception
java.lang.NumberFormatException: For input string: "paginationSupport2.items.size"
paginationSupport2.items.size什么东西
在<%%>里可以写java语句，你试试吧
你先注掉下面的、看看你的paginationSupport2.items.size能打印不
<%=paginationSupport2.items.size%>
<s:if test="paginationSupport2.items.size<9">
<c:forEach varStatus="stauts" begin="paginationSupport2.items.size" end="9">
<tr>
<td> </td>
<td> </td>
<td> </td>
<td> </td>
<td> </td>
</tr>
</c:forEach>
</s:if>
换成
<%=paginationSupport2.items.size%>
楼主可以把问题解说的再细点。
另：可以参考下jstl标签的<c:forEach>
