struts2.0.11版本不支持el,因而以前在低版本下寫和程式將不能正常運行：
下面是一段分頁所用的循環(huán):
<c:forEach var="i" begin="1" end="${requestScope.page.afterPage}" step="1">
    <c:if
     test="${requestScope.page.indexPage<requestScope.page.totalPage && requestScope.page.indexPage+i<requestScope.page.totalPage}">
     <s:url id="afterUrl" value="/photoItemsList.html">
          <s:param name="indexPage" value="${requestScope.page.indexPage+i}" /><!-- struts2.0.11中已不支持el，因而<s:url>將取不到相關(guān)值-->
     </s:url>
     <s:a theme="ajax" href="%{afterUrl}" indicator="indicator" showLoadingText="false" targets="pageItems">
          <c:out value="${requestScope.page.indexPage+i}" />&nbsp;</s:a>
    </c:if>
   </c:forEach>

修改成如下：
<c:forEach var="i" begin="1" end="${requestScope.page.afterPage}" step="1">
    <c:set value="${i}" var="var"/>
    <c:if   test="${requestScope.page.indexPage<requestScope.page.totalPage && requestScope.page.indexPage+i<requestScope.page.totalPage}">
     <s:url id="afterUrl" value="/photoItemsList.html">
          <s:param name="indexPage" value="#request.page.indexPage+#attr.var" />
     </s:url>
     <s:a theme="ajax" href="%{afterUrl}" indicator="indicator" showLoadingText="false" targets="pageItems">
          <c:out value="${requestScope.page.indexPage+i}" />&nbsp;</s:a>
    </c:if>
   </c:forEach>
