 初歩的な質問だとは思うのですが、アドバイスをお願いします。
+※UserActionFormはsetter,getterクラス。LoopListFormはListを、別のListに格納するクラスです。

+```LoopListForm
+package model;
+import java.util.List;
+import org.apache.struts.action.ActionForm;
+public class LoopListForm extends ActionForm {
+	private List<UserActionForm> loop;
+	public void setLoop(List<UserActionForm> list) {
+		loop = list;
+	}
+	public List<UserActionForm> getLoop(){
+		return loop;
+	}
+}
+```
+今の使い方としては、UserActionForm型のListのSetterに値を代入し、
+そのListをLoopListFormに格納しています。
+```java
+List<UserActionForm> list = new ArrayList<UserActionForm>();
+LoopListForm loop = new LoopListForm();
+～省略～
+UserActionForm uafList = new UserActionForm();
+　uafList.setUserID(userID);
+　uafList.setWorkTime(workingTime);
+　uafList.setOverTime(overTime);
+　uafList.setEarlyCount(earlyCount);
+　uafList.setLateCount(lateCount);
+　uafList.setWorks(count);
+　list.add(uafList);
+　loop.setLoop(list);
+　}
+}
+	request.setAttribute("LoopListForm", loop);
+～省略～
+```
+setAttributeした値はJSPで受け取っているのですが、
+そこでキャストするときに詰まっています。
+```JSP
+<%
+List<model.LoopListForm> list = (List)request.getAttribute("LoopListForm");　//ここでキャストする方法がわからない。
+if(list != null){
+System.out.println(list);
+System.out.println(list.size());
+for(int i = 0 ; i < list.size() ; i++){
+model.UserActionForm uaf = list.get(i);
+%>
+<label>名前：?</label><br>
+<label>今月の勤務時間の合計：<%= uaf.getWorkTime() %>分</label><br>
+<label>今月の残業時間の合計：<%= uaf.getOverTime() %>分</label><br>
+<label>勤務日数：<%= uaf.getWorks() %>日</label><br>
+<label>遅刻日数：<%= uaf.getLateCount() %>日</label><br>
+<label>早退日数：<%= uaf.getEarlyCount() %>日</label><br>
+★★★★★
+<br>
