<s:form action="papercreate">
			<table border="1">
				<tr>
					<td>
						check
					</td>
					<td>
						ID
					</td>
					<td>
						Content
					</td>
					<td>
						A
					</td>
					<td>
						B
					</td>
					<td>
						C
					</td>
					<td>
						D
					</td>
					<td>
						True
					</td>
				</tr>
				<%
					List<Questions> list = (ArrayList) session
								.getAttribute("questionslist");

						if (list != null) {
							for (Questions qs : list) {
				%>
				<tr>
					<td>
						<input type="checkbox" name="questionid" value=<%=qs.getId()%> />
					</td>
					<td><%=qs.getId()%></td>
					<td><%=qs.getText()%></td>
					<td><%=qs.getAnswerA()%></td>
					<td><%=qs.getAnswerB()%></td>
					<td><%=qs.getAnswerC()%></td>
					<td><%=qs.getAnswerD()%></td>
					<td><%=qs.getAnswerTrue()%></td>
				</tr>
				<%
					}
						}
				%>
				<s:submit value="submit" />
			</table>
		</s:form>

生成html代码：

<form id="papercreate" name="papercreate" onsubmit="return true;" action="/zpgl0.4/papercreate.action" method="post"><table class="wwFormTable">
	<table border="1">
			<tr>
				<td>
					check
				</td>
				<td>
					ID
				</td>
				<td>
					Content
				</td>
				<td>
					A
				</td>
				<td>
					B
				</td>
				<td>
					C
				</td>
				<td>
					D
				</td>
				<td>
					True
				</td>
			</tr>
			
			<tr>
				<td><input type="checkbox" name="questionid" value=2 /></td>
				<td>2</td>
				<td>1+5</td>
				<td>3</td>
				<td>3</td>
				<td>3</td>
				<td>3</td>
				<td>D</td>
			</tr>
			
			<tr>
				<td><input type="checkbox" name="questionid" value=3 /></td>
				<td>3</td>
				<td>1+3</td>
				<td>2</td>
				<td>3</td>
				<td>4</td>
				<td>5</td>
				<td>C</td>
			</tr>
			
			<tr>
				<td><input type="checkbox" name="questionid" value=5 /></td>
				<td>5</td>
				<td>1+4?</td>
				<td>2</td>
				<td>3</td>
				<td>4</td>
				<td>5</td>
				<td>D</td>
			</tr>
			
			<tr>
				<td><input type="checkbox" name="questionid" value=6 /></td>
				<td>6</td>
				<td>1+1=?</td>
				<td>2</td>
				<td>3</td>
				<td>4</td>
				<td>5</td>
				<td>A</td>
			</tr>
			
			<tr>
    <td colspan="2"><div align="right"><input type="submit" id="papercreate_0" value="submit"/>
</div></td>
</tr>

		</table>
	</table></form>

java代码：

public class paperCreate extends ActionSupport {
	private String[] questionid;
			
	public String[] getQuestionid() {
		return questionid;
	}
	public void setQuestionid(String[] questionid) {
		this.questionid = questionid;
	}
	@Override
	public String execute() throws Exception {	
		for (int i=0;i<questionid.length;i++)
			System.out.println(questionid[i]);
		return "success";
	}
}
