<select>标签利用<s:if>来显示数据

class Person {

	private String id;
	private String name;

	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public Person(String id, String name) {
		this.id = id;
		this.name = name;
	}
}

jsp页面

<select name="choice">
					<s:iterator value="#request.list2" id='i' status='st'>
						<option value="<s:property value="id" />"
							<s:if test="id==choice">
							selected='selected' 
							</s:if>>
							<s:property value="name" />
						</option>
					</s:iterator>
			</select>

说明：
list2存的是Person的对象。


choice 是jsp和Action交互的变量。
