可以看一下struts代的例子中的struts-exercise-taglib.war

1、jsp中代码
<bean:define id="theList" name="deviceTypeInfoForm" property = "deviceCategoryList" type = "java.util.ArrayList"/>
<html:select property="deviceCategory" onchange="submitForm(this.form)">
<option >请选择种类</option>
<html:options collection="theList" property="deviceCategory" labelProperty="deviceCategoryName"/>
</html:select>
2、form

public class DeviceTypeInfoForm extends ActionForm {
//下面三个成员要有对应的getter和setter方法
private String deviceCategory;
private String deviceCategoryName;
private ArrayList deviceCategoryList;

//deviceCategoryList里面保存的是DeviceTypeInfoForm 实例
//下面是塞实例的代码
public DeviceTypeInfoForm(String listName,String id ,String name){
if(listName.equals("Category")){
this.deviceCategory=id;
this.deviceCategoryName=name;

}
//..................其它代码.......

}
public DeviceTypeInfoForm(){
deviceCategoryList=new ArrayList();
deviceCategoryList.clear();
deviceCategoryList.add(new DeviceTypeInfoForm("Category","0","种类一"));
deviceCategoryList.add(new DeviceTypeInfoForm("Category","1","种类二"));
deviceCategoryList.add(new DeviceTypeInfoForm("Category","2","种类三"));
deviceCategoryList.add(new DeviceTypeInfoForm("Category","3","种类四"));

//......................

}
}

3、配置文件
<form-bean name="deviceTypeInfoForm" type="dms.form.baseinfo.device.DeviceTypeInfoForm" />
<action
path="/deviceTypeInfoAction"
input="/basic/deviceTypeInfoList.jsp"
name="deviceTypeInfoForm"
type="dms.action.baseinfo.device.DeviceTypeInfoAction"
validate="false">
<forward name="listAllOk" path="/basic/deviceTypeInfoList.jsp" />
<forward name="addjsp" path="/basic/deviceTypeInfo.jsp" />
</action>
//以上就是我的代码的主要部分，

在JB的安装目录下的extras\jakarta-struts-1.0.2-src\web\exercise-taglib有好多例子，你可以参考！
