我要的效果：
随着下拉框选择的变动，这内容列表也随着变动

这是页面的源码:

<s:form action="" method="post" theme="simple">
<table align="center" border="1" width="378" >
<tr>
<td align="center">
<s:select list="organList" listKey="organId" listValue="organName" name="roleSelect" id="roleSelect" cssStyle="width:170px" onchange="changeSelect()"></s:select>
</td>
<td colspan="2" align="center">
<s:radio list="{'部门','角色'}" name="grRadio" id="Radio" value="'部门'"></s:radio>
</td>
</tr>
<tr>
<td rowspan="3" align="center">
<s:select list="userList" listKey="userId" listValue="userName" name="userSelect" id="userSelect" size="10" cssStyle="width:170px"></s:select>
</td>
<td align="center" align="center">
<input type="button" name="goButton" id="goButton" value=">>"></input>
</td>
<td rowspan="3" align="center">
<s:select list="{'1','2','2'}" name="targeSelect" id="targeSelect" size="10" cssStyle="width:170px"></s:select>
</td>
</tr>
<tr>
<td align="center">

<input type="button" name="backButton" id="backButton" value="<<"></input>
</td>
</tr>
<tr>
<td></td>
</tr>
<tr>
<td colspan="3">
<s:textarea name="infoTestarea" id="infoTestarea" cssStyle="width:100%;height:110px"></s:textarea>
</td>
</tr>
<tr>
<td colspan="2">
<s:submit name="send" id="send" value="发送"></s:submit>
</td>
<td align="right">
<s:label>信息发送条数</s:label>
</td>
</tr>
<tr>
<td colspan="2" align="right" style="width:60%">
<s:label value="模板:"></s:label>
</td>
<td align="left" style="width:40%">
<s:select list="{}" name="modeSelect" id="modeSelect" cssStyle="width:100%"></s:select>
</td>
</tr>
</table>
</s:form>

"changeSelect()"是我写的一个script

function changeSelect(){
var url = 'changeSelect!userListOfOrgan.action';
var params = {
roleSelect:$('#roleSelect').attr('value')
};
alert(params);
jQuery.post(url,params,callback);
}

function callback(data) {
alert(data.userList);我想看看所要数据是否取得
}

changeSelect!userListOfOrgan.action'
对应的action类为

public String userListOfOrgan() throws Exception {
System.out.println(roleSelect + "``````````````````````````````````````````````````");
userList = userService.getUserListByOragn(roleSelect);
//userList是可以成功取得的
System.out.println("1111111111111111111111111111111111");
return Action.SUCCESS;
}

我想要将查出来的值userList，插入内容列表中。
这是我struts.xml
<package name="ajax" extends="json-default">
<action name="changeSelect" class="SendMessageAction">
<result type="json"></result>
</action>
</package>中的配置

现在报错
