想用msagent 實現即時通訊 但是用javascript操作msagent的時候必須不斷刷新頁面，這肯定是不能忍受的,想到了流行的ajax技術，用dwr實現定時刷新 ，
1。在頁面里面加入
<script src='<%= request.getContextPath() %>/dwr/interface/ListWorkflowTaskAJAXProcess.js'></script>
<script src='<%= request.getContextPath() %>/dwr/engine.js'></script>
<script src='<%= request.getContextPath() %>/dwr/util.js'></script>
2。然后用
function InitList(){
? var frm = document.listWorkflowProgressForm;
? callAjax(frm.curStartRowNo.value,frm.sortAttribute.value,frm.sortOrder.value, retriveList);
? ? setTimeout("InitList()",<%=m_refreshInterval%>);
}
3。function callAjax(curStartRowNo, sortAttribute, sortOrder, retriveList){
? var frm = document.listWorkflowProgressForm;
? frm.curStartRowNo.value=curStartRowNo;
? frm.sortAttribute.value=sortAttribute;
? frm.sortOrder.value=sortOrder;
? ListWorkflowTaskAJAXProcess.getWorkflowTaskList(curStartRowNo, sortAttribute, sortOrder, frm.filterStepID.value, retriveList);//在javascript里面就可以調用java class了
}
4.msagent 參考代碼
<script>

var chName;

var agent;

var Merlin;

chName = "Merlin";

agent = new ActiveXObject("Agent.Control.2");

agent.Connected = true; agent.Characters.Load(chName,chName+".acs");

Merlin = agent.Characters(chName); Merlin.MoveTo(200,200); Merlin.Show();

Merlin.Play("Announce");

Merlin.Speak("歡迎來到detrox的個人主頁");

Merlin.Play("Explain");

Merlin.Speak("咳，這里收錄了detrox和他朋友的文章。希望您能喜歡。");

Merlin.Play("Idle1_1");

Merlin.Play("Pleased");

Merlin.Speak("請進吧，我的客人");

Merlin.MoveTo(600,300);

Merlin.Play("Surprised");

Merlin.Speak("哦對了，大家最近小心非典。多多注意哦");

Merlin.Play("Idle1_2");

Merlin.Play("GestureUp");

Merlin.Speak("祝您在這里愉快");

Merlin.Play("Read");

Merlin.Hide();

</script>
