extjs从数据库中读取数据返回到前台表单，js文件里面怎么写？

Ext部分：
Ext.onReady(function(){
var myFormPanel = new Ext.form.Panel({
title: 'Client and routing info',
renderTo:Ext.getBody(),
defaults:{
xtype:'textfield'

},
items: [{
fieldLabel: 'Client',
name: 'clientName'
}, {
fieldLabel: 'Port of loading',
name: 'portOfLoading'
}, {
fieldLabel: 'Port of discharge',
name: 'portOfDischarge'
}]
});
myFormPanel.getForm().load({
url: 'page/formload.jsp',
params: {
consignmentRef: 'myConsignmentRef'
},
failure: function(form, action) {
Ext.Msg.alert("Load failed", action.result.errorMessage);
}
});

});
JSP部分
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String forms = "{success: false,errorMessage:'errorMessage',data: {clientName: 'Fred. Olsen Lines',portOfLoading: 'FXT',portOfDischarge: 'OSL'}}";

response.getWriter().write(forms);
%>
