EXT如何调用java程序

Question

[code="javascript"]chooseOrgTree.superclass.constructor.call(this, {
width: 200,
split: true,
root : this.orgTreeRoot,
loader: new Ext.tree.TreeLoader({
dataUrl: "/datadict/DetailPaceProjectServlet?parameter=queryRep",
clearOnLoad: false,
requestMethod: "GET",
processResponse: function(response,node,callback,scope){
var json = response.responseText;
try{
var o = eval("("+json+")");
node.beginUpdate();
for(var i = 0, len = o.length; i < len; i++){
var n = this.createNode(o[i]);
if(n){
node.appendChild(n);
}
}
node.endUpdate(event.stopEvent());
this.runCallback(callback, scope || node, [node]);
}catch(e){
this.handleFailure(response);
}
}
}),
listeners: {
'contextmenu':{
fn: this.onContextData,
scope: this
},
"click": function(node){
DictInfoPanel(node);
}
}
});[/code]这样， DictInfoPanel 是这样的 ，其实DictInfoPanel这里不知道该怎么写了
[code="javascript"]DictInfoPanel = function(node){
//获得右侧tab对象
Ext.Ajax.request({
waitMsg : '读取数据。。。',
url : "/datadict/DetailPaceProjectServlet?paraId="+node.id,
method : "GET",
callback : function(args, success, response) {
if(success){
var p = this.add(new DocPanel({
id: id,
cclass : cls,
html : response.responseText,
iconCls: Docs.icons[cls]
}));
this.setActiveTab(p);
}
},
scope: this
});
var panel = Ext.getCmp("dataDictCenterPanel");
var tab = panel.findById(node.id);
if(!tab){
tab = panel.add({
id: node.id,
xtype:"panel",
title:node.text,
closable:true,
layout:"fit",
items:[grid]
});
}
panel.setActiveTab(tab);
}[/code]

加个参数params:{参数名:"参数值",参数名:"参数值"}
