EJB参数传递问题（急）

[rabies]

sessionbean中有
public boolean startServer(Vector room, Vector computer)
这样一个函数
但是返回回来之后Vector都变成了null
rmi要实现RemoteException 但是Vector应该实现了吧
谢谢～！！

[rabies]

to cbhyk 自定义的一个类，实现了啊

[rabies]

public boolean startServer(Vector room, Vector computer) {
try{
InitialContext initial = new InitialContext();
RoomHome home = (RoomHome)initial.lookup("Room");
Iterator roomEJB = home.findAll().iterator();
Room roomRemote = null;
RoomModel roomModel=null;
//collection 's interator
while(roomEJB.hasNext())
{
Object roomObj = roomEJB.next(); //get one collection
roomRemote = (Room)roomObj; //change to Room remote
roomModel = new RoomModel(roomRemote.getRoomID(),
roomRemote.getRoomName(),
roomRemote.getPricePerMin());
System.out.println(roomModel.getRoomID());
//creat roomModel
room.add(roomModel); //add room model to array list
System.out.println(room.size());
}
... ...

System.out.println(room.size());显示了数字
但是在调用处
public boolean startServer(Vector room,ArrayList computer)
{
try{
ServiceLocator locator = ServiceLocator.getInstance();
home = (SystemControlHome) locator.getHome(sessionName,1);//.getHome(sessionName ,1);
systemControl=home.create();
systemControl.startServer(room,computer);
System.out.println(room.size()+"---------------------");
return true;
}

System.out.println(room.size()+"---------------------");
显示的则是0

Vector
你看一下doc,我记得好像它没有实现呢???

我们还年轻牛奶会有的奶牛也会有的
可天天在 csdn 混这些会有吗 ??

先看看api再下结论.

函数名有没有出错？StartServer(*,*)

[tianboguang]

Vector已经实现了序列化接口，是合法的EJB参数，肯定是其他地方出了什么问题。

[hutlyx]

Vector实现了序列化接口。
Class Vector

java.lang.Object
|
+-java.util.AbstractCollection
|
+-java.util.AbstractList
|
+-java.util.Vector

All Implemented Interfaces:
Cloneable, Collection, List, RandomAccess, Serializable
你的错误代码呢？

[cbhyk]

放到Vector里的对象实现Serializable没有?
