considering about local and remote instance ...

[flower]

Hello,

Maybe example:
I have got class Person (might be entity):

public class Person implements java.io.Serialization {
 Strnig name;
 public Person(string name) { this.name=name; }
 get/setName()
}

And I have got Stateless bean with one method:

void changeName(Person p, String name) {
 p.setName(name);
}

Ok and I do something like this:

MyStatelessBean msb = ctx.lookup(..);
Person p = new Person("flower");
System.out.println(p.getName()); // [stdout] flower
msb.changeName(p,"RedFlower");
System.out.println(p.getName()); // [stdout] flower

Ok, so ..
I calling changeName(p,"...") ...
application serialized p and sent it to application server (AS)
AS convert serialized data into p' instance
AS change p' instance
calling was end and AS _didn't_ send back p` instance.

Consequently in client side , p wasn't changing.

Shouldn't they replace local p instance by p' ?

Why?
do Person changeName(Person p, String name) {
p.setName(name);
return p;
}

if you want to be sure

Ok, but after calling

MyStatelessBean msb = ctx.lookup(..);
Person p = new Person("flower");
p = msb.changeName(p,"RedFlower");

p is different instance.
So if I had got many references to 'p-instance' before calling this method, only one reference will be changed after.
