Everyone is saying use value objects. So you have your ServerBean return a
java class that just implements java.io.Serializable which is passed back to
your client. Client does what it wishes to this value object, which is
where all the get/set methods are. You can do validation here if you
please. Then when you are ready to update, just pass the value object back
and tada, you have all your parameters set in one foul swoop. So I
typically have something like
public class ServerObject (this is your EJB)
{
public ServerModel getDetails() throws java.rmi.RemoteException
{
...
}
public void update(ServerModel model)
throws java.rmi.RemoteException,
SomeAppExceptionForInvalidStateIfYouLike
{
...
}
}
public class ServerModel implements java.io.Serializable
{
public String getProperty1() {}
public void setProperty1(String prop) {}
public int getProperty1() {}
public void setProperty1(int prop) {}
}
