Flex blazeds/lcds AMF serialization for transient variables

Question

I am using LCDS and Flex. When I am sending an object from java to Flex, I donot want to send all  the properties. As far as I know,  if you do not want to serialize make a  variable transient.
eg.
private transient Date birthDate;
public Date getBirthDate(){ 
    return birthDate;
public void setBirthDate(Date val){
    birthDate = val;
    //Some code here.
Now the serialized object should not have birthDate in it.  But When I  see the AMF logs , the object has the birthDate with value in it.
Does serialization looks into code and checks the private variable is  transient.( I don't understand how it has access to private property. I  am little confused.)
Should I mark variable as public. Then getters and setters make no sense  and moreover I write some code in setter method. So I need setter.
Questions:
I read in a book(Enterprise flex with blazeds by Brain Telintelo,  Chapter 15) that out of box Blazeds only serializes fileds that have  matching getters and setters. If this is the case, will blazeds even  bothers to check private property as transient.
Can some body please explain how normal serializtion( not amf  serializtion ) takes place and keeps track of private transient  variables even though they have public getters and setters.
How do I make a java variable not serialize in Flex/LCDS/BlazeDS environment.
I have 50-60 variables in objects and 4 or 5 varibales should not be seriablezed. So writing custion Serializer in such a large objects is a big pain. And another disadvantage I see is hibernate will not be able to use this object if I write my own serializer.

Is it possible to post your findings as well ? 
I'm encountering the same concerns with AMF and could use some help. 
Ideally, can you assist with the following:
1.  convert actionscript object graph to amf bytearray
2.  convert amf bytearray to actionscript object graph
3.  convert java object graph to amf bytearray
4.  convert amf byte array to java object graph 
Thanks,
