If your object can be represented as a 'JavaBean', then you can use
Java2WSDL and WSDL2Java to create client and server code to perform the
communications - and it automatically defines the WSDL to use a serializer
that works.
In other words, if your object can be represented as a bean then a
Serializer does exist.
I actually put a pretty detailed example of this in my Struts book -
"Struts Kickstart" by SAMS publishing.

Subject: how write a Serializer
Hi all,
How to send send and receive an Object for which no Serializer had been
previously written ?
I mean : I had created an Object as follow :
public class Container {
private int id;
private float x;
private float y;
public Container (int id, float x, float y) {
this.id = id;
this.x = x;
this.y = y;
}
(...)
} // Container
but when I try to receive one of them from my web service, I get the
following exception :
Exception in thread "main" java.io.IOException: No serializer found for
class collection.Container in registry
org.apache.axis.encoding.TypeMappingImpl@2d15a9
java.io.IOException: *No serializer found for class collection.Container
in registry* org.apache.axis.encoding.TypeMappingImpl@2d15a9

So my question is how to write the corresponding Serializer ?
If anyone had an idea ...
Thanx
Sam
