Jaxb - Ignore unknown Attributes

I have a parent class which contains an enum "ActionType".

@XmlRootElement(name="Action")
public class ActionDto {
[...] ActionType type;
}

and some child-classes which extends ActionDto and have more special attributes like password (the LoginDto).

It's a server-client-connection. I want to send some data from my client to my server. So I serialize it (I use Jaxb) and deserialize it to an ActionDto-object.

An example for a LoginDto-Object:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Action>
<type>LOGIN</type>
<password>Testpassword</password>
</Action>

I get an error if I want to deserialize it to an ActionDto-object - I think it's caused by the password-attribute. Can I make the Jaxb-unmarshaller ignore those unknown attributes?

Is there an other possibility to unmarshal it directly to my LoginDto-Object (The server receives just a xml-String, I don't know the special type) ?

By default a JAXB implementation will ignore unknown elements. If it is throwing an exception the default ValidationEventHandler has been replaced on the Unmarshaller. You will need to replace the one that with one that is less sensitive.
