Matching XML structure to unmarshal classes

Question

Hello
I am wanting to use data binding ( Castor or other ) to parse xml mesages recieved by a server.
Can someone tell me if it possible to achieve the folowing:
I am goig to have several types of message structures coming into the server which will need binding. The following two example are fictitious but demonstrate my question.
MESSAGE 1
<message>
     <type>type1</type>
</message>
Unmarsal class as follows:
public class Message1
    private String type;
    public Message1( String type )
        this.type = type;
    public Message1() { }
    public String getType()
        return type;
    public void setType(String type)
        this.type = type;
}MESSAGE 2
<message>
     <type>type2</type>
     <somevar>xyz</somevar>
     <anothervar>xyz</anothervar>
</message>
Unmarsal class as follows:
public class Message2
    private String type;
     private String somevar;
     private String anothervar;
    public Message2( String type, String somevar, String anothervar)
        this.type = type;
          this.somevar = somevar;
          this.anothervar = anothervar;
    public Message2() { }
    public String getType()
        return type;
    public String getSomeVar()
        return somevar;
    public String getAnotherVar()
        return anothervar;
    public void setType(String type)
        this.type = type;
    public void setSomeVar(String somevar)
        this.somevar = somevar;
    public void setAnotherVar(String anothervar)
        this.anothervar = anothervar;
}The marshalling of these messages is simple when I know what the message structure is however in the server It will not know this.
My question Is how do I match the messages and classes?
Kindest Regards.
