How to get autogenerated id after save

As soon as the user saves the data I want that the user should be transferred to another url and therefore I had written a action which extends SaveAction and implements IForwardAction but the problem is that I don't know how to get id of the saved data?

My Class has declared id as

@Id @Hidden @GeneratedValue(generator="system-uuid")
@GenericGenerator(name="system-uuid", strategy = "uuid")
private String id;

Action Code
--------------------

public class SaveAction extends org.openxava.actions.SaveAction implements IForwardAction {
    private String url;
    @Override
    public void execute() throws Exception {
        // TODO Auto-generated method stub
        id=(String)getView().getKeyValues().get("id");
        super.execute();
       
    }
    public String getForwardURI() {
        // TODO Auto-generated method stub
        return "/xava/custom/forward.jsp?url="+url;
    }

    public boolean inNewWindow() {
        // TODO Auto-generated method stub
        return false;
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }
}

Thanks in advance
