XStream Classe com atributo List

Programação Java
#1

Prezados,
Poderiam me ajudar, é o seguinte:
Classe que pega o arquivo

arquivo = new File(".\.\arquivos\producaoTakes.xml");
			FileReader arquivoXML = new FileReader(arquivo);
			BufferedReader leitor = new BufferedReader(arquivoXML,2*1024*1024);
			String linha = null;
			String xml = "";
			do{
				linha = leitor.readLine();
				if(linha != null)
					xml += linha;
			}
			while(linha != null);
			xstream.alias("Menu", Menu.class);
			xstream.alias("Root", Root.class);
			xstream.aliasAttribute(Menu.class, "roots", "Root");
			xstream.aliasAttribute(Root.class, "text", "text");
			xstream.aliasAttribute(Root.class, "value", "value");
			Menu menu = (Menu)xstream.fromXML(xml);
			
			return menu;

Classe Menu:

package root;

import java.util.List;
public class Menu {

	private List<Root> roots;
	
	public List<Root> getRoots() {
		return roots;
	}

	public void setRoots(List<Root> root) {
		this.roots = root;
	}
	
	
	
}//fim classe

CLasse Root:

public class Root {

	
	private String text;
	private String value;
	
	public String getText() {
		return text;
	}

	public void setText(String text) {
		this.text = text;
	}

	public String getValue() {
		return value;
	}

	public void setValue(String value) {
		this.value = value;
	}

	public Root() {
		
	}

}

Tem que voltar um objeto de menu com um atributo List com os objetos Root. Mas eu recebo o seguinte erro:

XML:

<Menu>
<Root>
	<text>1964 /40 ANOS DEPOIS</text>
	<value>1964 /40 ANOS DEPOIS</value>
</Root>
</Menu>
#3

Faça um teste ao contrario com o to.xml, gere um xml de acordo com o seu objeto e veja se é igual ao que vc esta tentando ler.

#4

Resolvido!!!
Só usar:

xstream.addImplicitCollection(Menu.class,"roots" , Root.class);

Valeu!!!

#5

Valeu a resposta!
Resolvi da forma que coloquei aí.
