Estou tentando utilizar a função linkTo passando parâmetros mas não estou conseguindo. Segue meu código: Controller: 
@Resource
public class IndexController {

	private final Result result;
	
	public IndexController(Result result) {
		this.result = result;
	}

	@Path("/")
	public void index() {
		result.include("variable", "VRaptor!");
	}
	
	@Path("/{teste}")
	public void index(int teste) {
		
	}

}
JSP: 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>VRaptor Blank Project</title>
</head>
<body>
	It works!! ${variable} ${linkTo[IndexController].index[2]}
</body>
</html>
