Pessoal.
Existe alguma diferença na pratica entre retornar um List e um List em um Webservice ?
Afeta a performance ou a aplicação cliente ?

Até onde sei pro webservice não muda nada, a diferença é que com Generics você esta dizendo que a List será daquele tipo de objeto, mas performáticamente não sei se tem diferença real.
Abraços,
nao afeta a perfomance de forma nenhuma. quando o codigo eh compilado, o generic vai ser apagado do byte code, por causa da compatilibidade retroativa…ou seja…da no mesmo…
E teoricamente nem um List você deveria retornar, como fica quando o seu cliente não tiver um objeto equivalente para mapear?
Valeuuu…
E eu retornaria oque ? Um Object[] ?
Ando tendo um outro problema… no codigo abaixo que estou usando pra teste.
@WebMethod(operationName = "getS")
public List getS() {
//TODO grava o seu código de implementação aqui:
TransactW tw1 = new TransactW();
tw1.setId(1);
tw1.setCliente("ssddfsfsdfsd");
tw1.setIum("XXXXXXXXX");
TransactW tw2 = new TransactW();
tw2.setId(2);
tw2.setCliente("AAAAAPbbbcbr");
tw2.setIum("XXXXXXXXXZZZZZ");
TransactW tw3 = new TransactW();
tw1.setId(3);
tw1.setCliente("333333Psdfdsf");
tw1.setIum("XXXXXXXXX33333");
List l1 = new ArrayList();
l1.add(tw1);
l1.add(tw2);
l1.add(tw3);
return l1;
}
Está me dando a seguinte Exception (abaixo)…
Alguma dica ?? Valeuuuu
