Hi,
thanks a lot for the help. I'm despaired..
This code, work ok in J2ME. If I try get the String or Int like
return, work fine. But the error it occurs when I try readObject in
microHessian.
I can get the object, but I can't serialize again in my object (TO).
How can I resolve? I try (as you it said) implement MicroHessianOutput
in my web Service. The objective is in My Web Service, I search in
DataBase a List o objects, ans return this objects from my client
(J2ME - CDC).
new code WebService:
public void metodoSimples() throws Exception {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
MicroHessianOutput out = new MicroHessianOutput(bos);
ProdutoTO prod = new ProdutoTO();
prod.setCodigo(1);
prod.setDescricao("prod palhaco");
out.writeObject(prod);
}
Client J2ME code:
String url =
"http://localhost:8084/br.com.rosaFlores.WebService/test";;
HttpConnection c = (HttpConnection) Connector.open(url);
c.setRequestMethod(HttpConnection.POST);
OutputStream os = c.openOutputStream();
MicroHessianOutput out = new MicroHessianOutput(os);
out.startCall("metodoSimples");
out.completeCall();
os.flush();
InputStream is = c.openInputStream();
MicroHessianInput in = new MicroHessianInput(is);
in.startReply();
Object obj = in.readObject(null);
--
PS: this code don't work. Now, I can't read the object...
But in MicroHessian, I dont have the startMessage() or close(), as my last code.
Did you have any idea? How van I make this simple code work? Ist very
simple. I need transfer a List of objects (Car, Product, Client, etc..
) as POJO in my client aplication (J2ME - CDC).
The sample that I found in hessian site, just work for J2SE client.
I wiil be returna array of byte (byte[]) ? Or I will be return void,
and write object (as sample) and readObject in my client?
thanks a lot!

Server code:
public byte[] returnTO() throws Exception {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
Hessian2Output out = new Hessian2Output(bos);
out.startMessage();
ProdutoTO prod = new ProdutoTO();
prod.setCodigo(1);
prod.setDescricao("prod palhaco");
out.completeMessage();
out.close();
return bos.toByteArray();
}
Client (J2me - CDC):
String url =
"http://localhost:8084/br.com.rosaFlores.WebService/test";;
HttpConnection c = (HttpConnection) Connector.open(url);
c.setRequestMethod(HttpConnection.POST);
OutputStream os = c.openOutputStream();
MicroHessianOutput out = new MicroHessianOutput(os);
out.startCall("returnTO");
out.completeCall();
os.flush();
InputStream is = c.openInputStream();
MicroHessianInput in = new MicroHessianInput(is);
in.startReply();
//int total = in.readInt();
//String ok = in.readString();
Object obj = in.readObject(null);
