Hi,
I can resolve my problem. I 'm use JSON in twow parts (server and client(J2ME)).
I just use Hessian to return the String..
Follow the code
Hessian Server:
public String downloadProdutos() throws Exception {
List ret = ProdutoBO.getInstance().findAllProduto();
// JSON return
JSONArray jsonArray = new JSONArray();
if (ret.size() > 0) {
for(Iterator iter = ret.iterator(); iter.hasNext();) {
Produto prod = (Produto) iter.next();
// create object JSON
JSONObject jsonObj = new JSONObject();
jsonObj.put("codigo", prod.getCodigo());
jsonObj.put("descricao", prod.getDescricao());
jsonObj.put("id", prod.getId());
jsonObj.put("importado", prod.getImportado());
jsonObj.put ("precoCompra", prod.getPrecoCompra());
jsonObj.put("precoVenda", prod.getPrecoVenda());
jsonObj.put("tipoOrigem", prod.getTipoOrigem());
// Add json object to array.
jsonArray.put(jsonObj);
}
// Just return the array from JSON
return jsonArray.toString();
}
else {
return "";
}
}
------------------------------
--------------------------
Code in the client (Pocket PC - J2ME/CDC)
public void showPage(String pageName, Thinlet thinlet) {
Object senha = thinlet.find("txtSenha");
try {
// Call web Service Hessian
String url =
"http://192.168.0.101:8080/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("downloadProdutos");
out.completeCall();
os.flush();
// Begining read return
InputStream is = c.openInputStream();
MicroHessianInput in = new MicroHessianInput(is);
in.startReply();
// Get return JSON from Hessian
String respJSON = in.readString();
// Close Web Service read
in.completeReply();
// Deserialize JSON -> POJO
JSONArray jsonArray = new JSONArray(respJSON);
for(int item = 0; item < jsonArray.length(); item++) {
// Get JsonObject
JSONObject jsonObj = jsonArray.optJSONObject(item);
// JSON -> POJO
Produto prod = new Produto();
prod.setCodigo(jsonObj.getString("codigo"));
prod.setDescricao(jsonObj.getString ("descricao"));
prod.setId(Integer.valueOf(jsonObj.getInt("id")));
prod.setImportado(Boolean.valueOf(jsonObj.getString("importado")));
prod.setPrecoCompra(BigDecimal.valueOf(jsonObj.getLong("precoCompra")));
prod.setPrecoVenda(BigDecimal.valueOf(jsonObj.getLong("precoVenda")));
prod.setTipoOrigem (jsonObj.getString("tipoOrigem"));
}
thinlet.setString(senha, "text", "sucess: " +
jsonArray.length());
} catch (Exception ex) {
thinlet.setString(senha, "text", "ex: " + ex.getMessage ());
}
}
