I'm trying to send an array from my jsp to my Servlet via ajax POST request. My array has a few objects with many fields. If I try to send and array with 11 objects - using JSON.stringify - it works OK (the array is received on server-side), but the problem happens when I try to send an array with 12+ objects. The error is: 400 Bad Request
and looking with Google Chrome Debugger, I can find this error: fluxos:(unable to decode value)
where fluxos
is the name of my array.
RELEVANTE PART OF CODE:
for(var i=0; i<numberOfConnections; i++) {
fluxo = criaEstruturaFluxo(i);
fluxos.push(fluxo);
}
$.ajax({
type: "POST",
url: 'Servlet?fluxos='+JSON.stringify(fluxos),
success: function (data) {
alert('success');
}
});
...
function criaEstruturaFluxo(i) {
...
...
var fluxo = {
xOrigem: xOrigem,
yOrigem: yOrigem,
xDestino: xDestino,
yDestino: yDestino,
codWorkflow: codWorkflow,
acaoAvanco: acaoAvanco,
codAtividadeOrigem: codAtividadeOrigem[1],
codAtividadeDestino: codAtividadeDestino[1],
numero: numero,
nomeAtividadeOrigem: nomeAtividadeOrigem,
nomeAtividadeDestino: nomeAtividadeDestino,
codConexao: codConexao,
tipoOrigem: tipoOrigem,
tipoDestino: tipoDestino,
xFluxoOrigem: xFluxoOrigem,
yFluxoOrigem: yFluxoOrigem,
xFluxoDestino: xFluxoDestino,
yFluxoDestino: yFluxoDestino,
deletarArquivo: deletarArquivo,
ultimaConexao: ultimaConexao,
caminhoArquivo: caminhoArquivo,
xTela: xTela,
yTela: yTela
};
return fluxo;
}
My encoded array has 8000+ characters length and because of that, I think it's exceeding the max length a POST request can handle... Is that possible or might be something on the code that I'm sending to my Servlet?

Reset to default 6Your url is very long. In theory that shouldn't cause any problems, but there's a practical limit that depends on the server and proxies that you use. Send the data on the body of the request and not on the url.
Agree with Andres & Luiggi. Here's what your modified code would look like:
$.ajax({
url: "Servlet",
type: "POST",
contentType: "application/json; charset=utf-8",
data: JSON.stringify({ "fluxos": fluxos }),
success: function(data) {
alert("success");
}
});
