Hi.

Im having problems with NuSoap timing out if the returned value(of type xsd:string) is bigger than X bytes. It is definitely not an issue with slow execution. There seems to be a spot where it goes from working well to just hanging. Any ideas what could cause this?

Code:

2008-02-25 14:24:57.463890 soap_transport_http: set response timeout to 30
2008-02-25 14:24:57.464019 soap_transport_http: socket connected

it waited for 1 minute and returned timeout. You may want to check your firewall or URL.

This only happens with a certain amount of bytes though, and if less bytes are sent then everything works very fast (same service, same URL etc). Wouldn't that exclude problems related to the firewall and URL?

then you may want to check your server if it can response within timeout you specified.

for testing I generate a random string of X bytes. when I return a string of 15275 bytes everything works okay, but when I return a string of 15276 bytes the call times out. the service returns immediately(by looking at apache logs), so it seems like a client side problem. could this be related to a "chunk size" of 16K ?

if it returns immediately, the problem is definitely on the server. Do you use nusoap on both server and client sides or only on the client?

I use nusoap on both server and client. the service doesnt time out, but the client does.

so you need to inspect nusoap log on the server to check why nothing is sent to the client

When testing with soapUI, the service returns expected data within reasonable time.. this would suggest that there is nothing wrong with the server side, right?

Do you know of any limits that could cause this problem? We notice several other users asking the same question in this and other forums.. we haven't seen anyone get a good answer yet

I'd highly appreciate if you post a sample that will demonstarate the problem.
and no, I do now know any limitations like that. You can check this yourself, nusoap is opensource.

Sample server(from the hello world example):

Code:

<?php
// Pull in the NuSOAP code
require_once('../classes/nusoap/nusoap.php');
// Create the server instance
$server = new soap_server;
// Register the method to expose
$server->register('hello');
// Define the method as a PHP function
function hello($name) {
$str = '';
//generate random string with X bytes
for($i = 0; $i < 15242; $i++) $str .= chr(65 + rand(0, 30));
return $str;
}
// Use the request to (try to) invoke the service
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
$server->service($HTTP_RAW_POST_DATA);
?>

Sample client:

Code:

<?php
// Pull in the NuSOAP code
require_once('../classes/nusoap/nusoap.php');
// Create the client instance
$client = new soapclient('test_server.php');
// Call the SOAP method
$result = $client->call('hello', array('name' => 'Scott'));
// Display the result
print_r($result);
?>

A string length of 15241 works, but when I change it to 15242 it times out.

Your sample works fine. It must be something wrong with your firewall. Check on a clean machine.
