I have this PHP program:

<?php
echo 'Start of Soap Request<br />';
$client = new SoapClient("http://192.168.201.67:10010/web/services/getItemDesc?wsdl");
print_r($client);
echo '<br />Start of Var_Dump<br />';
var_dump($client);
echo '<br />Result Print<br />';
$result = $client->testws(array("PEITEM" => "1020000000", "PEMSG" =>" "));
print_r($result);

?>

That access a web service on my iSeries. I can get the Web Service to work in SOAP UI, but for some reason it does not work when called from this very short program. I seem to be missing something. I have tried to look at the error logs on the iSeries, but all I have been able to find is a Null Pointer Error:

Here is the WSDL that was generated by the iSeries. Again it works when testing with SOAPUI so hopefully it is an option or something I can use on the SoapClient instantiation.

If you made it this far, thanks for looking.

Hello svilla,

at least there is nothing obvious. First of all, I would try to omit the second argument. Unfortunatly a "Null pointer exception" in the Java stack dump is not giving a real hint.

In a second step you might want to consider adding some options to the SOAPClient constructor (like SOAP version or encoding, although both of them are unlikely to solve the problem).

In a third step I would try the whole thing in NON-WSDL mode. Just put the plain URL into the attributes of parameter 2 of the constructor and put Null into parameter 1.
