Description:
------------
I wrote a very simple webservice using Axis2 in Java and deployed it
using Apache Tomcat. The soap service contains just two functions, dummy
and dummy2. Both functions just sleep for a second and then return an
integer (42 and 43).
When I execute the php client code below once, the output is as
expected ($v1 is 42 and $v2 is 43) but when I hit reload before both
calls are finished I only get a return value from the second call
although "__getLastResponse()" returns a valid xml document which
contains the expected result.
It looks like the parsing of the xml response doesn't work correctly
when multiple threads are running.
Strangely this doesn't happen when I call the same method twice (ie.
dummy and then dummy again in the same script) - then I get the same
value in $v1 and $v2.
As __getLastResponse() return the correct xml response I assume this is
a php bug and not an Axis2 bug.
I tried several versions of PHP including 5.1.2.2, 5.2.3 and the latest
snapshot - all with the same result.
Reproduce code:
---------------
<?php
function printResult($result, $soap)
{
print "<pre>\n";
print "Result :\n"; var_dump($result); print "\n";
print "Request :\n".htmlspecialchars($soap->__getLastRequest())
."\n";
print
"Response:\n".htmlspecialchars($soap->__getLastResponse())."\n";
print "</pre><br>";
}
$soap = new
SoapClient('http://127.0.0.1:8080/axis2/services/WebhandlerService?wsdl',
array('trace' => 1));
$v1 = $soap->dummy(array('v' => '4'));
printResult($v1, $soap);
$v2 = $soap->dummy2(array('v' => '5'));
printResult($v2, $soap);
?>
Expected result:
----------------
This is the result I expect and which I get on the first call of the
php script:

int(42)
