Hello, I am new to web services and soap. I am using axis2 1.1.1 to load
Spring 2.0 and expose a POJO as a web service. Additionally, I have a
passwordCallbackClass for the rampart wss4j InflowSecurity which
authenticates a username and password via kerberos via JAAS. Here is my
services.xml:
<serviceGroup>
<service name="SpringInitV1" class="myservice.SpringInit">
<description>

<parameter name="ServiceClass">myservice.SpringInit</parameter>
<parameter name="ServiceTCCL">composite</parameter>
<parameter name="load-on-startup">true</parameter>
<operation name="springInit">

</operation>
</service>
<service name="MyService"

<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out";
class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
</messageReceivers>
<module ref="rampart" />
<parameter name="InflowSecurity">
<action>
<items>UsernameToken</items>
<passwordCallbackClass>myservice.MyServiceSecurityManager</passwordCallbackClass>
</action>
</parameter>
</service>
</serviceGroup>
I have a client written in perl (SOAP::Lite) which runs in a loop and
makes requests to one of the methods exposed through the POJO. Here is a
snippet:
my $soap = SOAP::Lite -> uri($uri) -> proxy($proxy) -> outputxml(1);
my $Username = SOAP::Data->name('Username' => $cur_username);
my $Password = SOAP::Data->name('Password' => $cur_password)
->attr({Type =>
'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText'});
my $UsernameToken = SOAP::Data->name('UsernameToken')
->value(\SOAP::Data->value($Username, $Password));
my $security = SOAP::Header->name(Security)
->attr({'xmlns' =>
'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd'})
->value(\$UsernameToken);
$method = SOAP::Data->name('myServiceMethodName')->attr({xmlns =>
'$service_ns'});
my $param1 = SOAP::Data->name('param1')
->value(\SOAP::Data->value($param2, $param3)) ->attr({xmlns =>
'$service_type_ns'});
@param = SOAP::Data->value($param1)->attr({xmlns =>
'$service_ns'});
my $result = $soap->call($security, $method => @param);
The WSDL lists MyServiceSOAP11Binding and MyServiceSOAP11Binding
bindings attached to the endpoint in the web service to which I am
making the request. I'm using soap over an http transport.
It works perfectly in that I get the response I expect for that request.
However, when I launch a parallel second client which loops and makes
calls to a different method in the web service, then the two clients
begin to intermittently receive responses destined to each other.
Apparently, Axis2 is returning the first completed response to the first
client waiting for a response. What am I doing wrong? Is this a
configuration problem in axis2? I want a synchronous request/response
behavior from the web service. Do I need to incorporate WS-Addressing
into the request sent from the client? I was under the impressing that
WS-Addressing was only required to redirect the response to a different
endpoint than the one that made the request.
Thx
