OFBIZ PHP client - cannot locate service name

[Beula Angeline]

Hi,

I'm trying to run a simple webservice using a php client.
The method I want to run is "searchHelloPerson" but i get
"Request SOAPService caused an error with the following message: Error  
calling event: org.ofbiz.webapp.event.EventHandlerException: Cannot  
locate service by name (helloPersonId) (Cannot locate service by name  
(helloPersonId))"
which is strange since the name of the service is "searchHelloPerson" and  
not "helloPersonId".... 

Thanks.

Regards,
Beula.
