Hi Deepal,
I found that the cause of NPE is "unassinged parent". If the service is
already registered in axisConfig it doesn't enter in the code that
assings a parent to the service. Also, it doesn't uses the parent of
the registered service.
The code causes NPE is here:
----------------------------------------------------------------
// org.apache.axis2.client.ServiceClient
public ServiceClient(ConfigurationContext configContext,
AxisService axisService) throws AxisFault {
...
// If the service is already registered, it doesn't enter
// here so there will be no parent.
if (this.axisConfig.getService(this.axisService.getName()) == null) {
this.axisConfig.addService(this.axisService);
}
ServiceGroupContext sgc = new ServiceGroupContext(this.configContext,
(AxisServiceGroup) this.axisService.getParent());
this.serviceContext = sgc.getServiceContext(this.axisService);
}
----------------------------------------------------------------
Here is the my way of passing this problem:
----------------------------------------------------------------
// org.apache.axis2.client.ServiceClient
public ServiceClient(ConfigurationContext configContext,
AxisService axisService) throws AxisFault {
...
AxisService service = null;
AxisService registeredService =
this.axisConfig.getService(this.axisService.getName());
if (registeredService != null) {
service = registeredService;
} else {
this.axisConfig.addService(this.axisService);
service = this.axisService;
}
ServiceGroupContext sgc = new ServiceGroupContext(this.configContext,
(AxisServiceGroup) service.getParent());
this.serviceContext = sgc.getServiceContext(service);
}
----------------------------------------------------------------
But I'm still having an exception that says:
----------------------------------------------------------------
