Axis2 Stub Creation

[Balachandran, Suresh (c)]

I am using the axis 2 to communicate with the third party webservices. This 
webservice is going to be invoked in a timer for every 1 minute and the timer 
is going to run for several days. Now my question is whether we need to create 
the stub object everytime we make the webservice call or can we maintain the 
stub object in the class level variable (timer object) and use the same object 
all the time.

Will a axis fault exception make any changes to the stub. i mean do we need to 
create a new stub instance when a axis fault exception (like timout, server 
down) happens?

is the stub.cleanup alone is enough? or do we need to call the transport 
cleanup as well?

My code

Public void method() {

try {
  stub = new PartnerAPIStub(configurationContext, endPointRef);

   ... service call code

 }
 catch(Exception ex)
 {
      stub.cleanup();
     stub = new PartnerAPIStub(configurationContext, endPointRef);
 }
}

Thanks
Suresh
