[Jython-users] asynchronous callback and threads

[Silvio A. <sar...@mo...>]

Hello everybody, again on asynchronous callback.
I am interacting with the Java API of a CORBA server. Some operations 
cannot return an immediate result, and so if I want to know the result of 
the operation I have to register a callback object (that must implement an 
interface provided with the API) to be called asynchronously from the API 
when the operation is completed.
I corrected some bugs (I forgot the self attribute, argh!) and now my 
asynchronous callback object works, but I have a strange output message 
from Jython.

My code is just like this:

# implementation of ReportReceiver interface
class getReport(ReportReceiver):
     def __init__(self,):
         self.received=threading.Event()  # event to notify that report has 
been received

     def receiveReport(...):  # callback method called by the API
	...
         self.received.set()
         return

#main program
# register to get the report
receiver=getReport()
registerForReports(receiver)

# call a CORBA operation
...

# and then wait until the report is received
receiver.received.wait()
unregisterForReports()


When i execute it it works fine, but Jython prints the following message on 
standard output:
currentThread(): no current thread for 2006345

(ok, the number can be any:))
it writes this message just after the receiveReport method sets its 
received event.
What is the reason for this message and what does it mean?

ciao,
Silvio.
