Hi people, I'm writing a service (very simple service) in GT4 that does submission of jobs (using java CoG kit abstractions). This servise print in container log one message (the message is the parameters of the method). But when I run a client to test the web service, I don't have sucess...
I saw following error message in globus container log: ------------------------------------8<-------------------------------------------- ...
