there are no active connections from the application
what am i doing wrong?
It not possible to tell from what you've said. There isn't a common reason why
this might happen.
Do you have a complete, minimal example?
Did anything happen earlier like an exception?
Does it happen always or occasionally?
What version of Jena is this?
What operation system are you running on?
What version of java? Which JDK?
andy
Thanks
