Re: Connection is closed. Operation is not permitted. ------HELP....

Dave,
 It is totally not expectable. Exception location is random and I am unable track that. When i am trying to delete bulk of data which includes hundreds of delete queries and will be executed sequentially. In the middle of execution of these queries the exception occurring and also when i am trying to cache (read) the data.
Do you think is there any driver and JDK mismatch?

Regards,
Darwin

Hi,

Show me the code before the exception occurs. So far this looks good.
