Hi,
I am working on Spring -hibernate and unable to resolve concurrency in my web application.
Basically while i try to upload files in 2 sessions i am getting the error
org.springframework.transaction.IllegalTransactionStateException: Pre-bound JDBC Connection found - HibernateTransactionManager does not support running within DataSourceTransactionManager if told to manage the DataSource itself. It is recommended to use a single HibernateTransactionManager for all transactions on a single DataSource, no matter whether


My program basically invokes the database updates through hibernate using hibernate transactions.therefore when i am trying to concurrently upload more than one file there seems to be conflict with the transaction management.

Can any one please help.

Regards
Srikrishna
 
It is sorta covered in the JavaRanch Style Guide.
