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.
