SQL Server 2005 - Cannot rollback nested transaction

Sometimes I get the following from SQL Server 2005 when executing a stored procedure:

Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Cannot roll back T1. No transaction or savepoint of that name was found.
    at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDatabaseError(Unknown Source)

Any ideas?

When the connection pooling mechanism attempts to close the prepared statement:

The stored procedure contains a nested transaction T1 which I believe is unnecessary. Could that be the problem?

Thanks

The first error is due to the fact that you have a named nested transaction that you are trying to rollback to - naming a nested transaction (naming means typing something like "BEGIN TRANSACTION ", which in your case = T1) is allowed, but rolling back to a named nested transaction is not supported and results in an error.

See this topic for more information.

If you must rollback nested transaction, you can use SAVE Transaction. see here
