How to perform backup and restore operations using hibernate?

Iam using SQLServer 2005 database

I have tried it this way, but iam getting the following exception
Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Cannot perform a backup or restore operation within a transaction.

Query:
String backupQuery="BACKUP DATABASE jiffy TO disk=?";
tx =session.beginTransaction();

SQLQuery selectQuery=session.createSQLQuery(backupQuery);
selectQuery.setString(0, path);
selectQuery.executeUpdate();

tx.commit();

I have did the same for Restore
Iam getting the following exception
Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: RESTORE cannot process database 'attendance' because it is in use by this session. It is recommended that the master database be used when performing this operation.
