J2E and multi-threading

I know that multi threading is not permited in J2E applications.

BUT my pb is as following:

My J2E application is using a scheduler (Quartz). This scheduler reads a file witch contains commands to be inserted in database.

If i make a classical loop with a for instruction, the performance are not good...because i need to wait for the insert before inserting a new command.

I woulk like to use a threading mechanism to insert those commands in DB. Why is this solution not correct and what can i do as an alternative (without using MDB) ?
