    Re: EJB Transactions

    If I am not mistaken, EJB1.1 specs say that the trasaction won't be rolled back automatically.

    Re: avoid DOS window

    If you don't want DOS window when you run your application, use 'javaw.exe' for JDK1.2 or 'jre.exe' for JDK1.1

    Hope this is what you want.
