java - Parametered call of swing instance -


my problem following: have java swing application uses database connection via jpa. startup process slow due authentication onto database. furthermore application, when being closed, has authenticate again when being opened. unsatisfactory.

i thought of workaround swing instance being held in idle instead of being closed. when call occurs, instance opens according parameters. example of ms word ( inital startup slow, when instance running, current instance being overwritten current call instead of creating new instance).

does have idea how work? starting point or tutorial above being shown helpful.
