java - Application does not work in an other system -

-

i wrote javafx application in netbeans using jdk8, uses derby.

the built project runs well, fine @ first computer. if run "dist" library working properly.

but when took mother's pc (same operation system - windows 7) 32 bit jre, , installed jdk program runs well, cannot communicate database.

i can't create new records, can't read database wasn't.

do need install apache derby mother's computer? wouldn't think so, since using local derby database. (the filesystem same, database folder can found @ dist folder, should work.)

there no error message, not should. (for example not list records database @ main screen)

what wrong?
