im using netbeans to create a simple “rental car system” where i will create multipl java frames using swing and connect those to my database – im using sqlite studio- ive downloaded the jdbc jar,created the database that has a login table and a carlist table , i followed the steps to connect the database with the java file and finally designed the Jframes , the ploblem is that the login page works just fine but when i try to register a new user the data just wont get registred in the database for some reason..
