I have a login MVC, where in my model User.java I have 2 methods that are not working correctly:
1-create method creates a new user in database, but servlet still redirects me to "operation failed" page
2-update method shows this when deployed:
java.lang.RuntimeException: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SELECT userId FROM user WHERE username='oksana' AND password ='oksana'' at line
Can somebody please help me to understand what I am doing wrong here.
