22,107 PointsNullPointerException?
Hi all,
I am working on this video: https://teamtreehouse.com/library/hibernate-basics/persisting-data-with-hibernate/saving-data-with-hibernate
When I run the application there seems to be NullPointerException instead of Hibernate: insert into Contact (id, email, firstname, lastname, phone) values (null, ?, ?, ?, ?).
Here is part of my console output:
INFO: HHH000400: Using dialect: org.hibernate.dialect.H2Dialect
Hibernate: drop table Contact if exists
Hibernate: create table Contact (id integer generated by default as identity, email varchar(255), firstname varchar(255), lastname varchar(255), phone bigint, primary key (id))

Any help would be much appreciated, thank you!

2,225 PointsDid you forget to add the java transaction api as dependency in Gradle? The dependency block in your build.gradle file should look similiar to this:
dependencies {
compile 'org.hibernate:hibernate-core:5.1.0.Final'
compile 'com.h2database:h2:1.4.191'
compile 'javax.transaction:jta:1.1'
}

But I can't help without seeing actual project.
If you know/can post a project on GitHub and share a link, will be glad to take a look.
Otherwise, can't help :)
