I created a project with JHipster, but made changes and added stuff to it. It runs ok when ran as a Spring Boot project from the IDE (Intellij), but when trying to build a WAR and deploy it on a Tomcat 7, it fails with the following stack trace:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager' defined in class path resource [org/springframework/boot/autoconfigure/transaction/jta/JndiJtaConfiguration.class]: Invocation of init method failed; nested exception is java.lang.IllegalStateException: No JTA UserTransaction available - specify either 'userTransaction' or 'userTransactionName' or 'transactionManager' or 'transactionManagerName'

I also tried:

mvn -Pprod clean package

but that also fails with:

Aborted due to warnings.

I have added the Google GeoChart, and that seems to cause an issue.

What I would like to get is a classic WAR that I can deploy on Tomcat, but I am obviously doing something wrong and I don't know what.

Thank you.
