I’m using Java, JPA, Primefaces, Wildfly and Mysql, not much to do, but it’s good to inform.

I fill in all the fields, all right the check is performed. When I click save the success message is displayed but nothing is saved in the bank, someone can help me identify where the error is?

I have my xhtml page:

  • The problem may be occurring in the mapping of the entityManager( persistence.xml ), give a look at what’s on this link: http://www.tutorialspoint.com/ejb/ejb_persistence.htm

I don’t work with JPA, but because of the description you gave of the behavior and your saving method. I think a commit is missing. If your connection is set to setAutoCommit(false). You have to commit at the end of the run. a look here, explains what the commit procedure with jpa http://www.java2s.com/Code/Java/JPA/StartTransactionandCommit.htm

  • Jeterson, I performed the procedure and continues in the same way!
