I am having a simple insertion into the java web database using JPA, Hibernate and Maven. The problem is that error is appearing java.lang.NoClassDefFoundError, and I can’t see where the bug is. Take a look at the Stack Trace below:

  • Put stacktrace as text and complete code (including instruction package) class JPAUtilplease

  • I’ve put on top of a look

  • Enter the class code JPAUtil also please

  • I’ve already put on top

  • Your mistake seems to be in factory = Persistence.createEntityManagerFactory("Teste");, but the error generated ends up being hidden by NoClassDefFoundError. Do the following, replace this line with try { factory = Persistence.createEntityManagerFactory("Teste"); } catch (RuntimeException | Error e) { e.printStackTrace(); throw e; } and say what comes up.

  • @Victorstafusa Face already gives a look there

  • @Ailsondelgado Ah, this shows that there is a problem in the transactions. What’s in your persistence.xml?

  • @Victorstafusa already put the persistence.xml of a look

Remove that line from your persistence.xml:

<jta-data-source>java:jboss/datasources/MySQL-DS</jta-data-source>

You are managing the creation of EntityManager by creating yourself the EntityManagerFactory. However the <jta-data-source> is used in cases where the application container manages the EntityManager.

More information that question in Soen.

  • And the following, the container I’m using is the wildfly and I did the data-source settings on the wildfly standalone and used the persistence.xml file to generate the tables in the database when running the container, if I remove the <jta-data-source>java:jboss/datasources/Mysql-DS</jta-data-source> sera will give problem?
