Upgrade to Wildfly 17, can't find persistence unit -------------------------------------------------- Key: WFLY-12806 URL: https://issues.jboss.org/browse/WFLY-12806 Project: WildFly Issue Type: Bug Reporter: Emilio Cuberos Assignee: Brian Stansberry Priority: Major Attachments: persistence.xml Hi, Could you give us some advice? We upgraded from Java 8 / Wildfly 10, to Java 11 and Wildfly 17. Now the persistence units (attached persistence.xml) are no longer found: {code:java} Caused by: java.lang.IllegalArgumentException: WFLYWELD0037: Error injecting persistence unit into CDI managed bean. Can't find a persistence unit named (persistene_unit_name_here) in (war_file_name_here).war for injection point private javax.persistence.EntityManager com.hemocue.cloud.repository.UserProfileRepository.em"}} {code} Here is an example of class where we inject a persistence-unit which is present in the persistence.xml: {code:java} @Dependent public class ProgramRepository extends AbstractRepository<Program> { @PersistenceContext(unitName = "persistene_unit_name_here") private EntityManager em; @Override EntityManager entityManager() { return em; } } {code}
