Wildfly can't find persistence units to inject into CDI managed bean

[emiliocuberos]

I have an app working well in Java 8 and Wildfly 10. The driver for the Postgres database is the PostgreSQL JDBC Driver 42.2.8

But after updating to Java 11 and Wildfly 17, the different persistence units from the persistence.xml are no longer found. The message is:

     Caused by: java.lang.IllegalArgumentException: WFLYWELD0037: Error injecting persistence unit into CDI managed bean. Can't find a persistence unit named 'my-persistence-unit' in demo-app.war for injection point private javax.persistence.EntityManager ProgramRepository.em

Here is the definition of one the persistence-units at persistence.xml:

    <persistence-unit name="my-persistence-unit" transaction-type="JTA">

        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>

        <jta-data-source>java:/jboss/datasources/my_datasource</jta-data-source>

        <class>com.demo-app.cloud.entity.config.CopyTextConfig</class>

        <class>com.demo-app.cloud.entity.config.SystemConfig</class>

        <exclude-unlisted-classes>true</exclude-unlisted-classes>

        <shared-cache-mode>ENABLE_SELECTIVE</shared-cache-mode>

        <properties>

            <property name="javax.persistence.schema-generation.database.action" value="none"/>

        </properties>

    </persistence-unit>

This is a class where a persistence-unit is injected, using the PersistenceContext annotation. The class 'Program' maps a table in the database with help of the annotation @Entity and @Table:

    @Dependent

    public class ProgramRepository extends AbstractRepository<Program> {

        @PersistenceContext(unitName = "my-persistence-unit")

        private EntityManager em;

        @Override

        EntityManager entityManager() {

            return em;

        }

Here is the datasource from Wildfly's standalone.xml

        <datasources>

            <datasource jndi-name="java:jboss/datasources/my_datasource" pool-name="my_datasource">

                <connection-url>jdbc:postgresql://localhost:5432/my_database</connection-url>

                <driver-class>org.postgresql.Driver</driver-class>

                <driver>postgresql-42.2.8.jar</driver>

                <security>

                    <user-name>xxxx</user-name>

                    <password>xxxx</password>

                </security>

                <validation>

                    <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.postgres.PostgreSQLValidConnectionChecker"/>

                    <background-validation>true</background-validation>

                    <exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.postgres.PostgreSQLExceptionSorter"/>

                </validation>

            </datasource>

            <drivers>

                <driver name="h2" module="com.h2database.h2">

                    <xa-datasource-class&gt;org.h2.jdbcx.JdbcDataSource</xa-datasource-class&gt;

                </driver>

            </drivers>

        </datasources>

The stack-trace complains about the 'ApiResource' class, which looks like this:

    @Path("birds")

    public class ApiResource {

        @GET

        public Response check() {

            return Response.ok().build();

        }

    }

See @ApplicationPath here:

    @ApplicationPath("api")

    public class ApplicationConfig extends Application {

        @Override

        public Set<Class<?>> getClasses() {

            final Set<Class<?>> classes = new HashSet<>();

            classes.add(ApiResource.class);

            return classes;

        }

    }

Finally, the full stack-trace from Wildfly:

Finally, the fix was to include the persistence.xml file at WEB-INF/classes/META-INF/persistence.xml
