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

Question

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

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>

Finally, the full stack-trace from Wildfly:

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;
    }
}

It's hard to help you, because every occurrence of your JNDI / Datasource / Persistence Unit name is different and always changing (e.g. our_app_name, app_name_here or our_app_name_here-core) Please consolidate it. — zforgo, Nov 22 '19 at 09:48
So true, I'm sorry. Thanks for taking a look at it. I edited the question to make it consistent, and I added a bit more info — teleco, Nov 25 '19 at 08:03
Did you set the application path like so @ApplicationPath("foobar") ? — Toastor, Nov 25 '19 at 08:20

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