    JPA entity classes residing in a Wildfly module are not scanned

    Marcos Antonio Novice

      I have some JPA entity classes residing in a Wildfly module. Although there are entity classes in this module, there's no JPA deployment descriptor (persistence.xml file) in the module. Here's the complete path of the module:

       

      {Wildfly_installation}/modules/system/layers/base/br/edu/ufca/main/ufca.jar


      The module descriptor (located in the same folder):


      <?xml version="1.0" encoding="UTF-8"?>

      <module xmlns="urn:jboss:module:1.3" name="br.edu.ufca">

        <resources>

        <resource-root path="ufca.jar"/>

        </resources>

        <dependencies>

        <module name="javax.faces.api"/>

        </dependencies>

      </module>


      Now I have a web application where I declare the dependency on this module in META-INF\MANIFEST.MF:


      Manifest-Version: 1.0

      Class-Path:

      Dependencies: br.edu.ufca export


      I also have, in the web application, the persistence.xml file where I list some entity classes that are located in the ufca.jar module:


      <?xml version="1.0" encoding="UTF-8"?>
      <persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd" version="2.1">
      <persistence-unit name="criacao-email">
        <jta-data-source>java:jboss/datasources/CriacaoEmailDS</jta-data-source>

       

        <class>br.edu.ufca.modelo.Setor</class>

        <!-- more classes -->

       

      </persistence-unit>
      </persistence>


      The problem is that when I run the web application executing code that tries to load some entity classes using an EntityManager, for example, I get exceptions like this:


      Caused by: java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: Setor is not mapped [SELECT s FROM Setor s ORDER BY s.nome]

      which clearly shows that the JPA provider didn't scan the entity classes. But if I access from the web application any class from the Wildfly module without using JPA, I have success, which shows that the module is really in the classpath of the application.

       

      Is this default behaviour or what am I doing wrong?

       

      Thank you in advance.
