Hi everyone,
I just starting to try using deltaspike.
To begin I create a EAR Project using the tutorial
(https://vaadin.com/wiki/-/wiki/Main/Implementing+Enterprise+Web+applications+with+Vaadin),
and deploying on a Wildfly 10.1 .
This is made of three components:
• Common – where I keep my entities
• Backend – used for the EJB and where I try to use the Deltaspike
• UI – using Vaadin (I think that this is irrelevant for my problem)
On the “Backend”, I add this to my pom.xml:
…
<dependency>
<groupId>org.apache.deltaspike.distribution</groupId>
<artifactId>distributions-bom</artifactId>
<version>1.7.1</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
…
<dependency>
<groupId>org.apache.deltaspike.core</groupId>
<artifactId>deltaspike-core-api</artifactId>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.apache.deltaspike.core</groupId>
<artifactId>deltaspike-core-impl</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.apache.deltaspike.modules</groupId>
<artifactId>deltaspike-data-module-api</artifactId>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.apache.deltaspike.modules</groupId>
<artifactId>deltaspike-data-module-impl</artifactId>
<scope>runtime</scope>
</dependency>
And exposed the entity manager:
public class CdiConfig {
@Produces
@Dependent
@PersistenceContext(unitName = "proto2")
public EntityManager entityManager;
}
Next, I created a simple entity:
@Entity
@Table(name = "customers")
public class Customer {
private String contactPerson;
private String email;
<< Setters and Getters add>>
…
And an generic repository to host common methods:
public interface GenericRepository<T> extends EntityRepository<T, Long> {
public T findById(Long id);
}
Last, I created a specific eepository for the customer entity:
@RequestScoped
@Repository(forEntity = Customer.class)
public interface CustomerRepository extends GenericRepository<Customer> {
public QueryResult<Customer> findByNameLikeIgnoreCase(String filter);
}
The problem is that when I deploy the .ear file, I get this errors:
12:15:30,686 WARN [org.jboss.modules] (MSC service thread 1-3) Failed to
define class org.rna.vaadin.proto2.ejb.dao.GenericRepository in Module

And,

…
For simplicity, I didn’t write here the remaining JPA or project settings.
What am I doing wrong? Or did I missed something?
Thank you in advance
