问题
I want to pass a metamodel attribute of a JPA entity as a parameter to the remote interface of a session bean. As you know, type of this object is javax.persistence.metamodel.SingularAttribute. I was using Hibernate previously and there was no problem, but now with EclipseLink, metamodel attributes is not Serializable. It seems that EclipseLink populate attributes with not serializable objects. Why?
I am using Glassfish 3.1.2.2 and my project dependencies are as below:
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>eclipselink</artifactId>
<version>2.3.2</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>javax.persistence</artifactId>
<version>2.0.3</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>org.eclipse.persistence.jpa.modelgen.processor</artifactId>
<version>2.3.2</version>
<scope>provided</scope>
</dependency>
and the exception stack trace is:
