    JPADataSource and ManyToMany relationship

    Does JPADataSource support ManyToMany relationship? I could find examples with OneToMany and ManyToOne, but couldn't find example using ManyToMany. Is it supported or I should use SQL DataSource?

    OK, it seems that it is possible to use it in similar way like OneToMany.

    However, I couldn't make it load lazy collection. That is, until I made my ManyToMany collection as FetchType.EAGER I had LazyInitializationException when fetching data source. Am I doing something wrong or it is expected behavior?

      Hi,

      Can you provide with minimal test case?

      Regards,

        Hm, I can post my code (at least parts that I think they are important):

        Role.java
        Code:
        @Entity
@Table(name="es_role")

public class Role implements Serializable {
   	@Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name="id")
    private Long id;

    @Column(name="name", unique=true)
    private String name;
    
    @Column(name="description")
    private String description;
    
    @Column(name="status_id")
    private Integer statusId;
    
    @ManyToMany
    @JoinTable(name="es_role_permission",
           joinColumns=@JoinColumn(name="role_id"),
            inverseJoinColumns=@JoinColumn(name="permission_id"))
    private Set<Permission> permissions;
   
   
   //getters and setters
   ...
}
        Permission.java
        Code:
        @Entity
@Table(name="es_permission")

public class Permission implements Serializable {
 	@Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name="id")
    private Long id;

    @Column(name="name", unique=true)
    private String name;
    
    @Column(name="description")
    private String description;
    
    @Column(name="status_id")
    private Integer statusId;
    
    //getters and setters
    ...
}
        permission.ds.xml

        Code:
        <DataSource  
    ID="permission"  
    serverConstructor="com.isomorphic.jpa.JPA2DataSource"  
    autoDeriveSchema="false"

               multiple="true"
               foreignKey="permission.id"/>
              
	</fields>
   
    
</DataSource>
        RoleListGrid.java
        Code:
        package net.esteh.esdoc.client.panel.admin.role;

import com.smartgwt.client.data.DataSource;
import com.smartgwt.client.widgets.grid.ListGridField;

import net.esteh.esdoc.client.EstehListGrid;

public class RoleListGrid extends EstehListGrid {
	
	public ListGridField nameField = new ListGridField("name");
	public ListGridField descriptionField = new ListGridField("description");
	
	public RoleListGrid() {
		setFields(nameField, descriptionField);
		setDataSource(DataSource.get("role"));
		setAutoFetchData(true);
	}
}

        When data is fetched, list gets data but permissions are not populated (I need that for second list grid). Here is log:

          Hi.

          Strange. EntityManager should be open at the moment of exception.

          Could you set logging to debug for following packages:

          com.isomorphic.jpa
          com.isomorphic.datasource
          com.isomorphic.rpc

          and post server log.

          Regards,
          Alius

              Hi,

              Looks like it is something wrong with your configuration (check settings in your glassfish).

              If you will check log you will see that after execution of select transaction is committed but connection is not closed yet. Then JPADataSource tries to lazily load permissions for every role (fails with exception for every row). At the end of the log you can see line
              Code:
              INFO: === 2012-02-08 08:18:58,289 [0(3)] DEBUG JPADataSource - Releasing entity manager.
              At this moment system releases (closes) EntityManager. Lazy-loading exceptions before this line most probably indicate that EntityManager was closed by container.

              Regards,
              Alius

                Hmm, could this be connected with other problem I have reported:

                  I'm not sure. Here we deal with closed connection (not transaction).
