@Inheritance and LAZY / EAGER FetchType.
I've got the following entity's:
Entity JObject:
@Entity
@Table(name = "object")
@NamedQueries(
{
@NamedQuery(name="jobject.findEager",
queryString="SELECT j FROM JObject AS j" +
" LEFT JOIN FETCH j.JAnnotations " +
" WHERE j.name = :objectName AND j.JPackage.name = :packageName")
}
)
@Inheritance(strategy = InheritanceType.SINGLE_TABLE,
discriminatorType = DiscriminatorType.STRING)
@DiscriminatorColumn(name = "objectType")
public class JObject extends EntityBase implements java.io.Serializable {
private Collection<JAnnotation> jAnnotations = null;
public JObject() {
}
@ManyToMany(fetch = FetchType.LAZY, cascade={CascadeType.ALL})
@JoinTable(
table=@Table(name="object_annotation"),
joinColumns=@JoinColumn(name="objectKey", referencedColumnName="id"),
inverseJoinColumns=@JoinColumn(name="annotationKey", referencedColumnName="id"))
public Collection<JAnnotation> getJAnnotations() {
return jAnnotations;
}
public void setJAnnotations(Collection<JAnnotation> jAnnotations) {
this.jAnnotations = jAnnotations;
}
}
And the entity JClass:
@Entity
@NamedQueries(
{
@NamedQuery(name="jclass.findEager",
queryString="SELECT j FROM JClass AS j" +
" LEFT JOIN FETCH j.JAnnotations " +
" LEFT JOIN FETCH j.InnerClasses " +
" WHERE j.name = :className AND j.JPackage.name = :packageName")
}
)
@Inheritance(strategy = InheritanceType.SINGLE_TABLE,
discriminatorType = DiscriminatorType.STRING, discriminatorValue = "class")
public class JClass extends JObject implements java.io.Serializable {
private Collection<JClass> innerClasses = null;
public JClass() {
}
@ManyToMany(fetch=FetchType.LAZY, cascade = {CascadeType.ALL})
@JoinTable(
table=@Table(name="outerclass_innerclass"),
joinColumns=@JoinColumn(name="outerClassKey", referencedColumnName="id"),
inverseJoinColumns=@JoinColumn(name="innerClassKey", referencedColumnName="id")
)
public Collection<JClass> getInnerClasses() {
return innerClasses;
}
public void setInnerClasses(Collection<JClass> innerClasses) {
this.innerClasses = innerClasses;
}
}
If i deploy these entity's JBoss is complaining about the named query: jclass.findEager
could not resolve property: InnerClasses of: com.jinstance.javalibrary.j2ee.ejb.JClass [SELECT j FROM com.jinstance.javalibrary.j2ee.ejb.JClass AS j LEFT JOIN FETCH j.JAnnotations LEFT JOIN FETCH j.JFields LEFT JOIN FETCH j.JOperators LEFT JOIN FETCH j.InnerClasses WHERE j.name = :className AND j.JPackage.name = :packageName]
But as you can see this property does excist.
If i disable the LEFT JOIN FETCH j.InnerClasses then the deployment succeeds without any problem.
Why do i get this error message?
Environment:
JBoss 4.02
EJB3 Beta
