I tried a few things today but beside more problems, no solution yet.
1. Created a few POJOs and added a bunch of JPA annotations to them
(including the javax.persistence.CascadeType). In my RPC service
class, I manually instantiate a POJO and return it. This works fine.
The GWT compiler/shell is not complaining about any annotations. I'm
still using Gilead and GWT-SL with the -noserver option.
2. For my second attempt, I configured the above POJOs in my Spring
AnnotationSessionFactoryBean, e.g
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource"><ref bean="dataSource"/></property>
...
<property name="annotatedClasses">
<list>
...
<value>au.gov.vic.dpi.mpd.geodatavic2.module.domain.client.model.security.User</
value>
</list>
</property>
</bean>
Note, I still just manually create the User class in the RPC service
class, I'm not actually retrieving anything from database via
Hibernate but it didn't work. I got the following exception (on the
server):

I'm still scratching my head about this one...
3. I did try to retrieve POJOs from the database instead of manually
creating them but I got the same result.
The POJOs are quite simple. Here's an example. Why this doesn't work
is a mistery to me.
@Entity
@Table(name = "USERS", schema = "SECURITY")
public class Users extends LightEntity implements java.io.Serializable
{
private String userId;
private Date endDate;
private Set<ApplicationRoles> applicationRoleses = new
HashSet<ApplicationRoles>(0);
public Users() {
}
@Id
@Column(name = "USER_ID", unique = true, nullable = false, length =
25)
public String getUserId() {
return this.userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
@Temporal(TemporalType.DATE)
@Column(name = "END_DATE", length = 7)
public Date getEndDate() {
return this.endDate;
}
public void setEndDate(Date endDate) {
this.endDate = endDate;
}
@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY,
mappedBy = "users")
public Set<ApplicationRoles> getApplicationRoleses() {
return this.applicationRoleses;
}
public void setApplicationRoleses(Set<ApplicationRoles>
applicationRoleses) {
this.applicationRoleses = applicationRoleses;
}
}
