Hi
I am facing problem if I specify fetchType as lazy
I have made the following entry in web.xml
<filter>
<filter-name>lazyLoadingFilter</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFi
lter</filter-class>
</filter>
And following in my model
@ManyToMany(fetch = FetchType.EAGER)
@JoinTable(
name="user_roles",
joinColumns = { @JoinColumn( name="user_id") },
inverseJoinColumns = @JoinColumn( name="role_id")
)
public Set<Role> getRoles() {
return roles;
}
org.hibernate.LazyInitializationException: failed to lazily initialize a
collection of role: com.mps.stats.model.User.roles, no session or session
was closed
