use OpenSessionInViewFilter/Interceptor or the HibernateInterceptor to keep a Hibernate session open during a request
Please notice the difference between the load() and get() method. The load method ( you are using probably ) may return a proxy, so you cannot access to the nested properties.
LazyLoad = false <- Worst practice ever Get or Load with Spring <- Bad practice Solution: Use the OpenSessionInViewFilter as said before. OR Use criteria.fetchMode/hsql fetch within the session you\'re using.
<class name=\"com.cap.hibernate.Employee\" table=\"Employee\" lazy=\"false\">
There an be two solutions: 1] whichever object creating this problem,Use HibernateTemplate.initialize(object name) 2]Use lazy=false in your hbm files
If using hibernateTemplate, this can be avoided by using get instead of load
@ManyToMany(fetch=FetchType.EAGER) if you are using anotation onetoone onetomany write fethch type default lazy=true. It gives the same result given solutations above. Another point check your <prop key=\"hibernate.max_fetch_depth\">5</prop> <prop key=\"hibernate.default_batch_fetch_size\">16</prop> <prop key=\"hibernate.jdbc.batch_size\">25</prop> <prop key=\"hibernate.jdbc.fetch_size\">8</prop> parameters in your mapping files. But pay attention if you give big numbers this will make a bad affect in your project performance.
what the hell solution, this all peoples provide

Answer 19 works for me, try this in your web.xml
<!-- Include this if you are using Hibernate -->
<filter>
<filter-name>Spring OpenSessionInViewFilter</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>
Adding lazy=\"false\" will solve the problem, but as it will lead to loading of collection sat the startup,the appplication will be slow
use lazy= false in hibernate mapping file. check : http://java-masters.blogspot.com
Answer 16!!! I have found a session.clear() in my code. After that call no properties could be loaded lasily any more.
use org.hibernate.Hibernate.intialize();
Hej, I had this problem and I think I solved it, or at least identified some kind of problem with my code. My idea was something like this:
public static Object getData(Object object, Long id){
Object obj = new Object();
Session session = HibernateUtil.getSessionFactory().openSession();
if(object instanceof Incident){
obj = (Incident)(session.load(Incident.class, id));
System.out.println(\"Innuti objec instanceof incident\");
}
System.out.println(\"Komej in till Innuti objec instanceof incident\");
session.close();
HibernateUtil.shutdown();
return obj;
}
The Incident was going to be returned and used while continuing updating the data before a session.flush in the calling method. It crashes when trying to close the session. I am not sure why, but the effect it would have if it was possible, I assume, is that it wouldn\'t be possible to use the incident object since it is retreiving the data from the database while using it. I think...! What I cannot understand is why the error isn\'t thrown when trying to access the data. Perhaps the application is smart enought to predict the usage, or I have multiple errors...
Hope it helps, and if it doesn...it would have helped me :)
I got this problem in the following scenario: I had retrieved a persistent object A, which contained references to persist object B, which in turn contained references to persistent object C. Could reference A and B no problem, but because of the lazy initialising, trying to read from B to C caused this error. The solution was to re-obtain B locally, forcing C to be pulled into scope.
This was giving error getHibernateTemplate().load(Airline.class, code); I changed to get and it worked. getHibernateTemplate().get(Airline.class, code);
make it a transactional unit of work. why need to make Lazy = false, you just remove one of the benefits of using Hibernate... RMA
This can also be caused by clearing your (JPA) persistence context and then trying to access the lazily-loaded attributes. (You\'d need to defer the clearing of the context until after you\'ve finished with the persisted objects.)
I put in all my hbm files lazy to false. But, now, i am wondering, \"why provide a lazy attribute that works only with false\" !!!
Answer 12 works perfect!, putting the attribute to lazy also works, but the system performance will get slow
use Spring\'s OpenSessionInViewFilter:
<filter>
<filter-name>hibernateFilter</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>hibernateFilter</filter-name>
<url-pattern>/spring/*</url-pattern>
</filter-mapping>
You might also need to reattach your object to Hibernate.
answer 22: +1 (in my case, using spring+stripes) reason: allow for lazy loading in web views despite the original transactions already being completed.
lazy load - i did nto try, obviously not a good solution. web.xml - didn\'t work for me. My scenario is having master-detail relationship of a table referring to itself. I have one special record that has a foreign key that don\'t exist. I had to make a work around here: On rename of a record, works as usual, but on adding a new record that refers to my special record as its master, i need to force update() on the master first, before calling saveOrUpdate(). I use, spring2, hibernate3, java6
