Hello,
I'm developing a web application using the hibernate framework.
When I realod my managed bean, automatically it execute the constructor of this bean. In this constructor I need to get data from database. so I make call on it. The table contains about 8000 items.
When I reload many times my bean, I have this exception :
Code:
java.lang.OutOfMemoryError: Java heap space

This is the request
Code:
session.createQuery("from Tblorder where order_brokerid = '" + str+ "' order by (order_id)").list();
It gets 8000 items. In every relaod I called this request 3 times (for certain reason). In the third call the exception appear.
Note that in the second call the execution time of the request is 4938ms which is I think very strong for just 8000 items !!!
thanks for your help
