hi every one
this is my project environment
jboss seam: 2.1.0.A1
jboss server:4.2.2.GA
I my page I display the huge amount of data displayed in the form of table.
I fetch those data by using EJP 3 by using PersistenceContext.
When more than one person try to access that particular page at a time
I got following exception
