hi to all,

i am new to this topic ,
i am developing an application using jboss seam framework.
i need to develop optimistic lock in my application to restrict end user from concurrency updations of entity objects.
while i am googling i got information that @version annotation is useful for this . but i don't know how do i use this @version annotation in entity beans.

so can any one help me in this with some code examples related to this?

thanks in advance for your help...
