Hi,

We deployed a sample application in JBOSS to insert data & get data from the database.

There are to methods insert and get

In each method we are opening a session using

HibernateUtil.currentSession() and closing as
session.close() and HibernateUtil.closeSession()

First time executing fine, but when I execute the application in another browser ( that means two clients),

I am getting the following error.

Can you suggest what is the wrong?

Thanks,
Srinivas

Is HibernateUtil storing Session on a per-session basis or a per-application basis? I can imagine this happenign if its per-application basis as you have already closed the session after the first client has completed its operation. You should use the session-per-request ideally for web based applications. Refer to the wiki and hib_docs for configuring a session per session/request/application

Hi Thank you

Can you provide teh link where we can get this information

to open session per session/request/application for web based applications

Thanks,
Srinivas
