Hi Guys,
I'm using Weblogic Server 6.1 & using Session facade architecture in my
project.
I faced a hazardous problem, which is causing WL to shut down & so it's
fatal.
The problem occurs when a Session Bean (TX: RequiresNew) interacts with
400-500 Entity Beans objects (TX: Supports) to fetch some information.
It might be due to incorrect handling of transactions. Here is the text,
which I took out from log file:
--------------- nested within: ------------------
javax.ejb.EJBException
- with nested exception:
[weblogic.jdbc.mssqlserver4.TdsException: I/O exception while talking to the
server, java.io.IOException: Broken pipe]
