Hi,
We are using toplink, EJB and ADF for our requirement. We are using SessionFactory to get server session and perform transactions using UnitOfWork. We have sessions.xml which looks below:
<?xml version = '1.0' encoding = 'UTF-8'?>
<!DOCTYPE toplink-configuration PUBLIC "-//Oracle Corp.//DTD TopLink Sessions 9.0.4//EN" "sessions_9_0_4.dtd">
<toplink-configuration>
<session>
<name>default</name>
<project-xml>META-INF/Map.xml</project-xml>
<session-type>
<server-session/>
</session-type>
<login>
<datasource>jdbc/xxxDS</datasource>
<sequence-preallocation-size>1</sequence-preallocation-size>
<uses-external-connection-pool>true</uses-external-connection-pool>
</login>
</session>
</toplink-configuration>
When we deploy in Server, sometimes we are getting the below exceptions. and after sometime its getting hanged.
[TopLink Info]: 2013.03.05 10:35:28.656--ServerSession(29522364)--default login successful
[TopLink Info]: 2013.03.05 10:35:28.657--ServerSession(29522364)--default logout successful

Could anyone throws some light on this, why this is happening and resolutions for the same?
Thanks & Regards,
