Problem getting sessions from sessions.xml

Question

I have been having difficulty getting a sessions.xml file deployed on our web application. I've found that if the file is not on the classpath, I do get an error indicating that the sessions.xml or Toplink properties file can not be found. But when I put the sessions.xml in the classpath and have checked to ensure that the projects referenced by the file are also in the classpath, I no longer get the error but for some reason sessions don't get populated by the SessionsManager. I've tried the code below both from within the webapp and also just from a main method in my IDE:
     SessionManager manager = SessionManager.getManager();      
     Hashtable sessions = manager.getSessions();
     System.out.println(sessions.size());
And when I run it I get 0 as my answer. Is there anything more I need to do than set the sessions.xml as well as the projects (we're using compiled Java classes) in the classpath?
Thanks in advance,
Mark

Answer 1

Ok, since the sessions are loaded lazily, I changed my code to the following below, but am now getting null when I specifically ask for 'ODSSession' in the code below.
SessionManager manager = SessionManager.getManager();
Session session = manager.getSession("ODSSession");
System.out.println("session = " + session);
Also, below is my sessions.xml with the database and login information changed for privacy purposes. The sessions.xml was setup using the workbench and I was able to map tables to the project using it. Am I missing something as to why I can't load the session?
Thanks,
