The class reload is not the problem here.
Your data (HT) will be lost between requests unless you can store it in the
session object.
HT needs to be Serializable for this to work.
You can then do session.putValue("somekey", HT);
to store it.
HTClass HT = (HTClass)session.getValue("somekey");
gets it back for you.
Hope that helps
