I am facing exceptions when I try to use JTA from within Hibernate. My source code is as follows:-

static {
try
{
cfg = new Configuration();
cfg.setProperty("hibernate.dialect", "net.sf.hibernate.dialect.OracleDialect");
cfg.setProperty("hibernate.cglib.use_reflection_optimizer", "true");

cfg.setProperty(
"hibernate.transaction.manager_lookup_class",
"net.sf.hibernate.transaction.WeblogicTransactionManagerLookup");
cfg.setProperty(
"hibernate.transaction.factory_class",
"net.sf.hibernate.transaction.JTATransactionFactory");

}

------------------------
However, when the class loads I get the following exception stacktrace for the transaction related properties being set. wHY IS THE EXCEPTION OCCURRING?:-
