Recebemos esta exception ao executar o cliente abaixo:

package teste;

public class Client {
    public static void main(String[] args) throws Exception {
        Properties properties = new Properties();

properties.put("org.omg.PortableInterceptor.ORBInitializerClass.org.jboss.tm
.TxClientInterceptorInitializer","org.jboss.tm.TxClientInterceptorInitialize
r");

properties.put("ORBInitRef.NameService","corbaloc::localhost:3528/JBoss/Nami
ng/root");

        org.omg.CORBA.ORB orb = org.jacorb.orb.ORB.init(args, properties);
        org.omg.CORBA.Object objPOA =
orb.resolve_initial_references("RootPOA");
        org.omg.PortableServer.POA poa =
            org.omg.PortableServer.POAHelper.narrow(objPOA);
        poa.the_POAManager().activate();

        org.omg.CORBA.Object objTxCurrent =
orb.resolve_initial_references("TransactionCurrent");
        Current txCurrent = CurrentHelper.narrow(objTxCurrent);
        System.out.println("TransactionCurrent: " + txCurrent);
        CreateEx createEx = new CreateEx();

        // txCurrent.begin();

        org.omg.CORBA.Object objNc =
orb.resolve_initial_references("NameService");
        NamingContextExt nc = NamingContextExtHelper.narrow(objNc);
        org.omg.CORBA.Object obj =
orb.string_to_object(nc.resolve_str("ejb/ep2/SConta").toString());
        SContaHome home = SContaHomeHelper.narrow(obj);
        SConta session = home.create();
        // session.criaConta(1, 100, 0);
==> session.debitar(1, 100); <==

        // txCurrent.commit(true);
    }
}


Não fazemos a menor idéia do motivo disto. Se alguém souber de algo sobre o
um possível motivo para isso acontecer, por favor nos ajude.


quando executamos com a linha acima descomentada (session.criaConta()) temos
a seguinte exception:
