Preventing reconnect attempt of remote ejb client

Hi,

I have a remote ejb client and a custom login module. I am testing my login module, i enter an invalid password in remote client. My login module runs correctly and send an exception. However, remote client attempts to recall login module again to login user. But i do not want this. Because when there is an exception in my custom login module, i update some values in my database. Therefore the same code in login module runs twice and my db has inconsistent values. So how can i prevent this reconnect attemp of remote ejb client? I use JBOSS 7.1.2 Final SNAPSHOT version in server and jboss 7.1.1 client maven dependencies. Thanks.

My Client code is like below:

Properties pr = new Properties();
pr.put("endpoint.name", "client-endpoint");
pr.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED", "false");
pr.put("remote.connections", "default");
pr.put("remote.connection.default.port", "4447");
pr.put("remote.connection.default.host", "localhost");
pr.put("remote.connection.default.connect.options.org.xnio.Options.SASL_DISALLOWED_MECHANISMS", "JBOSS-LOCAL-USER");
pr.put("remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS", "false");
pr.put("remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT", "false");
pr.put("remote.connection.default.username", "user1");
pr.put("remote.connection.default.password", "Test12345");

EJBClientConfiguration cc = new PropertiesBasedEJBClientConfiguration(pr);
ContextSelector < EJBClientContext > selector = new ConfigBasedEJBClientContextSelector(cc);
EJBClientContext.setSelector(selector);

Properties props = new Properties();
props.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
props.put("jboss.naming.client.ejb.context", true);

try

{ Context c = new InitialContext(props); kullaniciEJB = (KullaniciEJBRemote) c.lookup("ejb:merveys-kayit-tckkys/merveys-kayit-ejb-tckkys//KullaniciEJB!tr.gov.tubitak.bilgem.uekae.deys.tckk.merveys.common.controller.ejb.kullanici.KullaniciEJBRemote"); }

catch (NamingException e) {
e.printStackTrace();
}
int count = kullaniciEJB.countKartIslemList(1L, null, null);
