datasource not bound

[r_tacchi]

I'm trying use DatabaseServerLoginModule , but when try to access DatabaseServerLoginModule I'm getting Exception that Datasource not bound.
My code

login-config.xml :


<application-policy name="tpmrealm">

<login-module code="org.jboss.security.auth.spi.DatabaseServerLoginModule"
flag="required">
<module-option name="dsJndiName">java:/OracleDS</module-option>
<module-option name="principalsQuery">
select password from PERSEO.TPM_UTENTI where username=? and flg_abilita='S'
</module-option>
<module-option name="rolesQuery">
select id_ruolo ,'Roles' from TPM_UTENTE_RUOLI where username=?
</module-option>
</login-module>

</application-policy>



Client program :

String j_username = null;
String j_password = null;
ActionErrors errors = null;
try {
// validazione
if (isDebug())
logger.debug("inizio");
j_username = ((LoginForm) form).getJ_username();
j_password = ((LoginForm) form).getJ_password();
if (isDebug())
logger.debug("Tentativo autenticazione per l'operatore "
+ j_username + " ...");
SecurityAssociationHandler handler = new SecurityAssociationHandler();
SimplePrincipal user = new SimplePrincipal(j_username);
handler.setSecurityInfo(user, new String(j_password));
LoginContext loginContext = new LoginContext("tpmrealm",
(CallbackHandler) handler);


loginContext.login();
Subject subject = loginContext.getSubject();
// creazione UserBean*/
UserBean userBean = new UserBean();
// verifico se il ruolo consente l'accesso
hasRole(subject, userBean);

userBean.setUserID(j_username);
userBean.setPwd(j_password);

SecurityService securityService = (SecurityService)ServiceUtil.createServiceObject(SecurityService.class
.getName());

oracle-ds.xml :

<?xml version="1.0" encoding="UTF-8"?>

<local-tx-datasource>
<jndi-name>OracleDS</jndi-name>
<connection-url>jdbc:oracle:thin:@138.132.95.83:1522:AT1</connection-url>
<driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
<user-name>perseo</user-name>
perseo

<type-mapping>Oracle9i</type-mapping>

</local-tx-datasource>



Exception when running the client program :

javax.naming.NameNotFoundException: OracleDS not bound


I use Jboss 4.0.2 .
