Conectar Java Oracle 10g

[keybeth]

Yo creo presento es el siguiente problema, instale la version 10g Express Edtion(XE), y perfecto de hecho puedo acceder a la interfaz grafica y realizar mis labores con la base de datos, tome las librerias que trae la instalacion (ojdbc14.jar,ojdbc14_g.jar y orai1n.jar) y las incorpore a mi classpath. Tambien revise el tnsnames.ora y el listener ora y me sigue presentando la siguiente excepcion:

java.sql.SQLException: ORA-00604: error occurred at recursive SQL level 1
ORA-12705: Cannot access NLS data files or invalid environment specified

Mi metodo para lo conexion es el siguiente:

Mi clase tiene la importacion de las librerias de jdbc de oracle (ojdbc14.jar, orai18n.jar)


private final OracleDriver driver= new OracleDriver();
private final String bd = "XE";
private final String url = "jdbc:oracle:thin:@127.0.0.1:1521:"+bd;
private final String usr = "miUsuario";
private final String clave = "miClave";

public final Connection ConexionBD() {
Connection conn = null;
try {
DriverManager.registerDriver(driver);
} catch (Exception e) {
System.out.println(e);
}

try {
conn = DriverManager.getConnection(url, usr, clave);
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
conn.setAutoCommit(false);
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

return conn;
}


el tnsnames.ora: quedo asi

XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = colossus)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
)
)

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)

ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)

el listener.ora asi:

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = C:\Oracle\app\oracle\product\10.2.0\server)
(PROGRAM = extproc)
)
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\Oracle\app\oracle\product\10.2.0\server)
(PROGRAM = extproc)
)
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
(ADDRESS = (PROTOCOL = TCP)(HOST = colossus)(PORT = 1521))
)
)

DEFAULT_SERVICE_LISTENER = (XE)


De ante mano gracias....
