PGSQL exception

[Rishat Valeye]

I installed PostgreSQL, jBoss, set up JAAS authetification.
Here is the datasource:

    <datasource jndi-name="java:jboss/datasources/myds" pool-name="myds" enabled="true"         use-java-context="true">
       <connection-url>jdbc:postgresql://localhost:5432/my_db</connection-url>
       <driver>com.postgresql</driver>
       <security>
          <user-name>bd_user</user-name>
          <password>pswd</password>
       </security>
    </datasource>
    <drivers>
       <driver name="com.postgresql" module="com.postgresql">
          <xa-datasource-class>org.postgresql.xa.PGXADataSource</xa-datasource-class>
       </driver>
    </drivers>

And here is the login module:

   <login-module code="Database" flag="required">
       <module-option name="dsJndiName" value="java:jboss/datasources/myds"/>
       <module-option name="principalsQuery" value="SELECT password FROM tuser WHERE login=?"/>
       <module-option name="rolesQuery" value="SELECT role_id, 'Roles' FROM user_role WHERE tuser=?"/>
    </login-module>

But when I press Login button I got the following exception:

   17:37:47,553 ERROR [stderr] (http--127.0.0.1-8080-1) org.postgresql.util.PSQLException:      ╬╪╚┴╩└: эхЄ фюёЄєяр ъ юЄэю°хэш■ tuser

The strange symbols is not a mistake, i really see them in console I've got the same exception when I try to executeQuery from java code.
I've got no idea what does it mean. Can anyone help me?
