------------------------------------------------------------------------------------
11:10:20,390 ERROR [PersistenceManager] Starting failed
java.lang.SecurityException: Invalid authentication attempt, principal=null
at org.jboss.resource.connectionmanager.BaseConnectionManager2.getSubject(BaseConnectionManager2.java:660)
at org.jboss.resource.connectionmanager.BaseConnectionManager2.allocateConnection(BaseConnectionManager2.java:487)


------------------------------------------------------------------------------------




and while accessing the home interface create method from my client i get the exception as below
------------------------------------------------------------------------------------
13:11:42,734 ERROR [LogInterceptor] RuntimeException:
java.lang.SecurityException: Invalid authentication attempt, principal=null

------------------------------------------------------------------------------------





In my Bean class i wrote the following code for connecting to the database
------------------------------------------------------------------------------------
public Connection makeConnection() throws SQLException {
try {
Context jndictx = new InitialContext();
DataSource ds = (DataSource) jndictx.lookup("java:comp/env/MySqlDS");
con = ds.getConnection();
System.out.println("Connection got");
return con;
} catch (NamingException ne) {
throw new EJBException(ne);
}
}
------------------------------------------------------------------------------------


I modified the mysql-ds.xml as
------------------------------------------------------------------------------------

<local-tx-datasource>
<jndi-name>MySqlDS</jndi-name>
<connection-url>jdbc:mysql://localhost/bmp</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<user-name>jinu</user-name>

</local-tx-datasource>

------------------------------------------------------------------------------------


accordingly i modified login-config.xml as

------------------------------------------------------------------------------------
<application-policy name="MySqlDbRealm">

<login-module code="org.jboss.resource.security.ConfiguredIdentityLoginModule" flag="required">
<module-option name="unauthenticatedIdentity">Anonymous</module-option>
<module-option name = "principal">jinu</module-option>
<module-option name = "userName">jinu</module-option>
<module-option name ="password"></module-option>
<module-option name ="managedConnectionFactoryName">
jboss.jca:service=LocalTxCM,name=MySqlDS
</module-option>
</login-module>

</application-policy>
------------------------------------------------------------------------------------

and standardjaws.xml as
------------------------------------------------------------------------------------

java:/MySqlDS
<type-mapping>mySql</type-mapping>
false
..................
------------------------------------------------------------------------------------

and standardjbosscmp-jdbc.xml as
------------------------------------------------------------------------------------
<jbosscmp-jdbc>


java:/MySqlDS
<datasource-mapping>mySql</datasource-mapping>
........................

------------------------------------------------------------------------------------
