javax.naming.NameNotFoundException: Name java: is not bound in this Context

[Veniamin Fichin <3c...@mail.ru>]

Hello list!

    I wrote a message about this problem yesterday, but did not receive 
any reply. I can accept the fact that nobody faced this problem, but may 
be somebody have done similar task before, and can share your experience 
with me and others?
    Lets describe the problem. I want to restrict access to some area at 
my site using FORM authentication. I've added Realm definition in 
config.xml:

<Realm className="org.apache.catalina.realm.DataSourceRealm"
        dataSourceName="java:/comp/env/jdbc/esljsp"
        debug="5"
        userTable="T_USERS"
        userNameCol="NAME"
        userCredCol="PASSWORD"
        userRolesTable="T_USERROLES"
        roleNameCol="ROLENAME" />

...and security constraints in web.xml:

<security-constraint>
  <web-resource-collection>
   <web-resource-name>Administrator's interface</web-resource-name>
   <url-pattern>/adm/*</url-pattern>
   <http-method>GET</http-method>
   <http-method>POST</http-method>
  </web-resource-collection>
  <auth-constraint>
   <role-name>Administrator</role-name>
  </auth-constraint>
</security-constraint>
<login-config>
  <auth-method>FORM</auth-method>
  <realm-name>Administrator's interface</realm-name>
  <form-login-config>
   <form-login-page>/login.jsp</form-login-page>
   <form-error-page>/login_error.jsp</form-error-page>
  </form-login-config>
</login-config>
<security-role>
  <role-name>Administrator</role-name>
</security-role>

    During Tomcat startup process, I see following in logs:

2003-01-16 12:56:19 DataSourceRealm[/esljsp]: Exception performing 
authentication

    And these lines appears in logs _before_ configuring DataSource, 
which completes fine. I've been told that this may be due to different 
classloaders (Catalina level and WebApp level), but I'm not sure, 
because it's strange -- to be unable to find java: name...
    I can (or at least try to) use JDBCRealm to make it work, but as 
soon as I have DataSource properly configured, I want to use it. I 
tested it in a servlet, and it works.
