RE: Does any one has a solution for the "domain was null" message???

Earl, I was only replying to your message where you indicate:

 

"I suggest you try the ApplicationInitialContextFactory instead of the
ApplicationClientInitialContextFactory in your situation."

 

I was only saying that using ApplicationInitialcontextFactory will not work in my case.  There is no aspect that you do not  understand.  It's quite simple.  Just try to create a new InitialContext(p) where p contains ApplicationClientInitialContextFactory.  During the creation of InitialContext you will get a NullPointerException with the message of "domain was null". 

 

Jason Smith did a good job of documenting of how to connect two Orion servers together using RMI.XML file, however, this does not seem to be J2EE compliant.  I still want to use the solution where InitialContext can be used to connect to a different server.

 

For now, we are deploying our application in the same server using the parent="application-name" tag.

If you use the ApplicationClientContextFactory it will read META-INF/application-client.xml which is where you can specify the <ejb-ref> and <env-ref> elements... There still must be some other aspect of your situation that I don't understand.


In answer to my own question, I finally discovered how the rmi authentication works in conjunction with an EJBUserManager. It was not clear from the error messages. After reading the article at orionsupport on the DataSourceUserManager, studying the orion examples and docs and an intuitive guess, I added the permissions to a group in the application's principals.xml, e.g.:

<group name="RMIUsers">
        <description>rmi users</description>
        <permission name="rmi:login" />
        <permission name="com.evermind.server.rmi.RMIPermission" />
</group>

(Can someone explain the permissions in relation to the groups or point me to a reference? I'm still not sure which of the two or whether both are required and why. It works for now...)

This group name is added in the orion-application.xml which also directs the application to use the custom EJB user manager:

<user-manager class="com.evermind.ejb.EJBUserManager">
        <property name="defaultGroups" value="ValidatedUsers" />
        <property name="home" value="ejb/CustomEJBUserBean" />
</user-manager>
...
<namespace-access>
        <read-access>
                <namespace-resource root="">
                        <security-role-mapping>
                                <group name="RMIUsers" />
                        </security-role-mapping>
                </namespace-resource>
        </read-access>
        ...
</namespace-access>

Now my application client is successful in connecting to the rmi server, authenticating a user account via the EJBUserManager and accessing my application.

cannot be put into application.xml.

There may be a clue to this question in the following error message that is
generated when trying the
com.evermind.server.ApplicationInitialContextFactory from an application
client:

"javax.naming.NamingException:
com.evermind.server.ApplicationInitialContextFactory should only be used
inside Orion server environments. For client
com.evermind.server.ApplicationClientInitialContextFactory or
com.evermind.server.rmi.RMIInitialContextFactory should be used"

I suggest you try the ApplicationInitialContextFactory instead of the
ApplicationClientInitialContextFactory in your situation.


Somewhat related, I have been trying to get an application client working.
I have succeeded in connecting to the orion rmi server, looking up an ejb,
and retrieving data. I would like to authenticate against the
EJBUserManager that is configured for our web applications. However, it
appears that the rmi authentication defaults to XMLUserManager - i.e., I
can only authenticate for users defined in the principals.xml file. This
could be related to the orion Bugzilla #374. Can anyone provide some
insight into the RMI authentication? Thanks.

Regards,

Earl
