Hi,

I am migrating my non-osgi project to virgo and I am having trouble using jaas authentication in virgo.
I have 2 questions regarding virgo and jaas.

a. I have my own jaas LoginModule implementation and I want virgo to authenticate the administration user that connects to Web Servers using that implementation.
I have changed the org.eclipse.virgo.kernel.authentication.config file to use my class:

virgo-kernel {
acme.security.MyLoginModule REQUIRED;
};

and exposed my class to the service registry, but how do I tell virgo to reference that service and use it for authentication ?

b. I am using the ActiveMQ bundle as my jms implementation and I want it to use my jaas login module as well but I am getting an exception saying the class cannot be found in KernelBundleClassLoader: [bundle=org.apache.activemq.activemq-core_5.4.1].
I have tried asking about this exception in the activemq forum and I was told that JAAS does not work in OSGi, and I need to use a specific integration layer in order to make that work. Does virgo have somthing like this ?

Here is the full exception stacktrace:
10:34:45.262 [ActiveMQ Transport: tcp:///127.0.0.1:51561] WARN o.a.a.broker.TransportConnection - Failed to add Connection

Virgo does not register its login module as a service. Take a look at the hits in the search.

Have you already compared the code of your login module with Virgo's?

I don't need the LoginModule for virgo to be a service but I do need it to reference another service for database queries.
Is it possible to change the LoginModule used by virgo ?
If it is possible how is it done and can the new LoginModule use services from the Registry ?

About my second question, are you aware of a way that I can use a custom login module for activemq in Virgo ?

It should be. Just start with Virgo's login module and make sure you can rename it and use it in place of Virgo's. Then change it incrementally and re-test often.

The login module configuration is passed to the Java startup using "-Djava.security.auth.login.config", so the JRE is going to load the login module class and so it won't have access to a bundle context or the service registry.

Note that the JAR containing the login module needs to appear on the JREs classpath. We do this for the Virgo login module by putting the JAR in the lib directory.

I'm sorry, but I'm not aware of how to do that.

My problem is that the ActiveMQ bundle cannot find the class acme.security.MyLoginModule( unable to find LoginModule class: acme.security.MyLoginModule in KernelBundleClassLoader: [bundle=org.apache.activemq.activemq-core_5.4.1] )

because it doesn't have the proper import, is it possible to use the org.osgi.framework.bootdelegation property to solve that problem? how is it defined in virgo ?

Look in $VIRGO_HOME/lib/java6-server.profile

You also have to make sure that anything you specify in org.osgi.framework.bootdelegation property is available on the classpath of virgo.

Virgo scans lib directory for all the jars there and adds them to the -cp during start up. If you need to add other locations or directories you can do it with creating a setenv.sh/bat file in bin folder and set-up $CLASSPATH variable there.

i.e.

CLASSPATH=$CLASSPATH:/some/directory:/some/dir/jar.file.jar

Regards,
Dmitry
