How to verify that embedded OC4J is loading Custom LoginModule?

Question

I've written a custom login module to authenticate against a custom datastore. I've added a system property
java.security.auth.login.config=C:\javadev\...\jaas.configas recommended by Yvonne here: Re: Custom LoginModule used by BC4J
I still get the following when I load a UIX page out of this module:
msg=JBO-33021: Failed authenticate user nullThere are many debug System.out(...) statements in the code (including in the initialize() function) but none are showing up in the OC4J console. Does anyone know how to verify that the LoginModule is indeed getting loaded? Is it normal for these System.out() statements not to show in the OC4J console?
I get the impression that the LoginModule is not being loaded but I'm not sure if those traces are enough...
Thanks,

Thanks much for the prompt reply and debugging tips Steve and Avi!
I used both switches (-DApplicationServerDebug and -verbose:class) and still no sign of the class being loaded; none of the traces (I did trace in the construct, though I failed to mention in my original post) nor do any of the app server or jvm debug messages show any sign of the LoginModule being loaded. So now I'm fairly certain I'm going about the wrong way to get this module loaded. Should I also be posting this to the JDeveloper forum?
My application module configuration is as follows:
jbo.security.config=<blank> (is this right?)
jbo.security.context=oracle.security.jazn
jbo.security.enforce=Must
jbo.security.loginmodule=customModuleThe command line to the JVM contains:
-Djava.security.auth.login.config=C:\javadev\jdev9052\j2ee\home\config\jaas.config[yes Avi, I was unfortunately imposed an M$ env. by the powers that be : ( ]
And, well I've been trying a lot of different things w/ the jaas.config file:
customModule{
myPack.controller.MyLoginModule required;
myApp{
myPack.controller.MyLoginModule required;
myPack.LookupModuleLocal{
myPack.controller.MyLoginModule required;
myPack.LookupModule{
myPack.controller.MyLoginModule required;
Ws-MyProg-webapp{
myPack.controller.MyLoginModule required;
default{
myPack.controller.MyLoginModule required;
current-workspace-app{
myPack.controller.MyLoginModule required;
};Any idea where I'm going wrong? Do I need to do anything else to get this module loaded? At first I thought I needed to modify the jazn-data.xml file but I saw a note in another thread Custom LoginModule used by BC4J which says that it's not necessary to modify it when using a custom LoginModule. Is this right, or should I be modifying that file?
Thanks,
