Jboss and Jaas: where do I go wrong?

[erika santo]

Hi everybody

I'm new in this forum and I'm a newby. I'm stuck from a couple of days and really need some help.

I am using Jboss 5.1, java 1.6 and I'm developing a web application that needs login.
I'd like to uso JAAS functionality so this is what I have done:

- I wrote my own LoginModule and my own Principal
- Modified the jboss-web.xml as follows:

<security-domain>java:/jaas/LoginModuleRDS</security-domain>

- Modified the login-conf.xml in jbossdirectory/server/default/conf as follows:

<application-policy name="LoginModuleRDS">
<authentication>
<login-module code="security.HibernateLoginModule"
flag="required">
<module-option name="restore-login-identity">true</module-option>

</login-module>
</authentication>
</application-policy>

and deployed.

When I run the application I correctly see the log-in page.
My LoginModule is correctly called and correctly executed but then I get the following error:

The first 5 lines are logs that i'll delete as soon as i get this working.
