Hi,

We have a Swing based GUI application that connects to a JBoss EJB server and we need to know if a user is already logged into the server. I'm looking at the getAuthenticationCachePrincipals method in the JMX bean JaasSecurityManager to return me a list of authenticated users. I've got the code working O.K. but the method always returns me an empty list.

MBeanServerConnection server = MBeanServerConnection)ctx.lookup("jmx/rmi/RMIAdaptor");

ObjectName jaasMgr = new ObjectName("jboss.security:service=JaasSecurityManager");

Object[] params = {p_strSecurityDomainName};

String[] signature = {"java.lang.String"};

List users = (List) server.invoke(jaasMgr, "getAuthenticationCachePrincipals", params, signature);

I have double checked that the DefaultCacheTimeout is set to a non zero value. We are using a custom login module which extends the UsernamePasswordLoginModule....we are calling the super methods everywhere as well. Here is the entry in the login-config.xml file for our domain.

<application-policy name="ucmslc">
 <authentication>
 <login-module code="ucs.common.security.ucms.JBossLoginModule" flag="optional">
 <module-option name="applicationName">UCMS-LC</module-option>
 <module-option name="principalUserRole">lccmsUser</module-option>
 <module-option name="addSecurityGroupsAsRoles">false</module-option>
 </login-module>
 </authentication>
</application-policy>

Anybody ever get this method call working successfully?

Thanks,

Cliff
