how to access MBeanServer

[dirk.haase]

Hi,

I need to flush the security domain authentication cache. I found that little code snippet in the JBoss dokumentation that starts with
MBeanServer server = ...;
Unfortunately, I have no clue how to get the MBeanServer, i.e. I dont know how to completet this line. Could somebody please help me on this?

thanks,
Jex

MBeanServer server = (MBeanServer) MBeanServerFactory.findMBeanServer(null).iterator().next();

There is only one MBeanServer in JBoss.

thanks, that worked. At least it didnt cause any errors. But I still cant seem to flush the cache. Maybe you also have an idea what wrong with this code :

MBeanServer server = (MBeanServer) MBeanServerFactory.findMBeanServer(null).iterator().next();
ObjectName jaasMgr = new ObjectName("Security:name=JaasSecurityManager");
Object[] params = {"java:/jaas/usermgmt-secure"};
String[] signature = {"java.lang.String"};
server.invoke(jaasMgr, "flushAuthenticationCache", params, signature);
log.info("Cache flushed.");

in jboss.xml I have following line
<security-domain>java:/jaas/usermgmt-secure</security-domain>
to set the security domain. Is this the String I need to use as parameter in the invoke statement?

thanks,
Jex

This is probably a question for the security forum.
Your JMX code looks fine, whether you are passing the
correct value is another question.

NOTE: jboss.xml isn't used here. You are going outside
the container when you access JMX directly.
