RE: How to start a Realm from a servlet or a filter
Realm is not accessible to servlet or filter. In anther word, you can't do
what you are trying to do.
Let's suppose for a second that your code could work, then I can write a
servlet to replace your realm or any realm tomcat is using. And image what
could happen if the tomcat manager interface is using that realm?
Thanks
Daniel

Subject: How to start a Realm from a servlet or a filter
Hi,
because of technical reasons I want to start a Realm class during run-time,
thus I cannot just configure Realm via Realm When I try to start
MemoryRealm I get a null pointer exception, because the container of Realm
is not set. The application does work (because I catch the exception) but I
would like to start Realm correctly.
What is wrong in my example?
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup(java:comp/env);
Object realm_instance = envCtx.lookup(realm/RealmFactory);
log.info(Realm class: + realm_instance.getClass().getName());
Realm rlm = (Realm)realm_instance;
if (rlm instanceof Lifecycle)
{
try
{
// rlm.setContainer(...); Is that the problem
((Lifecycle) rlm).start();
}
catch (Exception e)
{
log.error(LifecycleException (start): + e.getMessage(), e);
}
Here is my web-application configuration file:
Context path=/cb docBase=cb debug=0 reloadable=true
Resources className=org.apache.naming.resources.FileDirContext
allowLinking=false /
Resource name=realm/RealmFactory auth=Container
type=org.apache.catalina.realm.MemoryRealm/

Hi, Realm is not accessible to servlet or filter. In anther word, you can't do what you are trying to do. How authoritative and conclusive. And wrong. Realms and all other tomcat internals are accessible to any code you write. You just have to mark your webapp as privileged and in some instances (depending on your code) place portions of your code in the common rather than your webapp's classloader.

RE: How to start a Realm from a servlet or a filter
Hi, And how can I access or start a Realm? What is up with this list? Do people don't know how to read JavaDocs, or do they simply not care? Sigh... Server server = ServerFactory.getServer(); Service service = server.findService(Catalina); Container serviceContainer = service.getContainer(); Realm serviceRealm = serviceContainer.getRealm(); // May be null You would/can continue to drill down from the service using findChildren to locate Engine/Host/Context elements and their associated Realms, if any. As to how to start one: look at the tomcat startup code, that's why it's open-source.

RE: How to start a Realm from a servlet or a filter
Yoav,
I have written this code, but srv is always an empty array.
I use tomcat-5.0.19
Server server = ServerFactory.getServer();
Service service = server.findService(Catalina);
Service[] srv = server.findServices();
for (int i = 0; i srv.length; i++)
{
Service s = srv[i];
log.debug(SERVICE: + s.getName());
}
Zsolt
