The UserDatabaseRealm can do this, look at it as an example.

So is there a way to access my own realm implementation from Servlet ?

The DataSourceRealm uses a JNDI named JDBC DataSource, it is not a
JNDI named resource itself.

Hi,

I implemented my own class for user authentication based on RealmBase
class, basicaly it's DataSourceRealm class just changed to my needs
(added some methods like getUserRealName() etc.)
So the class is

public class MyDataSourceRealm
   extends RealmBase {.

I put jar with my class  in tc_home/server/lib, defined it in
server.xml. And everything is working OK.

Only problem that I have is that I can't access that class from
servlet

and use some of my added methods, like this:

try{
Context ctx = new InitialContext();
MyDataSourceRealm um =
(MyDataSourceRealm)ctx.lookup("java:comp/myDataSourceRealm");
String sFullName = um.getFullName(req.getRemoteUser());
}
catch(NamingException e){
System.out.println(e.toString()); }

I get :

javax.naming.NameNotFoundException: Name myDataSourceRealm is not
bound

in this
Context

So, how I can gain access to myDataSourceRealm ?

Thanx
