Re: Jaas and Jndi problem

[Peter Rossbach]

Hello,

your Login Module in the server env  and you must access the 
GlobalNamingContext
from server direct.

import java.sql.Connection;
import java.sql.SQLException;
import javax.naming.Context;
import javax.sql.DataSource;
import org.apache.naming.ContextBindings;
import org.apache.catalina.ServerFactory;
import org.apache.catalina.core.StandardServer;
public class xxx {
  ....
  public Connection open(String dataSouceName) {
       try {
           Context context = null;
           StandardServer server =
                   (StandardServer) ServerFactory.getServer();
           context = server.getGlobalNamingContext();
           DataSource dataSource = 
(DataSource)context.lookup(dataSourceName);
       return dataSource.getConnection();
       } catch (Exception e) {
           // ???
       } 
       return null;
   }
}

Only at your web application you have a comp/env JNDI Tree ( Look at 
resource-link server.xml configuration)

Hello,

I'm stuck with the problem trying to get a way out for several hours:
I have a database resource declared in server.xml in 
GlobalNamingResources part
Also I have a JAAS login module which is intended to use this JNDI 
database resource.
And I can't get access to this resource my JAAS login module. The 
error is

...

     </ResourceParams>
...
</GlobalNamingResources>

code from login module:
...
Context ctx = new InitialContext();
if (null==ctx) throw new Exception("No context");
Context envCtx = (Context)ctx.lookup("java:comp/env");
if (null==envCtx) throw new Exception("No context");
DataSource ds = (DataSource)envCtx.lookup("jdbc/MerxDB");
...
Is there any way out? Any help is greatly appreciated.
