RE: Possible values in web.xml - Reference??

[johannes . fiala]

Hi Phil,

if you make changes to web.xml env-entries and stop/start the application 
using the manager app, do your changes show up? My changes didn't show up, 
only after a complete restart of the Tomcat Container.

thx
Johannes

Try something like this:

import javax.naming.Context;
import javax.naming.InitialContext;
...
Context initialContext = null;
try {
                 initialContext = new InitialContext();
}
catch (Exception e) {
      out.print("<li>Cannot get initial context for JNDI: ");
      out.println(e + "</li>");
                 return;
}
Integer envEntry = null;
try {
                 envEntry = (Integer) 
initialContext.lookup("java:comp/env/name3");
} 
catch (Exception e) {
                 out.println("<li>Cannot get env-entry on JNDI " + e + 
"</li>");
      return;
}
...

See  http://www.objectweb.org/jonas/current/doc/PG_War.html for a more
complete explanation - it really helped me.
