how to get jboss jndi in tomcat5.x

[David Chen <Da...@digital-dispatch.com>]

Hi, there:
 
We are going to switch our web server from jetty to TomCat. We will run
tomcat and jboss separately. I used tomcat 3.x long long times ago, and to
use tomcat 3.x to lookup jboss jndi, a. copied jndi.properties to
common\classes directory; b. run it with -nonaming option.
However, we are going to use TomCat 5.x, I tried the same above steps, I got
exception about UserDatabase like:
2005-12-01 15:14:15 UserDatabaseRealm[Catalina]: Exception looking up
UserDatabase under key UserDatabase
java.lang.NullPointerException........
Checked internet there are some options to get TomCat 5.0 talk to JBoss
without changing any source code:
a. someone suggest removing UserDatabaseRealm from server.xml before using
-nonaming option;
b. modified catalina.bat
JAVA_OPTS=-Djava.naming.factory.initial=org.jnp.interfaces.NamingContextFact
ory -........
I tried option b above, and it works fine for me. However, just wonder if
any other options to set up jndi resource for my web application to talk to
jboss without changing my source code? Any sample example about how to
create such kind of jndi resource in <Context>?
 
Thanks a lot in advance, highly appreciated any suggestion.
