Problem w/JavaMail Session: No AUTH command given

[Gary Horton <Ga...@Sun.COM>]

I've configured my web.xml, context.xml, code snippets and library 
deployment as directed in 
http://localhost:8081/docs/jndi-resources-howto.html, the JavaMail 
section, and can locate my JNDI resource just fine, but attempts to send 
the mail result in an SMTP 530 error,"No AUTH command given". From 
google searches and my own experimentation, I've concluded I need to use 
an approach where I create my own Session and supply username, password 
in the Transport.connect() call. While this works (i.e authentication is 
given OK and the mail gets sent OK), it does not use the 
container-supplied session, so it precludes the need for the JNDI 
configuration. What is the technique that enables use of a JNDI javamail 
resource from Tomcat 6 and have the authentication taken care of?

Thanks-
