I added a javamail session to the global resource
			

			configuration as follow:
			

			

			

			

			mail.smtp.host
			

			smtp.myhost.net
			

			

			

			mail.debug
			

			true
			

			

			

		

			

			I added a resource reference to the web.xml file as follow:
			

			

			

			mail/Session
			

			javax.mail.Session
			

			Container
			

			

			

		

			

			using JNDI lookup I am able to retrieve the Session ref:
			

			Context nctx = new InitialContext();
			

			session  = (Session) nctx.lookup("java:comp/env/mail/Session");
			

			

			However, when I log the session properties I'm getting
			

			session properties: {mail.transport.protocol=smtp, scope=Shareable, auth=Container, mail.smtp.host=localhost}
			

			

			As you can see the mail.smtp.host property is set to the local host not to the smtp.host that i specified in the server.xml configuration file.
			

			

			Is this a tomcat problem configuration problem?
			

		

when I explicitliy setup the properties in my servlet as follow:
session.getProperties().put"mail.smtp.host","smtp.myhost.net");
session.getProperties().put("mail.from", "from");

The servlet works.
