Tomcat 6.0.24 java emailing configuration problem
I am trying to configure javax.mail for our application running under
Servlet Engine: 2.5
JSP Engine: 2.1
Application Server: Apache Tomcat/6.0.24
But emailing never works. The smtp server is up and running on the server.
We can send email via the command line from localhost.
Please help.
Our system is running on Red Hat Enterprise Linux Server release 6.2
(Santiago) Linux xxx.xxx.xxx 2.6.32-220.4.2.el6.x86_64 #1 SMP Mon Feb 6
16:39:28 EST 2012 x86_64 x86_64 x86_64 GNU/Linux

The mail.jar comes from JavaMail 1.4.4
############################################################################
#######################################
Here is the source java code that sends out email:
...
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
Session mSession = (Session) envCtx.lookup("mail/Session");
Based on my logging information, the code breaks right at the last line
--->Session mSession = (Session) envCtx.lookup("mail/Session");
############################################################################
#######################################
When I run the application the server gives the following error:
javax.mail.Session cannot be cast to javax.mail.Session.
No email is sent.

If I remove mail.jar, then the application is broken and root cause is:

I am guessing that classloading must have included some javax.mail somewhere
which conflicts with mail.jar under tomcat6/lib.
Please give me some suggestions.
Thanks,

Hi,
I finally figured out what went wrong. There is a third party .jar file under application/WEB-INF/lib. That jar file also contains javax.mail class.
Thanks for your help.

This is usually indicative of a classpath error - meaning that you have the class specified in two places on the classpath and Tomcat is selecting one of each, rather than the same one.
The fact that you have symlinked jars all over the place is probably not helping.
Download & install a fresh version from tomcat.apache.org and start over.
Make sure only one version of mail.jar exists in tomcat/lib and not anywhere else.
