Re: Tomcat 5.0 and JavaMail

 Don't get in the habit of putting jars in java_home/jre/lib/ext.  
Those jars get loaded before everything and ugly version conflicts among 
other problems show up.

I have a different take on your problem.  Are you using Tomcat 5.0.25?  
If so, you may want to consider upgrading or just stealing 
common/lib/naming-factory.jar from a 5.0.24 version of Tomcat.  
org.apache.naming.factory.MailSessionFactory is missing from tomcat 
5.0.25.  See this message from the archives:

I've found that you also need activation.jar for JavaMail, do you have
this in common/lib too?

I had JavaMail working in Tomcat 4, but in Tomcat 5, I am having
trouble. I know it's something simple, perhaps you can see the problem.
Mail.jar is in Tomcat 5.0\common\lib.
I am getting this error:
"javax.naming.NamingException: Cannot create resource instance:"
Using this context in Tomcat 5.0\conf\Catalina\localhost\e_Denton.xml
"<Context displayName="Portal Application"
        debug="5"
        docBase="e-Denton"
        path="/e-Denton"
        reloadable="true"
        useNaming="true">
   <Loader checkInterval="1" />
<Resource name="mail/Session" auth="Container"
type="javax.mail.Session" />  <ResourceParams name="mail/Session">
 <parameter>
  <name>mail.smtp.host</name>
  <value>mars.webappcabaret.net</value>
 </parameter>
</ResourceParams>
..."
And this web.xml:
"<!-- JavaMail Resource -->
<resource-ref>
 <description>
 Resource reference to a factory for javax.mail.Session
 preconfigured to connect to the appropriate SMTP server.
 </description>
 <res-ref-name>mail/Session</res-ref-name>
 <res-type>javax.mail.Session</res-type>
 <res-auth>Container</res-auth>
</resource-ref>"
Accessed like this:
 "try
  {
  Context initContext = new InitialContext();
  Context envContext  = (Context) initContext.lookup("java:comp/env");
  Session session = (Session) envContext.lookup("mail/Session");
  }
 catch (javax.naming.NamingException ne)"
