java mail - smtp config problem

[Torque]

I'm trying to send mail from my JSP app. I've followed the instructions for configuring my server.xml to specify the address of my ISP's smtp server, as in:
<Resource name="mail/Session" auth="Container"
type="javax.mail.Session"/>
<ResourceParams name="mail/Session">
<parameter>
<name>mail.smtp.host</name>
<value>smtp.myservername.com</value>
</parameter>
</ResourceParams>
The odd thing is, I get an error message:
javax.servlet.ServletException: Sending failed;
nested exception is:
javax.mail.MessagingException: Could not connect to SMTP host: localhost, port: 25;
So it looks as though tomcat is looking for the SMTP host on localhost, rather than on the SMTP server I specified.
With a Google search I found a few people asking the same question but no answers, so I guess it's something silly they figured out eventually. Any ideas?

It sounds like Tomcat is using localhost as a default because it never picks up that parameter setting.

It's 18 months later and I had a PM asking how I'd solved the problem. My memory is a bit scratchy, but I think it was that I had a case difference between the server.xml and web.xml, where the web.xml has an entry like this:
<resource-ref>
<res-ref-name>mail/Session</res-ref-name>
<res-type>javax.mail.Session</res-type>
<res-auth>Container</res-auth>
</resource-ref>

If I remember rightly, I had Session (capital S) in one place and session (small s) in the other. Just one of those stupid gotchas that eats programming time. Hope this helps someone.

Hi,
Try pinging the mail server.

Is there meant to be a mailserver running on the localhost, or is the mailserver configuration being ignored? If you're having problems with configuration this JDBC / Javamail Setup may help ...

I too had a similar issue of mail not being sent and got the following message

javax.servlet.ServletException: Could not connect to SMTP host: localhost, port: 25

I had to check my application's context.xml in /webroot/META-INF

The problem was "Session" was "session". I changed small "s" to caps "S".

Location 1:
<Resource name="mail/Session" type="javax.mail.Session"/>

Location 2:
<ResourceParams name="mail/Session">
<parameter>
<name>mail.smtp.port</name>
<value>25</value>
</parameter>
<parameter>
<name>mail.smtp.host</name>
<value>smtp.myservername.com</value>
</parameter>
</ResourceParams>

Thanks to Torque for scratching his head.
