JavaMail Error: javax.mail.NoSuchProviderException: smtp

[Anil Giri]

Hi,
I am using JavaMail API to send mail using Gmail Server.
The code runs fine from my Development environment, which is Eclipse using JRE 1.6 and JavaMail 1.4.3 and Tomcat 6.

But I build my code for using the compatibility option for Tomcat 5.5.
My production server has following specs.

Tomcat 5.5
JRE 1.4
JavaMail 1.4.3
Java Actication Framework 1.1.1

But there seems to be some issue with my JavaMail Setup. Though the mail.jar file and activation.jar file is in the Tomcat Lib.

Following is the debug log:

Any help would be appreciated.
