Problems on sending mail on Websphere Application Server Community Edition

Question

Hi, i am using the following class for sending mail:-
/**This class encapsulates mailing to any person. it defines method that takes parametres
* such as mail server address,sender and recipient address, userid and password of the
*  SMTP account
package src;

/** Convert a list of addresses to an ArrayList. This will work

// For each word found in the line

}Then i am using the following code snippet in a servlet to send mail by using the static send function of the above class.
try {
            src.Mailer.send("smtp.mail.yahoo.co.in","[email protected]","[email protected]","gaurav_s_pandey","tinGSPyahootin","Subject of Servlet Mail","This is the mail sent by servlet run on geronimo");
            out.println("Request sent Successfully!!!");
        } catch (MessagingException ex) {
            out.println("Error Sending Request!!! Check Network Settings!!!");
        }My problem is that it is not working on Websphere ApplicationServer Community Edition ,but the same code and servlet is running and sending mails as desired on Apache Tomcat...
Can some one help me plzzz as i have to make it run on WAS CE only and not tomcat....

Answer 1

You didn't say anything about what exactly "not working" means.
Some details would help debug the problem.
My understanding is that WebSphere Community Edition is essentially just
Apache Geronimo. I believe Geronimo has its own version of JavaMail that
might not work as well as the Sun version that is usually included with Tomcat.
If that's the source of the problem, you'll need to ask for help in the Geronimo
support forum.
