JavaMail on WebSphere

Creating a mail resource - whereby you use JNDI to get a context that you send email through - is surprisingly easy in WebSphere, at least for my minimal requirements :-)

I reused the Built-in Mail Provider @ server level:

...and then created my own mail session:

Mail Providers > Built-in Mail Provider > Mail Sessions

• Name = MyMailSession
• JNDI name = mail/MyMailSessionMail
• transport host = 192.168.192.5
• Mail transport user ID = wiki
• Mail transport password = wiki
• Enable debug mode = ticked

Next I created a very simple servlet, whose doGet method grabs the JNDI context and then uses the JavaMail API to send an email:

I pulled in the JNDI reference straight from the web container, but I could have used an environmental reference from the web.xml file:

Because the SMTP debugging was on I got output that looked like the following and that resulted in an email being sent to me :-)
