SMTPAppender in log4j.xml

Question

I apologize if this is not the correct thread for this post.
I'm sure servlet developers can help me. Trying to get the org.apache.log4j.net.SMTPAppender class to work in a servlet environment. I have all jars required mail.jar, activation, and log4j-1.2.8.jar.
Here is my defined appender:
<appender name="SMTP" class="org.apache.log4j.net.SMTPAppender">
          <param name="To" value="[email protected]"/>
          <param name="From" value=" "/>
          <param name="Subject" value="Servlet Error"/>
          <param name="SMTPHost" value="mail.favroweb.com"/>
          <param name="BufferSize" value="100"/>
          <param name="Threshold" value="DEBUG"/>
          <layout class="org.apache.log4j.PatternLayout">
               <param name="ConversionPattern" value="=[%d{DATE}]%nServer hostname: %{server.hostname}%n%-5p %c{3} - %m%nThread name: %t%n"/>
          </layout>
     </appender>
and the logger:
<logger name="com.favroweb.resume.ResumeBuilder" additivity="false">
          <level value="DEBUG"/>
          <appender-ref ref="A2"/>
          <appender-ref ref="SMTP"/>
     </logger>
I plan on only logging ERROR and above from this Logger but am using DEBUG for testing.
A2 is a DailyRollingFileAppender and the class com.favroweb.resume.ResumeBuilder logs to this just fine.
If anyone has any working examples. Please advise.

Answer 1

That's pretty much what I have, except I'm using the old text configuration instead of the XML configuration. Only significant difference is that I have something in the "From" parameter.
It would help if you said what was wrong. My first guess would be that you can't send an e-mail without a From address, but besides that there's also the possibility that your server won't relay to your To address and other similar problems. SMTPAppender works for me but I'm just sending to an address in the same domain so I don't have any relaying or authentication issues.
