SMTP Appender problem

[krishnakumar K R]

Hello all,

I'm using mail appender in my application. But not able to get it working. I have some other appender(file) also but it is working fine.

Log4j version is 1.2.12. java version 1.4.2_05.

It throws the following exception ::
Exception in thread "main" java.lang.NoClassDefFoundError: javax/mail/Multipart

The appender configuration is below ;;;
---------------
<appender name="Mail" class="org.apache.log4j.net.SMTPAppender">
<param name="Threshold" value="info"/>
<param name="To" value="mail id "/>
<param name ="From" value="mail id"/>
<param name="Subject" value="LOG4j mail testing"/>
<param name="SMTPHost" value="smtphost"/>
<layout class="org.apache.log4j.PattrenLayout">
<param name="ConversionPattern" value="%d %-5p %-17c{2} (%30F:%L) %3x - %m%n"/>
</layout>
</appender>

Thanks for your help.

You need to install the JavaMail API, which you can download from java.sun.com. It usually comes in two jar files, named mail-{version}.jar and activation-{version}.jar.

Hello,

After placing the Mail.jar and activation.jar in the classpath the exception disappears..But the no mail has been sent. Did i miss any thing in my configuration file?

Please guide me..

Several possible problems suggest themselves:
- you've misspelt the class name of the appender
- there is no proper address to send the email to
- Is your mail host really named "smtphost" ?

Hello,

Thanks for ur reply..
The probrlm is every logging requests made to the Mailappender is with Level below ERROR, hence no mails have been sent.So once i made some requests with FATAL it worked

Thanks,
Krish..
