Setup Email Notification

[Varun Parakh]

Hi,
I have a 3rd party application war file which we deploy using standard tomcat configuration. We placed the 2 files under the webapps/lib folder of the application.
URL is like http://<servername>:<port>/<appid>/monitoring

Now the documentation tells me to run the Resource name tag in the Tomcat server.xml (<tomcat basedir>/conf/server.xml) as below

<Resource name="mail/JMMailSession" auth="Container" type="javax.mail.Session"
mail.smtp.host="stmp.mail.com"
mail.smtp.user="userabc"
mail.from="no-r...@abc.com"
/>

and put the

<Parameter name='javamelody.admin-emails' value='a...@xyz.com,adm...@xyz.com' override='false'/>
<Parameter name='javamelody.mail-session' value='mail/JMMailSession' override='false'/>

under context.xml file. I did that and still not able to check if the email if working.

Below is the complete server.xml after adding the resource name tag.

Thanks,
Varun

Hi Varun,

The user's guide says to add the mail session in the tomcat context of your webapp (xml file located in <tomcat_home>/conf/Catalina/localhost/ or in <tomcat_home>/conf/server.xml). [1]
You have not done that.

You can for example, add the following:

<Resource name="mail/JMMailSession" auth="Container" type="javax.mail.Session"
mail.smtp.host="stmp.mail.com"
mail.smtp.user="userabc"
mail.from="no-r...@abc.com"
/>

next to

<Parameter name='javamelody.admin-emails' value='a...@xyz.com,adm...@xyz.com' override='false'/>
<Parameter name='javamelody.mail-session' value='mail/JMMailSession' override='false'/>

Hi Emeric,

I made the changes to server.xml file as you mentioned. (under <tomcat_home>/conf/server.xml). What would be the way to test it? what time of the day does it sends email out and in case of any errors will it write to catalina.out?


Now the file looks like :

  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

    <Resource name="mail/JMMailSession"
              auth="Container"
              type="javax.mail.Session"
              mail.smtp.host="outbound.abc.com"
              mail.smtp.user="abcdef"
              mail.from="no-r...@abc.com" />
  

    <Parameter name='javamelody.admin-emails' value='a...@xyz.com,admin2@xyz.com' override='false'/>  
    <Parameter name='javamelody.mail-session' value='mail/JMMailSession' override='false'/>

Hi,

As said in the log and in the user's guide, you need to add the iText dependency in your webapp.
For example, download the iText file and copy it into the WEB-INF/lib directory of your webapp.
