Unable To Send Email Report In VDP 6.1.4

This issue is applicable to 6.1.4 only. Here, you will be able to send a Test email, however, the scheduled email reports are not sent. In the vdr-server.log, you notice the following NullPointerException.

In the GUI you might see:
"Send email summary report error: Failed to send the email summary report. Reason: null"


ERROR [http-nio-8543-exec-6]-services.EmailConfigServiceWS: Unable to trigger test email java.lang.NullPointerException

To fix this:

1. Download the zip file from this link here.
2. The md5 hash for this is: 90a57acb1404cdff68181b6768d3b539 Verify if this is the same on the downloaded zip
3. Use WinScp and copy this file to the /root folder of VDP
4. From SSH of the VDP appliance stop the tomcat service using:
# emwebapp.sh --stop

5. Backup the original vdr-server.war file using this command:
# cp -p /usr/local/avamar/lib/vdr-server.war /root/vdr-server.war_ORIG

6. Copy the patched binary using this command:
# cp /root/vdr-server.war /usr/local/avamar/lib/vdr-server.war

Make sure the permission for this patched binary is same as the original file.

7. Remove the vdr-server* files from tomcat using:
# rm -R /usr/local/avamar-tomcat/webapps/vdr-server*

There will be two files under this webapps directory for vdr-server. Verify before removing and these will be recreated once tomcat is restarted.

8. Start the tomcat service using:
# emwebapp.sh --start

9. The vdr server initialization takes a while and then you should be able to connect to VDP in web client and test your email reporting.

If this still does not work, open a case with VMware support. Hope this helps!
