OpenEMM 2013 and 2013 R2 do not work with Tomcat 7. OpenEMM 2013 needs Java 6 (unless you apply the patch in subdirectory Updates at SourceForge), OpenEMM 2013 R2 needs Java 7.

Then the manual is wrong as it says:
Since OpenEMM is a web application using Java, it requires a web container like Tomcat. OpenEMM 2014
was only tested with Tomcat 7.
Download the latest binary distribution of release 7 from http://tomcat.apache.org. The core package is
suffient. The examples here use Tomcat 6.0.32 – you should adapt them to the latest version of Tomcat
7 as needed.
 Create
I don't know why an "OpenEMM 2014" is mentioned here ("OpenEMM-2013_InstallAdminGuide").

I wasted a complete day trying to get OpenEMM 2013 (updated from 2011) to run with Tomcat 7. :(

Oops, there was a mix up in the paragraph with the document version fo OpenEMM 2015. I just put a correction online, thanks for the hint! BTW, OpenEMM 2015 was just launched (and runs with Tomcat 7 and 8 ).
All times are UTC+01:00
