Tomcat won't be discovered

Question

In my environment a Tomcat 7 installation on Ubuntu 14.04. won't be discovered. In the first step I just want to test basic Tomcat monitoring, so BeanSpy is not installed on the system.
The following Tomcat packages are installed on the system:
joachimm@ubu-001-127:~$ dpkg -l *tomcat*

un  tomcat7-user                  <none>              <none>              (no description available)
The following JEE Management Packs are installed:

  True Microsoft.JEE.Tomcat.Library    JEE Tomcat Web Application Server Library 7.3.2135.0
When looking into the discovery rule "Seed of a configuration for Tomcat 7.x application server on Unix/Linux" there's a filter for the attribute MajorVersion:
  <TargetSystem>$Target/Property[Type="Unix!Microsoft.Unix.Computer"]/NetworkName$</TargetSystem>
  <Uri>http://schemas.microsoft.com/wbem/wscim/1/cim-schema/2/SCX_Application_Server?__cimnamespace=root/scx</Uri>
  <Filter />
  <SplitItems>true</SplitItems>
  <Interval>14400</Interval>
  <SyncTime />
  <FilterProperty1>//*[local-name()="Type"]</FilterProperty1>
  <FilterValue1>Tomcat</FilterValue1>
  <FilterProperty2>//*[local-name()="MajorVersion"]</FilterProperty2>
  <FilterValue2>7</FilterValue2>
On my system the attribute MajorVersion is empty though:
joachimm@ubu-001-127:~$ pushd /opt/microsoft/scx/bin/tools/
/opt/microsoft/scx/bin/tools ~ /opt/microsoft/scx/bin/tools ~
joachimm@ubu-001-127:/opt/microsoft/scx/bin/tools$ . ./setup.sh
joachimm@ubu-001-127:/opt/microsoft/scx/bin/tools$ ./omicli ei root/scx SCX_Application_Server
instance of SCX_Application_Server
    Caption=SCX Application Server

    DiskPath=/var/lib/tomcat7/
    Type=Tomcat
    Profile=
    Cell=
    Node=
    Server=
    IsDeepMonitored=false
    IsRunning=true
Any idea why the MajorVersion attribute is empty and how to fix this?

Hi Joachim,
There is a known issue in which Tomcat installed from a package (deb / rpm) does not discover version information. This issue has been corrected and will be released in the UR4 version of the OpsMgr UNIX/Linux agents.
The work around is to insert the RELEASE-NOTES file from a source distribution into the installation directory of the tomcat install. The file for a tomcat 7.0.52 installation can be found here
http://archive.apache.org/dist/tomcat/tomcat-7/v7.0.52/
