Ok, so found the solution.
need to uncomment the following section in "em-jetty-config.xml" file
_________________________________________________________________
<!-- Configure non-secure http listener for the Jetty Server -->
<!-- using an extension of org.mortbay.jetty.bio.SocketConnector -->
<!-- that doesn't throw NPE on EM shutdown -->
<Call name="addConnector">
<Arg>
<New class="com.wily.webserver.NoNPESocketConnector">
<Set name="port">8081</Set>
<Set name="HeaderBufferSize">8192</Set>
<Set name="RequestBufferSize">16384</Set>
<Set name="ThreadPool">
<New class="org.mortbay.thread.BoundedThreadPool">
<Set name="minThreads">10</Set>
<Set name="maxThreads">100</Set>
<Set name="maxIdleTimeMs">60000</Set>
</New>
</Set>
</New>
</Arg>
</Call>
_________________________________________________________________
and then restart the MoM/EM. This will enable MoM/EM to listen on port 8081.
VERY IMPORTANT NOTE:
So, along with the new WebView property that should be configured which is mentioned in this doc, I think CA also needs to add to that doc that if you are using "em-jetty-config.xml" for your MoM/EM then the above section needs to be uncommented.
Thanks a lot for your helps guys, especially Keith.W
