If you have an IVR application on POM, which is complied with Avaya Orchestration Designer 7.1 or earlier version, then it fails to get launched. Also, there might be duplicate runtime support jar files in the Application server - tomcat ($APPSERVER_HOME/lib) or websphere ($WAS_HOME/lib/ext/). You can verify the error in the $VP_HOME/VPMS/logs/avaya.<text/email/sms> log, or in the Application server logs - tomcat ($APPSERVER_HOME/log/), or websphere ($WAS_HOME/profiles/profile/logs/server1/).
