I've just run the Endevor Web Services install script after customize ENWSInstallOptions.properties and applying all the latest PTFs.(post V18.0.12 maintenance) , and I found out that Tomcat/shared directory is missing, what's going on ?
For V18.0.12 - AKA the V18 GA release, Endevor libraries can be found under $ENDEVOR_TOMCAT_INSTANCE/shared after the Web Services installation.
For post V18 GA release (after you apply the latest post V18.0.12 maintenance PTFs) - The Endevor libraries are now packaged into EndevorService.war to make easier deployment. You will no longer find $ENDEVOR_TOMCAT_INSTANCE/shared after web services installation.
