Last month i migrate a from Portal V7.0.2 to V8.0.1.
Today i receive a task to integrate some applications using WAB (Web Application Bridge).
When i launch the Administration interface the Virtual Application Manager portlet was not there.
I search for a solution but at the end i opened a PMR.
This kind of problem was reported and to fix just run the following tasks:
ConfigEngine.sh action-create-library-wp.vwat.engine
ConfigEngine.sh action-create-resource-environment-provider-wp.vwat.engine
ConfigEngine.sh action-create-resource-environment-provider-custom-property-wp.vwat.engine
ConfigEngine.sh action-deploy-portlets-admin-wp.vwat.manager
ConfigEngine.sh action-create-ear-wp.vwat.servlet/ear
ConfigEngine.sh action-deploy-portlets-wp.vwat.webdock
Restart the Portal Server
