vSphere Client plug-in does not show up in the UI after registration in VCSA 6.7 U2 or above

Products

• VMware vCenter Server

Issue/Introduction

Symptoms:

• You have registered a vSphere Client plug-in in VCSA 6.7 U2 or above, and you observe that the plug-in is not present in the vSphere Client UI.
• The log files report that the plug-in is deployed successfully and the plug-in is available in the Client Plug-Ins view in the Administration category.

Environment

VMware vCenter Server Appliance 6.7.x

Cause

The vSphere Client server is not able to retrieve the "META-INF/MANIFEST.MF" file from the plug-in's UI (.war) bundle.

Resolution

When constructing a plug-in .war file, the plug-in developer needs to include a zip entry for each directory and file of the bundle. For example, if the bundle has a "META-INF/MANIFEST.MF" file, two entries need to be created - one for "META-INF" directory and one for "META-INF/MANIFEST.MF" file.
