Gregory,
Thank you for the files. The deployment problem might be related to the ‘In-workspace’ mode.
Can you please ask the user to deploy the project in ‘Classic’ mode instead and check if the deployment works?
Double click on the Websphere server in the Servers view to open the Overview page.In the ‘Advanced publishing settings’ section, select ‘Classic’ Deployment mode and save the changes.
Apologies for inconvenience caused. Please let us know how it works.
