Thank you for your visiting.
With the URL ‘http://localhost:2990/jira/plugins/servlet/fileUpload?versionId=*’, I can upload the file and visit the result page sussessfully.
But after installing the add-on to test environment, I got a 404 dead link with the similar URL ‘http://IP:8080/plugins/servlet/fileUpload?versionId=*’.
I set the base URL using the method applicationProperties.getBaseUrl( ).
How to get a correct link to the servlet ? Thank you.
And I found a similar question posted last year still unresolved.Jira Dead Link Problem.
